If you want to draw something like a way (based) on a track or a  
geographic area or node, that is not in the data but manually added,  
the easiest way is to transform to just a Node, Way or Area and inject  
it into the rendering backend via MapData.poiXXX.

For this see the end of

void RoutingListModel::setStartAndTarget(Location* start,
                                          Location* target)

...
   if (DBThread::GetInstance()->TransformRouteDataToWay(vehicle,
                                                        route.routeData,
                                                        routeWay)) {
     DBThread::GetInstance()->ClearRoute();
     DBThread::GetInstance()->AddRoute(routeWay);
   }

You likely do not want to use these methods directly but their  
implementation shows, how to transform a list of geographic  
coordinates into a Way and move it into MapData.

e.g.

     way.SetType(routeType);
     way.SetLayerToMax();
     way.nodes.reserve(data.Entries().size());
     // copy coordinates into vector

and

   data.poiWays.push_back(std::make_shared<osmscout::Way>(way));


If you want to draw something that has no geographic origin like a  
meter, it is better to draw it on top of the image rendered by the  
backend. In the OSMscout2 demo there is the point where the image  
rendered in the background is copied into the foreground. You can  
either render into the backend image before or afterwards into the  
foreground image depending on your needs using the primitives of you  
UI toolkit (in this case Qt).

No problem, further questions :-)?

[Libosmscout-development] Draw path (or way) on Map (MapPainterQt)

[george b <sco...@gm...>]

Hello

Based on the OsmScout2 example, I developed a little application to draw a
simple map. Now I want to draw a (line, path, way) whatever on the map,
based on gps coordinates from a gpx (track) file.

What is the best approach doing this? I read some code about Way, Path and
polyline within libosmscout, But I dont know how to use them within this
library. Or should I use a qml overlay over Map itself? But then things get
tricky to be syncronised to the geo coord.

Any advice is appreciated.

Bye
George

[Lukáš K. <luk...@ce...>]

Hi. Qt support rendering via OpenGL too. You just have to setup 
`setRenderTarget` in MapWidget:

`setRenderTarget(RenderTarget::FramebufferObject);`

I already using it in Sailfish OS port - it render map to tiles, 
convert it to QPixmap (should be placed in graphic card memory) and then 
render it to screen... It is fast and fluent. 

But these changes are not merged to upstream repository yet. It will take some 
time when it will be ready... 

Current OSMScout2 demo application (Qt) send rendered map to graphic card 
every time when you move map. It is slow on mobile platforms and it is not 
suitable for fluent move animations. But you can use it as good start.

The OpenGL backend is just a proof of concept. It is neither good  
OpenGL and it is far from feature complete. The cairo, Qt and iOSX  
backends are currently the way to go. Though an OpenGL in principle  
makes sense if done well.

[Libosmscout-development] ESRI Shape Files

[Nicholas H. <ni...@ze...>]

Has anyone had experience converting ESRI Shape files into a format that libosmscout can import? I am wanting to take some UK Ordnance Survey ESRI Shape files and import them with libosmscout.

Thanks!

Re: [Libosmscout-development] Show US Counties

[Tim T. <ti...@fr...>]

Hello Nicholas,

> Is it possible to color US Counties a specific color, or is this  
> data not even provided with OSM?

There are multiple answers:
* The data is in principle in OSM, at least there is a tagging for it.  
See https://wiki.openstreetmap.org/wiki/Key:boundary
* libosmscout currently evaluates boundary:administrative for the  
location index.
* Despite coastlines (which are similar but not the same), libosmscout  
does not has a special index for boundaries.
* Drawing coastlines and boundaries is problematic, since they have  
fractal attributes. To draw them fast in low zoom levels you have to  
simplify the polygons.

The map.ost currently has the following definitions:

   // Do not delete the following type, they are required by the  
GenLocation import step
   TYPE boundary_country
     = WAY AREA ("boundary"=="administrative" AND "admin_level"=="2") OR
       RELATION ("type"=="boundary" AND "boundary"=="administrative"  
AND "admin_level"=="2")
       {Name, NameAlt, AdminLevel}
       MULTIPOLYGON IGNORESEALAND

   TYPE boundary_state
     = WAY AREA ("boundary"=="administrative" AND "admin_level"=="4") OR
       RELATION ("type"=="boundary" AND "boundary"=="administrative"  
AND "admin_level"=="4")
       {Name, NameAlt, AdminLevel}
       MULTIPOLYGON IGNORESEALAND

   TYPE boundary_county
     = WAY AREA ("boundary"=="administrative" AND "admin_level"=="6") OR
       RELATION ("type"=="boundary" AND "boundary"=="administrative"  
AND "admin_level"=="6")
       {Name, NameAlt, AdminLevel}
       MULTIPOLYGON IGNORESEALAND

   TYPE boundary_administrative
     = WAY AREA ("boundary"=="administrative") OR
       RELATION ("type"=="boundary" AND "boundary"=="administrative")
       {Name, NameAlt, AdminLevel}
       MULTIPOLYGON IGNORESEALAND

The stylesheet in turn:

   [TYPE boundary_country] WAY {color: @countryBorderColor;  
displayWidth: 0.4mm; dash: 7,3;}

As you see this only renders ways, I'm not sure if you would proper  
areas to fill from the current processing.
There is also boundaries.oss you can take a look at (see corrected  
version below).

* On the TODO list there is an entry to copy parts of the  
GenWaterIndex functionality to generate further indexes for  
boundaries. This would allow better and faster visualisation.

Fixed boundaries.oss

Re: [Libosmscout-development] Many Questions

[Tim T. <ti...@fr...>]

Hello Michael,

>> I can't build the demos i get an Link error
>> agg:font_engine_free_type_base::prepare_glyph (debian jessi build with
>> autobuild cmake in jessi to old)

I can reproduce the problem using a docker image of debian jessie. The  
problem is, that during the build of libosmscout-map-agg the  
freefonttype support for agg is not found:

checking for libagg support library 'aggfontfreetype_pic'... no
checking for libagg support library 'aggfontfreetype'... no

Later on, at the time the demos are linked, the fontfreetype support  
cannot be found during linking.

I (again) tried to find out, why the detection code does not work, but failed:

The autoconf check tries to compile this little program:

| /* confdefs.h */
| #define PACKAGE_NAME "libosmscout-map-agg"
| #define PACKAGE_TARNAME "libosmscout-map-agg"
| #define PACKAGE_VERSION "0.1"
| #define PACKAGE_STRING "libosmscout-map-agg 0.1"
| #define PACKAGE_BUGREPORT "ti...@te..."
| #define PACKAGE_URL ""
| #define STDC_HEADERS 1
| #define HAVE_SYS_TYPES_H 1
| #define HAVE_SYS_STAT_H 1
| #define HAVE_STDLIB_H 1
| #define HAVE_STRING_H 1
| #define HAVE_MEMORY_H 1

| #include <agg2/agg_font_freetype.h>
| int
| main ()
| {
|  agg::font_engine_freetype_int32 fontEngine;
|   ;
|   return 0;
| }


using the following command line:
configure:16431: g++ -o conftest -g -O2 -std=gnu++11 -Wall -Wextra  
-Wpointer-arith -Wundef -Wcast-qual -Wcast-align -Wredundant-decls  
-Wno-long-long -Wunused-variable -I/usr/include/agg2   
-I/usr/include/freetype2    -laggfontfreetype -lagg_pic  conftest.cpp

But this fails with:

/tmp/ccSMYhDX.o: In function `font_engine_freetype_int32':
/usr/include/agg2/agg_font_freetype.h:195: undefined reference to  
`agg::font_engine_freetype_base::font_engine_freetype_base(bool,  
unsigned int)'
/tmp/ccSMYhDX.o: In function `~font_engine_freetype_int32':
/usr/include/agg2/agg_font_freetype.h:185: undefined reference to  
`agg::font_engine_freetype_base::~font_engine_freetype_base()'

Later on the configure script tries the same with the non-pic version  
of the library.

I do not know, while linking here fails and how to change the call to  
get it to work. I do not see any bugs in debian regarding this either.  
Nor any hints int "the internet" how to link correctly.

readelf -Ws /usr/lib/libaggfontfreetype_pic.a | c++filt

show that the symbols are there...

HELP!

[Libosmscout-development] Recent changes

[Tim T. <ti...@fr...>]

Hello,

I pushed some changes:
* I number of changes to get the documentation autodeployed. I also  
moved some documentation from the git repository and the documentation  
from the standard.oss file to the web site.
* The automatically generated doxygen documentation is also now part  
of the web site
* Some cleanups by Lukáš to the CMake support (Travis build now green again!)
* The MercatorProjection was changed: Instead of passing lon/lat it  
now get passed a GeoCoord (see recent discussion on the list).
* Lukáš also enhanced the Mercator (and Tile-) Projection with an  
additional flag. If the flag is set, the geometric projection code  
gets simplified and will in return we faster. This will only work on  
high zoom levels. So make sure, you understand what is happening!
* New methods IsDirectory() and ExistsInFilesystem(). USed by the  
importer to generate better error messages in one case.
* Contour labels (the names of roads :-)) will now be repeatedly drawn  
by the Qt, cairo and agg backend. This will result in more labels  
rendered but the rendered map looks better. Since there is no API  
change it should be possible to implement this for the iOSX backend,  
too. Possibly it already is implemented? Can one of the iOSX users  
give me same feedback on this? The values for offset and spacing are  
store din MapParameter. It is possible to make this values for certain  
situations changeable via style sheet. Please make an bug/issue if you  
need this.
* Added BORDERTEXT primitive, which allows to render a label on an  
area border. While this works the result is not as fancy as it sounds.  
Please try this out and give some feedback what is missing (offset of  
rendering to border, rendering direction, multiple labels,....)

I have added more issues to the GitHub bug tracker. Some are tags with  
Milestone 2016. This a issues for things on the original 2016 roadmap.  
This does not mean, that these *will* be implemented in 2016 (time...)  
and this does not mean, that no other will be implemented. It is just  
a marker and of course I'll try to make plan vs. reality not look too  
bad.

I'll also participate to the OSM Sommercamp in Essen  
(https://wiki.openstreetmap.org/wiki/SommerCamp_2016). Such events  
allow me to work a longer, continuous time and bigger changes.  
Currently I plan to work on
* HTML Reports for (some) import errors. This reports could be used  
for mapper as imput.
* Routing over multiple databases.

Of course you can still vote for other important things :-) And of  
course I'll be also there to answer questions from people planing to  
use/ already using libosmscout.

Re: [Libosmscout-development] Many Questions

[Tim T. <ti...@fr...>]

Hello Michael,

> Hello all together,

Yes. See ConsoleLogger in Logger.h. You have to write your own by  
either deriving from StreamLogger or Logger. You then call  
Log.SetLogger() early in your program to exchange the default  
ConsoleLogger implementation with your implementation.

Should work in principle, but there are a number ofknown problems  
under various distribution because of slightly different builds of agg.

Can you send me (or the list) the output of the configure for  
libosmscout-map-agg and the demos (if I understood you correctly the  
libraries builds, but not the demos)? If this doe snot work, I might  
be able to reproduce the problem locally using a docke rimage.

> build with msys2 under windows the import crash

That should not happened either.
* Do you have a callstack?
* Can you start the importer via debugger to get a callstack during the crash?
* Does it crash immediately or later during the import? Can you send  
me the output of the importer in the later case?
* Which import file do you use?

> I think the lib is very good but the documentation... How I  help ?

If you need more information regarding certain topics:
* There should be a demo for most of the common use cases
* If there is no demo or the demo is not "good enough", just ask on  
the list a concrete question. I'll try to answer it and write some  
tutorial or documentation in return.

For example, there is now issue #65:  
https://github.com/Framstag/libosmscout/issues/65 :-)

I'm currently trying - besides many other things - to improve the web  
site by adding more documentation. So it is worth to take a look from  
time to time.

I Try to build an CarPC with Raspberry SDL2 and ffmep. First Try i have 
make it with Mapnik but i have many problems. And is very slow.
this lib is very fast at now.

https://www.openstreetmap.org/node/1685622064

Location: 50.0955649, 8.4947834

=> OpenStreetMap itself has the order lat, lon (which is the most  
common order it seems).

Note that libosmsocct does happly mixes the order :-/ In most cases it  
is lon, lat. Since this is most suprising and very annoying, I added  
the GeoCoord type which has lat, lon in its constructor in that order  
and explicit GetLat() and GetLon() methods. So the internal storage  
order is hidden and for parameter passing you do not always need to  
look at the API of each method. I try the refactor the code, so that  
all methods just get GeoCoord passed but that will still take a while  
since it has rathe rlow priority.

You swap lat and lon. libosmscout is very strange

[Michael N. <ro...@mi...>]

Hello Every Body,

i have copy the cairo sample and generated a database form geofrabirc 
hessen.

But the png is empty why. Zoom have change to serival values. The Search 
found Zeilsheim.

How to enable logging ?

Re: [Libosmscout-development] Using multiple databases or database merging

[Tim T. <ti...@fr...>]

Hello Lukáš,

> Hi Tim. I have question for future development. It is somehow possible
> to use two databases with fully working routing (when route is crossing
> database boundaries)?

Yes and no.

There is currently no code that allows this. However the recent change  
so that nodes (as part of ways or areas) and route nodes have an id  
that is unique independent on the actual import allows in principle to  
look for a specific route node in multiple databases.

There are of course some pre requirements:
* The unique id is generated based on the coordinate. If different  
imports have different resolution of the coordinate the same node may  
get a different unique id.
* The imports needs to have all nodes for the same coordinate since  
the unique id is based on the coordinate and a running number per  
coordinate.
* The imports must overlap. That means that a way or area in the  
"border" must be available in both imports - or at least one node. So  
I route to the "end" of the database, then lookup for the same route  
node in the next database and continue the routing there.

You also need some kind of index that tells you which nodes you have  
to look for in multiple databases, since there is no "look in other  
databases, too"-maker. Such index could either be based on a  
cell-approach (this cell is in the following databases...) or based on  
the actual ids (this id is in multiple databases).

Right. The current OSMScout2 app only allows one one path to one  
databases. Switching database however should be simple to implement. I  
just did not have the time for all the GUI stuff required.

No. The database generation algorithm is complex. There is no simple  
way to patch or merge an database.

[Libosmscout-development] Using multiple databases or database merging

[Lukáš K. <luk...@ce...>]

Hi Tim. I have question for future development. It is somehow possible 
to use two databases with fully working routing (when route is crossing 
database boundaries)? 
I would like to provide prepared databases from my server and integrate 
download manager to application. Something similar to Android Here maps. 
I saw that OSMScout-ubuntu provide download functionality, 
but when I understand it correctly, it can load just one database at start.

Another solution that can be used, is to merge downloaded databases somehow 
(on target device). Or just merge "routing" files? Can you imagine how it can 
be achieved?

I don't have enough time for developing it right now, I am just asking what 
I should write to my todo list :)

Re: [Libosmscout-development] Documentation

[Tim T. <ti...@fr...>]

Hello,

I have now finished some tasks in reaction to Karls documentation request:
* I have (slightly) improved the web page layout, styling and structure.
* I have moved to generate the complete web site from some static web  
site generator. This allows me (and others) to write much of the web  
site in simple markdown. The tool used is Hugo (https://gohugo.io/).
* The web site is automatically redeployed on each central Travis  
build. So if anybody checks in a new or improved markdown document as  
part of the web site or does the same as part of an accepted pull  
request, the content is there as soon as the changes are pushed to  
github. This greatly reduced the effort in comparison to the manual  
approach chosen before.
* The same build process also generates API documentation using  
doxygen. The API documentation is also published to the sourceforge  
web site afterwards, so that the documentation on the web site should  
also reflect the current API.

This does not result automatically in brilliant and complete  
documentation. But it dramatically reduced the effort to improve the  
documentation. I'll in future make sure that while responding to  
questions on the list create or update an corresponding article. Using  
pull requests it should also be rather simple for others to offer  
documentation, too.

It is of course not required to document this way. The OSM wiki or  
similar places can still be used, too. But please at least send me a  
link in this case, so that I can move the documentation to the web  
site in this case.

I hope that these changes help working with libosmscout :-)

As mentioned before the web site is not finished, there are a number  
of glitches and possible improvements. If somebody has the passion to  
improve, do so :-)

Re: [Libosmscout-development] Getting error: libosmscoutimport.so.0: cannot open shared object file: No such file or directory

[Lukáš K. <luk...@ce...>]

Just for completion: 

Linux executable binaries (ELF format) contains some metadata. One of these 
metadata is RPATH variable that can define paths where ld.so should search 
libraries (among other paths). You can print rpath (or change it) by patchelf 
or chrpath tools.

$ pwd
/home/karry/data/cecko/OSM/libosmscout/build

$ chrpath -l OSMScout2/OSMScout2
OSMScout2/OSMScout2: RPATH=/home/karry/data/cecko/OSM/libosmscout/build/
libosmscout-map-qt:/home/karry/data/cecko/OSM/libosmscout/build/libosmscout-
map:/home/karry/data/cecko/OSM/libosmscout/build/libosmscout

You can see that cmake build setup RPATH for binaries ;-) 
And remove it when binaries are installed to standard destination.

Re: [Libosmscout-development] Getting error: libosmscoutimport.so.0: cannot open shared object file: No such file or directory

[Tim T. <ti...@fr...>]

Hello Nicholas,

> I am not completely following you. How do I extend the search path  
> for my session?

OK :-)

During execution of binaries, shared libraries have to be loaded and  
linked during runtime. The mechanism is OS dependent. Under Linux  
normally ld.so (man ld.so) is responsible.

For this it has to find the shared libraries on disk.  It normally  
looks for librarie sin directories like /usr/lib or /usr/local/lib.

The libraries, libosmcout builds, and which are referenced by its  
tools, are normally not placed here (you would need to "install" it).

ld.so however also evaluates the environment variable LD_LIBRARY_PATH  
to look for further locations.

On my system the actual libraries (for the autconf build) are placed  
in src/.libs/ by the build. For example:

[tim:~/projects/OSMScout] master(+14/-5,13)+* ± ls -l libosmscout/src/.libs/
insgesamt 18812
lrwxrwxrwx 1 tim users       17 19. Jun 13:37 libosmscout.la ->  
../libosmscout.la
-rw-r--r-- 1 tim users      958 19. Jun 13:37 libosmscout.lai
lrwxrwxrwx 1 tim users       20 19. Jun 13:37 libosmscout.so ->  
libosmscout.so.0.0.0
lrwxrwxrwx 1 tim users       20 19. Jun 13:37 libosmscout.so.0 ->  
libosmscout.so.0.0.0
-rwxr-xr-x 1 tim users 19255616 19. Jun 13:37 libosmscout.so.0.0.0

So you have to add all these directories to LD_LIBRARY_PATH. Since  
environment variables are inherited, you either set the variable in  
some shell start up script or you have to set it again (and again) if  
you for example open a new console/terminal.

The setupAutoconf.sh script already does set LD_LIBRARY_PATH:

export  
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${PWD}/libosmscout/src/.libs:${PWD}/libosmscout-import/src/.libs:${PWD}/libosmscout-map/src/.libs:${PWD}/libosmscout-map-svg/src/.libs:${PWD}/libosmscout-map-qt/src/.libs:${PWD}/libosmscout-map-agg/src/.libs:${PWD}/libosmscout-map-cairo/src/.libs:${PWD}/libosmscout-map-opengl/src/.libs

So I should be enough to just call ". setupautoconf.sh". It expects to  
be source from the top level directory.

You can of course replace ${PWD} (with is the environment variable  
that points to teh current directory of your shell) with the name of  
the root directory of the your local copy of the libosmscout git  
repository so that it always works.

Other solution:
In my ~/.bashrc I have for example the following lines:

export  
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/projects/OSMScout/libosmscout/src/.libs
export  
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/projects/OSMScout/libosmscout-import/src/.libs
export  
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/projects/OSMScout/libosmscout-map/src/.libs
export  
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/projects/OSMScout/libosmscout-map-svg/src/.libs
export  
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/projects/OSMScout/libosmscout-map-qt/src/.libs
export  
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/projects/OSMScout/libosmscout-map-agg/src/.libs
export  
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/projects/OSMScout/libosmscout-map-cairo/src/.libs
export  
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/projects/OSMScout/libosmscout-map-opengl/src/.libs

(projects/OSMScout being the root directory for libosmscout). This  
does in principle the same for every terminal I start.

Does this help?

Under Linux custom build libraries are not automatically in the  
general search path for libraries, so the loader will not find them.

You have either install the libraries to a place that is in the search  
path (/usr/lib for example) or (simpler) extend the search path for  
your session.

That (and other things) is what the setupAutoconf.sh script is doing:

export  
LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${PWD}/libosmscout/src/.libs:${PWD}/libosmscout-import/src/.libs:${PWD}/libosmscout-map/src/.libs:${PWD}/libosmscout-map-svg/src/.libs:${PWD}/libosmscout-map-qt/src/.libs:${PWD}/libosmscout-map-agg/src/.libs:${PWD}/libosmscout-map-cairo/src/.libs:${PWD}/libosmscout-map-opengl/src/.libs

You must be in the top level directory of the checked out code to have  
the correct value for PWD.

I'll see, that I extend the documentation...

[Libosmscout-development] Getting error: libosmscoutimport.so.0: cannot open shared object file: No such file or directory

[Nicholas H. <ni...@ze...>]

I am trying to compile libosmscout so that I can import pbf files. I have ran autogen, configure, make and make install for libosmscout, libosmscout-import, libosmscout-map, Import, but when I run ./build.sh in the maps folder on my pbf file I get the following:

../Import/src/Import: error while loading shared libraries: libosmscoutimport.so.0: cannot open shared object file: No such file or directory

Is there a reason this would be missing? At what step is this file installed? I tried compiling twice, but that didn’t help.

Running on Debian 8.5 x64

[Libosmscout-development] Recent changes

[Tim T. <ti...@fr...>]

Hello everybody,

the recent push contains a number of changes:
* Lukáš did some smaller changes and especially fixed the Travis build  
(all green again!).

I also pushed the sources for the new web site and also updated the  
web site itself. The new web site have (IMHO):
* A better layout (though it should have some media queries to improve  
the appearance in mobile devices)
* A better navigation structure
* Is better extendable. It is easy to add more documentation, more  
examples and tutorials.
* It uses Hugo, a static web page generator. Hugo also allows to  
create most of the content using Markdown. So it should be easy to add  
e.g. documentation or tutorials without writing any HTML.

Please take a look (http://libosmscout.sourceforge.net/) and give some  
feedback.

Since the sources of the web site are available to anybody (and Hugo  
isn't that difficult to install) it should be easy to make pull  
request with some extensions and additions.

Any improvement is welcomed but for a good start

* Spelling corrections...
* Simple CSS improvements regarding spacing, font sizes...
* Layout improvements...
* Theme improvements (I'm by no means a theme artists. While I like  
themes to be simple it should still be easy to improve the current  
"theme" without making it look like a child TV advertising :-)).
* A cool front page...
* Additional content...

...would be helpful. Just make pull requests...

Next step will be getting the web site to update automatically from  
the Travis build.

After that I'll try to add the doxygen documentation for libosmscout,  
libosmsocut-map and the concrete backends to the web site, too.

I also filled some issues at the github page:

https://github.com/Framstag/libosmscout/issues

and try to fill some more for things that are on my internal TODO list  
are are simple to describe. I'll definitely enforce it for things  
where I need help, issues I'll not be able to fix on my own. So if you  
would like to help, keep monitoring the list. (Btw.: besides the  
sourceforge bug tracker the github bug tracker can of course also be  
used. I'm monitoring both).
