Thanks Ferdinando: That sounds very interesting :-) If your lab / students produce any publications please let us know - we will be happy to link to them in a blog post and so on. If you had a pdf about ARIES we could also list that as a case study.

Hi Mark,
Unfortunately, depending on the WFS server, and the backend datasource
it is using it might report the geometry type as a specific type, or
just as a generic geometry type, which I am guessing is happening in
this specific case.
One option would be to "morph" the feature type you get back from the
WFS and explicitly set its geometry type to point. For example:
SimpleFeatureType schema = ...;
SimpleFeatureTypeBuilder tb = new SimpleFeatureTypeBuilder();
tb.setName( schema.getName())
tb.setCRS( schema.getCoordinateReferenceSystem());
for ( AttributeDescriptor at : schema.getAttributeDescriptors() ) {
String name = at.getLocalName();
Class type = at.getType().getBinding();
if ( at instanceof GEometryDescriptor ) {
type = Point.class;
}
tb.add(name,type);
}
schema = tb.buildFeatureType();
And then create the shapefile with that schema.
A second option if you are using geoserver is to use the SHAPE-ZIP
output format, which gives you back a zipped shapefile. Not sure if you
are using geoserver though.

Hi,
I'm new to geotools. I'm trying to read from a WFS and write the data
to a shape file. Reading from
the WFS seems to be working fine, but when I go to create the
shapefile's schema I get the following
exception:
toShpAction:IOException org.geotools.data.DataSourceException: Cannot
create a shapefile whose geometry type is class
com.vividsolutions.jts.geom.Geometry
org.geotools.data.DataSourceException: Cannot create a shapefile whose
geometrytype is class com.vividsolutions.jts.geom.Geometry
at
org.geotools.data.shapefile.ShapefileDataStore.createSchema(ShapefileDataStore.java:804)
at
hec.dgt.plugins.WfsToShpPlugin.toShpAction(WfsToShpPlugin.java:303)
at
hec.dgt.plugins.GageToShpPlugin.doDownload(GageToShpPlugin.java:49)
at hec.dgt.DgtFrame.downloadData(DgtFrame.java:1076)
From what I've been able to find, this error can occur when you're
returned more than one geometry type,
but in this case, at least as far as I'm able to determine, I'm only
getting points back.
ShapefileDataStore dest;
try
{
dest = new ShapefileDataStore(f.toURI().toURL());
}
catch (MalformedURLException e)
{
System.out.println("toShpAction:MalformedURLException "+e);
e.printStackTrace();
return;
}
try
{
dest.createSchema(schema);
}
catch (IOException e)
{
System.out.println("toShpAction:IOException "+e);
e.printStackTrace();
return;
}
I'm using geotools 2.5.5 and Java 1.6 with my code running on windows xp.
Thanks

Yes that does help alittle yes.
However, i still don't know what to do when i see the
- <dependency>
<groupId>javax.media</groupId>
<artifactId>jai_core</artifactId>
- <!-- The version number is specified in the parent POM.
-->
<scope>provided</scope>
- <!-- Users should execute JAI installer.

<artifactId>jai_imageio</artifactId>
- <!-- The version number is specified in the parent POM.
-->
<scope>provided</scope>
- <!-- Users should execute JAI installer.
-->
</dependency>
i've downloaded both the JMF and JAI and installed it but i don't know what
to do with those pom dependecies. What do i need to do exactly?
Also, the gt-epsg-wkt does not seem to download as i get errors so i changed
to gt-epsg-hsql, is that OK?
I've compied the .shp file and the other files but when i run the app and
select the .shp file nothing appears. but instead i get the following in my
output pannel:
[Fatal Error] :1:8: The processing instruction target matching
"[xX][mM][lL]" is not allowed.

NOAA's National Climatic Data Center ( http://www.ncdc.noaa.gov ) is using GeoTools for the 'Weather and Climate Toolkit' : http://www.ncdc.noaa.gov/oa/wct/ , a visualization and data export tool for Weather Radar and Satellite data (with other data types in the works). GeoTools is also used for several internal data processing applications. We've used GeoTools since the old '1.0' version at least 4 years ago.

Justin,
I added a query and added all properties except the geom property. So i get a response without geom. (for this project i don't need the geom). If i need the geom (later this week) i'll try 1.0.
Thanks!
Roy

Hi! As you might see I'm a new user and hope everything goes well with my registration/posting here. I've been digging myself into the GeoTools framework for the past weeks but now can't get any more help on my subject on this list or with google. Here's what I have done so far: 1) put some shapes (railroad network, road network and rivers) with osm data (downloaded from geofabrik) into a postgis database 2) displayed the data with geotools 3) build a graph using the LineStringGraphGenerator and just the railroad network data 4) select two points on the map which are on the graph 5) use Dijkstra to find the shortest way between these points. The problem is point 3) I saw that the graph generated is not well connected and checked this with the GraphPartitioner which had approx. 167 partitions while the dataset (railroad network) hast just 531 entries. At that point I informed myself here and got to know that I have to make a point/node whenever 2 lines crosses and make 4 lines from them (or 3 in a special case) Then I saw 2 possible solutions for this here: 1) Use a PolygonGraphGenerator to get the intersection. 2) Split the linestrings in a seperate method and still build the graph with the LineStringGraphGenerator (code taken from here: http://n2.nabble.com/Splitting-LineStrings-at-their-intersection-td1941502.html http://n2.nabble.com/Splitting-LineStrings-at-their-intersection-td1941502.html ) I tried both and run into the following problems: 1) Graph seems to be way to small, resulting graph is: V=[14, 19, 5, 7, 8, 12, 2, 4, 13, 0, 23, 16, 22, 1, 10, 26, 24, 17, 20] E=[3 (2,1), 21 (20,13), 6 (5,1), 9 (8,1), 15 (14,1), 18 (17,1), 25 (24,1), 11 (10,1)] whenever I want to route I get: Shortest path: null 2) I see 2 problems here, first that it doesn't allways find a path, like in this picture/case: http://sicky.i-networx.de/temp/no_shortest_path.png http://sicky.i-networx.de/temp/no_shortest_path.png 2nd problem is that the path looks very strange: http://sicky.i-networx.de/temp/strange_behavior.png http://sicky.i-networx.de/temp/strange_behavior.png The discussion in the topic I mentioned above unde 2) ended apruptly so I don't have a real solution. So, to take this to and end my questions: 1. What's wrong with the code and/or 2. is there an easy way to route with osm data when you use geotools. Here's all you need to understand my problems: Code for the implementation with the splitting of lines: http://sicky.i-networx.de/temp/TestGUI.java http://sicky.i-networx.de/temp/TestGUI.java Code for the polygon stuff: http://sicky.i-networx.de/temp/TestGUI2.java http://sicky.i-networx.de/temp/TestGUI2.java additional needed classes: http://sicky.i-networx.de/temp/DijkstraShortestPath.java http://sicky.i-networx.de/temp/DijkstraShortestPath.java http://sicky.i-networx.de/temp/SelectionTool.java http://sicky.i-networx.de/temp/SelectionTool.java postgis database dump: http://sicky.i-networx.de/temp/imotris_os.backup I hope that was all and my problems are understandable. If there's something missing or if there are any questions, just drop me a line. Thanks in advance for your help :-) -- View this message in context: http://n2.nabble.com/Building-a-connected-graph-with-OSM-data---Splitting-LineStrings-at-their-intersections-tp3086758p3086758.html Sent from the geotools-gt2-users mailing list archive at Nabble.com. |

right. Long term plan was always to use StreamingParser. Problem begin
it goes OOM and I couldn't use it for the FGDC project.
I'm looking forward to work on it for good, but it'll have to be with
your help wrt the parser.
Aside, can StreamingParser use ParserDelegate as Parser does?

Gabriel

If 3.1.1 is not supported how can you force the wfsdatastore to use a nother outputformat?

We should keep the questions on the user list (so others that know more about raster support than me can answer). My understanding is that you can load any file into a grid coverage (ie raster plus bounds datastructure). And then use the GeoTiff writer to write it out with the correct tags. You should be using an appropriate reader (not just the GeoTiffReader when reading other file formats such as jpeg, jpeg2000, ecw and so on). Thanks for the information; I will add Chinese Academy of Science to the list.

Hi Anniina I had the same problem some times ago 1) Prepare your pyramids using tools from http://www.gdal.org, if you have all images for each zoom level , fine 2) use gdaltindex to create shape files for each pyramid level 3) use gdal_merge, gdal_retile ... for image processing if needed After preparation, you can use geoserver to present your map, either file based or stored in a jdbc database as explained here http://docs.geoserver.org/1.7.x/user/tutorials/imagemosaic-jdbc/imagemosaic- jdbc_tutorial.html I did the jdbc approach and anything works fine.

Afternoon everyone: We have been gradually putting together a front end website for the library (http://www.geotools.org/). The idea is to take some of the burden of the wiki and focus on initial impressions. To that end we have a page devoted to the use of GeoTools; and I am going to look for case-studies, presentations, and importantly who uses the library :-) - http://www.geotools.org/case/index.html To that end could I ask people to reply to this message (or even directly to me if you are shy) with your organization's name.

Basically I created 5 image pyramids for each of the source images. Then I merged by putting the most detailed layer from the less detailed source image as overview layer in my final pyramid. Same for the second source image, again the most detailed layer to the second layer in the final pyramid... (http://docs.codehaus.org/display/GEOTDOC/Generating+Image+Pyramid+Guide) Worked for me (in a JMapPane app though, no idea if geoserver likes it, but should be no problem), just needed a lot of fiddling around with the parameters, to get the zoom factors right.. and lots of cpu time .-).

Hi Luong, > i add the version number to 2.5.6 and instal the JAI under C:\jai-1_1_2 but > i get a build failure: > Please see my earlier reply about version numbers - they only have meaning __within__ a project. The GeoTools version number will apply to all of the GeoTools dependencies in your pom but doesn't mean anything for other dependencies from other projects or developers such as jai, jts, apache etc. > i get an error saying "generics are not supported in -source 1.3 (use > -source5 or higher to enable generics) which hi have never come accrossed > when writting java apps. What does this mean and how can i rectify this? A new maven project created with Netbeans defaults to an early version of Java. To change this: 1. right-click on your project in the Projects window 2. select 'Properties' at the bottom of the pop-up menu 3. select 'Sources' from the list in the properties dialog 4. in the 'Source / binary format' pull-down, choose 1.5 Hope this helps Michael |
