Re: [Geonetwork-devel] Query Maps inserting coordinates

[<pgr...@uw...>]

Regarding the bounding box coordinates selection:
How about incorporating LiveMap ( 
http://tmap.pmel.noaa.gov/~callahan/JAVA/map_v3.0/LiveMap_v3.0.html ) or 
JazPanel ( http://nsidc.org/data/tools/jaz/ )?

The code is available for both of these, and perhaps it wouldn't be too 
difficult to implement.

Re: [Geonetwork-devel] Query Maps inserting coordinates






Hello,

Actually the feature I wanted is the same as you want. A bounding box 
where the user can make his own selection and results shows up, just like 
"ArcCatalog" search. But I thought that it was not implemented so far, so 
I didn't ask about this feature. Maybe that feature can go to user's wish 
list.
Thanks for the tip, I'll try to make some queries using it so I'll see if 
I have the same problems.
Sorry about my bad english.
See ya,
Felipe Costa

Hi, 
I am also interested in this.  As a matter of fact, picking coordinates on 
a map would also be a great feature.  Let's say you start with a map of 
the world, you could zoom in on an area and drag a box around the area of 
interest to submit coordinates.  I've seen applets that perform a similar 
function. 

With respect to your query Felipe, I think that you would have to edit the 
regions.xml file under web/xml/ directory, to add your region and 
coordinates. 

I actually tried this just now, and the location name shows up in the pull 
down menu in advanced search, but the results are not quite what I 
expected.  Perhaps there is some logical problem with the 
overlapping/enclosing coordinates.  Take the following scenario: Out of 
426 total metadata entries, the search returns 9 that overlap, 375 that 
enclose, 370 that are fully outside of and 342 that are a particular 
location (about 0.05 degrees x 0.05 degrees).  It seems to me, that if a 
dataset encloses a location should also overlap it.  Also, evidently, j 
udging from the result numbers, some locations that are fully outside of 
the specified area also enclose it.  How can that be? 

Let's say that some of the datasets have the wrong coordinates specified, 
so that could contribute to the problem - I didn't fully examine all of 
them.  However, I can't figure out why a particular dataset, whose 
coordinates I verified, would show up in both the 'encloses' results as 
well as the 'fully outside of' results. 

Is anyone else having this problem?

[Geonetwork -devel] Query Maps inserting coordinates








Hello Developers,


I'm using a lot geonetwork to discover it's capabilities and thanks for 
you all helping me about my questions. I have one more today.
Is it possible to make a query inserting a pair of coordinates and 
recovering maps that match to this coordinate?
How's that possible? I tried but I couldn't make it. I saw in the advanced 
search a field which have some options like "is in", "is not in","is 
completely out", etc... But I don't know how to use it. Can you explain it 
to me?
Thanks in advance,
Felipe Costa
