As I have said earlier GeoTIFF layers (all image based formats are raster formats) are not supported by W3DS module and therefore those are not listed in GetCapabilities response. GeoTIFF layers are served by wms module in octet-stream format (https://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/GIS_Data_Provider_-_User_and_Programmers_Guide#World_Wind_Format_Module)

Actually, text/html is only partially implemented and it should be removed from GetCapabilities response. I'm sorry for any inconvenience.

In our reference client data adding it to a web page is handled here: https://github.com/Cyberlightning/GISDataProvider/blob/master/GIS_Client_xml3d/scripts/scenemngr.js#L346

It could also be useful to study some basics how XML3D works. You can find getting started guide from here: http://xml3d.org/getting-started/

I hope that this answer helps you forward.

Ok, perfect. But now my problem is other.

I'm trying to show in my own xhtml page the sample terrain loaded in my
geoserver.

First of all I have verified the capabilities of my geoserver
http://10.27.8.181:9090/geoserver/ows?service=w3ds&version=0.4.0&request=GetCapabilities

And in the result I can see my layers with their properties. (I only can
see shapefile layers... Why geotiff layers as we have been test are not
shown?)

With this result I want to show my terrain layer...

http://10.27.8.181:9090/geoserver/w3ds?version=0.4&service=w3ds&request=GetScene&crs=EPSG:3047&format=text/html&layers=fiware:terrain&boundingbox=374150,7548900,374550,7549400

With this request (format=text/html) I get a web page and clicking in see
all I can see something black... I supose this is my 3d map without a
texture.

But now I want to do the same in my xhtml page...

With this request:
http://10.27.8.181:9090/geoserver/w3ds?version=0.4&service=w3ds&request=GetScene&crs=EPSG:3047&format=model/xml3d+xml&layers=fiware:terrain&boundingbox=374150,7548900,374550,7549400

I get a terrain.xml3d file that looks like:

<group id="POLYGON" class="NodeClassName"><mesh type="triangles"><int
name="index">0 1 2 2 3 0 3 2 4 4 5 3 5 4 6 6 7 5 7 6 8 8 9 7 9 8 10 10 11 9
11 10 12 12 13 11 13 12 14 14 15 13 15 14 16 16 17 15 17 16 18 18 19 17 19
18 20 20 21 19 21 20 22 22 23 21 23 22 24 24 25 23 25 24 26 26 27 25 27 26
28 28 29 27 29 28 30 30 31 29 31 30 32 32 33 31 33 32 34 34 35 33 35 34 36
36 37 35 37 36 38 38 39 37 39 38 40 40 41 39 41 ...

I want to show this data in my mapbut I can't do that. I have tried to
follow this guide:
https://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/GIS_Data_Provider_-_User_and_Programmers_Guide
but I cant load my data... Other problem that I have found is that when I
try to change the format attribute in my request, the result is a format
error.

i think that I am next to the final solution... Any example of and xhtml
file loading this data and show it in a map will be great.

Thanks for your attention.

Hi,

I believe that we found out what caused error which you reported. It should be fixed in client version available from our source code repository (https://github.com/Cyberlightning/GISDataProvider) and fix will also be released to forge later this week.

Finally I have downaloded a Geotiff file. I have publish my layer in
geoserver correctly. When I try to see this layer in
my GIS_Client_DEM/index.xhtml I can select my layer.

Data of this layer are displayed, but the map is not shwon.

Now, the map is always oading but in the console I get this error:

Uncaught RangeError: byte length of Float32Array should be a multiple of 4

Once this error happens, the map is not loaded.

But the problem is the same.

I have jusd download...

• Entity ID: SRTM1N11W009V3
• Publication Date: 23-SEP-14
• Resolution: 1-ARC
• Coordinates: 11 , -9
• a map. The format file is geotiff. And the the problems are the same
  that i have reported before. In the w3ds tab I obtain the same error:

org.apache.wicket.WicketRuntimeException: Exception in rendering component:
[MarkupContainer [Component id = x3d.objectid]] at
org.apache.wicket.Component.renderComponent(Component.java:2725) at
org.apache.wicket.MarkupContainer.onRender(MarkupContainer.java:1538)

And in the GIS_Client_DEM/index.xhtml I can load the DEM layer, but I
can't see the map. The erros in the javascript console ar the same.

Hi,

We just updated wiki page to clarify some steps in layer publishing process. Updated documentation can be found from here: http://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/GIS_Data_Provider_-_Installation_and_Administration_Guide#GeoTIFF_based_.28DEM.29_data_sets_for_elevation

As stated earlier there are numerous places where you can download digital elevation maps in raster format with included geospatial information. One place is http://earthexplorer.usgs.gov/. We have used SRTM data sets (Data Sets -> Digital Elevation -> SRTM) downloaded from there for testing and developing purposes.

Textures are optional and if you just want to see terrain you won't need it.

Ok.

I only want to see a map in 3D. Where I can to download a compatible map?
In wich format? I need textures too?

Once I have the map, to load the map and show it sould be easy.

Hi,

At the moment W3DS module doesn't support raster data and that reported crash is a known issue. When you use DEM files W3DS module is not used and therefore that error is irrelevant to your real problem.

Did you set Byte Order from publishing tab as stated in setup guide? (https://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/GIS_Data_Provider_-_Installation_and_Administration_Guide)

Is Coordinate Reference Systems set to same value than you data set is?

Does server log some errors when you do requests from the client? By default log file is located at: /var/log/tomcat7/catalina.out

Thanks.

Now I want to view a DEM map, so I have tried to add to geoserver the
"DEM_geotiff_terrain_EPSG3067" geotifmap. The layer name starts with DEM.
The layer is publish correctly, but when I try to see the "w3ds tab" I have
obtained this error:

org.apache.wicket.WicketRuntimeException: Exception in rendering component:
[MarkupContainer [Component id = x3d.objectid]] at
org.apache.wicket.Component.renderComponent(Component.java:2725) at
org.apache.wicket.MarkupContainer.onRender(MarkupContainer.java:1538) at
org.apache.wicket.Component.render(Component.java:2517) at
org.apache.wicket.MarkupContainer.renderNext(MarkupContainer.java:1440) at
org.apache.wicket.MarkupContainer.renderComponentTagBody(MarkupContainer.java:1603)
at ...

Then in my "GIS_Client_DEM/index.xhtml" i can see my layer and i can see
the loaded data details: length, heigth etc. But the map is not shown.

In the chrome console I can see these errors:

RangeError: Invalid typed array length
Uncaught Error: Matrix is not affine
Error: Matrix is not affine
...

What's the problem?

Hi,

First of all you didn't specify which release version you have tried so I assume that you used newest 4.3.3 release.

Different reference clients consume different source data formats which all can be served by one server instance and therefore it is convenient to separate those by simple naming rules. When you use GIS_Client_xml3d/index.xhtml all terrain layers should contain "terrain" in the layer name. Otherwise it will not be visible in the terrain list in the client.

Also it's worth to note that GIS_Client_xml3d/index.xhtml use custom data format for terrain also at the server side and it's most likely that you won't find any ready to use data sets beyond our test assets. Guide how to generate new terrain data for client is documented here: https://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/GIS_Data_Provider_-_User_and_Programmers_Guide#Setup_GeoServer_with_test_data

That being said you probably want to use GIS_Client_DEM version, since that one support also DEM models which are widely available from multiple sources. For example from: http://earthexplorer.usgs.gov/ just to name one.

DEM client requires that terrain layer contains "DEM" in its name for the reasons I explained earlier.
