          Hello Aggelos,

          We have an issue with the 3D representation of geo data. More specifically,
          the details of the Geoserver we use are:

          • Version: 2.6.0
          • Git Revision: a648a0c32dd4a6998036410e08d24f94cbf9fb7e
          • Build Date: 23-Jul-2015 08:51
          • GeoTools Version: 12.0 (rev 645963cd65a6f5c151722ce012f2a4a6d3b86a44)
          • GeoWebCache Version: 1.6.0 (rev
            1.6.x/8beca4056f2c4873adbf6758b2ab12f65cebf7a0).

          The installation was made by following this guide:

          https://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/GIS_Data_Provider_-_Installation_and_Administration_Guide

          Until now, we have :

          • created a workspace,
          • a store, (Directory of spatial files (shapefiles)),
          • uploaded plenty layers with testing data, mostly from Greece,
          • and a group to gather all.

          Taking advantage of Openlayers, we have created a UI (javascript,Html,css)
          to visualize all the previous layers into a map, giving the ability to the
          user to change also the base map (google streets, google physical,
          openlayers etc).

          Now, we want to take advantage of the W3DS service.

          Although, when we try to enable some of the layers, a Java IOException
          came, that says the shape type is Undefined:

          Caused by: java.io.IOException: Unsuported shape type:Undefined

          org.geotools.data.shapefile.ShapefileFeatureStore.buildFeatureType(ShapefileFeatureStore.java:131)

          org.geotools.data.store.ContentFeatureSource.getAbsoluteSchema(ContentFeatureSource.java:340)

          ... 104 more

          We manage to add some other layers that contains 3D data, but when we made
          a request with w3ds, we got nothing visible as result.

          1. Do you have any sample shape file with 3D data that are valid,
          2. In order to call w3ds service, the url parameters has to be set
          manually, or is there any other way to generate it?
          3. Is there a specific style for the points in 3D representation?

          Any guide will be helpful.

          Thanks in advance,

              Hi,

              Sorry for delay with answer, I have been out of office.

              1. You can find working shapefile with 3D content from test assets (https://forge.fiware.org/frs/download.php/1687/FIWARE-Test_asset_4.4.3.zip). If Geoserver doesn't recognize your shapefile it's probably somehow corrupted or it uses data types that are not implemented to shapefile reader. I recommend you to use Postgresql/PostGIS combination since that's significantly faster than shapefiles.

              2. Some parameters need to be defined by user / developer, for example layer name. It's just client logic and examples for that logic can be found from reference client (https://github.com/Cyberlightning/GISDataProvider/blob/master/GIS_Client_octet-stream/scripts/scenemngr.js#L301) and also from Openlayers. It's also worth to notice that some parameters change only with request type and those need to be set by user/developer. You can also use Apiary documentation (http://docs.gisdataprovider.apiary.io/#) to check needed parameters and test your requests. You might also find Geoserver documention to be usefull (http://docs.geoserver.org/)

              3. Is there a specific style for the points in 3D representation?

              I'm not sure what you mean with this last one? If you use points in 3D representation as a data source for terrain elevation then those points are visualized by 3D engine and you don't need to define any style for it. Just to make sure, Openlayers is not a 3D engine, so you need to use something else for visualization or enhance Openlayers functionality by your self.

              BR.
              Juha
