I tried adding CityGML data that is officially available by the state NRW (North Rhine-Westphalia) in Germany. In particular, I was looking forward to add the data of the town Solingen.
At first, there was a problem with the original data. The xml-file starts with:
<gml:boundedBy> <gml:Envelope srsName="urn:adv:crs:ETRS89_UTM32*DE_DHHN2016_NH*GCG2016"> <gml:lowerCorner srsDimension="3">356000.0 5668000.0 45.529</gml:lowerCorner> <gml:upperCorner srsDimension="3">357000.0 5669000.0 77.537</gml:upperCorner> </gml:Envelope> </gml:boundedBy>
However, Cesium Ion was not able to load this data - there seems to be a problem with the interpretation of the srsName.
With the help of this forum and some information on your website I was able to find out that this information should be equal to (see ETRS89 / UTM zone 32N - EPSG:25832). Therefore, I changed the srsName:
Now Cesium Ion was able to upload the data and start the tiling process, but the buildings are placed at the wrong coordinates. I guess, there must be more information in the original srsName than I thought…
Can anybody help me to add this data?
@Shehzan_Mohammed Wouldn’t it be possible to add such data (free and officially available) to the standard Asset Depot?
