Hi all,

 

 

Im a beginner, need your advised.

 

 

i have a DEM data and features (point, line, polygon) data.

 

How to get the height value from DEM and combine it with the features data. Where basically each features will have a Z value.

 

How to do it if the output are in shp. or dgn. format.

 

 

thanks
Hi,

 

 

The SurfaceDraper transformer might be a solution. Input the DEM (a raster or 3D grid points) to POINT/LINES port and input the features (points, lines, polygons) to DRAPE_FEATURES port. Then, output features will be draped i.e. Z value of every vertex will be interpolated based on the DEM.

You can also try using the PointonValueRasterExtracter then use a ListExploder to extract the "value" attribute.
