I would really appreciate some help with the process I am trying to write.
I have a shapefile of routes, I need to create a GPX file for each route. However what I am stuck on is why the 'elevation' tag in the GPX is blank and I need to fix this. I assume I can use PointOnRasterValueExtractor
with the Terrain50Raster which I have in a raster GRID file?
The routes will change so I need the process to be repeatable on a regular basis hence why I am trying to do it the 'correct' way.
Many thanks
+41Hi @safesarahfme
This transformer PointOnRasterValueExtractor generate a list of attribute _band{}.value .
Is empty this information?
Thanks in Advance,
Danilo
Yes, I have a GPX file with the elevation field blank (because it came from a shapefile with no z values).
I have used a GEOTIFF dataset in the 'PointsOnRasterValueExtractor' as well as the GPX file above.
I can get the process to create a new GPX but the elevation data isnt being populated and the attribute_Band{}.value. is empty. Its driving me a bit mad now and I am sure I am missing something simple!!
Help very gratefully received, I have made sure that both the GeoTIFF and the Shapefile that was used to creae the GPX are both in WGS84 (EPSG4326)

Thanks your print. Please use the transformer ListExploder after the PointOnRasterValueExtractor for explode the list 0.

Nice. You can rename this attribute using AttributeManager.
Now please insert the transformer 3DForcer.
