I am trying to convert some DEM in .tif image to polygon geometries representing 3 dimensional triangles that isWell-known text (WKT) - 3D (x,y,z).
What is the work flow for doing this?
You can use the TINGenerator to create triangles (3D polygons) from a single band numeric raster and use the GeometryExtractor to extract WKT representation as a feature attribute for each triangle.
@takashi,thank you for your support.
I appears am not getting is right as there is no output produced.See me screen below....What am I missing?
I am new to this technology unfortunately,I couldn't get this to work.
Permit me to ask for a detailed step-by-step guide on doing it?GeoTiff to 3D WKT
@shintakuWould you mind attache your workspace as it is now?That way the 亚搏国际在线官网community experts can help you debug what's missing and how to get it to work.Thanks!
Possibly you've not made a connection between the attribute storing OGC WKT and the attribute "text_line_data" in the destination Text File writer feature type yet.
There are three ways to make the connection.
1.Just drag to draw a link between them.
2.Rename the geometry attribute to the same name as the destination attribute,in the GeometryExtractor parameters dialog.
3.Set the geometry attribute to the destination attribute in the writer feature type.
Hope this helps.
