Creating raster and TIN from a terrain dataset
A terrain dataset can be converted to rasters or TINs using the geoprocessing tools from the 3D Analyst toolbar. Why would we need to convert terrain to raster or TIN?
- Starting from large-scale source data, you might want to obtain derivative vector or raster surfaces for small-scale (for example
- You might need a raster surface to use statistical analysis tools from the Spatial Analyst extension.
- You might want to refine and update the surface with new polygon or polyline features having a precision corresponding to the
1:3,000 scale. You will need a TIN with a vertical accuracy corresponding to that scale.
- You might want to visualize your surfaces in ArcScene.
- You might want to ...
