Raster Meets Point Data

This chapter deals with GDAL utilities that link raster to point data. With gdal_grid, point data can be converted to raster grids. The conversion of raster datasets to point data can be performed with gdallocationinfo and gdal2xyz.py. Other utilities discussed in this chapter are: gdal_fillnodata.py, gdal_proximity.py and gdaldem. We recall that three dimensional point clouds, as a special case of point data, are covered in Chap. 15.
