[Converter] GDAL/PDAL for Geographical Raster/Vector/Pointclouds

[jo-chemla]

This is oriented towards a special class of techy users dealing with geospatial data:

• GDAL [Geo Data Abstraction Library] is used to convert between various geographical raster (image) and vector (combination of polygons/lines/points) formats
  PDAL is used to convert between pointcloud types. Has various CLI integrations or python bindings, eg via a library like rasterio
• PDAL [Point Data Abstraction Library] reads and writes pointclouds, and has readers and writers for multiple pointcloud types. PDAL Binaries can run pipelines which describe which transformations to apply to a pointcloud - could be simple input/output.
