Workflows and dependencies

Due to the different nature of the input data there is a need of specific workflows and tools, here a list of the main libraries used inside this application:

• pg2b3dm Conversion of polyhedron geometries to 3DTiles
• i3dm.export Conversion of point geometries to 3DTiles
• PDAL Processing of point cloud data
• py3dtiles Conversion of point cloud to 3DTiles

The graphs below show the current workflows for each type of data supported: Shapefiles (.shp.zip) and Point Cloud (.las).

    shp_point("Shapefile Point (.shp.zip)")-->geom_point[Geometry Manipulation]-->postgis_point[PostGIS]-->i3dm.export-->3d_intance((3DTiles));
