Import of street network data from Prefeitura de São Paulo.
The dataset contains vectorial information about the street network of São Paulo. Each street segment has its name, postal codes and addresses ranges for both sides of the street.
As São Paulo has already good street network coverage on OpenStreetMap, so the import will be focused on fixing street names and improving addressing.
The import will be mostly manual, probably using Tasking Manager or another way to monitor progress.
The target file is DEINFO_SEGTOS_212.shp. It comes originally with a coordinate reference system that seems to be wrong. A better alignment can be reached by using following proj4 parameters:
+proj=utm +zone=23 +south +ellps=aust_SA +towgs84=-86.35,3.88,-38.22,0,0,0,0 +units=m +no_defs
We are working on finding a way to generate address ranges from the shapefile.
Next steps:
- Document a way to import the data to PostGIS
- Develop a scrip to generate address interpolation ways
