I am working on a choropleth map for a real estate site. My current workflow is:
- Edit and save SHP file's DBF in Libre Office Calc.
- Load SHP file into Quantum GIS. Set colored breakpoints based on data.
- Load modified SHP file in TileMill (MapBox). Layer it over basic map.
- Push the map to MapBox host.
This whole process is very tedious considering that the choropleth map requires frequent updating.
Now, I am trying to find a more efficient workflow to produce the same result. My intuition is that leveraging Google Maps and Google Spreadsheets may be a better way to go. However, I haven't found a good tutorial that accomplishes my specific needs.
Any advice is greatly appreciated.
