This package should be expanded to support data processing, using a language that can perform the following:

• Geo operations:

  • Project geometry
  • Simplify geometry
  • Extract centroid
  • Compute area
  • Compute perimeter
  • Compute bounding box
  • Compute pluscode

• Property operations:

  • Delete property
  • Filter by property
  • Set property
  • bool(...)
  • int(...)
  • float(...)
  • str(...)
  • lower(...)
  • upper(...)
  • strip(...)
  • substr(...)
  • replace(...)
  • abs(...)
  • sqrt(...)
  • round(...)
  • ceil(...)
  • floor(...)
  • m2ft(...)
  • ft2m(...)
  • sqm2sqft(...)
  • sqft2sqm(...)

The language should also support:

• Conditional statements
• Variable assignment
• Basic arithmetic (addition, subtraction, multiplication, division)
• Comparisons (less than, greater than, equal to, not equal to)
• Logical operators (and, or)

Right now, we simply write out all data to standard out, which allows a shell-based process to redirect the standard out to a file or some other downstream process.

It would be convenient to optionally allow an output file to be specified, so that the proper output encoding can be used automatically.

We currently support GeoJSON files, SHP files, and SHP archives. It would be useful to include KML files, since a lot of geodata comes in that format.

We can maybe use the input and output file extensions to automatically decompress/compress incoming and outgoing data files.
