projpicker 0.1.5.post7

ProjPicker (projection picker) allows the user to select all projections whose extent completely contains given points, polylines, polygons, and bounding boxes. The goal is to make it easy and visual to select a desired projection by location.

ProjPicker

ProjPicker (projection picker) is a Python module that allows the user to select all coordinate reference systems (CRSs) whose extent completely contains given points, polylines, polygons, and bounding boxes using set-theoretic logical operators in a postfix notation. The goal is to make it easy and visual to select a desired projection by location. This project was motivated by a GRASS GIS feature request. A new GRASS GIS module g.projpicker that wraps around this project is available. It is a work in progress; join discussions. See also its documentation.

Branches

main

This branch is the main development and release branch for both the API and CLI of ProjPicker.

rtree-oop

The rtree-oop branch utilizes the rtree module in an object-oriented programming (OOP) way. This branch supports point intersection. The rtree spatial indexing may not be able to handle reversed west and east longitudinal boundaries that cross the antimeridian. This branch is archived and not under active development.

TODO

1. GUI
   • ArcGIS Pro Toolbox for ArcGIS users including IESA students
   • Web (client-only)
   • Desktop
2. CRS hints
   • Crowdsourcing agency and product information? Is usage from PROJ enough?

Versioning

N(.N)*[{a|b|rc}N][.postN][.devN]

• PEP 440
• {a|b|rc|.dev}N towards and .postN away from the release
• Not fully compatible with semantic versioning
• Not using build numbers marching away from or towards a release, but check this interesting comment.
