Coordinate Reference System Converter

A utility that standardizes coordinate reference system (CRS) information from multiple input formats into a common output format.

Capabilities

Parse CRS from EPSG code

• When given the integer 4326, returns a dictionary with CRS information in PROJ JSON format @test
• When given the integer 3857, returns a dictionary with CRS information in PROJ JSON format @test

Parse CRS from PROJ string

• When given the PROJ string "+proj=longlat +datum=WGS84 +no_defs", returns a dictionary with CRS information in PROJ JSON format @test
• When given the PROJ string "+proj=merc +a=6378137 +b=6378137", returns a dictionary with CRS information in PROJ JSON format @test

Parse CRS from WKT string

• When given a WKT string for WGS84, returns a dictionary with CRS information in PROJ JSON format @test

Convert CRS to WKT format

• When given an EPSG code 4326, returns the Well-Known Text representation of the CRS @test
• When given a PROJ string "+proj=longlat +datum=WGS84 +no_defs", returns the Well-Known Text representation of the CRS @test
