Coordinate Converter

Coordinate Converter is used to convert coordinates from a JSON http response. Specfically, this program is used at OSU with ARCGIS to convert coordinates to latitude and longitude.

Coordinate System

This program is meant to convert coordinates for locations at Oregon State University. As such, the coordinate projections we are accepting are either:

NAD_1983_HARN_StatePlane_Oregon_North_FIPS_3601_Feet_Intl WKID: 2913 Authority: EPSG

or

WGS_1984_Web_Mercator_Auxiliary_Sphere WKID: 3857 Authority: EPSG

Accepting both coordinate types is a temporary feature that will soon be deprecated after all coordinates given from ARCGIS are NAD_1983 (WKID 2913).

All coordinates are converted to the WGS84 projection.

Usage

Run It Locally

This program requires CS2CS and Golang to run locally.

go install
# URL of ARCGIS Json endpoint. Required
URL="www.example.com/arcgisjsonendpoint"

# Path to json output file. If no file path is provided, path will be $PWD/converted-coordinates.json
FILEPATH="/path/to/desired/output.json"
coordinate-converter -u "$URL" [-f "$FILEPATH"]

Run It in Docker

Included is a docker-compose file that starts containers for CS2CS and Golang to build the executable. A file called converted-coordinates.json will be created in $PWD when running this command:

export URL='www.example.com/arcgisjsonendpoint'
docker-compose up --build
