LambertIIConversion is a quick example of geographical conversion with Proj4Js using NodeJs. It converts the position of an antenna (x and y fields in siteCoord.csv) from the Lambert II coordinates system into Latitude/Longitude.
- NodeJs
- Run
npm install
to retrieve libraries used such as node-proj4js. - Move the file EPSG27572.js in
node_modules/proj4js/lib/defs
to enable conversion from or to Lambert II. - Since the node_modules directory is provided, the two steps above shouldn't be necessary.
- Run the program with
node conversion.js
.
The program will output all data in a file named newCoord.csv. This file should be initialized with "c";"name";"l";"lat";"lon";"X";"Y";"s". You can see an example of a proper initialized file in newCoord_example.csv. The generated csv will have two more fields: Latitude and Longitude. You can find an already generated file named newCoord_complete.csv.
