Connecting to geodata.no to get additional info from coordinate data

Geodata-Connector

This is a repo for connecting to geodata.no

This repo allows you to send a wkid and x and y coordinates from SESAM and then in return get kommunenr, gårdsnr og bruksnr on the /geo_data route.

Routes:

/geo_data

/fylke

How to:

Run program in development

This repo uses the file package.json and yarn to run the required commands.

1. Make sure you have installed yarn.
2. Creata a file called helpers.json and set username, password and referrer in the following format:

{
    "username": "some username",
    "password": "some password",
    "referrer": "referrer url",
    "fylke_id": "some int",
    "attributes": "kommunenr,gardsnr,bruksnr,festenr",
    "base_url": "https://services.geodataonline.no/arcgis"
}

3. run:

       yarn install
   

4. execute to run the script:

       yarn swagger
   

Expected payload on the /geo_data route:

 [{ "payload": [{
 "wkid": "3857",
    "x_coordinate": "~f924159.9248",
    "y_coordinate": "~f8025279.145"	
 },{
 	"wkid": "3857",
    "x_coordinate": "~f933165.1418",
    "y_coordinate": "~f8020815.2854"
 }]
}]
