twc-express-lambda

If you have an API key for The Weather Company, you can use this nodejs express based server in the ArcGIS Online Webmap viewer and other apps.

Test it out

• git clone
• npm install
• npm start

To get a listing of available layerIds, you can use this call:

http://localhost:8080/layers?apiKey=12345678910

You can add a URL to ArcGIS Online as a Tile Layer. You will need to subsititute the layerId for the layer you wish to use as well as provide your own apiKey. Leave the level, row, and col params formatted with curly braces.

Example:

http://localhost:8080/<layerId>/{level}/{row}/{col}/<apiKey>
