Base maps: Out With the Old, In With the New (2 min)

It has been almost a decade since UGRC has updated the look and feel of any of the base maps but changes are on the way! The current suite of base maps were originally authored in ArcMap. These projec

How To Use UGRC Base Maps in QGIS (1 min)

Most people know about UGRC's awesome base maps. They are very popular and provide high quality cartography using the latest and greatest data from the Utah SGID. But did you know that they provide a

Using Base Maps with Non-standard Coordinate Systems in LeafletJS (2 min)

Since LeafletJS [https://leafletjs.com/] seems to be what all of the cool kids are using these days and it shows no signs of slowing down [https://www.mapbox.com/blog/vladimir-agafonkin-joins-mapbox/], I thought that it would be fun to figure out how to use Leaflet to view UGRC's awesome base map services [/products/sgid/base-maps/].

First I create a new Proj4Leaflet coordinate reference system which I pass into the map constructor. Then I use the Esri-Leaflet Plugin to set up a new TiledMapLayer and add it to the map. Now you can be one of the cool kids too!
