GIS Projections App

An app to demonstrate embedding proj4js in calculation fields to display record locations in custom GIS projections.

This app demonstrates how to use calculation fields to display survey locations in any GIS projection. Check out the [GIS projections blog post](https://www.fulcrumapp.com/blog/custom-projections-in-calculation-fields/) to find out more about how it works. The app uses the [proj4js](http://proj4js.org/) JavaScript library to re-project the coordinates of the record location to multiple different projections. In the demo, it shows: * EPSG:4326 WGS 84 * EPSG:3086 NAD83 / Florida GDL Albers * EPSG:3857 Spherical Mercator * EPSG:3031 Antarctic Polar Stereographic * EPSG:26917 UTM zone 17N

Reports are fresh and provide more detailed information. I don't miss any reports like I did in the past and I don't have to chase people down later.

Our field technicians are spending less and less time in the office. They spend it more on field tasks, rather than office tasks.
