This app demonstrates how to use calculation fields to display survey locations in GIS projections typically used by our Australian users. 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. The original version referenced in the blog article can be found on the [Custom GIS Projections App page](https://www.fulcrumapp.com/apps/custom-gis-projections-app/).
Some of the projections included:
* EPSG:4326 WGS 84
* EPSG:3857 Spherical Mercator
* EPSG:3111: GDA94 / Vicgrid94
* EPSG:3107: GDA94 / SA Lambert
* EPSG:3112: GDA94 / Geoscience Australia Lambert
* EPSG:3113: GDA94 / BCSG02
* EPSG:3308: GDA94 / NSW Lambert
* EPSG:3577: GDA94 / Australian Albers
