For the last 2-3 weeks I have been back and forth between Hexagon and ESRI's local distributor in Puerto Rico to solve a problem. To date, however I have precious time and don't see a solution in the horizon. This was my workflow:
1) I used GIS online services from NOAA (https://storms.ngs.noaa.gov/storms/maria/index.html#7/18.056/-64.824) to georeference an image in ArcMap.
2) In ArcMap I exported the file to produce an .img. In ArcMap the Current Coordinate System reads (WGS_1984_Web_Mercator_Auxiliary_Sphere;
WKID: 3857 Authority: EPSG; Projection: Mercator_Auxiliary_Sphere: False_Easting: 0.0, False_Northing: 0.0, Central_Meridian: 0.0, Standard_Parallel_1: 0.0, Auxiliary_Sphere_Type: 0.0, Linear Unit: Meter (1.0).
