We have data on in our hub that was uploaded in FL State Plane East Ft projection. I know that when you use the map on AGOL that it is Mercator in Lat Long. When downloading the data as a csv, the polyline length is not matching up to the length in our data with any conversion of types. I need to be able to tell someone that has downloaded this data what the length of the polyline represents, but it's difficult when the length of the line is 285.334 ft, translates to 0.0869 km and the length in the csv file is 0.0008124.
If anyone can point me in the right direction for the projection that would be great.
