ArcGIS Elevation Profile - Meters to feet for Elevation Rusults

JasonGibbons1 — Tue, 24 Jan 2017 16:39:46 GMT

I've created a Geoprocessing Service from a DEM based on feet, but can't figure out why my results are being multiplied by, basically, 3.28 (e.g. DEM cell value of 2884.33 feet and elevation profile results in elevation of 9,460 ft. See the code lines below. I downloaded the profile application here: https://www.arcgis.com/home/item.html?id=4aa7e7ae8b964ee88c78cc261b9faf82

If anyone could provide some guidance I would be much appreciated. I'm currently at a loss as to where to change the code as I followed the directions as best I could.

Thanks
