I'm trying to POST lat/longs to a database that feeds Portal. My GIS guy says I need to convert the lat/longs to a "Blob/Shape" as shown below.
1. What is this Blob/Shape-thing?
2. How do I programmatically convert Latitude and Longitudes to this Blob/Shape-thing WITHOUT using ArcGIS desktop or Python?
Is there an API / service somewhere that does this?
