Convert Lat/Longs to Blob/Shape-thing

[EricThomas3]

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?

Thank you

Example:

Convert FROM

35.649783386

Thanks for the continued guidance. 

Reading through the docs provided, I'm still unclear on how I would POST Lat/Long pairs as "...one of the common spatial data interchange formats to the DBMS geometry constructor". 

Example:

• The DB2 database has a REST web service that I can POST data to
• LocID: 1234
• Lat: 47.123
• Long: -122.345
• etc.

What happens when I get to this ST_Geometry-type column? 

What do I feed it?

Is it a calculated column based on the Lat/Long columns?

If the DB2 database has a REST web service where you can post Lat/Long, and you are working with Points, what is the issue?  The REST service should take the Lat/Long and convert it to the appropriate native spatial type on the backend.
