 ## Overview of inserting geospatial data into a hyper file
 
-The basic process for adding geospatial data involves defining your inputs to Hyper APIs inserter and specifying how to convert the text strings to the `tableau.tabgeography` type using Hyper SQL expressions. Hyper APIs inserter pushes the expression down to Hyper to convert text string to geospatial data on the fly during insertion.

Hyper APIs inserter pushes the expression down to Hyper to convert a text string to geospatial data on the fly during insertion.
 
 When you add the text strings into the Hyper file, the text must be in the Well-known text (WKT) format for geospatial data. The WKT format is defined by the Open GIS Consortium, Inc, in the [*OpenGIS Simple Features Specification For SQL*](https://www.opengeospatial.org/standards/sfa). The types include **Point**, **MultiPoint**, **LineString**, **MultiLineString**, **Polygon**, and **MultiPolygon**.
