What is the method for determining whether a latitude-longitude coordinate is part of a Geometry?

edit

The method for determining whether a latitude-longitude coordinate is part of a Geometry includes the following steps:

1. Convert the latitude-longitude coordinate into a point geometry using a suitable GIS software or application.

2. Compare the point geometry with the existing geometries of the dataset or feature class.

3. If the point geometry coincides with any existing geometry, the coordinate is part of the geometry.

4. If the point geometry does not coincide with any existing geometry, it is not part of any geometry in the dataset.

Alternatively, some GIS software and applications also provide a 'Spatial Query' tool to check whether a point falls within a specific area or geometry.
