How can I get the Polygon data for a location name?

Question

I'm looking for a valid source, from where I can get the polygon coordinates for a location. Is there any API for this?

Does Google maps API provide this polygon coordinates? What are the other options for this process? For example, I want to get the Las vegas polygon as

          bounding_polygon_coordinates=[
            [
              [
                -105.549276,
                35.774311
              ],
              [
                -105.523848,
                35.766057
              ],
              [
                -105.526546,
                35.736796
              ],
              [
                -105.476596,
                35.7116
              ],
              [
                -105.461345,
                35.714209
              ],
              [

Answer 1

Before answering this question, it's important to identify the way to view how things should get viewed.

A point is a point. A point has no volume, no distance, no circumference, and no area. A point can be a simple thing having only two dimensions - an X and Y value. Otherwise called coordinates.

A line is just a bunch of points that are connected together. A line is similar to a point. The line has no volume, no circumference, and no area. A line never goes around and crosses itself. But a line does have length. But that length might not always be the same. The length of a line might be different because the length is based on how the line gets measured.

A polygon is just a bunch of points and lines that go around until the last point connects to the first point. A polygon has volume, has circumference, and has some measurable volume.

To be able to answer this question: " I'm looking for a valid source, from where I can get the polygon coordinates for a location. Is there any API for this? ", requires knowing what the location is. What is the location? Is the location the coordinate from a GPS or is the location a bunch of points and lines that are used to make the boundaries of a park or an entire state?

Only after the identity of an object (point, line or polygon) is first identified and determined does the question, " where I can get the polygon coordinates for a location" make any sense. And only after that geo-object is identified does it then become a question in determining which geodata source, which software package (sf, sp, spdep, raster, etc... ), or which geo-application (Google etc... ) to use become a real question having any significance.
