Solution

It can be considered as a map following points prove it:

There are two types of maps used in photogrammetry

Planimetric maps – Planimetric maps are maps that represents only the horizontal features of the mapped area. Planimetric maps display features such as roads, sidewalks, buildings, river banks, shore lines, manholes, trees etc.

Topographic maps – Topographic maps are maps on which both horizontal and vertical features of the mapped are represented .

The output of photogrammetry is typically a map, drawing, measurement, or a 3D model of some real-world object or scene. Many of the maps we use today are created with photogrammetry and photographs taken from aircraft.
