What is an orthophoto? Coordinate systems, accuracy, and WGS84

Orthophotos are geometrically corrected aerial images that work like a measurable map, letting construction and survey teams check distances, areas, and positions across a site. This guide covers how they’re built from drone photogrammetry, what actually drives their accuracy, and why coordinate systems like WGS84 determine whether your data lines up with design files.
