What I Look For
Each city is judged as a complete flying area. I look at the quality of the photogrammetry, the shape and texture of buildings, how roads and rivers behave, how wide the coverage is, and whether there are enough interesting places to make the city worth exploring.
Visual Fidelity
Crisp textures, believable buildings and clean geometry score higher than soft, melted or badly warped areas.
Infrastructure
Roads, rivers, bridges, ports and railways should look clean and structural rather than blocky, broken or distorted.
Coverage Area
A wider, more complete PG area with good blending into the surrounding scenery usually gives better exploration value.
Points of Interest
Diverse places such as downtown areas, stadiums, bridges, ports, industrial estates, coastlines and accurate airfields all help.
