Description
Low Poly edition of the USA Lower 48 States
In this model all elevations are square root scaled to reduce high elevation outliers and enhance low elevation detail. Find the full resolution USA lower 48 states combined here and print higher resolution individual state topo map models in USA of Plastic collection here.

You can scale the model up or down as needed to fit your printer size, the final map's scale will just be scaled accordingly. E.g. 200% scale on a previous scale of 0.4mm:1000m results in 0.4mm:500m
Pictured print was printed at 0.1mm layer height; model is detailed enough to be printed at higher or lower layer height depending on your preference.

| Cartographic Specification | Value | Notes |
|---|---|---|
| Projection | USA Contiguous Lambert Conformal Conic | |
| Horizonal Scale | 1:25000000 (0.4mm:10000m) | Effective resolution is 500km x 500km (0-2 file) or 1000km x 1000km (0-1 file). |
| Vertical Scale | No linear ratio due to square root scale | Vertical exaggeration is ~3500x. Elevations are scaled on a square root scale to eliminate outliers at high elevation and bring out more detail at low elevation. |
