Definition Meaning
STATE State Abbreviation
ESCALING Linear or Square Root (sqrt) elevation scaling.
EXTRUDER Dual or Single color (extrusion) model
STYLE* (optional) Model special style or subregion. STYLE is only present when the model file is a special style or the model is exclusive to a special subregion.
REVISION Revision number. See release notes for the latest improvements.
PIECE##(optional) Interlocking pre-cut piece ## sized for 180 mm x 180 mm bed.

*Default STYLE is water features model located over submerged low lying lands. This submerged land may be visible when water layers are printed with a transparent filament. Default style minimizes usage of secondary (water) filament color. transparent style has water model features that extend all the way through the land for maximum light transmission when used with glow and transparent filaments.

If multi-part files are not present, I have not created interlocking models for this state yet. Follow me and comment with your request to get future additions and updates.

Map Specification Value Notes
Projection USA Contiguous Lambert Conformal Conic  
Projection (Alaska) NA Lambert Conformal Conic  
Projection (Hawaii) UTM zone 4N  
Horizonal Scale 1:2500000 (0.4mm:1000m) Effective resolution is 1000m x 1000m.
Horizontal Scale (Alaska) 1:2500000 (0.4mm:1000m) Effective resolution is 2000m x 2000m.
Vertical Scale (Linear) 1:500000 (0.1mm:50m) Vertical exaggeration is 5x. Elevations 0-40m are scaled between 0 and 0.8mm on a logarithmic scale for enhanced coastal detail.
Vertical Scale (Square Root) 1:500000 (0.1mm:50m) Vertical exaggeration is greater at lower elevation and lower at higher elevation, ranging from 285-5x between sea level and ~4000m. Linear and Square Root elevation breakover at ~4000m.
3D Model Resolution 0.1mm  
3D Model Resolution (Alaska) 0.2mm  
Highlights Streams, Lakes, Coastlines  
Maritime Boundary Submerged Lands Act Seaward boundary of coastal states generally 3 or 9 nm from the coastline. Maritime boundaries are included in the dual print models.
Model Base Thickness at Sea Level ~0.9mm Additional +0.9mm (dual) / +0.4mm (single) for locations not covered by water.

China

China model is at same scale as USA except for the following. Streams and base thickness are 4x thicker so that model can be more easily printed at 25% scale.
