# Fantasy GIS Cadastral

## Dependency
Read and follow `../faerun-map-geometry-master/SKILL.md` or the same master instructions included in the project. **Source geography overrides style examples.**

## Style target
Orthographic survey-like plan with precise footprints, parcels, roads, land-use colors, grid, legend.

## Visual recipe
Flat building silhouettes, pale land-use fills, fine parcel boundaries, numbered landmarks.

## Geographic constraints
No invented parcel boundaries; no roof perspective.
Maintain all verified source features and named landmarks at their source coordinates; preserve street network, bridge crossings, water boundaries, building placements, and orientation. Do not import geography from the style reference.

## Conversion procedure
1. Identify the geographic source map and style reference separately.
2. Extract the source's stable geometry manifest and landmark index.
3. Apply this style only to strokes, colors, roof textures, shading, vegetation symbols, typography, and presentation.
4. Maintain source aspect ratio, north direction, and framing unless explicitly requested otherwise.
5. Cross-check every landmark against the source. Fix discrepancies before finalizing.
6. State when result is an approximate image conversion rather than a coordinate-verified render.

## Reusable prompt
> Convert the attached **SOURCE MAP** into **Fantasy GIS Cadastral**. Use the separate **STYLE REFERENCE** for appearance only. Preserve the source map's north orientation, road intersections, building positions and footprints, walls, gates, bridges, watercourses, terrain features, named landmarks and numbered points of interest. Do not add or relocate geographic features. Flat building silhouettes, pale land-use fills, fine parcel boundaries, numbered landmarks. No invented parcel boundaries; no roof perspective. Keep source aspect ratio and extent. If source geometry is uncertain, retain the visible geometry rather than inventing it. No unsupported labels.
