# Fantasy Land Cover Map

## When to use
Forest, grassland, cropland, marsh, scrub, rock and water. Use when asked to produce, restyle, compare, or extract this type of fantasy map, especially in Faerûn.

## Inputs
- A user-designated authoritative base map or authoritative geometry/layers (required for factual maps).
- Optional official secondary maps, annotations, historical dates, relevant records, and requested projection or crop.
- Optional visual-style references; do not use illustrations as geographic truth.

## Style and production rules
Make a categorical land-cover map with a single flat, distinct color per supported cover class; optional texture must not hide category boundaries. Classify only land-cover evidence, not elevation. Legend entries may include dense woodland, sparse woodland, grassland, farmland, marsh, scrubland, bare rock, sand and water as supported by source.

## Special validation rules
- Maintain original class boundaries and unknown/unmapped spaces.
- Do not mistake topographic shading for forest or desert.
- Do not invent land use within blank spaces or settlements.
- Keep river, coast and wetland polygons separate as source indicates.

## Source integrity contract (required for every output)
1. Identify and rank the supplied authoritative sources before drawing. Latest user-designated official/source map controls the crop, feature positions and route geometry. Secondary maps may clarify names and dates, not silently replace geometry.
2. Keep the **exact region, area, or floor extent** shown by the user; do not fill outside the map. Treat blank/unknown as unknown, not as permission to invent.
3. Trace rivers, tributaries, coastlines, roads, paths, trails, tracks, crossings and junctions **only where source material supports them**. Preserve endpoints, turns, classifications and non-connections. Never invent a connecting line.
4. Reuse source-supported settlements, landforms, walls, gates, bridges, ruins and other sites in their proper positions. A named bridge or road junction is not automatically a town.
5. Separate mapped facts from inferred/schematic items. If a date, height, border, route, ownership or terrain class cannot be verified, show it as unknown or omit it. Do not fabricate scales, units, intervals or coordinates.
6. If multiple reference maps conflict, stop and flag important conflicts rather than averaging their shapes. Make a feature inventory and comparison checklist before rendering.
7. After drawing, visually compare the final map with source(s): same extent, topology, features, labels and spelling. Fix extra/missing/moved elements. Treat earlier AI-made maps only as **style references**, never geographic evidence.

## Shared map data / skill compatibility
May take a GIS map, georeferenced drawing, linework, vector layers, annotated raster, or plain reference image from the user's Fantasy GIS Cadastral Map, Fantasy Map to GIS Converter, Fantasy Topographic Survey, Illustrated Town Atlas, Regional Area Map or scenic skills. Keep a clean reusable set of source-controlled layers (water, relief, vegetation, routes, settlements, labels) where available. Do not assume missing layers exist.

## Handoff / delivery
Provide the finished requested visual or structured map file when feasible, plus a short list of **sources used**, **estimated/unknown details**, and **checks performed**. Do not label a decorative drawing GIS-accurate or measured without valid underlying data.


## Output quality checklist
- [ ] Style fits **Fantasy Land Cover Map**.
- [ ] Exact same extent as source.
- [ ] All provided relevant features and names retained and correctly spelled.
- [ ] No invented road, path, river, bridge, settlement, border or site.
- [ ] Numeric measurements and periods supported by input or clearly marked unknown.
- [ ] Geometry and route connections compared against base reference.
- [ ] Map symbols, line types and legend are clear and consistent.
