Elevation, terrain, and 3D

Generated from the same registry as the Chinese reference. Contract version: 0.5-session. Edit the registry and reviewed English catalog, then rerun script_contract; do not edit this file. See the script guide.

Platform labels below are registry declarations, not device acceptance. Consult the platform coverage guide for actual host coverage and limits. These are the existing gis compatibility-module APIs; the shared sqsmap map facade is documented separately.

map

`map.setTerrain`

Enable a real Mercator surface from a common raster-dem, exaggeration 0..20, or disable with null. Desktop local DEM retains its state-return differences.

Permission: map.write
Declared platforms: desktop, mobile, web
Signature: map.setTerrain(arg0: TerrainSpecification | null): Operation<TerrainState | TerrainSpecification | null>

`map.getTerrain`

Read common source/exaggeration options or desktop local DEM status. Disabled returns null; common readiness comes from getSourceInfo.

Permission: project.read
Declared platforms: desktop, mobile, web
Signature: map.getTerrain(): Operation<TerrainState | TerrainSpecification | null>

`map.queryTerrainElevation`

Common terrain returns a bilinear loaded DEM height in meters multiplied by exaggeration, or null. Desktop local DEM retains the TerrainElevation object with raw height and datum.

Permission: project.read
Declared platforms: desktop, mobile, web
Signature: map.queryTerrainElevation(arg0: [number,number]): Operation<number | TerrainElevation | null>

`map.setProjection`

Switch projection with a type object: geographic, mercator, or globe. Change desktop GIS display coordinate systems through the dedicated desktop interface.

Permission: map.write
Declared platforms: desktop, mobile, web
Signature: map.setProjection(arg0: ProjectionSpecification): Operation<ProjectionSpecification>

`map.getProjection`

Read the current view projection.

Permission: project.read
Declared platforms: desktop, mobile, web
Signature: map.getProjection(): Operation<ProjectionSpecification>

gis.pointClouds

`gis.pointClouds.neighbors`

Find nearest points in an entire local point cloud using WGS84 center and meter radius; return at most 100 samples.

Permission: analysis.execute
Declared platforms: desktop, mobile
Signature: pointClouds.neighbors(arg0: SourceRef | string, arg1: PointNeighborOptions): Operation<PointNeighbors>

`gis.pointClouds.toDem`

Create a temporary DEM from an entire local UTM point cloud, optionally using estimated ground points only.

Permission: analysis.execute
Declared platforms: desktop, mobile
Signature: pointClouds.toDem(arg0: SourceRef | string, arg1: PointDemOptions): Operation<RasterRef>

`gis.pointClouds.density`

Create temporary point-density raster data in points per cell from an entire local UTM point cloud.

Permission: analysis.execute
Declared platforms: desktop, mobile
Signature: pointClouds.density(arg0: SourceRef | string, arg1: PointDensityOptions): Operation<RasterRef>

`gis.pointClouds.classifyGround`

Apply progressive morphological ground classification to an entire local UTM point cloud, returning a temporary table without changing the source.

Permission: analysis.execute
Declared platforms: desktop, mobile
Signature: pointClouds.classifyGround(arg0: SourceRef | string, arg1: GroundClassificationOptions): Operation<ClassificationRef>

map.workspace

`map.workspace.save`

Preview a JSON manifest of the 3D workspace, including terrain, point clouds, model/tiles, splats, and camera; applying requires host confirmation.

Permission: export.write
Declared platforms: desktop, mobile
Signature: map.workspace.save(arg0: FileExportOptions): ChangePlan<FileRef>

`map.workspace.load`

Preview restoring a JSON 3D workspace manifest. append adds resources; replace first removes existing 3D content. Confirm before restoring the batch.

Permission: map.write
Declared platforms: desktop, mobile
Signature: map.workspace.load(arg0: string, arg1?: WorkspaceLoadOptions): ChangePlan<WorkspaceRestoreResult>
