Module wm 

All WM tooling

Structs

ConvertedGeometry

The resultant geometry after conversion

ConvertedLineString

LineString converted from WM to S2

Enums

Rotation

Track the rotation of a face

Source

The source of the coordinate inputs

Constants

A

900913 (Web Mercator) constant

FACE_RULE_SET

Ruleset for converting an S2Point from a face to another. While this this set includes opposite side faces, without axis mirroring, it is not technically accurate and shouldn’t be used. Instead, data should let two points travel further than a full face width. FACE_RULE_SET[target_face][currentFace] = [rot, x, y]

MAXEXTENT

900913 (Web Mercator) max extent

MAXLAT

900913 (Web Mercator) maximum latitude

Traits

ConvertFeature

Underlying conversion mechanic to move GeoJSON Feature to GeoJSON Vector Feature

ConvertVectorFeatureWM

Underlying conversion mechanic to move GeoJSON Geometry to S2 Geometry

Functions

altitude_from_mercator_z

Convert mercator projection’s Z-Value to altitude returns the altitude

altitude_to_mercator_z

Convert altitude to mercator projection Z-Value returns the Z-Value

bbox_to_xyz_bounds

Convert a bbox of the form [w, s, e, n] to a tile’s bounding box in the form of { minX, maxX, minY, maxY } The bbox can be in lon-lat (WGS84) or WebMercator (900913) The default expectation is in WebMercator (900913) returns the tile’s bounding box

circumference_at_latitude

The circumference at a line of latitude in meters.

convert_bbox

Convert a bbox of the form [w, s, e, n] to a bbox of the form [w, s, e, n] The result can be in lon-lat (WGS84) or WebMercator (900913)

convert_geometry_to_vector

Convert a GeoJSON Geometry to an Vector Geometry

convert_geometry_wm_to_s2

Underlying conversion mechanic to move GeoJSON Geometry to S2Geometry

convert_vector_to_geometry
