All contains all known DCS terrains with their Transverse Mercator projection parameters. Parameters are sourced from pydcs (https://github.com/pydcs/dcs) and dcs-web-editor-mono (https://github.com/DCS-Web-Editor/dcs-web-editor-mono).

Types ¶
type Terrain ¶
type Terrain struct {
// Name is the terrain identifier.
Name string
// CentralMeridian is the longitude of the projection's central meridian in degrees.
CentralMeridian float64
// FalseEasting is added to all X coordinates in meters.
FalseEasting float64
// FalseNorthing is added to all Y coordinates in meters.
FalseNorthing float64
}
Terrain represents a DCS World terrain/map with its Transverse Mercator projection parameters.
func Closest ¶
Closest returns the terrain whose center is closest to the given point. This is used to determine which Transverse Mercator projection to use when the terrain is not explicitly known (e.g., when Tacview doesn't export MapId).
func (Terrain) Center ¶
Center returns the approximate geographic center of the terrain. This is derived from the central meridian and false northing to provide a representative point for the terrain. Useful for terrain selection.
func (Terrain) Projection ¶
func (t Terrain) Projection() *projections.TransverseMercator
Projection returns a Transverse Mercator projection configured for this terrain.
