projectedPointsForMissionWithName

Project mission ground-track points into a local Transverse Mercator box.

---

Declaration

 alongtrack = projectedPointsForMissionWithName(missionName,requiredOptions,options)

Parameters

• missionName string — mission key
• requiredOptions.Lx double — box width [m]
• requiredOptions.Ly double — box height [m]
• requiredOptions.lat0 double — box reference latitude [deg]
• requiredOptions.lon0 double — central meridian for projection [deg]
• options.time numeric/datetime vector — times at which to sample the orbit
• options.origin {‘lower-left’,’center’} (default ‘lower-left’) — coordinate origin convention for returned (x,y)

Discussion

Computes the ground track for the requested mission within a bounding box centered at (lon0,lat0) with size (Lx,Ly). Points are returned in projected coordinates (using a transverse Mercator projector). By default the origin is set to the lower-left of the bounding box, but can be optionally set to the center.

The function returns a struct with fields (x,y,t) - x: double column vector — projected x-coordinates - y: double column vector — projected y-coordinates - t: column vector — times corresponding to each point (sorted)

                - Returns: alongtrack struct with field (x,y,t)
