EPSGlide 0.1.0

Efficient great circle computation and projection library with access to EPSG dataset public API

Python epsglide package

This package aims to perform simple requests to EPSG Registry API and provides associated geodesic computation and map projection.

EPSG dataset requests and projection

>>> import math, epsglide
>>> crs = epsglide.ProjectedCoordRefSystem(26730)
>>> crs
<ProjectedCoordRefSystem #26730: NAD27 / Alabama West>
>>> point = epsglide.Geodesic(math.degrees(crs.lambda0), math.degrees(crs.phi0))
>>> crs(point)
<US survey foot:3.281[X=152400.305 Y=0.000] alt=0.000>
>>> crs(crs(point))
<lon=-087°18'0.00000" lat=+030°00'0.00000" alt=0.0>

Great circle computation

>>> wgs84 = epsglide.dataset.Ellipsoid(7030)
>>> dublin = epsglide.Geodesic(-6.272877, 53.344606, 105.)
>>> london = epsglide.Geodesic(-0.127005, 51.518602, 0.)
>>> dist = wgs84.distance(dublin, london) 
>>> dist
<464.572km initial bearing=113.5° final bearing118.3°>
>>> wgs84.destination(dublin, dist) 
<lon=-000°07'37.21798" lat=+051°31'6.96719" end bearing=118.3°>
>>> london
<lon=-000°07'37.21800" lat=+051°31'6.96720" alt=0.0>
