The data is distributed under theEtalab Open Licence 2. ![]() The distance between a polygon and a POI > from geodist import GeoDist The azimuthal equidistant projection is a map projection where all points on the map are at proportionally correct distances from the center. Then, we project the geometric object from the World Geodetic System (aka: WGS84) to the World Azimuthal Equidistant Projection (aka: ESRI:54032) with our POI as the center point of the projection. Using geodist with Longitudes and Latitudes Stored In a Variable The Vincenty (1975) and Haversine formulas produce fairly similar measures of distance. Finds the distance between a POI (point of interest) and a geometric shape on Earth's surface Objectiveįind the distance between a point of interest and a geometric shape – polygon, circle, line string and a Point on earth’s surface using latitude and longitude associated with the geographic coordinate system Install pip install geodistįirst, we convert an array of points (lng, lat) to a planar geometric object.
