Make sure the working directory of your Stata file is the same as the working directory of the data file. The distance between a Linestring 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, using the geocoding command geodist in STATA, we used the number of apprehensions processed through the nearest ERO office to a student's home zip. 28 Effect sizes were calculated using genatmedian. 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. 27 Distance is as the crow flies (great-circle) and is calculated using the Stata program, geodist.

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.
