#4159: ST_Distance failing with a geography and a point with specific values
-------------------------+--------------------------------
Reporter: GustavoAcid | Owner: pramsey
Type: defect | Status: new
Priority: medium | Milestone: PostGIS PostgreSQL
Component: postgis | Version: 2.2.x
Keywords: ST_Distance |
-------------------------+--------------------------------
In our project we are loading geographies from different countries from
shapefiles to Postgis (using shp2pgsql) and later querying if specific
points are within some distance from said geographies.
The problem arose when we made the query if this specific coordenates
{{{(-3.6765233, 40.5036783)}}} are inside the Spanish territory (shapefile
used attached). The point is in the center of Madrid, but ST_Distance
between the geography and the points gives {{{242445.14066125}}} as
result.
Query Used
{{{
#!sql
SELECT ST_Distance(regions.area, ST_SetSRID(ST_Point(-3.6765233,
40.5036783), 4326)::geography) as result
FROM regions
WHERE id = 1;
}}}
