I have a database stored in WGS84 EPSG:4326
I would like ti find objects within a distance from a lat/lon point.
1) If i use 1 degree as the distance, will I then get an eliptic search area?
2) Will i find objects on the other side of the Datum shift border if I enter a point like lat=60°, lon= -179,5° with a distance of 1°?
3) Hov do I enter a lat/lon point and a distance in meters?
