GeoBoundsRegion
GeoBoundsRegion[{{latmin,latmax},{lonmin,lonmax}}]
is a two-dimensional GeoGraphics primitive that represents a geo region bounded by parallels latmin, latmax and meridians lonmin, lonmax on the surface of the Earth.
represents the latitude-longitude bounding box of the geo region g.
GeoBoundsRegion[g,δ]
pads the ranges of latitudes and longitudes by ±δ.
Details
- Latitudes and longitudes can be given as numbers in degrees or as Quantity angles.
- The geo bounds region is taken to cover longitudes from lonmin toward the east until reaching lonmax.
- GeoBoundsRegion[g,δ] for a geo region g and a padding specification δ is equivalent to GeoBoundsRegion[GeoBounds[g,δ]].

Scope (3)
Provide latitudes and longitudes as numbers in degrees:
Provide latitudes and longitudes as Quantity angles:
Or using a QuantityArray object with angular unit:
Draw the bounding box of a geo region:
Use a cylindrical projection, like Mercator, to get a rectangular shape:
Properties & Relations (6)
The range {lonmin,lonmax} of longitudes is taken to have lonmax to the east of lonmin:
GeoBoundsRegion[g] is equivalent to GeoBoundsRegion[GeoBounds[g]] for a geo region g:
The boundary of a GeoBoundsRegion primitive is given by GeoBoundsRegionBoundary:
Sides of a geo bounds region are parallels and meridians, not geodesics:
The sides of the geo bounds region are rhumb lines:
The shape of a geo bounds region depends on the projection being used:
A geo bounds region reaching latitude 90 or -90 is actually a sector of a geo disk centered at that pole:
Possible Issues (1)
These two maps coincide, even though the locations are reversed:
This is because GeoBounds is insensitive to orientation:
To get the complementary rectangle in longitudes, use the following:
