# 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]].

## Basic Examples(2)

A geo bounds region over part of Europe:

Draw the polygon of a country and its bounding box:

## 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:

## Applications(1)

Use different map styles in different latitude-longitude regions:

## Properties & Relations(6)

The range {lonmin,lonmax} of longitudes is taken to have lonmax to the east of lonmin:

is equivalent to 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)

Take two locations:

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:

## Neat Examples(1)

Define the countries and colors to use:

Make a map showing the geo bounding regions of South American countries:
