Chapter 13: Working with Location Information > Understanding Location Basics

Understanding Location Basics

Before you start looking at the mapping capabilities of Android and Mono for Android, here are some mapping terms that are used throughout this chapter:

  • Latitude: The Y value of a location (90 to -90 degrees north to south).
  • Longitude: The X value of a location (180 to -180 degrees east to west).
  • Heading: Compass direction expressed in degrees (0 to 360).
  • GPS: Global Positioning System. A collection of satellites using radio signals to enable Earth-based receivers to determine their location with a high degree of accuracy.
  • Geocoding: Resolving a search string (such as an address, business, or landmark name) to a geographic location (latitude/longitude).
  • Reverse geocoding: Finding the “human-readable” address for a specific latitude/longitude location.
