### Geographic Data and Analysis - **Elevation:** The height of a landform above sea level. - **Map projection:** A method of transferring a spherical surface (like Earth) onto a flat map, which inevitably introduces distortions. - **Absolute location:** The exact position of a place on Earth, usually expressed in latitude and longitude coordinates. - **Relative location:** The location of a place in relation to other places. ### Geographic Data and Analysis 1. **Geographic information systems (GIS):** A computer software system that can capture, store, manipulate, analyze, and display geographic data. 2. **Global positioning systems (GPS):** A satellite-based navigation system that can determine a precise location on Earth.
