Background
Natural and Artificial Land Covers The Earth is blanketed by hundreds of different types of land cover. There are the natural covers, such as forests, open waters, and woody wetlands. Artificial land covers include the roads, homes, parking lots, and offices of cities and towns. There are also natural land covers that have been created or shaped by humans, such as pasture and cultivated croplands. Land cover is any growth or structure that covers the non-ocean portions of Earth’s surface. In the United States, there are 16 different categories of land covers tracked by the U.S. Geological Survey (USGS) using the Land Coverage Analysis Tool (LCAT).
Land Cover and Land Use We track land cover because land cover affects us. Each type of land cover is best suited for a few purposes. To build homes, we usually seek cleared land near paved roads. To grow food, we often need to plow. To generate power, we mine or drill into some lands and build power plants on others. Transportation requires a highway, a waterway, or a railroad. Land cover is inextricably linked to land use. The LCAT helps people form environmentally and economically sound plans for land use and development.

Procedure
Materials Computer with Internet access
Step 1To find a map of land cover in your area, go to the USGS Land Cover Analysis Tool (LCAT) and activate the LCAT.
Step 2Select the “Analysis Layer” from the tab at the upper right of the screen. Make sure you select the most recent USGS Land Cover Data Set. Notice that different types of land cover are denoted by different colors.
Step 3In the upper right corner of the map, enter your street address and click Go.
Step 4Adjust “Analysis Layer Transparency,” so that you are able to see map features, such as towns and street names, underneath the colors of the map.
Step 5Zoom in so you can find the location of your home—or as close as you can go. If you have trouble finding your home’s location on the map, zoom in to whichever location near your address—a street, school, cemetery—is identifiable on the map, and navigate from there. Note that the land coverage data change as you zoom in or out on the map.
Step 6Complete the Data Tables for types and percentages of land cover.
Find the following information about land cover in your neighborhood.
2.Download, print, and attach a PDF report of the land cover in your neighborhood. Fill in the table below. Use a separate sheet if necessary.

4.Zoom out to view your whole city or town and the surrounding area—your region. In the data table below, list the three most common land-cover types. Then, download and print a PDF report that lists all the land-cover types, amount of area covered, and the and their percent of coverage for that land cover in your region. Copy this information into the table. Use a separate sheet of paper if necessary.
