Use this page to make maps of sites and site clusters by time period and/or site/feature type (Site Component). The standard Google Maps controls, on the left side of the map, can be used to pan and zoom, and you can select what kind of map (Road, Terrain or Satellite) from the controls at the top right of the map window. For Road maps, uncheck "Terrain" under "Map"; for Satellite maps, you can turn off the map labels.
You can select the time period and site/feature type from the drop down lists, and then choose what color to use to display individual site points. Then press the "Submit" button; press the "Reset" button to clear your selections from the drop down lists; press the "Clear Map" button to clear any sites and site clusters from the map.
The search results are returned on the map like the example shown here. Site points are small circles with the color you requested. You can hover the map cursor over the site points, and the site name will be displayed. The larger colored "radar screens" are clusters of sites, and the number in the center tells you how many sites are in the cluster; you can click on a cluster and the map will zoom in and display the site points that make up the cluster, or it will show smaller clusters. You may have to zoom in several levels to get to site points in an area where they are densely packed.
If you want to use the map in a PowerPoint or word processing document, copy the whole screen (using Print Screen), or a part of it, paste it into a graphics program, then crop it to the map. This is necessary because there isn't a simple "Copy" function in the Google Maps API -- it's not an image that can be copied. The map is sized to create the maximum-sized vertical map image from a 1280x1024 resolution monitor, but you may need to scroll down slightly to get the entire map in your screen-copy.
