History in Motion Google Earth Timelapses and Historical Imagery Google Earth Pro (the desktop version of Google Earth) has offered historical imagery for many years. You can access that imagery by selecting the timeslider icon in the menu at the top of Google Earth when it is open on your desktop. Today, Google unveiled some updates to their Google Earth Engine Timelapse website that offers historical imagery in an online version of Google Earth. The timelapses are animations that play 35 years of satellite imagery. In the following video I demonstrate how to access the timelapses and the historical imagery in Google Earth. Applications for Education The timelapse and historical imagery could be useful in a science class to help students see how coastlines and other features of landscapes change over time.

topoView | USGS Accessing USGS topographic maps has never been easier TopoView highlights one of the USGS's most important and useful products, the topographic map. In 1879, the USGS began to map the Nation's topography. This mapping was done at different levels of detail, to support various land use and other purposes. As the years passed, the USGS produced new map versions of each area. TopoView shows the many and varied topographic maps of each of these areas through history. This interface was created by the National Geologic Map Database project (NGMDB), in support of topographic mapping program managed by the National Geospatial Program (NGP). Packed with new features and downloadable file formats The maps shown through topoView are from the USGS’s US Topo series and earlier Historical Topographic Map Collection (HTMC). At present, both the US Topo series and HTMC maps are offered as GeoPDFs through The National Map and the USGS Store. Send us your feedback
