Filters and searches work seamlessly with the map records table to get you the info you need with fewer clicks. Multiplying this scale factor by the width of a 3D mesh. (Heres a tutorial for doing this in Blender.) The 'z:x scale factor' describes how 'high' the current view is, on the z-axis, in terms of how wide the current view is on the x-axis. We've added the ability to preview maps within the interface and give you tools to compare any historical map with maps of the present. Import the resulting image as a displacement map in a 3D application to generate a 3D model of the terrain. The latest version of topoView is full of enhancements based on hundreds of your comments and suggestions. New functionality driven by your feedback Like the historical topographic mapping collection, we've added a variety of file formats previously unavailable for the US Topo series, including GeoTIFF and KMZ. Pretending the earth is a sphere makes the math simpler, but as youve found, this causes significant distortion at high latitudes. The US Topo series is a latest generation of topographic maps modeled on the USGS historical 7.5-minute series (created from 1947-1992). Web maps generally use a spherical mercator projection, and since I dont have the resources to re-render the entire planet, the terrain.party maps use this projection too. We've added the US Topo series to topoView, giving users access to over 3 million downloadable files from 2009 to the present day. The NGMDB project is proud to assist the NGP in bringing these maps to the Web. Geologic and topographic mapping have a long tradition together (see 1888 report). This interface was created by the National Geologic Map Database project (NGMDB), in support of the topographic mapping program, managed by the USGS National Geospatial Program (NGP). TopoView shows the many and varied older maps of each area, and so is especially useful for historical purposes-for example, the names of some natural and cultural features have changed over time, and the historical names can be found on many of these topographic maps. ![]() The most current map of each area is available from The National Map. As the years passed, the USGS produced new map versions of each area. This mapping was done at different levels of detail, in order to support various land use and other purposes. In 1879, the USGS began to map the Nation's topography. TopoView highlights one of the USGS's most important and useful products, the topographic map.
