Base Map FAQs - 15 Found
USGS cartographers first leveraged cartographic decisions made for the USGS 1:24,000/1:25,000-scale series requirements, and for the new US Topo product using diverse landscape sample areas, such as varying densities of features, rural vs. urban, land cover, and territorial differences, for testing the base map at each scale. They also compared popular base maps already in use. The goal for cartography was to have a WYSIWYG (what you see is what you get) experience when you download data or the US Topo product. Also, decisions were made to show features for which you could download and extract data, so there is no data at this time that cannot be downloaded other than transportation features obtained from commercial road sources.
