Detailed Description
From the 1880s until the advent of computers and geographic information system (GIS) software, topographic maps served as the essential instrument for the integration and analysis of place-based information. USGS mapping techniques evolved over the course of more than 130 years from field surveys through photogrammetry to computer-based and GIS analysis currently in widespread use. The topographic map remains an indispensable tool for everyday use in government, science, industry, land management planning, and recreation.
