Virtually the entire terrestrial surface of Earth has been mapped at scale 1:1,000,000. Medium and large-scale mapping has been accomplished intensively in some countries resulting in scales as detailed as 1:24K. National mapping programs listed below are only a partial selection of European bodies. Several commercial vendors supply international topographic map series which are also not listed below.
File-based 1:24K, 1:100K, 1:250K DRG TOPO Maps are available on a HDD at Terratracer and are indexed by both quad name and quad number (SGID Q Number). Terratracer also provides an EOD Bundle complete CONUS (Contingent USA) coverage, as well as a state-by-state package on a HDD.
The United States Geological Survey (USGS), a civilian Federal agency, produces several national series of topographic maps which vary in scale and extent, with some wide gaps in coverage, notably the complete absence of 1:50,000 scale topographic maps or their equivalent. The largest (both in terms of scale and quantity) and best-known topographic series is the 7.5-minute or 1:24,000 quadrangle. This scale is virtually unique to the United States and offers a convenient relation to customary units of measure where 1 map inch equals 2,000 actual feet. USGS also publishes 1:25,000 maps for metric uses, 1:100,000 maps covering 30 minutes latitude by one degree longitude, 1:250,000 covering one by two degrees, and state maps at 1:500,000 with California, Michigan and Montana needing two sheets while Texas has four. Alaska is mapped on a single sheet, at scales ranging from 1:1,584,000 to 1:12,000,000.

Produced by the Environmental Systems Research Institute (Esri, formerly ESRI), the Esri International User Conference (Esri UC) is the worlds largest event dedicated to geographic information system (GIS) technology. The 2015 Esri User Conference (UC) July 20-24 2015 will be held at the San Diego Convention Center in San Diego, California. The Esri UC dates back to 1981. In 2008, conference attendance grew to more than 14,000 attendees.
The conference offers more than 600 GIS user presentation sessions, 300 exhibitors, 275 technical workshops, 100 special interest, regional, and user group..
