Map Scales 1:63,360 scale Bench Lake U.S. Department of the Interior U.S. Geological Survey Earth Science Information Center (ESIC) To be most useful, a map must show locations and distances accurately on a sheet of paper of convenient size. These are each numbered 1–12 in a regular pattern. Series Name: USGS 1:100,000 Scale Topographic Maps: Publisher: United States Geological Survey: Type: Topographic: Sub-Type: General Topographic: Scale/Resolution A 1:50 000 scale topographic map. These maps depict in detail ground relief (landforms and terrain), drainage (lakes and rivers), forest cover, administrative areas, populated areas, transportation routes and facilities (including roads and railways), and other man-made features. Geoscience Australia has complete 'small scale' reference map coverage of Australia at scales of 1:2.5, 5, 10 and 20 million. We offer a service that can source or create a topographic map within the United States and internationally. Numbering 1:250,000 Scale Topographic Maps. help@mapshop.com or 800-532-6675. They were essential for integrating and analyzing place-based information, and were widely used by receationalists. The next step in the numbering system is easy – based on convention, there are 12 individual 1:250,000 scale maps in an IMW zone. Read below for the details and contact us with the location you'd like mapped and we'll get started. Our digital maps are available for free download to any device. Sizing, scale, map detail, and pricing depends on what geography you'd like included in the map.

Once downloaded, maps can be printed by anyone and are suitable for large-format printing – see ‘How to print our maps’ below for instructions. We maintain a complete national topographic map and data coverage at 1:1 million and 1:250000 scale. After 125-year legacy of topographic mapping (1884-2009), the USGS embarked on an innovative future of integrating historical maps with computer-generated maps from a national geographical information system (GIS) database.

Topographic maps are a signature product of the USGS. For example, a 1:100000 scale map is considered a larger scale than a 1:250000 scale map. Topographic map coverage of Canada is based on the National Topographic System (NTS). This is added to the IMW zone number and another unique number is created.

At a map scale of 1:100000, 1 kilometer on the ground is equivalent to 1 millimeter on the map.
