A 1:50 000 scale topographic map. This is added to the IMW zone number and another unique number is created. We maintain a complete national topographic map and data coverage at 1:1 million and 1:250000 scale. At a map scale of 1:100000, 1 kilometer on the ground is equivalent to 1 millimeter on the map. They were essential for integrating and analyzing place-based information, and were widely used by receationalists. Read below for the details and contact us with the location you'd like mapped and we'll get started. Once downloaded, maps can be printed by anyone and are suitable for large-format printing – see ‘How to print our maps’ below for instructions. Sizing, scale, map detail, and pricing depends on what geography you'd like included in the map. For example, a 1:100000 scale map is considered a larger scale than a 1:250000 scale map. Geoscience Australia has complete 'small scale' reference map coverage of Australia at scales of 1:2.5, 5, 10 and 20 million. Topographic map coverage of Canada is based on the National Topographic System (NTS). Topographic maps are a signature product of the USGS.

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.
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.
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. These are each numbered 1–12 in a regular pattern. 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. Our digital maps are available for free download to any device.
