Topographic maps for general use are available at 1:50,000 and 1:100,000 from the Hellenic Military Geographical Service (HMGS). They use a national projection system called EGSA'87, which is a Transverse Mercatorial Projection mapping Greece in one zone. A few areas are also available at 1:25,000.
t. e. A projected coordinate system – also called a projected coordinate reference system, planar coordinate system, or grid reference system – is a type of spatial reference system that represents locations on Earth using Cartesian coordinates ( x, y) on a planar surface created by a particular map projection.

Non-conforming maps help make the National Topographic System (NTS) more efficient. Generally, non-conforming map sheets can be identified by their irregular lines on the grid; however, some non-conforming 1:250 000 maps are identified by a light/dark pattern of lines and repositioned labels.
Sep 29, 2022 · The Topographic Change working group is defining the concepts, practical tools, and design for a national scale mapping and monitoring system that will enable an ongoing nationwide assessment of multi-scale 3D changes in the Earth’s surface, both natural and anthropogenic in origin, and demonstrating its functional capabilities for the ...
Topographic maps produced by Natural Resources Canada conform to the National Topographic System (NTS) of Canada. Indexes are available in three standard scales: 1:1,000,000, 1:250,000 and 1:50,000. The area covered by a given mapsheet is determined by its latitude and longitude. 1:1,000,000 mapsheets are identified by a combination of three ...
