What is map scale?
Map scale is the ratio between a distance on the map and the actual distance in the terrain. A scale of 1:25,000 means that 1 unit on the map equals 25,000 units in reality: 1 cm on the map = 250 m on the ground. The smaller the scale number, the more detailed the map.
1:25,000 — Tactical map
The 1:25,000 map (also known as a "large-scale map") is the standard for field navigation and tactical operations. At this scale, individual buildings, tree groups, path kinks, and small watercourses are visible. Contour lines are at 10-metre intervals. This is the map for foot or all-terrain vehicle navigation over short distances.
1:50,000 — Operational map
The 1:50,000 map combines overview with detail. Paths, roads, villages, and prominent terrain features are visible; contour lines are at 20-metre intervals. This is the most commonly used military map scale for companies and battalions: large enough for overview, detailed enough for coordination. In MilMap this is the recommended zoom level for route planning.
1:100,000 and 1:250,000 — Strategic maps
At larger scales (smaller ratios) you lose terrain detail but gain overview. The 1:100,000 map shows an area of approximately 100 by 100 km on one A4 sheet. Suitable for brigade operations and larger units. The 1:250,000 map is used for strategic planning: division and corps level, the route from A to B over hundreds of kilometres.
Digital scaling in MilMap
In MilMap you zoom seamlessly between scales. The map layers are dynamic: at a high zoom level (1:25,000 equivalent), detailed topographic elements are visible; zooming out gives the operational overview. Save offline map data at the zoom level you need for the operation — higher resolution requires more storage space.
Choosing scale for planning vs. execution
Planning phase: use 1:50,000 for an overview and to identify the general route. Detailed planning: zoom in to 1:25,000 for all waypoints and time calculation. In the field: navigate at 1:25,000 but keep a 1:50,000 overview map at hand for broader orientation. MilMap supports multiple map layers simultaneously.
