ISOM is an acronym that stands for International Specification for Orienteering Maps. It refers to a standardized set of guidelines and rules for creating orienteering maps used in the sport of orienteering.
Orienteering is an outdoor activity in which participants use a map and compass to navigate through unfamiliar terrain and locate specific checkpoints. The ISOM serves as a reference document for mapmakers, ensuring that orienteering maps around the world are consistent and comparable.
The ISOM provides detailed instructions and specifications for various map elements and features, such as contours, vegetation, rock formations, and man-made objects. It defines the symbols, colors, and scales to be used in depicting these features, ensuring clarity and legibility on the map. Additionally, the ISOM specifies the necessary information to be included in the map's legend, such as scale, magnetic declination, and map revision date.
The use of the ISOM ensures that orienteering maps are accurate, reliable, and fair for all participants. It allows for consistent map interpretation and navigation regardless of the location or event, enabling competitors to rely on their map-reading skills rather than inconsistencies in mapping styles or conventions. Ultimately, the ISOM aims to provide a level playing field for orienteering events worldwide, contributing to the sport's integrity and fair competition.
