Standard Practice for Symbols and Markings for Use With Land Search Maps
SIGNIFICANCE AND USE
4.1 The base map and overlays are used in managing a search by graphically tracking progress, resource allocation, and results. Standard symbols and markings allow a person to visually scan the map to obtain the status of the search without the need for a briefing or reading search documents.
4.2 Overlays are used for symbols which are likely to change during the search, that will cover other symbols or base map features, to prevent marking the base map, and to avoid too many markings at one time.
4.3 The symbols and colors have been chosen to be compatible with the symbols defined in Incident Command System Field Operations Guide ICS-420. This compatibility is either exact (for example, incident command post) or functional (for example, search area boundaries).
SCOPE
1.1 This practice covers the symbols and markings to be used with land search maps to show resources, search coverage, status, and results.
1.2 Operational usage of these symbols and markings, the resources they represent, and maps are not included in this practice.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview
ASTM F1846-98(2020), Standard Practice for Symbols and Markings for Use With Land Search Maps, establishes a uniform system for mapping symbols and markings used in land search operations. Developed by ASTM International, this standard ensures consistent and effective communication through the standardized use of symbols, colors, and overlays on search maps. Adoption of these best practices enables responders to quickly interpret the status of search areas and resource deployment, aiding in efficient incident management and coordination.
Key Topics
Standardized Symbols and Colors
The standard defines a set of symbols and color codes for indicating various resources (such as search crews, search dog teams, search patrols, helicopters, and fixed-wing aircraft) and for marking search areas, progress, and search results on maps.Base Maps and Overlays
Use of a base map (the principal reference map for a search area) is augmented by transparent overlays. Overlays facilitate the reuse of base maps and avoid excessive markings, preventing clutter and maintaining map legibility during ongoing operations.Compatibility with Incident Command System (ICS)
The symbols and colors are designed to be compatible with those used in the ICS Field Operations Guide ICS-420, supporting interoperability across emergency response teams.Clear Communication
By adhering to this standard, search managers and team members can visually scan a map and gather operational information-such as the location of resources, search coverage, and status-without extensive verbal briefings.
Applications
ASTM F1846-98(2020) has practical applications across a range of land search and rescue scenarios:
Search and Rescue (SAR) Operations
Enhance situational awareness and resource tracking in missing person searches, disaster response, and remote area incidents.Incident Command Centers
Support rapid decision-making and coordination at command posts by providing clear, universally understood map visuals.Training and Planning
Ensure that exercises, simulations, and pre-incident planning use recognized mapping conventions that will translate directly into operational contexts.Interagency Collaboration
Streamline communication between agencies and jurisdictions by using compatible map symbols and color codes, reducing confusion and errors during joint operations.Documentation and Reporting
Facilitate accurate recording of search activities and resource usage for post-incident analysis and reporting.

Practical Value
Implementing ASTM F1846-98(2020) standardizes map symbology for land search maps and overlays, ensuring all team members and stakeholders share a clear understanding of operational status, resource deployment, and search results at a glance. This clarity is essential for effective land search management, especially in high-stress emergency scenarios where rapid, accurate situational awareness can save lives.
