Safety fan & SDZ mapping

Show the full live-fire footprint in site context.

A clear map connects the firing layout and authorized use to the terrain, property limits and surrounding land. It gives the owner and reviewer one place to see what the range is working with.

The terminology

Safety fan and SDZ are related, not automatic synonyms.

Surface Danger Zone is common military range-safety language. Civilian ordinances and range organizations may instead use safety fan, projectile-containment area, shotfall zone, impact area or range footprint.

The map should use the term, method and components the reviewing authority expects. Before work begins, identify the written requirement, intended use, accepted source data and whether the final submission requires a particular credential or seal.

Map inputs

Build from named information, not assumptions.

The available information is checked against the requested use. Missing information is listed before the price, timing and map package are finalized.

Range geometry

  • Firing points and firing lines
  • Target points and target lines
  • Limits and direction of fire
  • Bay layout and simultaneous use

Operating basis

  • Owner-provided weapons and ammunition
  • Course-of-fire information
  • Existing use restrictions
  • Proposed expansion or change

Site context

  • Terrain and elevation
  • Parcel or survey information
  • Roads, trails and buildings
  • Water and neighboring land uses
The deliverable

A map package built for the next handoff.

The exact files depend on the project and reviewer. A typical package combines the mapped footprint with the data record needed to understand and update it.

  • 01Scaled safety fan or SDZ exhibit
  • 02Range layout and surrounding-receptor map
  • 03Multi-bay overlap or operating-option figure
  • 04Source, assumptions and open-item record
  • 05Agreed PDF and geospatial files
Common triggers

When this work usually starts.

Permit or zoning

The code asks for a safety fan

Map the requested range elements and surrounding site information under the authority's stated method.

Expansion or ammunition change

The authorized use is changing

Compare the proposed use against the existing range geometry, property context and other active bays.

Project-team support

A specialist needs the mapping layer

Provide documented GIS production while the responsible consultant, designer or authority keeps the final technical decision.
