Analyze Terrain Using Satellite Imagery

Zeroing in on the search area begins with analyzing terrain using satellite imagery.

You'll want to access high-resolution satellite images of the region where the missing person was last seen. These images provide a bird's-eye view of the landscape, allowing you to identify key features that could impact the search.

Look for natural barriers like rivers, cliffs, or dense forests that might limit movement. Identify potential shelter areas, water sources, and clearings where a lost individual might seek help.

Pay attention to elevation changes, as they can affect travel speed and direction. Note any man-made structures, roads, or trails that could serve as reference points or potential destinations.

Use mapping software to overlay grid patterns on the satellite imagery. This will help you segment the search area into manageable sections.

Consider seasonal changes that might affect vegetation cover or water levels. If possible, compare recent images with older ones to spot any significant landscape changes.

Establish Probability Zones

Establish probability zones by defining high-likelihood search regions based on your initial data and analysis.

You'll want to use terrain analysis tools to identify areas that match the victim's last known location and potential routes.

Consider the victim's likely behavior patterns, such as seeking shelter or following natural pathways, to further refine your probability zones.

Define High-Probability Search Regions

Once you've gathered all available information about the missing person or vessel, it's crucial to define high-probability search regions. These areas are where you'll focus your initial search efforts, maximizing the chances of a successful rescue.

To identify these regions, analyze the data you've collected, including last known location, weather conditions, and terrain features.

Consider the subject's capabilities, such as their physical fitness or vessel characteristics, to determine how far they might've traveled. Factor in any potential hazards or obstacles that could influence their movement. Use this information to create a map overlay highlighting the most likely areas where the subject may be found.

To further refine your high-probability search regions:

1. Prioritize areas with natural shelter, water sources, or other survival necessities
2. Identify potential routes the subject might've taken based on their known intentions or habits
3. Consider areas where previous successful rescues have occurred in similar situations

Use Terrain Analysis Tools

With terrain analysis tools at your disposal, you can establish more precise probability zones within your high-priority search regions. These tools help you factor in landscape features, vegetation density, and elevation changes that might influence a lost person's movement or survival chances.

Start by using digital elevation models (DEMs) to create slope and aspect maps. These will highlight areas that are more challenging to traverse or might funnel movement in specific directions. Next, analyze vegetation cover using satellite imagery or LiDAR data to identify dense forests, open fields, or water bodies.

Tool	Purpose	Data Source
DEM	Elevation analysis	USGS, NASA
Slope Map	Identify steep areas	Derived from DEM
Aspect Map	Determine sun exposure	Derived from DEM
Vegetation Map	Assess cover density	Satellite imagery

Combine these layers with known behavioral patterns of lost persons in similar terrains. You'll create a composite map that highlights areas where the missing individual is most likely to be found. Remember to take into account seasonal changes, weather conditions, and the person's physical capabilities when interpreting these probability zones.

Consider Victim Behavior Patterns

Victim behavior patterns play a crucial role in establishing probability zones for SAR missions. You'll need to analyze historical data and research on lost person behavior to predict likely movements and locations.

Consider factors such as age, physical condition, mental state, and outdoor experience when evaluating potential victim actions.

To effectively use victim behavior patterns:
