Line of Sight & Viewshed Analysis

Line of Sight (LOS)

LOS draws a sight line between an observer and a target, then checks the elevation profile along it. Visible segments show green, obstructed segments red — wherever a hill, ridge, building, or tree rises above the line.

• Confirm an observation post can actually see a suspected enemy position
• Plan sniper hides and position forward observers for artillery
• Set up radio and microwave relay links that need clear line of sight
• Identify dead ground — folds the enemy could exploit to approach unseen

Single & Multiple Observer Viewshed

Viewshed extends LOS from one line to an entire area, testing every cell of surrounding terrain. Single-observer viewshed evaluates one vantage point; multi-observer viewshed combines several to show cumulative coverage or a per-cell observer count.

• Site OPs, radar, and sensor positions for overlapping coverage with no gaps
• Find concealed routes through dead ground for movement
• Run a reverse viewshed to learn where the enemy could observe from
• Assess a defensive perimeter for blind spots an infiltrator could use

Buffer & Concentric Range Rings

Draw circular zones for weapon ranges, threat radii, and standoff distances; or multi-ring fans for engagement envelopes — minimum, effective, and maximum range.

• Artillery and air-defence weapon range rings
• Safety and exclusion zones around ammunition dumps, demolitions, and minefields
• Security perimeters along borders, around bases, and VIP routes
• Blast and casualty radii for IED cordon planning

Elevation Cross-Section Profile

A live cross-section of the terrain between any two picks — observer and target, gun and impact, transmitter and relay. It shows exactly where the ground rises into the sight line and by how many metres, so you can calculate the mast or tower height needed to clear it. See an example profile on the live site.
