LiDAR vs Photogrammetry in Costa Rica:
Which Survey Do You Need?

Home › Blog › LiDAR vs Photogrammetry

If you're planning a drone survey in Costa Rica, one of the first questions you'll face is: LiDAR or photogrammetry? Both are powerful technologies, but they work very differently and each excels in specific situations. Choosing the wrong one can mean wasted money — or worse, data that doesn't meet your project requirements.

This guide explains both technologies in plain language and tells you exactly which one to use based on your terrain, project type, and budget.

How Each Technology Works

LiDAR (Light Detection and Ranging)

LiDAR works by firing millions of laser pulses per second from the drone toward the ground. The sensor records how long each pulse takes to bounce back, creating an extraordinarily precise 3D point cloud of the terrain below. The key advantage: laser pulses can pass through gaps in forest canopy, reaching the actual ground surface beneath trees.

Our equipment — the DJI Matrice 300 RTK with Zenmuse L1 LiDAR sensor — captures up to 240,000 points per second with centimeter-level accuracy, even in Costa Rica's dense tropical forests.

Photogrammetry

Photogrammetry works by taking hundreds of overlapping photos from different angles and using software to stitch them into a 3D model. It produces stunning, high-resolution color imagery and accurate terrain models — but only where the camera can see. Dense vegetation blocks the view, so photogrammetry maps the top of the canopy, not the ground beneath it.

Side-by-Side Comparison

Factor	LiDAR	Photogrammetry
Forested / vegetated terrain	✅ Penetrates canopy	❌ Maps canopy only
Open / cleared terrain	✅ Works well	✅ Ideal
Accuracy	±2–5 cm	±3–10 cm
Color imagery	❌ No color data	✅ Full color orthophoto
Works at night / low light	✅ Yes (laser-based)	❌ Requires daylight
Typical cost (10 ha)	~$1,800 USD	~$1,200 USD
Processing time	2–4 days	1–3 days
Best for	Forests, slopes, complex terrain	Farms, open sites, construction

When to Choose LiDAR in Costa Rica

Costa Rica's terrain makes LiDAR the default choice for many projects. Choose LiDAR when:

• Your land has forest or dense vegetation — LiDAR is the only way to see the true ground beneath the canopy
• You need precise topography for drainage or civil engineering — small elevation errors compound into large drainage problems
• The terrain is steep or complex — mountainous areas in the Central Valley, Osa Peninsula, or Caribbean slope
• You're doing cadastral boundary surveys — LiDAR's superior accuracy is critical for legal land registration
• You need forestry management data — canopy height, biomass estimates, tree density

When to Choose Photogrammetry in Costa Rica

Photogrammetry is the better choice when:

• The terrain is open and cleared — agricultural fields, pastures, cleared development sites
• You need high-resolution color imagery — crop monitoring, progress documentation, marketing visuals
• Budget is a priority — photogrammetry is 30–50% less expensive than LiDAR for comparable area
• You're mapping coastal or beach areas — flat, vegetation-free terrain
• Construction site documentation — tracking earthwork progress on cleared sites

Can You Use Both Together?

Absolutely — and for many large projects in Costa Rica, combining both technologies gives you the best result. LiDAR provides the precise terrain model beneath vegetation while photogrammetry adds color orthophoto coverage on top. We can plan a single mission that captures both datasets simultaneously, reducing total cost compared to two separate flights.
