Common Pain Points in Renewable Energy Projects and How LiDAR Helps
Pain Points
Inaccurate terrain data leads to costly solar panel layout revisions
Remote wind energy sites are difficult and expensive to survey conventionally
How LiDAR Helps
Aerial LiDAR produces centimeter-level Digital Terrain Models (DTMs) that reveal exact ground conditions under any vegetation cover. Solar farm designers use this to optimize panel tilt, row spacing, and drainage plans before breaking ground — minimizing rework and budget overruns.
Airborne LiDAR surveys cover hundreds of hectares per flight day, penetrating canopy to deliver bare-earth models of even the most rugged terrain. Wind turbine siting and access road design can proceed with full confidence in the underlying topography.
Hydropower projects require watershed data that's hard to capture at scale
LiDAR-derived hydrological models accurately delineate watersheds, identify drainage networks, and calculate reservoir storage volumes. For projects near or crossing water bodies, Bathymetric LiDAR extends coverage below the waterline in a single integrated survey.
EIA and permitting submissions need survey-grade data that agencies will accept
AB Surveying delivers fully georeferenced, survey-grade LiDAR datasets with documented accuracy reports — accepted by DENR, DOE, and other Philippine regulatory bodies. Our deliverables are formatted for direct submission to EIA consultants and permitting agencies.
Vegetation and land cover analysis is slow when done manually
LiDAR point clouds distinguish ground, low vegetation, shrubs, and tree canopy automatically. Combined with orthophoto overlays, our teams deliver classified land cover maps that fast-track environmental baseline studies and clearing cost estimates.
Solar Farm Site Assessment
Terrain analysis for optimal panel placement, slope grading, shadow modeling, and drainage design for utility-scale solar farms.
Hydropower Watershed Modeling
Catchment delineation, flow accumulation, and reservoir volume estimation for run-of-river and storage hydropower projects.
Transmission Line Route Planning
LiDAR corridor surveys for power evacuation infrastructure — connecting renewable energy plants to the national grid efficiently and safely.
Bathymetric Survey for Coastal RE
Aerial Bathymetric LiDAR for offshore wind and tidal energy feasibility — seamless land-to-seabed topographic coverage for near-shore projects.
Wind Energy Site Mapping
High-resolution terrain models for turbine placement, access road routing, and tower foundation engineering in ridgeline and coastal wind sites.
Geothermal Terrain Analysis
Slope mapping and infrastructure corridor planning for geothermal energy development in volcanic and mountainous regions.
EIA Spatial Data Support
Survey-grade geospatial datasets for Environmental Impact Assessment submissions — data in regulator-ready formats.
Construction Progress Monitoring
Repeat LiDAR flights during construction to track earthworks progress, verify cut-and-fill volumes, and confirm as-built conditions.
3D Colorised Point Cloud Data
A point cloud data containing millions of precisely located points overlaid with orthophoto RGB creating a realistic 3D city model.
PROJECT SPOTLIGHT
A renewable energy developer required a full topographic survey of a 350-hectare candidate site before committing to FEED. The site had mixed vegetation, significant micro-relief, and no reliable existing survey data. AB Surveying deployed an Aerial LiDAR system and completed data acquisition in two flight days, delivering a 5cm-accuracy DTM within two weeks of mobilization.
The resulting terrain model revealed a drainage channel bisecting the proposed panel array — a feature invisible in the available satellite imagery — saving the client an estimated ₱8M in panel foundation redesign costs.

Featured Projects
We were amazed at how fast AB Surveying and Development's LiDAR mapping was as compared to conventional surveying methods.
With approximately 1,000 hectares of land area, the Kiangan, Ifugao project site was accurately generated as a topographic map and was very useful for the planning and design of the proposed Hucab Mini Hydro Electric Plant. The team was very accommodating and helpful in every step of the way, and they almost eliminated the need for physical site inspection because of their attention to detail!
Highly recommended to all our industry peers!
