Land Survey and 3D Terrain Modeling for Solar Sites and Building Placement
3D accuracy for land projects: measurement, modeling, and decision support.
We collect imagery by drone land surveying and turn it into a reliable 3D terrain model with photogrammetry. Your land survey becomes more than numbers. Slope, elevation changes, aspect, access roads, and environmental features are visible at a glance.
From city centers to hard-to-reach zones, building placement and ground-mount PV layout are planned to match site conditions. Shading impacts are predicted in advance. All deliverables are compatible with CAD, GIS, PVsyst, and PVSOL.
Problems
No current and integrated land survey data
When data sits in different sources with weak coordinate alignment and mixed resolutions, results become inconsistent. Micro-topography, slope, and aspect maps are unclear. Site selection, quantities, and cost estimates drift.
Gaps in difficult terrain
Steep slopes, slippery ground, and restricted areas leave parts unmeasured. If roads, streams, trees, and structures are not visible, access planning and safety assessment remain uncertain.
Shading uncertainty for PV and buildings
A land survey alone is not enough. Without modeling slope, aspect, and surrounding obstacles together, shading profiles are not realistic. Row spacing, inverter and transformer locations, and cable routes are misplanned, and energy estimates diverge from reality.
Land survey and 3D modeling: one flow from data to layout
Render-a carries land survey data into a 3D model. Uncertainty drops, shading errors shrink, and unnecessary site revisits are minimized.
Unified data in one coordinate system
With drone photogrammetry, Render-a merges orthophotos, point clouds, DSM or DTM, and contours in a single coordinate frame. Land survey data becomes consistent. Micro-topography, slope, and aspect maps are clarified, reducing siting and quantity errors.
Complete coverage in hard to reach areas
Smart flight plans capture critical zones, including steep slopes, slippery ground, and limited access areas. Roads, streams, trees, and structures appear in the 3D terrain model. Measurement gaps close, extra site walks decline, and risks are reduced.
Accurate planning for layout and shading
Sun-path simulation computes row spacing, offsets, equipment locations, and cable routes that fit the terrain. Outputs integrate with CAD, GIS, PVsyst, and PVSOL. Shading-driven deviations decrease, and design decisions move faster.
F.A.Q
Rendera generates digital terrain models (DTM) and digital surface models (DSM). These enable slope mapping, elevation profiling, volumetric estimations, and obstruction analysis. Such outputs are essential for solar farm planning, civil works, and large-scale construction.
Yes. Rendera is designed to handle high-volume datasets. Processing time increases with image count, but there is no strict project size limitation. For very large datasets, users may divide them into manageable segments without losing continuity.
The platform provides elevation adjusted layouts and slope-based analysis, allowing precise positioning of PV arrays, cable routing, and infrastructure placement. Models can be exported to PV simulation tools such as PVsyst and PVSol for energy yield studies.
Yes. Rendera’s land modeling engine is also relevant to agriculture, construction, and real estate. Models can be exported in formats compatible with CAD environments.
