Chapter 2
Spatial analysis
A good location decides whether an investment pays off before the first drawing exists. Leysa automates the retrieval of public spatial data and site analysis, so choosing a plot and starting a project takes hours rather than weeks.
GIS for renewables, real estate and design
Who it’s for: renewable and real estate developers, design offices, local authorities.
The problem: data on plots, zoning plans and surroundings is scattered across many services, and collecting it by hand for every site takes days.
What Leysa delivers:
- automated retrieval and integration of public data: Geoportal, land registry, zoning plans (MPZP), weather data,
- plot search and selection by criteria: area, zoning, distances, grid access,
- site analysis for PV and wind farms,
- coordinate system transformations and spatial data clean-up,
- automatic generation of 3D site plans (the plot’s surroundings) as a project starting point.
Point clouds and photogrammetry
Who it’s for: design offices, contractors, surveyors.
What Leysa delivers:
- point cloud segmentation, classification and registration,
- photogrammetry and processing of 3D scans for use in design,
- conversion of results into formats used in the office (DXF, IFC, Revit, Blender).
Tools: QGIS and PyQGIS, geopandas, shapely, pyproj, ezdxf, laspy, open3d, OpenCV.
