things should be "easy" - the dataset's coordinate reference system (CRS) would be reported by the QgsPdalDataProvider (just like with other QGIS data providers) and we would let QGIS core classes handle CRS and on-the-fly transformations (including datum shifts) - with the help of PROJ o...
With acceptance ofQEP #194 Point Clouds in QGISpoint clouds became a first class citizen in QGIS with own layer type, data provider and renderer. However, native data management and analysis possibilities for point clouds remain quite limited, especially when compared to raster, vector and mesh l...
QGISis a professional GIS application (FOSS) that supports our open web services for orthophotos. Supported connection: Orthophoto web service (open standard WMTS link, XYZ & TMS tilemaps) Surface model (colored hillshade and contour lines) web service (open standard WMS & WMTS links) ...

QGIS is free software. If you don't know about this little gem, you need to. It is indispensable for working with and being able to clip public elevation data (not necessarily point clouds, but surface data). Agencies give you the data, hooray for democracy, but make it available...
You can use the following free and open source software to open the files generated in ODM: .tif (GeoTIFF): QGIS .laz (Compressed LAS): CloudCompare .obj (Wavefront OBJ), .ply (Stanford Triangle Format): MeshLab Note! Opening the .tif files generated by ODM in programs such as Photosh...
For reproducibility and benchmarking purposes, our pipeline was developed using a mix of open-source software packages (e.g., QGIS, OSM data, AirSim) and commercially available software that offers free access to the academic community (e.g., ContextCapture). To facilitate usage, we have not ...
a 3D modeling tool. The performance is tested using different hardware and input data. The processing times are less than 8 min, and 8 GB of memory is used with 4 to 16 core processors and point clouds larger than 100,000 points. The tool is, therefore, easily usable on common ...
If you are looking for an accessible Python package to write the Python equivalent of yourGDALcommand lines, or of yourQGISanalysis pipelinewithout a steep learning curveon Python GIS syntax, GeoUtils is perfect for you! For more advanced users, GeoUtils also aims at being efficient and scalable...
Geo-referenced point clouds were created from photographs of 30 trees belonging to five savanna species. For each tree, 20 horizontal stem slices, with increasing thicknesses of 1 to 20 mm were made at breast height using the open source QGIS software. The resulting cross-sections were manually...
