export as vector: export point cloud data to a vector layer with 3D points export as raster TIN: export point cloud data to a 2D raster grid using a triangulation of points Whypdal_wrench? There are several reasons to usepdal_wrenchinstead of using PDAL API and building pipelines: ease of...
Visualization based on the viewport. A tool like QGIS might only read the geospatial data inside the user viewport rather than read the whole file. I'm not an expert in parquet, and it's not clear to me how to implement a geospatial index there. It looks like parquet includes something ...
