Some notes:
Investigation on possible conversion optiomization for vector data (LODs, Tiling system, libraries replacements)
TODO
Investigation on CityGML, CityJSON and KML specifications
TODO -> Next step
Investigation on possible conversion optiomization for point cloud (data management and visualization, tiling, merging)
While working on Torino Obj files we were able to cover a conversion using blender as a CLI tool. This was more related to meshes rather than point cloud
Investigation on point cloud classification (pythorc)
TODO
Investigation on alternatives for 3D Tiles (Mago3D)
At the moment not good results for point cloud and meshes, we could still test this with CityGML
Investigation on photogrammetry libraries (OpenDroneMap)
TODO
Investigation on 3DTiles merging operations: from multiple to single tileset (cesium tools)
We partially analyze this inside the Torino pipeline experimentation, we used some custom code to merge tilesets. They are json files so we simply create a new tileset with the merged tilesets as children with a url reference
Investigation on point cloud to mesh conversion
TODO -> Next step
IFC integration in the pipeline
TODO
@allyoucanmap I would like to finally update the status of this by further reviewing boundaries of https://github.com/geosolutions-it/digital-twin-toolbox/milestone/1 including other missing bits.
We should be able to generate a workflow that given predefined input data is able to generate the Digital Twin as a set of 3DTiles for a medium size city like Florence or Genova. The worflow should be characterized as follows:
Input data
Below is a non exhaustive list of input data which we shall be prepared to handle for most common use cases to arrive at the production of an Urban DigitalTwin. For the moment we leave out IOT/Sensors and simulations.
Data Preprocessing
There are a number of data preparation activities that needs to be performed. Here below we are highlightin some of them.
Expected output

The expected output of this activity is to create a complete report that covers what follows:
Here below a tasklist of activities is proposed:
