Extension for geoJSON and LIDAR data in LAS Format Reader/Writer for VTK
The vtkGeoJSONReader filter reads a geoJSON file specification and converts it into vtk compatible datatypes like vtkPolyData.
Current implementation of the reader supports the following geoJSON geometries
Point
Multi Point
Line String
Multi Line String
Polygon (Without holes)
Multi Polygons (Without holes)
The vtkLASReader filter reads LIDAR data in LAS format and converts it into VTK compatible vtkPolyData.
To Do:
For visualisation purposes, PointData in vtkPolyData will be modified according to the following point data properties:
The implementation is based on VTK version 6. At present, it is not compatible with older versions of VTK.
More information about the geoJSON format can be obtained here:
