Example point

cloud to raster

transformation

Create a Digital Terrain

Model (DTM) and Digital

Surface Model (DSM)

from a point cloud.

Merge component values from

one point cloud to another.

Sort a point cloud by the

values of components.

Advanced

TransformationsUsing point cloud power

for Viewshed Analysis.

Viewshed Analysis

● Goal: Identify which land parcels have a view of the water

● Expressing a big data problem as a point cloud made the

impossible possible

● Millions of parcels and lines of sight = 17 billion points

○ Point clouds can handle this volume!

● Test if the DEM intersects with the line-of-sight points

Viewshed Analysis

● FME is extremely efficient when

handling point clouds and rasters.

● Many powerful transformers and

custom transformers are available.

● Try using point clouds for your big

data problems.
