Transforming Rasters & Point Clouds
Transforming Rasters
& Point Clouds
Agenda
• Point Clouds and Rasters in FME• New in FME 2016.1
• Do more with third-party tool
integrations
• LAStools
• ImageMagick
• Example point cloud to raster
transformation
• Advanced transformations for
big data problems• Viewshed Analysis with point
clouds
New in FME 2016.1
• Autodesk ReCap
• Cesium 3D Point Clouds
• Sentinel 1 and 2
Third-Party
Tool
Integrations
Make even more
with LAStools and
ImageMagick.

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.
