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
Read/write 75+ raster and point cloud formats
75+ raster and point cloud
transformers
View and inspect
New in FME 2016.1• Autodesk ReCap• Cesium 3D Point
Clouds• Sentinel 1 and 2
Raster opacity setting in FME Data Inspector

Demo: Creating a Fancy Animated GIF
Don’t be scared. This is the important
transformer here.
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.
AdvancedTransformations
Using 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.
