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

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.
