Trees and Airplanes don't play nicely together. Many airports face the constant struggle of ensuring that obstacles, like trees, do not threaten the safe operation of arriving and departing aircraft. How does YYJ, located on the west coast of Canada, in area known for its especially large trees, deal with this issue? LiDAR is often used to capture the height of obstacles around the airport, but what do you do with all that data?
This presentation will show how FME is used by YYJ to manipulate the LiDAR data, develop cost estimates for removal and develop layers for an ArcGIS Online management tool.

FME Rescues the Rescuer!!
Confession of a FME Kleptomaniac – All these ideas are stolen
FME let me easily TRANSMOGRIFY the LiDAR data into usable data
products:
• Colourize the LiDAR Points
• Compare to the Airport’s Obstacle Limitation Surface (OLS)
• Identify Obstacles as 3D Areas and Assign IDs
• Create Cost Estimates for Removal
FME made the whole process easily repeatable with
all future LiDAR Datasets.
Transmogrify = transform in a surprising or magical manner.

Managing the Results with AGO
Use ESRI products to create Management Tools:
• AGO 2D and 3D Applications to Interact with the Data
• Manage Data Locally and Push to AGO using FME
• Use FME to Create Cost Estimates for Removal
• AGO 2D Dashboard Apps to Examine Removal Estimate Ranges
AGO = ESRI’s ArcGIS Online
