Forest Resources Inventory leaf-on LiDAR

Single photon lidar light detection and ranging (SPL LiDAR) is an active remote sensing technology for:

* mapping vegetation aspects including cover, density and height
* representing the earth's terrain and elevation contours

We acquired SPL data on an airborne acquisition platform under leaf-on conditions to support Forest Resources Inventory (FRI) development.

FRI provides:

* information to support resource management planning and land use decisions within Ontario’s Managed Zone
* information on tree species, density, heights, ages and distribution

The SPL data point density ranges from a min of 25pts/m. Each point represents heights of objects such as:

* ground level terrain points
* heights of vegetation
* buildings

The lidar was classified according to the Ontario lidar classifications. Low, medium and tall vegetation are classed as 3, 4, 5 and 12 classes.

The FRI SPL products include the following digital elevation models:

* digital terrain model
* canopy height model
* digital surface model 
* intensity model (signal width to return ratio)
* forest inventory raster metrics
* forest inventory attributes
* predicted streams 
* hydro break lines
* block control points

Lidar fMVA data supports developing detailed 3D analysis of:

* forest inventory
* terrain
* hydrology
* infrastructure
* transportation
* other mapping applications

We made significant investments in Single Photon LiDAR data, now available on the Open Data Catalogue. Derivatives are available for streaming or through download.
