GIS 5100 Applications in GIS - Module 2

LiDAR data set used for this analysis:

Tools used:
  • LAS Optimizer

This map shows the .las file that was used to run the two analyses below. 

Analysis- Calculate Forest Height:

Tools used: 
  • Point File information
  • LAS Dataset to Raster
  • Minus 
This map and chart shows the height of the forest. This is calculated by subtracting the values from the DSM non-ground points raster and the DSM ground points raster produced. These layers are produced using the LAS Dataset to rater tool. The chart below the map shows the distribution of return points in the dataset. 

Analysis- Calculate Biomass Density: 

Tools used:
  • Point to Raster
  • IS NULL
  • Con
  • Plus
  • Float
  • Divide

This map shows the density of the biomass for the study area. Notice the yellow areas on the map- the highest concentration of these show the effect of manmade structures on these values.
