In this video I provide a basic tutorial on how to build an expert system to automatically extract land cover features from high-resolution imagery and LiDAR. Sorry for some of the weird noises in the background. That's my cocker spaniel snoring.
The data consists of a 4-band digital orthophotograph from the National Agriculture Imagery Program (NAIP) and LiDAR point cloud LAS file acquired by the USGS. The NAIP orthophoto is from the summer of 2010 and the LiDAR point cloud is from the spring of 2011. You can download both the imagery and the LiDAR from this link.
The process is quite simple and makes use of a few different software packages. The steps are as follows.
1) Data exploration in ArcGIS and Quick Terrain Modeler
2) LiDAR surface model generation in Quick Terrain Modeler
3) Feature extraction using eCognition
4) View results in ArcGIS.
