  • Patent number: 8064692
    Abstract: A false color composite image is created by assigning mid infrared data from three time-spaced images of an area of interest to corresponding RGB color components for the false color composite image. The RGB color components for the false color composite image are then converted into color space data and classified into a number of color classes. An age is assigned to the color classes to create a classified image of age classes of the area of interest.

  • Publication number: 20110242521
    Abstract: A method and apparatus for identifying individual trees and its canopy shape in LiDAR data determines if the view of each LiDAR data point is blocked by one or more neighboring LiDAR data points. LiDAR data points that do not have neighboring LiDAR data points that block the view are considered to be a central part of a tree canopy. In one embodiment, those LiDAR data points that are central part of a canopy are added to an output file that stores clusters of data points for each canopy detected. The central part of the canopy area can be analyzed to predict one or more characteristics of the tree.

  • Patent number: 7974813
    Abstract: Aspects of the present invention are directed at using LiDAR data to identify attributes of vegetation. In this regard, a method is provided that identifies the location of individual items of vegetation from raw LiDAR data. In one embodiment, the method includes selecting a coordinate position represented in the LiDAR data that generated a return signal. Then, a determination is made regarding whether the selected coordinate position is inside a geographic area allocated to a previously identified item of vegetation. If the selected coordinate position is not within a geographic area allocated to a previously identified item of vegetation, the method determines that the selected coordinate position is associated with a new item of vegetation. In this instance, a digital representation of the new item of vegetation is generated.
