RUNNING kNN

C-Program Implementation Package

C++ programs for implementing the kNN method have been written. The programs have been assembled into a package including all the necessary tools for estimation for both categorical and continuous variables, using Landsat data, and the new FIA 4-subplot cluster plot data. Estimation software includes a cross validation program for error estimation, an optimization program to find the best weights for different bands in satellite imagery, and the mapmaker for the actual kNN-classification. In addition, the package also includes sub-programs and data management tools.

Requirements for using the software

Landsat Imager Used


Minimum:
  • A geo-referenced satellite image in generic binary format
  • Field plot data in text file format
Optional:
  • Land use mask to speed up the estimation
  • Upland/lowland mask for stratification
