- A mosaic is composed of multiple input data.
- Medoid
- A medoid is representative object of a data set or a cluster with a data set whose average dissimilarity to all the
objects in the cluster is minimal. A medoid is similar in concept to mean or centroid, but medoid is always
restricted to be members of the data set.
- STC
- Short Term Composite methodology. A compositing methodology inspired by the WELD algorithm. It is used for shorter periods with less input data.
- WELD
- Web Enabled Landsat Data. The WELD project generates global composited and mosaicked True color Landsat 7 Enhanced
