This tutorial is now obsolete. A new and updated version is available atNearest Neighbor Analysis (QGIS3) GIS is very useful in analyzing spatial relationship between features. One such analysis is finding out which features are closest to a given feature. QGIS has a tool calledDistance Matrixwh...

These polygons are commonly delineated on medium-scale photography (e.g., 1:15,000) by a photo-interpreter familiar with the inventory area, and displayed and stored in a Geographic Information System (GIS) layer as a forest cover map. Forest cover maps are used for multiple purposes ...

Nearest neighbor interpolation is a simple and efficient method used in digital imaging and geographic information systems (GIS) for estimating the value of an unknown data point within a dataset. The technique involves selecting the value of the nearest known data point without considering the values...
Examples of such emerging application domains are: Geographical Information Systems (GIS), Multimedia Information Systems, CAD/CAM, Time-Series Analysis, Medical Information Sstems, On-Line Analytical Processing (OLAP), and Data Mining. These applications pose diverse requirements with respect to the ...
By the end of this post, you will create a better land cover classification. All because you learned the highly effective nearest neighbor technique inobject-based image analysis. Or you might just learn something neat that we are going to see a lot more of in the future. ...
An all-k-nearest-neighbor (AkNN) query finds from a given object set O, k nearest neighbors for each object in a specified query set Q. This operation is common in many applications such as GIS, data mining, and image analysis. Although it has re...
