2021-03-23 · The authors set out the principles and applications of spatial modelling and GIS and demonstrate its use in location decisions and strategic planning. Spatial Filtering means playing with pixel and its neighborhood pixels. A filter mask is moved in an image from point to point. At each point of an image, the response of the mask is calculated by the pre-defined relationship. There are lots of filters available in image processing but knowing every filter and its specialty is really important. Spatial pattern analysis allows GIS users to conduct different statistical methods using spatial data. For this assignment I conducted six different types of spatial analysis with seven outputs.

are being used to answer Jim's questions in the following sections. The filter type LOW employs a low pass, or averaging, filter over the input raster and essentially smooths the data. The HIGH filter type uses a high pass filter to enhance the edges and boundaries between features represented in the raster. Low pass filter. A low pass filter smooths the data by reducing local variation and removing noise. Most GIS packages provide simple grid filtering functions, whilst those that have a bias towards image processing and grid file handling (e.g. TNTMips, Surfer, Idrisi) tend to provide a broader range of functions.
