Tutorial on using SCPAT: A MATLAB toolbox for the study of swath profiles

This tutorial introduces the input files which can be created and used for analyzing swath profiles. There are two types of input files: ‘data’ and ‘ID’. The data file’s format follows that of the output file available in SAGA-GIS software. In this format, any database file has six necessary columns to program work properly, i.e., ID, LINE, PT_ID, X, Y, and Elevation.
- ID: A unique number for each row that consists of the sequence of points on orthogonal profiles of each feature to be studied.
- LINE: An assigned number for each orthogonal profile of the feature(s) to be studied.
- PT_ID: An assigned number for each sampling point on orthogonal profiles of the feature(s) to be studied.
- X, and Y: longitude and latitudes of each sample point, respectively.
- Elevation: It could be replaced by another grid value such as slope or aspect. In the data file, the last necessary parameter could be introduced to SCPAT in its preference window using the column number of the corresponding field.
