How to Extract Landslide Slope and Grid Unit Using QGIS only

How to Extract Landslide Slope and Grid Unit Using QGIS only

Welcome to my recent developed tools, that will help you to learn how to build apply sophisticated steeps using easy built in tools.

Along this course, I (Omar F. Althuwaynee, PhD in GIS and Geomatics engineering) will help you to:

• To introduce into powerful function of processing tool boxes of QGIS

• Install free processing tools inside QGIS

• To understand the procedure of extraction of Grid units (GU) and morphological Slope units (SU)

• To produce training and testing data AUTOMATICALLY, to be used later as input for data mining models like logistic regression or ANN and more. in easy steps

• To easily run procedure with Less than 5 steps for each type of mapping techniques (GU and SU).

  
  

***** February 2022 UPDATE !!  *******

We have updated the "Model tools" named LaGriSU (Landslide-Grid-and-Slope-Units-QGIS_ToolPack), the current version :

1. Better performance and less time in processing

2. it works on QGIS versions  3.10, 3.12, 3.14 (64 bit & 32 bit) tested on both Windows and Linux

3. More robust hypothesis regarding to define landslide-free area (zones): I added 2 techniques | 1) Buffer zones, and 2) Slope value threshold

4. Both inventory of point and polygon features can be used

5. Comprehensive plots: Box plot to show the summary of different values statistics within landslides locations

6. Comprehensive summary reports: Summary of values statistics within landslides locations

   
   

    "QGIS as open source has very simple interface and FREE of charge available, therefore it is the great and powerful tool especially in third world based universities and not funded students."                                                 

At the the end of this course, you will be easily and efficiently able to use automatic process to build training and testing data for preparing landslide susceptibility mapping, using modeler of QGIS open source FREE software analysis capability.
