Exercise 6: Analyzing Raster Data for Landslide Susceptibility in Oregon

Goal: Continuing to use PyScripter and use numerous raster and vector tools to find common landslide characteristics throughout Oregon.


Methods: For this exercise we again utilized PyScripter to create a script from start to finish that focused on analyzing areas of Oregon that commonly have landslides. Numerous factors were examined including precip values, slope and land use along with tools such as buffer, adding a field, calculating a field, creating an update cursor and zonal statistics. With this data and tools a script was created to be used in looking at landslides in Oregon and use it to locate areas that are more susceptible than others. With the way this script was created it is portable and can be used in other scenarios aswell.


Results: The completed script can be found below (Figure 1). An additional product was an excel file that shows a variety of land types in Oregon that have had landslides in the past. The only issues I ran in to were debugging some indentation errors that were extremely simple to fix and it made sense to me why the script was not running to completion.
