The tool is intended for use by individuals, governments, NGOs, researchers, communities, and others seeking to address issues related to land degradation. LANDREST can be downloaded and used by anyone as long as the author is credited.

The LandREST Toolbox appears in the ArcToolbox window. Select the LandREST Tool.tbx file and click Open. In the Add Toolbox window, click the Connect to Folder icon and navigate to the location of the toolbox. Right-click the ArcToolbox window, and click Add Toolbox. Open ArcMap, and click Geoprocessing > ArcToolbox. Move the zip file to the directory where you want to store the toolbox. Model Builder Computing a Least-Cost Path Between Two Locations: In this exercise, you will identify the most cost effective path between two locations based on elevation slope and landuse type. This tool has been successfully tested in ArcMap 10.0/10.1/10.2. 4 Now you will make the buffer distance a model parameter. 3 Repeat the process, making the variable PDBuffer a model parameter as well. A P is 1 added next to the oval to show that it is now a model parameter. Soil erosion risk (SER) itself: This is the present risk of erosion in the area of study under the current human and livestock population distribution. Setting up interactive models 69 2 2 Right-click the output variable PDNotify, and then click Model Parameter. Potential soil erosion risk (PSER): This is the typical vulnerability of the soil to water erosion without taking into account vegetation cover or land use.Īctual soil erosion risk (ASER): Current risk of erosion under the present land use and vegetation cover conditions. It offers the following products to address soil degradation: The general structure behind it is inspired by the CORINE model with variables derived using the USLE. Geoprocessing models automate and document your spatial analysis and data management processes. So, what is ModelBuilder Esri defines ModelBuilder as a visual programming language for building geoprocessing workflows. Yes, you can build a model for your frequent analysis and tasks using ModelBuilder in ArcGIS. A simple model can solve a lot of your daily problems. It runs as an ArcGIS tool based on the ModelBuilder concepts. You necessarily don’t need to write codes every time. LANDREST is a land degradation model that can be used to spatially identify locations in an area of interest that are in risk of being degraded.
