In the Editor pane, click Save to save your edits to the template.ġ7. If you want to rerun the RFT, you’ll need to make sure the data is accessible from the same file path or edit the template to point to a new input.ġ6. Notice that this input is blue- that means it is a constant input. The Protected Status raster is added as the input raster to Roads Feature Class. In the Rasterize Features Properties window, click OK.
You’ll still need to set the Input Features in the Raster Functions pane.ġ5. This raster has no effect on the roads layer itself it only determines the cell size and extent of the output. Open the Mountain_Lion_Corridors geodatabase and choose Protected_Status. In the Input Dataset window, browse to C:\Mountain_Lion_Corridors, or where you unzipped the lesson data. At the bottom of the Raster Functions pane, click the Create new layer menu and choose Save As.ġ4. The changes will be saved locally, so you can re-run the template as many times as you want without pulling it from the portal each time you need it.ħ. Once saved, you can change the parameters, add more functions, etc. In order to edit the template, you’ll need to save it to your project. Rugged terrain and dense landcover both help mountain lions stalk prey, like deer, coyotes, feral pigs, and other small animals. tend to be minimally developed, and will stay that way, making them not only ideal for mountain lions, but also attractive to conservationists trying to spend the least amount of money on a potential wildlife corridor. Protected status is another measure of this state parks, national forests, etc. Roads are dangerous for mountain lions, and serve as a proxy for development. Mountain lions tend to avoid people, as they scare away prey and can be dangerous. As you can see in the tool, the RFT requires four inputs that will help determine what is most important to a mountain lion when choosing a habitat. The rest of the functions in the chain are dependent on the output of the previous calculation. This RFT was written so that the model only needs four inputs. When opened, the Parameters tab of the RFT looks like geoprocessing tool. Right-click Mountain Lion Suitability RFT and choose Open Raster Function. If necessary, add the search term owner:Learn_ArcGIS.Ħ. Search for the Mountain Lion Suitability raster function template. In the Catalog pane, click the Portal tab and choose All Portal. In the Mountain_Lion_Corridors project, on the ribbon, click the View tab and choose Catalog Pane.ĥ. Raster functions can be helpful as they are calculated on the fly and allow you to make continuous tweaks to your model.Ĥ.
RFTs can be published to ArcGIS Online and added to multiple projects for use. Now that you have the data you need, you’ll open the raster function template (RFT).
Double-click the Mountain_Lion_Corridors.aprx file to open ArcGIS Pro. The raster functions template is based on the model that is built in this lesson- for more information about each dataset and the wildlife corridor issue in general, you can reference the Build a Model to Connect Mountain Lion Habitats Learn lesson.ģ. This data folder contains a geodatabase with data you’ll use in the raster functions template.

Download the Mountain Lion project zip file. This RFT was built based on the model in the Build a Model to Connect Mountain Lion Habitats Learn lesson.ġ. In this blog, you’ll save a RFT from ArcGIS Online and edit it to produce a suitability raster for mountain lion habitats. RFTs are fast and easy ways to process rasters that apply processing directly to each pixel on the fly without modifying the original raster or taking up storage space. To identify habitats suitable to the mountain lions’ needs, you’ll use a Raster Function Templates (RFTs) to weight several criteria and create a suitability raster. Mountain lions need room to roam, and the rugged mountains northwest of Los Angeles provide this protected species the space it needs to hunt and breed.
