How To: Set the environment settings for ArcToolbox
Instructions provided describe how to set the environment settings for ArcToolbox.
Environment settings can be thought of as additional parameters that a tool can use to affect its results. They differ from normal parameters in that they do not appear on a tool's dialog box (with certain exceptions). Rather, they are values set once using a separate dialog box, and are then used by tools when they are run. There are over thirty environment settings that are arranged in six categories: general, cartography, coverage, geodatabase, raster analysis, and raster storage.
There are four levels of environment settings: application, tool, model, and model process. These four environment levels form a kind of hierarchy, where application level environments are the highest level. This article only discusses setting environmental parameters at application level; the following are ways to achieve this:
- In the ArcToolbox window, right-click the ArcToolbox entry and click Environments.
- From the Tools menu in any application, such as ArcCatalog or ArcMap, click Options and click the Geoprocessing tab. Click the Environments button, which opens the Environment Settings dialog box.
- Application environments can also be set at the command line; for example, to set up scratch workspace, use command "scratchworkspace c:\scratch”.
