In this situation, containment might seem to be the right relationship because you want to find campground buffers that contain Nassella tussock. Depending on the situation, you may want to know whether features intersect, contain, touch, or lie within a certain distance of other features. These tools can also be opened in the Geoprocessing pane.Ī key parameter for this tool is the spatial relationship to be evaluated. Finally, you'll calculate the amount of Nassella tussock within the buffers.įor convenience, some geoprocessing tools open in a floating window. Next, you'll see which of these buffers contain Nassella tussock. First, you'll create buffers, or proximity zones, around the commercial campgrounds. If your analysis shows that Nassella tussock grows near commercial campgrounds, agriculture officials can provide information to help campers identify and avoid it. Campers who come in contact with the weed during recreational activities may get seeds in their clothing or gear and take these seeds with them when they leave. ![]() In this tutorial, you'll look for Nassella tussock growing near commercial campgrounds (campgrounds for motorhomes).

Nassella tussock seeds are spread mainly by wind, but also by animals, people, and vehicles. It is unpalatable to livestock, which makes it a threat to pastoral farming. It spreads quickly, crowds out other grasses, and is hard to eradicate. It is now well established in the Marlborough and Canterbury regions on the South Island. Nassella tussock is an invasive weed accidentally brought to New Zealand in the late 1800s. For the best experience, use an online help version that matches your software version. You can either clip the input rasters prior to using this tool, or clip the output of this tool.The quick-start tutorials are updated at each software release. If you want a specific extent for your output raster, consider using the Clip tool. This tool does not honor the Output extent environment setting for enterprise geodatabases. If an improper colormap mode is chosen, your output may not be as expected. In this situation, use the Mosaic tool for rasters with different color maps however, you must choose the proper Mosaic Colormap Mode parameter value. When mosaicking with raster datasets containing color maps, it is important to note differences across the color maps for each raster dataset you mosaic. The GIF format only supports single-band raster datasets. When storing a raster dataset to a JPEG format file, a JPEG 2000 format file, or a geodatabase, you can specify a Compression Type value and a Compression Quality value in the geoprocessing environments. You can save your output to BIL, BIP, BMP, BSQ, DAT, Esri Grid, GIF, IMG, JPEG, JPEG 2000, PNG, TIFF, or a geodatabase raster dataset. If you do not set the pixel type, the 8-bit default will be used and your output may be incorrect. You must set the pixel type to match your existing input raster datasets. ![]() The Mosaic tool has more parameters available when combining datasets into an existing raster, such as options to ignore background and NoData values. The inputs must have the same number of bands and same bit depth otherwise, the tool will exit with an error message. ![]() The input raster datasets are all the raster datasets you would like to mosaic together. ![]()
