One can create any number of layers from a given dataset, each of which can contain a different selection of features.)Īs with the Select tool, with the Make Feature Layer tool, attribute selection can be specified using the Expression parameter, into which an SQL query can be written: It can be used as input to other tools within the model and can contain a selection. (A layer is a temporary representation of a dataset that is not stored on the hard disk, but exists only in the computer's operating memory and is automatically deleted after the model run. It does not create a new dataset (as was the case with the Select tool), but only a layer. The second option is to use the Make Feature Layer tool (ArcToolbox -> Data Management Tools -> Layers and Table Views). The first is to use the Select tool (ArcToolbox -> Analysis Tools -> Extract), which applies an SQL query to the layer and creates a new dataset from the selected features. When subsequently clipping with the Clip tool, it would then be sufficient to use the district layer as the clipping layer, in which a selection would be made. If we solved the task by running individual tools and not using a model, then we would select the district manually with the Select Features tool. (Step 4 might seem a bit mysterious, we'll discuss it in detail later.) Using zonal map algebra, calculate the (relative) area of forests.Create a buffer zone with a radius of 300 m around the tracks.Clip the layer of railway tracks with the selected polygon.Select the polygon of the Jindřichův Hradec district.There are several possible solutions, one of which can be the following:

Let's say we want to solve the problem for the Jindřichův Hradec district.

ZONAL STATISTICS ARCGIS HOW TO
If you do not want to deal with downloading and editing data or you do not know how to do it, you can download the prepared data here. So we need a raster that will only have these five values instead of three-digit codes ( Reclassify tool). We will work with the basic categories: 1 - urban areas, 2 - agricultural areas, 3 - forests, 4 - wetlands, and 5 - water bodies. As is well known, the Corine Land Cover is coded with three-digit codes, the first digit expressing the basic categories, the second digit the more detailed categorization, and the third digit the most detailed one.
