The principle of Model Builder is to create geoprocessing tools, which are by definition \u00ab\u00a0batch\u00a0\u00bb tools. This means that there is no interaction between the user and the processing, once launched. You define the input data and you retrieve the output data.
In some occasions this aspect is binding. Imagine that you have to run a model in using only a portion of the data set and if you use the Clip tool you will be duplicating the data, or else you want to select an area on the map and apply your geoprocessing model only to entities completely contained in this area. There is another possibility, the one we are going to follow in this example, we will use a template with a specific tool that requires an entry point, such as \u201cField of View\u201d and you want to enter manually the, or the, locations of the observer.<\/p><\/p>\n\n\n\n

Well, it is possible to do this with Model Builder using an ENTITY DATASET. You have never heard about it? Not surprising. It is really hidden!<\/p>\n\n\n\n

The Game of entities will replace, in your model, an input layer of the model. By indicating at the very launch, that this Entity dataset is a parameter of the model, the execution window execution will open up and you will have the opportunity to seize manually, either in the table or on the map, the input elements of the model.<\/p>\n\n\n\n

In the example we will discuss, you will click on the observation points that you want to process with the tool \u201cField of View\u201d, then you click OK and the model will run on the entered points.<\/p>\n\n\n\n

Setting up a<\/strong> classical<\/strong> model<\/strong><\/p>\n\n\n\n

We will build a classical model with Model Builder to calculate the \u201cField of View\u201d. We need a DTM and a layer of points as input. We will get as output a raster with pixels 1, for visible pixels from one or various, observation points and pixels 0, for non-visible pixels.<\/p>\n\n\n\n

The tool is located in the Spatial Analystr toolbox -> Size -> Field of View<\/p>\n\n\n\n
