![]() ![]() Both of these groups of fields can be used in various applications. ![]() You have now identified groups of attribute fields that can be used in layers created specifically for different users and roles. Close the Fields view for the Trees layer. In the Fields view, note the fields associated with tree failure and risk. They enforce data integrity by limiting the values to either a range or a list of valid choices.ġ4. They are used to constrain the values allowed in an attribute for a table or feature class. Note: Attribute domains describe the valid values for a field. In the Fields view, note the fields and associated domains used for tree identification. This difference is important, since one data source can have multiple layers associated with it.ġ3. However, changes made to the layer-level fields only change that specific layer. When you make changes in the Data Source view, the changes are made to the underlying data source, which includes all the layers that are based on that source. On the Data tab, in the Design group, click Fields. With the Trees attribute table active, click the Data on the Feature Layer tab.ġ0. You cannot use spaces or special characters in the field name, so a field alias allows you to give the field a more descriptive name.ĩ. Typically, field names are as short as possible to describe the data stored in that field. Field aliases allow you to assign an alternate name for a field. This indicates that the source feature class has field aliases assigned to the fields. Notice that the layer’s field names are descriptive and contain spaces. This table has no records, as you are creating feature layers for use by editors who will be collecting new tree features. You may need to dock and scroll the attribute table to review all fields. Review the Trees attribute table and note the field names. In ArcGIS, rows are known as records and columns are referred to as fields.Ĩ. Optionally move and dock the attribute table below the map.Īttribute information in a table is organized into rows and columns. ![]() Double-click the file to unpack the project package and open ArcGIS Pro.ħ. Note: Alternatively, you can download the project package, start ArcGIS Pro, and unpack the package. Click Configure Feature Layers and choose Open in ArcGIS Pro to download the item. Your feature layers may be used in hosted feature layer views that allow you create multiple unique windows into your data, and customize them to fit your audience.ġ. The objective is to control feature layer behavior to create unique and efficient feature templates for editing. The layers and their associated feature templates may then be shared as layer files, layer packages or web layers and can be used across a wide range of applications in ArcGIS. In this blog, you will configure several feature layers from a single feature class contained in a geodatabase. Often these are feature classes contained in a geodatabase, but they can also be shapefiles or online feature services. Feature layers can use data from any source that provides point, polyline, polygon, multipoint, or multipatch vector feature data. Feature layers are how ArcGIS Pro represents feature classes. Click the Elevation tab.A feature layer is a layer containing a group of similar features and their associated properties. In the Contents pane, right-click Penn_State_2D_Footprints and choose Properties.Now, you will modify the display of the 2D buildings layer so you can see them more clearly. Later on, it will contain the 3D buildings you construct. There is also another layer, Penn_State_3D_Buildings, which is a multipatch layer and can store complex textured 3D shapes. You will set the elevation properties for this layer so that you can better see the buildings. That's because they are shown in a 3D environment and the 2D polygons are partially covered by small differences in the terrain elevation. The same 2D building footprint layer, Penn_State_2D_Footprints, is displayed in the Scene view, but you'll notice that the two building footprints aren't fully displayed and seem to sink into the ground. Local scenes are useful to display 3D datasets that have a limited spatial extent, and are displayed with a projected coordinate system, such as a city or, in the case of this exercise, a university campus. ![]()
