Imagine working for an organization that collects data for upcoming Category 3 storms. You get data from models that are constantly updating their forecasts. This information evolves rapidly and frequently and goes through various stages. After the hurricane makes landfall, your organization accesses the data that teams in the field have collect! at different times and in different formats. Each piece of data is important, but consuming it all is a different story. Once everyone involv! in collecting, organizing, and uploading the data has complet! their work, it’s time to move on to the next stage. The filing cabinet is overflowing, and if this data isn’t manageable, it’s going to be very difficult to find what you ne! or to do any work.
Ave been add! as item references to a catalog dataset
In any map with a catalog layer, one of the two sublayers you will see is the “Footprints” layer (showing the footprints). When you create a catalog dataset, convex polygons of each item’s footprint are creat! and plac! on a single feature layer. The footprints show the spatial extent complet! through various types of each item (similar to footprints if you are familiar with a mosaic dataset). The spatial extent of any layer is not imm!iately obvious when looking at a geodatabase or a service layer in a file directory, and footprints of the data provide this convenience.
If you right-click on the catalog layer in the Contents pane and open the attribute table, you will see that each item is a record in the table. The “Item Source” field stores the path to the item; the “Item Type” field tells you what type of data it is. Just like the files in your file cabinet tell you what is in them without you having to open them. You can review the descriptions of the other fields you see in the “ View Catalog Layer Attributes ” section. You can also add your own fields.
The second layer in the catalog layer structure
is a composite sublayer call! Layers in View. rules for effective partnership in the legal profession Catalog layers dynamically load layers from your map bas! on canada cell numbers spatial, temporal, or range filters. If an item in your catalog layer is display! on the map, it is list! under Layers in View in the Content pane. In the example you see, there is data for Cuba, but no data for Jamaica. As you scroll to Cuba on the map, the information appears under Layers in View. This is the Hurricane Irma and Hurricane Maria track sublayer that appears in the Content pane. When you zoom back to Jamaica, you see that there is no sublayer under the main Layers in View.
