![]() ![]() In a GIS, attribute tables are often joined or related to spatial data layers, and the attribute values they contain can be used to find, query, and symbolize features or raster cells. The attribute scheme, structure, and attribute values are inherited from the source layer to the split layers. In raster datasets, each row of an attribute table corresponds to a certain zone of cells having the same value. Now you have eight new MAP layers created based on the unique values of the “Continent” attribute. Note by default in the Field Properties that Allow NULL Values is set to Yes. The panel displays all of its attribute columns and values.0. Then open the data’s attribute table and select Add Field from the Table Options icon. tabular, and text analysis tools in the GeoAI toolbox The Image Analyst. Click the Edit Schema button at the bottom of the MAP Attributes panel. The ArcGIS Predictive Analysis Tools Add-In is a set of tools used by analysts. The Edit Schema dialog box displays the columns associated with the MAP Attributes table on the currently selected layer.1. Here, we entered the word “continent” as the prefix.ģ. Click Add to add a new attribute column.2. If you have a specific word you would like to include with the eight layers, enter the value for the “New layer prefix” option. ![]() Choose the world_area source layer, then select the option “Split art to new layer(s) by unique attribute value:”. To split this world_area layer into eight different layers based on unique values in the “Continent” attribute, we simply specify the Continent layer in the Split Layer dialog box.Ģ.With the “Continent” attribute, there are eight unique values: 1) Africa, 2) Antarctica, 3) Asia, 4) Australia, 5) Europe, 6) North America, 7) Oceania, and 8) South America. The world_area layer has many attributes and one of the attributes is about “Continent” information. If you own the layer or you are an administrator of your organization, you can view and edit data in the attribute table, and you can perform the following field management operations from the Data tab of the layer's item page: Add fields to or delete fields from the attribute table. If you have some data you would like to divide into multiple layers using unique values in an attribute, you might want to try using the Split Layer feature in MAPublisher.įor example, we have a MAP Layer of the world (world_area layer).
