How are data gathered in a layer represented?

Data gathered in a layer is represented with points, lines, shapes (polygons), or surfaces. You then use symbols, text, graphics, and images to visualize the data. Some layers are automatically added to maps when you create the map. Most of the time, however, you manually add layers to a map.

What do the layers represent in ArcGIS Online?

The data still resides in your map service and is not copied to ArcGIS Online. Layers represent geographic features such as points, lines, polygons, imagery, surface elevation, cell-based grids, or virtually any data feed that has location—for example, weather gauges, traffic conditions, security cameras, and tweets.

How to calculate the number of nodes in a layer?

This convenient notation summarizes both the number of layers and the number of nodes in each layer. The number of nodes in each layer is specified as an integer, in order from the input layer to the output layer, with the size of each layer separated by a forward-slash character (“/”).

Can a part belong to a layer in a diagram?

All Part s that are in a Diagram actually belong to a Layer in the diagram. You can control the visibility, Z-order, and various user permissions for all of the parts in each layer. Parts can be individually modified to toggle their visibility using Part.visible or Part.opacity .
