Processes - Analysis

This section contains the following topics:

• Buffer - Creates a buffer around an Item
• Cluster - Clusters Items together within regular, rectangular grid cells
• Create Thiessen Polygons - Creates Thiessen Polygons of influence around the hook point of Items
• Dissolve - Merges Items based on attribute values.
• Geodetic buffer - Creates a 'geodetic' buffer around an Item
• Intersect - Combines the Items using the intersect boolean operation
• QZone buffer - Creates a QZone buffer around an Item
• Subtract - Combines the Items using the subtract boolean operation
• Symmetric difference - Combines the Items using the symmetric difference boolean operation
• Union - Combines the Items using the union operation
• Viewshed (as Grids) - Creates 'Viewshed' Grids from the Item origin over source Grid Items from another Overlay
• Viewshed (as QZone) - Creates a'Viewshed' QZone from the Item origin over source Grid Items from another Overlay
• Viewshed (as binary Grids) - Creates 'Viewshed' Grids from the Item origin over source Grid Items from another Overlay, containing only the cell values 1 (in Viewshed) and 0 (not in Viewshed)

Note: Some properties in the above processes are mandatory and some are optional. Mandatory properties are shown in RED.
