I have a Cube highway network and a TAZ boundary layer in ESRI format. I also have a line layer (also ESRI format) that describes transit lines. This is not a Cube PT network -- it's just a line layer. Is it possible to overlay the boundary layer with the line layer, then specify a buffer around the line layer (say, 0.50 mile), and then see an image showing how much of the buffer is within each TAZ's boundary? Then output a TAZ file listing the percentage of each TAZ's area that is covered by the buffered area? This is a very common problem in transit modelling and I know it can be done in ArcGIS. Can it be done in Cube Base? How?
It is possible to undertake the first part of your question directly in Cube, using the GEOPROCESSING tool. With this tool you can do the:
- Buffer of your line layer
- Intersect or Union of this Buffer layer with the TAZ layer
It is not possible to calculate the area and the percentage of overlaid area directly within the Cube GIS interface. It is possible instead to calculate these including Python ArcPy scripting (ref. http://community.citilabs.com/t/how-to-include-python-in-your-cube-application-manager-workflow/751).
Another function available for these types of analysis is the "Transit accessibility analysis" GIS tool (Cube Base Reference Guide - page 285 / Network Window > Advanced display configuration > Transit accessibility analysis).
