More Progress

It seems that I have finally corrected any errors that were occuring that were sending Jianfei's graph out of whack. These seem to have been most disconnection errors or labeling errors. We have been running tests using the path-finding algorithm and everything seems to be working OK. There are still some errors that are occuring due to problems with how the algorithm works and deciding on using stairways and elevators. These problems should be easy to fix.

Right now I am working on incorporating different data sources into ArcScene to try to create a composite scene with the graph model, woodward files, and other GIS data layers that might be relevent.

Here are some screens of how the graph is looking and a couple looks at the incorporated GIS data in ArcScene:



This mainly shows the internal structure of the hallways and paths to get around the building. This graph is what we will use for route-finding, and we hope this will eventually get incorporated into the street networks so we can do route finding on a larger scale (hopefully citywide)






These two images show how different data sources can be incorporated into our current work. I have created 3d building of the campus and added in roads and the woodward and cameron files. These files are obviosly much more detailed, however, having this type of view is nessessary not only to make it easier to visualize, but easier for an emergency worker to find their way around.
