Server backups, shapefile conversions, and progress on network creation

Now that I finally have an account on the Vis Center server, I have backed up all of my database files and other pertinent information there. I will be periodically updating a copy of the database each week.

I have also taken all of the feature classes and converted them into shapefiles so that Jianfei can use them for his program. These are stored on the server and on the local machine under the directory 'shapefiles'.

I have begun to create networks for each floor. I have finished the first floor and everything seems to be working well. I have been able to use the find route commands and map routes to rooms from the outside doors. The next step will be to create this data for each floor and somehow have them link up. This may be possible by inputting elevation data in the network.

Here are some screenshots of what the network dataset looks like along with the floor one datasets:


And here is a screen of the network by itself, the dark line indicates the shortest route between two points:

It's important to note that in order to maintain connectivity you have to have connections at endpoints connections along edges that are continuous will NOT WORK!! I tried this earlier by drawing whole line segments for hallways but it did not work since each connection point has to be an endpoint for connectivity to work correctly. Without this route finding will be erroneous or will not work at all.
