Almost finished annotating junction file

I have almost completed annotating all of the junctions for the indoor graph model. The only floor I lack is floor 4. While I was messing around with the data today I saw several things that needed to be fixed. One of which is anomolous polygons throughout some of the datasets (most notably woodward_flr3_poly) there are several polygons that need to be labeled or deleted because there are way too many records in the table that aren't needed.

I will probably wait until next week when I don't have anything to do and tackle this. The PostGIS database will also need to be re-updated once I have all of this data finished and compiled. I am hoping that by the end of this month I will have a "1.0" version of the datasets and database completed with little to no errors in the data.

New annotation for network junctions shapefiles

Jianfei brought to my attention the fact that it is very hard to find out what junctions correspond to what on the graph he is making.

So what I am going to do is go through and manually annotate the network junction file to indicate what the junction is. The labeling schema will be similar to this:

Elevators : E###
Stairways: S###
Exit/Entrance: M###
Room: R###(alpha)
Everything Else (null): N###

This should make it a bit easier to interprete when he goes in and creates this floor centerline graph. I also added support for Z-coordinates and a spatial index on these new shapefiles.
