Interfacing with existing Mecklenburg Master Address Locator

I have obtained the master address locater for Mecklenburg county. This data is stored in a shapefile as point features with a large amount of database info. Each point on the map below represents an address that has been geocoded, the table beside of it represents the attribute data for that specific address:



I will use this existing data to create the references to indoor locations. I believe by giving each room a point in the address locater, it will be possible to do query's and other such data manipulation with the indoor data. Since I already have the point locations for Woodward hall it will be as simple as copying and pasting the points into the Master Address table and updating the attribute information.

Since there is no "standard practice" for indoor geocoding I will have to develop a model to use that will enable me to do query's and location analysis the same way as regular addresses.

Once this is finished I should be able to facilitate route finding indoors by not only selecting points in space, but also by running queries on the location name or room number itself.

Goals for this week...

Today I have mainly been collecting datasets and other things so that I can continue making improvements to my prototype. The first thing that I have now is a coverage that has the latest street centerlines. However, it seems to not be entirely complete for UNCC so I will have to later change it to a shapefile so I can add roads to it. It will also be unnecessary to build a network from the shapefile in order to do analysis on it.

I also need to start the process of creating the hallway networks in GIS. For now I am only going to focus on just the centerline shapefiles and creating a network out of them, then connecting them to the existing street centerline files.

If time allows, I also need to clean up the work I did previously and correct some alignment issues that I have been having.

I hope to start following a new data model that I have stumbled upon on the web. It's referred to as the Building Information Spatial Data Model (BISDM) and relates to indoor GIS applications. I am sure that this will come in handy in the future, the link is http://bisdm.org/information/
