Finding an Apartment Using GIS Part 2

Yesterday I posted about how I narrowed my apartment search to smaller list using GIS techniques. If you have not read that one I highly suggest going back and reading Part 1 first.

I have my list but now there is another factor I want to include. I just received an offer for a part time job at PretendJob Inc. and I want my new home to be close to both the job location and to my school. I can use the same radius tool for this but now I have two, hopefully, overlapping circles instead of only one. The purple triangle represent my work and the blue dot is school, because I will be at school more than the job I made the circle for work bigger because I am willing to live farther from work than I am for school. 

Now I can see what apartments are within the two locations.

On the previous post I located the shuttle stops and what locations are within walking distance but the map I had was zoomed in on a 5 mile radius of the University. There were actually other shuttle stops farther than that 5 mile distance and I want to include those in my selection, who cares how far camus is if you have a shuttle! Had I not plotted all the shuttle stops I might have missed this cluster of apartments. 

Another scenario is if I wasn't looking for a apartment but a house. Since I can't simply google search "houses for sale", at least I don't think I can, I would narrow down the neighborhoods and look for houses either by driving around or searching real estate sites. I first outlined the residential area, then I will use similar tactics as before. This time instead of using a radial outline of something I want to be close to I will use it for something I don't want to be near. Let's pretend I am a terrible person and I hate children, dogs, and happiness in general. I don't want to live near a park or school, so I made a border around all the schools and parks and whatever is left is where I might like to live.

Now I know what areas to not look for a home if I was heartless. But in all reality school zones are quite annoying.

You can use these techniques for anything like the nearest grocery store or what school you want to go to (if you have options), in any city not just San Marcos. I had fun just messing around with the dry erase markers and plastic!

Finding an Apartment using GIS Part 1

For those who do not know, GIS (Geographic Information Systems) is a convenient way of saying putting several layers of maps on top of each other to make one detailed map. If you have used Google Maps you have used GIS. Even my earlier post about traffic maps was GIS, putting a layer of traffic severity on top of another layer including streets counts as GIS.

I am transferring from UTSA to Texas State next semester and I am looking for a new apartment in San Marcos, TX. Apartment search websites are great but because apartments have to pay to be on those websites it is not all encompassing. Yet, if you do a Google search for apartments it is overwhelming. How can one solve this problem? Da-da-da-dah! G-I-S!!!

Assuming that most people do not have the specialized software on their computer needed for GIS, I am going to do it by hand. So here are the supplies I need:

Clear Sheet Protectors (I used expandable ones because I thought it would work better but regular ones would be fine)

Dry Erase Markers (variety of colors)
String
Printer
Google Maps


Ok, so first I printed a map of the San Marcos area. I decided I wanted to live fairly close to campus so putting the printed map in the plastic sleeve I took a dry erase marker and string measured about 5 miles using the scale bare on the bottom of the map, in this case 5 miles equaled about 2 and a half inches. I attached the string to the marker and drew a circle, or a radius, of where I generally wanted to live. The blue dot is the center of campus and that was my base point.

Next, I printed a more focused map of San Marcos this time I did a search for apartments so all the apartments in the area will be represented by red dots. I also decided I do not want to buy a parking permit so I want to live in a place really close to a shuttle stop (Texas State has a shuttle system that serves the surrounding area). The Texas State website has a map of the shuttle routes but I want to compare that map directly to my map of apartments. Using a blue dry erase marker I notated the shuttle stops onto the plastic covered map of apartments in my radius. 

The blue dots represent shuttle stops and as I said previously the red dots represent apartment complexes. Now, what I will do is put this map, with the plastic sleeve still on, into another plastic sleeve (this is why I bought the expandable ones). Now I can draw on top of the shuttle map without effecting the original map or the map with just the dots. I drew circles around the shuttle stops, just like I did in the beginning with the whole city, only this time they will be smaller. I cleaned them up a bit so the lines do not overlap and now it looks like this:

My circles were just hand drawn, I did not use the string because they were so small. If I were using the computer software I could be really exact, down to the foot. Any red dot within the blue circles are a possibility and I can ignore the others. 

Now instead of a giant spread of a ton of apartments I have it narrowed down to about 25 and I have not even looked at floorplans, price, or anything like that. This list is narrowed down simply by geography! In the next post I will go further and explain more of what I can do with this but for now I have a manageable list of possible living situations.
