This week I have added two demographic layers to the map. One layer shows population density by census tract: the darker the orange, the higher the density. Higher population density, of course, means more potential passengers, and the proposed Purple Line extension clearly passes through a high-density portion of central Los Angeles:
The second layer demographic layer shows the proportion of each census tract over the age of 65. Darker green tracts have a high percentage of elderly residents. Because many of the elderly cannot drive, transit access is especially important in these areas:

DC Metro: Proposed Stops and the Areas that will Benefit
This map shows the five proposed WMATA metro stations and the various businesses, offices, and recreational areas it will serve. As it currently stands, the Washington D.C. metro leaves several key pockets undeserved, particularly areas with a vibrant night life, shopping, and physical recreation areas. As bus service hours are far more limited than metro, this causes complications for non-vehicle commuting to these locations.

-The arcGIS layer will not show until the zoom is increased a bit
This week I played with adding ArcGis layers into the proposed bus stop maps. After agonizing over the prospective layers I could add, I decided to include rail lines (excluding Expo line because I already had this shapefile from earlier this year) and libraries. Unfortunately neither rail nor libraries are very close to my area, so it’s not a very exciting map. Also, it seems that my existing bus stops are not being called.

The Westside North-South Connection website has gotten a “face lift” this week! Some major changes (and challenges) to this week’s website are as follows:
- ArcGIS layers- This week, thanks to the addition of ArcGIS server space, I added two demographic layers. I was surprised how easily I remembered how to access TIGER Files and Census data from American Fact Finder 2. Formatting the data and joining the files in arcGIS was not nearly as painful as I remember it being last quarter! However, when I tried to upload my files to Whippet they were not showing up. I realized that I had to export my joined file as a new shapefile and THEN upload it to Whippet. This is common sense (I had a “duh” moment) but it took me a bit of time to figure out.
- ArcGIS layer toggling- Another “fun” challenge was the toggling of ArcGIS layers. I worked with Erin and figured out that I toggle them as single layers and not arrays. I did notice that this does not always work as smoothly (or as quickly) as I would like, but I think this is due to limited server capacity (although, I am willing to accept blame if my code is hacked together).
- New format- The Westside Connection website got makeover! It now has tabable navigation. I also added in an address locator search bar.
- Uncaught references- Bootstrap is funky! A lot of times it will work perfectly fine but every once in a while it will say that Bootstrap’s call is not defined. Normally, refreshing does the trick!
Just when you thought it couldn’t get any more pink, it has! I have added pinkness. And Teal! Also, the WBTS site now has tabable navigation and some sweet layers that give a better sense of other people’s travel needs and current transit service. Yes!

Now the people using The Westside Connection can use the new layers feature to check locations of hospitals in relation to the metro as well as institutions. Institutions include a variety of places such as elementary, middle and high schools, some colleges and other places such as cemeteries. Also, users will be able to click on and off the LA County boundary and see where they are in the county and what is available within county boundaries.

This week I reached far back into the deepest corners of my brain to recall how to make a create a map via ArcMap in order to use the layer as an overlay on my Donut Metro map. Initially, I wanted to joint a spreadsheet of my own Census data to a census tract shape file, but even though I literally did that dozens of times last winter, I couldn’t remember how to do that. Instead, I just used two of UCLA’s Mapshare pre-set layers—population of kids 6-17 in each census tract.—and institutions. There were two reasons. First, these layers may be applicable to our final project. Second, kids like donuts and I like to eat donuts in institutions.
I had trouble with the toggle option. I didn’t realize that when you embed the toggle in the html code you have to assign the toggle button a unique ID. Before I had done that, the toggle worked erratically.

To enhance our Airport Connector bus route, I added two layers which I downloaded from UCLA Mapshare, Parks and Airports. After uploading these layers onto ARC GIS Server, we can now see a polygon where the airports and parks are located in Southern California. Click here for a full version of the map
Two additional layers were added to the website–Unified School District boundaries and local parks. The district boundaries will be useful to students/parents to know whether or not bus lines serve the area near schools their children currently attend or will attend. This is important for parents who are unable to pick-up and drop-off their children. My proposed will help to solve this problem. Parks were previously displayed on the map with custom markers and with Google Places, but neither of them brought out the boundaries of the park, so I wanted to make the parks pop out more. A park layer can be toggled on/off to highlight where the nearby parks and how the public can easily access them along these proposed bus lines.

In addition to students, we expect frequent usages of the new bus service from low income households and the elderly. In order to check the low income and elderly population around the proposed bus line, two demographic layers (“Median Household Income” and “Population with Age over 60”) were added to the map. Users can see the new layers by clicking the check boxes at the bottom of the left column.
The new demographic layers tell that elderly population and low income households are not so high in the area. Therefore, to facilitate their usages, we need to consider giving incentives, such as discount pass…etc.
