Quest for Station Entrance Data
I have figured out how to more accurately represent stations, by including each stations entrance. My simple approach is to just plot each stations entrance as a marker of the station.
The tricky part is getting the location data for each station entrance. I’m hoping I will not have to go through and manually figure out the geocoordinates for each station entrance, but because wmetro.com doesn’t provide accurate entrance information it appears I will be forced to go through this process manually 
If anyone has any suggestions about how to get this data, I’d love to find out otherwise it looks like over the next month or so I’ll be building this data manually.
Since, I’m a frequent user of Farragut West, I figured that station out and you’ll notice it appears on the map now twice, since it has two entrances. The search algorithm handles this correctly, so if you search for the nearest station to “1590 I St. NW, Washington, DC” for example you’ll get Farragut West now instead of Farragut North. Now that may change again once I finish plotting the alternate entrances to Farragut North, but for now it’s at least more accurate then before.
