My Google CTA Map
I totally thought I mentioned this but I guess I completely forgot. Anyway, back in July of this year I put together a Google Map of the Chicago Transit Authority's (CTA) elevated ("L") tracks. You can check the map out at http://www.tastypopsicle.com/maps/cta.asp. It was a long process to plot out all of the points to accurately trace the tracks and not just to connect the dots of the different stations. On the right side you can select individual stations and you can even show/hide particular lines (just click on the colored line's name at the top of the screen).
After you click on a station, either from the list on the right or from the map itself, an info window pops up above it. You can click the colored line's name from the info window to get the CTA's official schedule for the station and you can even use the select list to find certain business around the track using Google Local.
It was a great way for me to get comfortable with using Google Maps. And I did have some fun making it. Let me know what you think of it and what else would you like to see it do. Maybe I can work on it after the wedding.
eNjoy!
Right now I'm feelin' - good natured

Why I'm even mentioning this now. ed knittel
I've gotten some stray hits over the last couple of months from some places. Mostly at first it was from the Google Maps discussion group. But now others have picked up on it and it's been mentioned in a few places:
It's also mentioned in a few other places, but usually just as another item in a list of other Google Maps. For example, GIS-Lab in Russia (?) mentioned it back on August 3. This Google Search shows a bit more.
- I got a dig from Digg.com 3 days ago
- Google Maps Mania saw it on Digg and linked to my map
- Sunnie Land mentioned it today (is that Japanese?)
- Wingo added the map to their Google Maps API Examples list awhile back
- Adrian Holovaty made the "first" Google CTA map. It used a Firefox script to overlay the CTA's map onto Google Maps. It didn't use the API but it's what inspired me. It now appears that on September 26, Steven Vance mentioned my map in the comments.

Now, when you hover over a station it's name pops up and to the right. It definitely helps to clarify things even more.

Neat Desco
Pretty cool, but the map is only allowed to take up 50% of the browser window, so it's kinda small. I like the proportions of Google Maps, so if you could make the list of stops feel more like a sidebar rather than half the page, it'd rock. Plus your server's kinda slow, so while the map itself updates fast, the station locations and lines take a while to refresh.
Oh and you've got the Forest Park station in the wrong place-- you've got it going all the way to Madison St, when it should be at Des Plaines and Van Buren. It's official address is 711 Desplaines Ave., Forest Park, IL.

Thanks for the input, Desco ed knittel
The unfortunate part of any good Chicago Transit Authority "L" map is that it is a much more vertical map (taller) than it is a horizontal map (widder). Yet, all monitors favor width over height (my 17" NEC monitor has a screen real estate of 33.7cm wide and only 27cm high). My goal with the map was to include all of the CTA stops on the map when it initially loads - which I was able to do. Many other CTA Google maps fail to deliver in that way. I originally thought about having the list of station names load into a scrollable div but it really looked fugly and it loaded a horizontal scrollbar for no reason. When I say it looked bad I mean it looked bad. However, I'll look into ways of improving the display. I do agree that there is more that could be done with it.
And talk about slow sserver - when I try to hit up the CTA's website all I get is
"The operation timed out when attempting to contact www.transitchicago.com" Well, even though it takes 12 seconds at least mine loads. (I'll look into the Forest Park deal when the CTA has their site back up - and on second look, my whole Blue Line looks to be messed up or something)

CTA map updated with corrected Blue Line route ed knittel
My Blue Line data was WAY off. Like, so far off at some points it was borderline retarded. It also suffered from my forgetfulness to accurately trace the outline of the train route along the tracks. So, I am now happy to report that the Blue Line stations have been accurately plotted as well as the route between the stops.
A special note to those who may observe: the route does not match up with the "Map" mode of Google Maps. It does, however, match with either "Satellite" or "Hybrid". You can blame that on Google for not having their maps match up exactly.

Chris - WOW! I completely missed that. Well, actually, in all fairness I did have Sedgwick listed for my poly line points. I just didn't list it in my main cta.xml file (oops!).
Anyway, not only have I added Sedgwick, I also cleaned up the Brown Line train line so it follows the tracks just like ALL of the other lines do and have done (I live on the Brown Line - I have no excuse for my laziness).
At any rate, I belive my CTA Rail map is now complete (don't expect a CTA Bus map any time soon).

Hey... First of all - this is awesome...
I have some questions!
- Is there anything you can do to reduce load time? It's craaaaazy slow for me.
- Any chance you'd be willing to share the polylines and whatnot that plot out the CTA train system?
- Any chance you'll be adding the Metra rail? I might be up for it, if I had some guidance on how you did this...
If you really want some self-torture, how about the bus routes too! Har har ;-)
Seriously, this is totally awesome... I have a very useful application for google maps that I'm developing (well, it's done, but only for a much smaller community than Chicago), and I would really love to integrate train routes into it... (or in that small community, bus routes...)

Steve, feel free to contact me ed knittel
Use the contact me form to get started. My cta.xml file and all polyline xml files (ther's one each for each train line) are available for anyone to use. Just be sure to credit back to me if you use them. You can find all of the files listed if you view the source of the cta map page. I'll get around to budling it all up at some point but not today.
As to your questions: there is nothing I can do about the load time without compromising my solution. If I was only loading the train stations than it would load very quickly. However, I have chosen to load all of the train lines as well as the stations. On top of that, I'm actually loading the train lines twice: once for the color and a second time to outline the paths with black to help them pop out more. Becuase the train tracks are curved there are a lot of polypoints that need to be plotted to make it look smooth.
As for the Metra and Bus lines - well, I invite others, like yourself, to take a stab at them. Personally, I don't take Metra or the buses but I do take the L which is why I chose it as my first Google Maps project.
Really, what I'd like to do is also do a CTA Yahoo! map but that hasn't gotten too far yet.

Awesome and very usable GM hack! CTA could so use this on their web site. The only thing that could improve it would be the ability to plot directions from a station to an address, or even find the nearest station to an address. But, in general, getting around on CTA just got much easier!

Directions From CTA station joe
A very useful addition would be directions from a CTA station to the place you want to go to. Your map is useful, but still not that useful if I can't see which station is closest to where I want to go. Just having a marker of where you want to go would be useful to gauge what is the closest CTA station.

Joe: I really wish I could ed knittel
Anyone willing to lend me a hand (or code) to be able to successfully add a marker to the map based on an inputed address would get their name added to the Tastypopsicle CTA Google Map Project™ I'll be honest, though, adding directions to/from a CTA station will not work as Google does not have that currently available in their API. Sure, I/someone could hack/mash/create-a-hodgepodge of funtionality to do this, but it breaks the license agreement with Google. Also, Google's directions are designed for drivers, not walkers. So, while it's ok for a walker to head in the wrong direction on a one way street, obviously it's illegal for a driver to do that. So, the directions wouldn't be useful I'm afraid. And then people would bitch to me about that. And I don't like being bitched at.

How did you create your Station Icon images? Rob
Hi Ed,
I am working on subway maps for other cities, and would like to create images just like the ones you have (for example: mm_12_circle_blue.png) to identify each station only using different colors. Can you share how you created them? I tried to mimic the images exactly in Photoshop and I got really close (using the text tool, create a period "." that is 105pt Times New Roman and apply a 1px stroke, position inside) but it is not exact.
Thanks,

I agree that it would be really sweet to have the map overlayed at maps.google.com. With that said, I don't even know where to start. I know Holovaty did some greasemonkey stuff by overlaying images of the CTA's map on top of the maps.google.com. I suppose that would be as good a place as any to look if I wanted to do this. But, as I have mentioned in the past, my files are free to use by ANYONE who wishes to enhance/improve/mash-up what I've started.
I think that just having the data points out there is beneficial to anyone who's looking to integrate the CTA's El lines into their project. So, Andreas, if you know anything about creating greasemonkey scripts I'd love to see what you can do with my data. Let me know if you do something as I would love to see it.

still not in the right place. Scott Marlowe
Are you sure you moved the data point for the right belmont stop? The one on the blue line is still showing as being on I-90/I-94 on my map. The Addison stop is the first one that's in the middle of I-90/I-94.
The belmont stop is below ground, and the blue line comes up above ground at the addison stop. Here's the above / below listing for the blue line:
On the south / western lines (54th/Cermack and the Forest Park branches) they're both above ground until after they meet, and at the racine station. It then goes underground at the UIC-Halsted station, and stays underground through downtown, and through the Grand, Chicago, and Division stations. Then, it goes back up above ground for the Damon, Western, and California stations, then goes underground for the Logan Square and Belmont stations, and comes back up at the Addison station and stays above ground all the way to O'Hare.
By the way, there's a new line coming. The 54/Cremack branch of the Blue line will, during rush hour, continue north instead of turning east where it currently intersects the Forest Park branch, and will then go into downtown on a new set of tracks, above ground the whole way. I'm not sure when this is going to be happening, but they've refurbished a section of track that's lain dormant for over 20 years to do this. Let's hope it works out.
Oh, and finally, for CTA Chicago on google, your site is number 2! woot! great work.

As for the "Pink" line - yea, I'm familiar with the current details. I have most of the map ready to go when the change happens in June. However, there remain a lot of unanswered questions from the CTA that I need to wait on.
But, when the CTA is ready my Google Map will be ready.

Scott, you made me do it! I just took the last 40 minutes or so and put together what I *think* the plan for the Pink line is. From what I've read, the Blue Line will still be going down to 54/Cermak during rush hour times (kinda like the Purple I guess)
Anyway, here's a sneak peak at what the CTA Google Map will probably look like come June 25.
eNjoy!
Starting June 25, Cermak trains will no longer join the Forest Park branch at the Eisenhower Expressway and run through the Loop via the subway. Instead, they will head north along the Paulina Connector and join the Green Line, running east into the Loop on elevated tracks. Some rush-hour trains, however, will continue on the old route.so all of it's stations will be shared with other lines - even through the Loop.
Anyway, here's a sneak peak at what the CTA Google Map will probably look like come June 25.
eNjoy!

I'm sorry but I have no plans to add METRA to my CTA map. However, my data is freely available and I know that someone else has already made a METRA map. Anyone can combine all that data into one. So I wish you the best of luck!

Excellent Map! Andy Fischoff
This is really a fantastic tool which you've made - great job! I do have to ask if there is a way to search for an address (as you normally would with Google maps) but continue to have your map overlayed? That would really be helpful to me being in Real Estate investing/sales. Thanks so much.

A few quick comments Dan
First... On my display at least, the Purple and Pink Lines in your Pink Line preview look a bit too similar in color.
Second... Things get a little confusing in the Loop due to the overlapping polylines. The Green Line disappears completely downtown, unless you're zoomed out far enough to see it re-emerge from underneath the Orange Line to the south. Have you given any thought to rejiggering your common lines to run side-by-side? (Granted, things might get a bit cramped on the north and east edges of the Loop and the lines would probably fall too far apart when zoomed in all the way, but couldn't you optimize it for, say, zoom level 3 and let everything otherwise fall where it may?)
Third... Is there any way you could limit the redrawing of polylines to the current extent? Panning is painfully slow, and it seems to be spending that time unnecessarily redrawing all sorts of stuff offscreen.
Fourth... The Purple Line stops at Wellington and Diversey.

I've switched on the Pink Line ed knittel
I read over Dan's comments and added the Purple line stop at Wellington and Diversey. These were already indicated in my points_Pu.xml but I overlooked them in my cta.xml file. Thanks for pointing that out.
At the same time I decided to switch the map to show the Pink Line as I'm sure it will be pretty important to see for some visitors now. However, I haven't tried the links to station schedules so there may need to be some tweaks. If you see anything odd let me know and I'll look to make any corrections.
As for Dan's comments about the overlapping and confusing polylines in the Loop area, this was a concious decision as polylines next to each other will require even MORE data points which would be inaccurate to begin with. My map has always had the ability to show all lines or to show just a single colored line. If you are only interested in the Orange line then click on the Show Orange Line link at the top of the page.
Hopefully that should help. Thanks for your comments and keep them coming.

Many thanks Jim from South Dakota
I looked at several maps of Chicago before I found yours. When I get off a train or subway, I want to know exactly where the streets are in relation to the train. The CTA website doesn't show this detail. We travel a lot, and try to use public transit as much as we can. We are flying in to Midway and staying in Chinatown, so I wanted to know how to get from the CTA to the hotel, and your site showed the path. Chicago is a great city, and you are providing a great service.

Konqueror Ken Bloom
Your CTA map doesn't work on Konqueror (the browser that's part of KDE for Linux). I wouldn't even begin to be able to tell you why, but it just shows "Loading map... please wait" and "Loading stations... please wait" but never loads them.

Ken - it's Google's fault ed knittel
Based on what I read at http://whocares.de/archive/001064.php
I found that Google Maps won't display at all when using Konqueror under Linux. That's because Google Map's Javascript sports a function called IsCompatibleBrowser() which doesn't know about Konqueror at all. Thus the main Javascript script is never sent to the browser. To fix this, just tell Konqueror to send an alternative identification to the site in question. In my case using Safari 1.2.4 on Mac OS X did the trick. Unfortunately you have to do this for every site that's using Google Maps. Defining an alternate browser string for maps.google.com won't do.So, yea it's not just my Google Map, but I do appreciate the info. If it's any consoltation, the kids at Slashdot are unhappy as well

Google transit! Steve
Have you seen Google Transit?
You should submit the data you have to google transit's project. Basically, it's like the RTA Trip Planner, but much better. Currently it only exists for Portland, but they're willing to work with people to get it going for other cities and will accept data in just about any format you send to them.
It's at: http://www.google.com/transit
I'd love to see it happen, and might be willing to help out.. the rough part would be figuring out all the CTA Bus stops.. then adding in Metra... yikes. Still would be great to see @ Google though!

Recent Problems in Camino Scott Frazer
Up until very recently, your map worked great in Camino (a firefox 1.5 derivative under Mac OS X) but now the lines aren't drawing properly between the stations, especially when searching or scrolling.
Seems to work fine under Firefox 2.0 / Mac OS X though.

Recent Problems in Camino, et al. ed knittel
Scott,I downloaded and installed Camino v 1.0.3 (2006091101) and I can confirm that there is something weird going on when you start to zoom in. The polylines get all messed up. They start being redrawn every which way. At this point I'd have to do some research into what is causing this.
Additionally, the "polyline problem" doesn't seem to be isolated to Camino. I have seen where after zooming in using both Firefox and IE that some of the train line polylines do not get redrawn. It seems random and inconsistent so, again, I'm going to have to do some more research into this.
Thanks for brining it to my attention... and Camino's not such a bad browser really. tastypopsicle.com looks great in it thankfully

Printing ability? Derrick W
I can't tell you how many times Ive used your CTA google map for getting me to the proper CTA stops. I go to school at DePaul university in Chicago and this map site rocks! I like the updates you have put in especially the address pinpointing feature. I used to have to simultaneously zoom in on your CTA google map and the real google maps in order to find my stop by using matching lol but not anymore.
One feature I would like to request is the ability to print. Right now I can just screenshot the map and print it from Irfanview, but for times when Im not at home or on my laptop, this would be nice. Dont know if Google Maps provides API access to such an ability, but if so, wow this would be wonderful. Just a thought... and an email response would be nice :D

Spurred on by Derrick's comment from yesterday I spent about 25 minutes this morning and I made some changes to the CTA Google Map to enable printing. Due to the limitations of PNG printing support in Firefox the train lines do not print in Firefox. Surprisingly, the best browser to use with my CTA Google Map is IE. Sorry.

I love the site and plan to use it often--thanks so much! However, as a software tester, I feel compelled to report this bug: in my FireFox browser, if I don't have the window maximized, the address edit box will disappear underneath the map. Works fine in IE, however (I hate to have to say that!).
Also, can you post or e-mail me an address where I donate some moolah to the cause without having to open a PayPal account?

Re: What a great and nice app!!! ed knittel
Mr. Captain Way,
As you probably noticed my map enables you to place a marker for any address onto the map. It serves as a great reference to see what train station is the closest and what is likely the best route to get to the station. When I originally created the map I needed a way to handle the address passed in the query string. And since I have been programming VBscript for 8 years I naturally chose that route over PHP or any other language.
However, I recently discovered that it's possible to extract information from the query string through Javascript. So as my CTA Google Map currently stands it's 100% server side programming free. It's just HTML, XML, and Javascript. Hope that helps.

As for a Metra equivalent - I have no plans to make one. I've been asked about it multiple times but I just don't have a burning desire (no offense) to the suburban train lines like I do for the CTA. I have made the Javascript code VERY easy to understand (do a View Source) and all of the XML for the train lines is available for anyone that wants to take a hand at the Metra. If you have the coordinates of each station it would be trivial to create similar map. Others have tried but I haven't seen one made to the level of my CTA Google Map.

re: Shared Web Hosting
by the way, there's a new line coming. The 54/Cremack branch of the Blue line will, during rush hour, continue north instead of turning east where it currently intersects the Forest Park branch, and will then go into downtown on a new set of tracks, above ground the whole way. I'm not sure when this is going to be happening, but they've refurbished a section of track that's lain dormant for over 20 years to do this. Let's hope it works out.
