A project I worked on for a digital zine Elia Vargas is putting together. I also submitted this to a call for entries for the Istanbul Biennial, which was announced by Stamen Design. You may view the live / interactive version here.

Culture Code Cities Cells

In the last several decades cultural production has shifted from being shaped primarily by geographically separate places to a world that has become continually influenced by interconnected networks. The pivotal factor being that mobile devices and the web now mediate how many people experience their lives. In response, the data generated from these devices and shared across the web are informing how users of the technology view the world from their constant connectivity to email, social media and instant messaging. Thus we may choose to work from about any location at any time. We learn about events as they are unfolding. Time is now experienced in milliseconds rather than large hourly blocks (what’s on my Twitter feed vs. how has the news progressed since last evening?)

In this map the shape of the continents has been created from geotagged photos on Flickr. Nations and states / provinces are shown as Voronoi cells, also generated from Flickr user data (in a given place do Flickr users think it’s administrative area A or B?) Ten minutes of geotagged tweets collected on September 4th are shown in their temporal sequence that contrast with standard time zones which highlight on a mouseover. This map is an attempt to ask if we should rethink how we define time and place. Just as time was standardized following the advent of telecommunications and the rail roads, our computerized networks suggest the future of time is not what it used to be.

Recently at my internship with CartoDB I’ve been helping test and document a new open-source tool called Odyssey which makes it easy for anyone to tell stories with maps. For part of the testing process I created an example story based on Darwin’s Voyage. The content comes from this Wikipedia article and the latitude & longitude coordinates for each location are from GeoHack. Odyssey makes it super easy to publish your work either through a link to a full page view, an iframe embed or by downloading the html, css, and js files to publish on your own server. I’m really looking forward to seeing what kinds of stories people will tell using this tool! Here is a link to the full story I created.

Guess That NYC ‘Hood from Chris Henrick on Vimeo.

An in progress NYC neighborhood guessing game for the web that runs on Node JS via the Express framework and MongoDB with Leaflet JS, GeoJSON and Underscore JS. This was my final for Web 3: Javascript last semester, taught by Mani Nilchiani. The user navigates a map of New York City and selects neighborhoods that come from a dataset by PediaCities. Their guesses are checked against the neighborhood boundary data and then stored in a NoSQL database (MongoDB). If the guess is correct then the polygon for that neighborhood disappears from the map and they are color coded blue in the left part of the interface.

I’d like to make the game two player using web sockets so players could compete against one another, as well as add a timer to give a sense of urgency. There is also the possibility of making this game more in depth conceptually such as providing historical information about the neighborhood being guessed as commentary on gentrification in NYC.

Code for the project is available on GitHub.

 

So after a lot of work I’ve arrived at the second major update for my Major Studio Two project which tells the story of my brother Mike’s thru-hike on the Pacific Crest National Scenic Trail through an interactive web media experience.

Major milestones include:

1. Debugging a Leaflet map interaction where the animated marker (representing my brother’s position) triggers popups to open on the stationary markers.

2. Improving the interaction between scrolling and the animated marker start and stop using the JQuery Waypoint library. Now when the user scrolls, then animated marker will only start and stop when the user passes the correct chapter chronologically. I found that users tend to scroll up and down through the site fairly quickly to get an idea of long it is. Previously this would have caused the animated marker interaction to be buggy.

3. I’ve also managed to do some user testing for the site today which has proven to be super helpful. I will admit that all the folks that have helped me out have been DT students so I will also test the site with some people outside of my program for a different perspective. Here’s some feedback I’ve received so far:

1. The title bar doesn’t stand out enough and blends in with the rest of the site too much. The url of the site would also help with the title (no url as of yet…)

2. The Alan Watts quote on the opening slide is hard to read; try masking the area behind it with a transparent fill. (fixed)

3. Initially the user has no idea who the main character is. It would be helpful to add some background about Mike and the PCT in general prior to the start of his story.

4. The map transition from overview to the start of the trail should be slightly smoother and more seamless.

5. It’s somewhat confusing where the marker is going in relation to the content. Some suggestions to improve this are to break up each chapter’s path so that the marker will travel shorter distances. Then have photos or other text blocks trigger the marker to move. This would also help connect the particulars of the content with the map. Text blocks could even be highlighted so that when the user hovers or clicks on them their location is displayed in the map. Another suggestion was to repeat each chapter title over the top of the map so that the user is aware of the connection between the area being traveled and the map chapter.

6. When the marker is moving the map tends to shake. I’m not sure if this is something I have a lot of control over but will definitely think about.

7. Add a locator map to show the regional overview (ie: the current state or entire trail) so that the user has an idea of where on the whole trail Mike is.

8. Use Lazy Loading JQuery library to load the images as the user scrolls. This will help cut down on overall loading time and improve performance of the site.

9. Possibly consider adding menu options to the title bar so that the user can jump to certain chapters. This will be somewhat tricky to implement but may be necessary. Also adding forwards and backwards arrows could be helpful with navigating chapters. Worth testing though.

Positive feedback I recieved was that the site is very readable and would make a good narrative template overall. The first image is liked by everyone I’ve tested and serves as a good introductory slide.

Lastly, some updates from a house keeping perspective are to make the site cross-browser compatible (right now I’ve only been developing it using Google’s Chrome browser) and organizing the javascript code into separate modules / files.

Looks like some more updates and then another round of user testing will be needed. Looking forward to completing this project and submitting it to the student mapping competition for NACIS this year in Pittsburg, PA.

 

Triggering PopUps with an AnimatedMarker in Leaflet JS from Chris Henrick on Vimeo.

With the help of my web-developer guru friend Eric Brelsford, I’ve managed to figure out one of the last pieces of my Map Story project which was having the animated marker on the map open popups on stationary markers that represent points of interests, natural features, towns, etc. I’ve documented the code in a GitHub Gist which can be viewed live on this block. Excited to be wrapping this project up soon (hopefully!).
