The Switch writer, Caitlin Dewey, reviewed a recent study on Twitter in her article on “Where do Twitter trends start? Try Cincinnati” for the Washington Post. It summarizes a study done at Indiana University on where Twitter topics trend and spread. It found that Twitter trends that start in Cincinnati tend to spread out and reach other cities more than would have been thought for a city of that size. It concluded that physical geography has an impact on social media, which is often popularly thought of as transcending geographic location, by everyone but geographers and geospatial scientists – or do they? It turns out that The Geography of Twitter is a trending topic itself in the research world. Continue reading
A few years ago, I ran across a fun website, called Be My Satellite, which promotes geoliteracy through collaborative satellite image-hacking. It is a type of large scale art installment that uses the spatial pixel grid as a creative tool, typically for Google satellite views. Another type of satellite art uses prints of images cut from Google Satellite View, Jenny Odell is a well known artist in this medium. Google Earth has generated many new types of art and revived others. Google Earth Art blog asks if Google Earth is the inspiration that revival landscape painting needs. Other artists and photographers, such as Mishka Henner featured in DPReview are creating open-source art from Google Earth images that provide new perspective about life on Earth – much like geospatial analysis. While in late October, Clyde Space and iam8bit is releasing an Andy Warhol-inspired satellite created by artists Jon Gibson and Amanda White into space, making it the first space art installment.
Therefore, when a local artist told me that she had been experimenting with large scale art that you can only view from the air, I got excited. I told her that she was talking about geo-spatial art and that it was an actual movement in the art world. I was able to discuss geographic information science, remote sensing, satellites, NASA, Google, and the crossover of geospatial technologies and art. It is always enjoyable when the topics that you like discussing and those that a friend enjoy discussing coincide – no matter how seemingly esoteric. The next step is to use one of the many satellite trackers to identify a potential satellite and ArcGIS to mock up the installation. The hard part will be the attempts to align the two up just right – which makes art and geospatial technologies a challenge.
According to NPR, when the newly completed San Francisco Bay Bridge reopened, “There was little fanfare, but the gleaming white and newly built $6.4-billion eastern span of the San Francisco-Oakland Bay Bridge reopened to the public as vehicles began crossing it after more than a decade of construction delays”. This lack of fanfare is surprising because for the past several years the Bay Bridge has been an ubiquitously geo-spatially explored bridge construction project owing to its proximity to innovative government, company, and residents and its importance in their lives. It is also the World’s Largest Self-Anchored Suspension Bridge.
To list a few spatial projects from over the years:
EarthCam released a time-lapse video of six years of construction on the bridge.
- Bay Bridge Photo Documentation of the past 15 years of construction by photographer Joe Bloom (1998)
- Bridge to Classroom, an interactive bridge building educational site based on the Bay Bridge by NewBayBridge.org (2006)
- Bay Bridge 3D Images on Google Earth, a cooperative project between CAlTrans and Google. (2007)
- Bay Bridge Time Lapse Video by EarthCam of six years of construction on the bridge (2008)
- William Gibson’s Bridge City proposal for the old Bay Bridge by Ronald Rael and Virginia San Fratello (2009)
- Bay Bridge Explorer, 3D iPad video game in collaboration with AutoDesk (2011)
- Bay Bridge Construction Cams, San Francisco-Oakland Bay Bridge Seismic Safety Projects (2012)
My day was made brighter this morning by a Paris Metro Project by Hwan Lee, which is an Art Takes Paris project that details all 261 metro stations in Paris and the path of Hwan’s walking history. I know that it is an art exhibit and that it is an actual static map, but wouldn’t it be wonderful if interactive maps were so artistic. Frank LaFone and I have often discussed the need for artists to get involved in the geospatial process. It takes a certain eye to create a useful and aesthetically pleasing map. One that was either taught or engrained in many cartographers in the past. As the line of viewer’s at the ESRI Map Gallery and the People’s Choice Award Winner illustrates, art and maps create an enticing combination of human expression. Continue reading
We downloaded several apps for our Very Spatial Road Trip that were recommended by friends, online reviews, and VerySpatial podcasts. Since she was acting as navigator, Barbara insisted on stopping at AAA and picking up a stack of paper maps for back up. We found that there is no better crucible for road testing a travel app than a lengthy trip into the unknown under sometimes stressful and time imperative conditions. We felt like the explorers in Dava Sobel‘s book “Longitude” who were sent to sea with new technologies that we hoped would live up to their claims. It wasn’t until after our trip that we heard more honest opinions on the strengths and weaknesses of the apps we packed. A friend, who is a global traveler, told us that it is good travel etiquette to leave our own input on any crowd-sourced apps as our “payment” for using it and to “pass it on” to other travelers. In that spirit, we have written a review of the apps that we used on our road trip from WV to CA.
Day 2 we hit some fantastic spots around St. Louis. Hit the link below to find out more!
According to a discussion in my LinkdIn ESRI Network, The Driving Dutchman of Cyclomedia is on the last leg of his roadtrip across America to the San Diego ESRI UC. Their mission statement has a cool picture of their professional vehicle and a description of how they capture street imagery. They are requesting drive bys and demonstrations from organizations working with maps.
The BBC News Science & Environment section has an article on “The Secret Life of the cat: What do our feline companions get up to?” with an interactive map of cats in a Surrey Village. It was created by BBC Two’s Horizon Program and researchers at the Royal Veterinary College. It is based on a study by Dr. Alan Wilson, an animal movement specialist, at the Structure & Motion Laboratory at the Royal Veterinary College. In his article, “Secret Life of the Cat: The Science of Tracking Our Pets“, he provides information on the technical challenges of using GPS to track domestic cats. Like many scientists working in the field, Dr. Wilson has had to develop his own tracking equipment in order to study the movement of pigeons, sheep, cheetahs, wild dogs, and of course, cats. He is currently working on developing unmanned arial vehicles for remote sensing and movement tracking. Cats are a great way to introduce the public to interactive mapping, tracking, and geospatial concepts because cats and birds are the most popular pets in the world.
The combination of cat popularity and GPS even resulted in a best selling book, “Lost Cat: A True Story of Love, Desperation, and GPS Technology” about a writer’s determination to find out what her cat did when he went off into the “wild”. CNET has a good video, “Using GPS to Track Exactly Where Cats Creep“, about how the authors learned to track Tibi. The convoluted way they had to map his tracks illustrates the need for education on using GIS or an easy to use cat GIS, to go along with the easy to use cat tracking GPS market.
Recently, I have been developing a tutorial for using electronic white boards for education. What I never noticed before, because they work so well together, is the symbiotic relationship between the use of electronic white boards and geospatial technologies. In an ENO by Polyvision demonstration, today’s modern classroom (of 4 years ago) includes a Google Earth based geography lesson. Other demonstrations include the use of Google Sketchup on an Eno Board. A short video from Bayside Secondary in Ontario demonstrates the geography classroom of today using iPad apps and a Smartboard in a geography exercise. Interactive white boards are a natural fit for geography because of the creation of interactive wall maps by many former static map publishers, such as those developed by KIDS Interactive or StrataLogica NECC. According to ESRI’s educational model for building geospatial proficiency, presentation is the first rung in developing geospatial literacy. A conference paper on the “Place of the interactive whiteboard in higher education of the Polish educational system” specifically discusses its use in teaching GIS and spatial literacy.
However, the integration of geography, GIS, and electronic whiteboards doesn’t stop at K-12 education. At the GIS Conference 2012: Logica/CGI demonstrate their collaboration between ArcGIS and SMART Board that can be used with ArcGIS Online. The Montgomery County Emergency Management Agency in Tennessee likes to use a a Smartboard in conjunction with their GIS, in order to all be “on the same page”. I think I am so used to thinking of collaborative GIS as being done on a horizontal touch screen or table top device, like the TouchTable, weTable, and other multi-touch environments, that I overlooked the power of the humble interactive white board.
