It’s fair to say we over at VerySpatial are big space nerds. And it’s fair to say we’re also pretty big remote sensing nerds. When the guys over at BoingBoing got to ask any question they wanted, they asked a pretty cool one about file compression (scroll down to see the answer). Sending images from Mars and back takes a bit of work and time, which means file compression has to be used. But we all know that we want as loss less file compression as possible, so what’s NASA to do? They turned to a custom implementation that uses a wavelet approach similar to Jpeg 2000. The difference in their compression is that it’s less computationally intensive, which means lower powered CPUs (both in computing and energy needs) can be used to create the compressed images. Pretty cool, huh?
After the ESRI User’s Conference Plenary, I began to think about the many fictional organizations that would benefit from using ArcGIS online and other GIS technologies. So I began compiling a top 10 list by asking other attendees, ESRI employees, and organizations at booths on the conference center floor. Which fictional organization do you think is in the most dire need of using ArcGIS online or GIS in general.
Top Ten Organizations that need to use ArcGIS online
1. Eureka!/Warehouse 13
The overwhelmingly number 1 suggestion, which is also the first one I thought of, is the parent organization that runs the town of Eureka and Warehouse 13. They are both awesome tv shows which showcase the power of science and technology, but they are desperately missing any form of GIS. Most of the problems they face fall into two categories: 1) Scientists didn’t realize that projects they were working on individually, usually within proximity of each other, would interact in a way that would spell DOOM., 2) Scientists didn’t realize that projects they have been working on individually could have been integrated and collaborated together to prevent The End of the World, until the very last minutes of the show. They could be a case study in why a large organization spread out over the world needs ArcGIS online.
2 – 4. The number 2 suggestions all fell into the realm of, all ethics aside…, because these organizations are not working towards the good of mankind, like all the organizations showcased in the ESRI plenary. Instead, they are organizations that could use ArcGIS online to make their nefarious organizations more effective.
2. District 9
3. The Hunger Games/ Panem Districts
4. Lost/ Dharma Initiative
5-6. These organizations and some not listed (Like the IMF from Mission Impossible) are intelligence related agencies that have a habit of losing people or things that lead to big problems. Cloud mapping or on-line mapping would be very useful to them to keep track of all of their differenct cells, groups, and projects.
5. The Bourne Legacy/ Operation Outcome
7. & 8. Daily Planet (Superman) /Daily Bugle (Spiderman). For internationally recognized newspapers of record, the Daily Planet and the Daily Bugle operate like old gumshoe type newspapers instead of the technology driven newsrooms of today’s modern media – news is location driven. They need to use ArcGIS online just to collaborate on stories about Superman and Spiderman alone. Speaking of which, wouldn’t the Justice League operate more effectively using it as well?
9. The Day After Tomorrow. There is a special place in the heart of scientists for the disaster movie The Day After Tomorrow because on one hand it is an enjoyable movie, but on the other hand, they got so much of the science wrong. They could have used ArcGIS online and ArcPad several times throughout the movie, especially when they would hold up a handheld device, look at a sky map, and declare – “I know where I’m going. The library is that way!”
10. Caddy Shack/ Bushwood Country Club . The top 10 fictional organization that needs ArcGIS Online is the Bushwood Country Club from Caddy Shack. There wouldn’t have been so many extra holes on the golf course, if they had used cloud computing to report any unusual gopher activity.
Honorable mentions: I would like to mention another two organizations that people mentioned could benefit from ArcGIS online or other product.
11. The Big Bang Theory/Harold Walowitz. It has been pointed out that Harold Walowitz spends a lot of time developing technology for space. It makes sense that he would be working with remote sensing.
12. Diablo III. Would there be a Diablo III video game if Cain was able to hold onto his knapsack that contained important information or if people could report finding Cain’s knapsack and uploading the location and his research. They could have analyzed it all via ArcGIS online and solved the game in half the time. Or maybe that is just my own frustration at being stuck on Level 11.
Do you have any suggestions for companies that could have benefited from using ArcGIS online or other GIS products?
Landsat, the moderate-resolution imagery satellite program that we all know and love, turns forty today. In 1972, Landsat 1 was launched with new technologies that along with its successors would lead the world, over the intervening years, to a better understanding of the environment, human impacts, and, perhaps most importantly today, human/environment interaction.
With access to the ever increasing spectral resolution through the MultiSpectral Sensor (MSS) and Thematic Mapper (TM) instrument packs we discovered, mapped, and used information about longterm, and short-term, change to reflect on everything from land use and land cover to soil moisture and water issues to viewing these multiband images and the landscape they represent as art. While the Landsat Program is not alone in these endeavors, it does deserve special recognition for its longevity, durability (Landsat 5, a workhorse even if it isn’t capturing TM data any longer), and initiative in leading many areas of the remote sensing/earth observation industry of today.
Perhaps most importantly, however, is its accessibility. From getting disks from EROS Data Center to recent initiatives that brought the referenced data online for download, the Landsat program has helped industry, researchers, teachers, and students all look at the world in a new way, often with a broader perspective.
Here’s to the Landsat Program’s first 40 years, and, with the much anticipated launch of the Landsat Data Continuity Mission (or simply Landsat 8) just around the corner in 2013, here is to many more years of moderate-resolution data to come.
Happy Birthday Landsat!
Europeans and Americans just give directions differently. Who knew? Researchers conducted an experiment to see if people gave directions differently if they thought the person was driving verses looking at a map. Turns out that while that does have an impact, where you’re from has a larger impact on how you describe directions. Americans tend to give directions by saying street names and giving cardinal directions, e.g. “Go North on Main St”. Europeans tend to give directions by saying the number of streets to go and whether to go left or right, e.g. “Go up two streets, then take a left”. The article proposes a number of theories as to why this might be the case, but they don’t actually test any of them fully. Still, it’s a pretty interesting finding, I think. Also, it’s yet another point suggesting that I’m secretly European and didn’t know it
Yard sale, garage sale, boot sale, trunk sale.. no matter what it is called, the idea of selling stuff someone doesn’t want out of their house isn’t something that is normally thought of as being geospatial. Yet, most yard sale pro’s think geospatially in terms of neighborhoods in order to get to the most yard sales in the short space of time they are open, usually from 8:00 a.m. – noon. It’s common to be asked at one yard sale, if anyone knows of any other yard sales on the same road. Jokingly, First for Women Magazine says that one of the “7 Signs that You’re Queen of the Yard Sale” is that ” 3. You’ve programmed the addresses of all the best houses into your GPS – and grouped them by neighborhood.” This isn’t your grandma’s yard sale planner using the often vague directions from the newspaper classifieds.
The Yard Sale Treasure Map is a free online geospatial tool created in 2009 that combines Google Maps and Craigslist to identify yard sales within a certain area. There are several Smart phone garage sale apps including gsalr.com which combines a garage sale locator with turn by turn directions. Garage Sale Finder is another app that makes it possible to download garage sale locations to your GPS. Some local community websites and newspapers, such as the Fredericksburg.com, Orlando Sentinel and the Town of Falmouth are providing online yard sale maps along with their classifieds listings. There is obviously a big market for geospatial tools that make getting to yard sales easier. If only there was some participatory GIS going on that would tell you the status of a yard sale. One of the big banes of yard sailing for everyone is when it closes early and there is no way to know not to stop by.
A year after the introductory post to my “All tied up” series I am actually releasing my next post. In the intervening year terms have, if anything, become even more interwoven with many of us often going to the now de facto ‘geospatial technologies’ to explain the wealth of technologies and data that we pull out of the toolbox and database for any given project. The term that has most been hidden by this (in my opinion, with no easy way to back it up) is Remote Sensing. By Remote Sensing I refer to what Lillesand and Keifer define as “The science and art of obtaining information…acquired by a device that is not in contact with the object…”.
This is a very broad definition and it captures all of the ways in which remotely sensed information is captured, but here I will narrow it down to those raster-based data (and occasionally point cloud data) that are captured from a distance. We can easily include photogrammetry (planes, balloons, etc) and satellite remote sensing capturing everything from panchromatic to hyperspectral images.
While we are on ‘what it is’ I will include what may get lumped in occasionally. Remote sensing is not all sensor data from remote locations. While the term is not incorrectly used, it is not always the same since some of these sensors are in direct contact with what they are measuring (stream gauges, temperature sensors, etc). So in a Venn diagram there is a large overlap between sensors located remotely and remote sensing instruments, but they are not completely overlapping sets. Kind of an aside, but I wanted to make a Venn diagram.
Getting back to remote sensing, there are two ways to look at the term. One is that it isn’t so much tied up, but largely absent in the industry today. In many areas, imagery has become the term of choice and, of course, the backdrop in our web maps, cartographic products, etc. In these projects and products we talk about imagery, but its source has become an almost unimportant aspect of some work. The other way we look at remote sensing is definitely one that is tied up in GIS. Many, many moons ago you had raster software and vector software and much of that raster geospatial software was driven by remote sensing activities, but that has changed (I think we can agree, for the better) in the GIS space as vector and raster has come together. As discussions with some of the leading remote sensing software vendors on the podcast have shown they are inline with, or even making tools available directly within, GIS software packages. We have lost the divide between GIS and Remote Sensing which having to switch between applications gave us. The separation continues to fade in terms of the software arena.
What does standout in terms of Remote Sensing, not tangled up if you will, is the hardware used to capture imagery (from satellite to helicopter to kite to drone…) and the data itself. This content continues to push our industry forward as we can collect both broad swath information that pushes science forward (e.g. moderate resolution data) and we continue to create sensors with ever-finer resolution and higher accuracy and precision (e.g. lidar). These data, as mentioned, are seen now more than ever with web maps and virtual globes, but it is the analytical potential that they offer, whether resulting in time series, human/environment processes, or finding archaeological sites, that are the strength of our investment in remote sensing platforms and data.
We will cut the strings there, as raster analysis is another set of terms that have been tied together as well. But keep in mind as you are doing your research or projects that your imagery is the result of over a century of research in capturing and manipulating images from a distance. While we have begun to take the technologies for granted in some cases, remote sensing remains an integral part of many areas of the industry.
I know I am about a week behind on this, but I am still pretty excited about TomTom’s ever growing utilization of its MapShare database. With the release of regular, free updates of the community provided information this brings not only a boon for the TomTom nav unit customers, but an increasing recognition of, and, I would assume in turn, an increase in community provided data. This is a great asset for the TomTom data licensing customers who benefit from these user driven data updates. (Yay!)
The great Ed Parsons giving Reuter’s the skinny on maps now and the future (the fine line between useful and creepy).
There’s a good 124 (ish) reasons I love this site – Building with Chrome and Lego. The most important are because it’s Lego and a Map. The basic premise is you can grab a plot of land and ‘build’ your lego construct virtually on that plot of land. It can be a house or an abstract sculpture or pretty much anything you can envision in Lego (except those weird Lego Bonicle things my nephew lovs so much). It is also great to see Google really pushing the envelope of what’s possible with Chrome and HTML 5. More ‘food for thought’ is a great thing for near future HTML 5 work that anyone involved in web stuff is going to have to embrace. My only real problem with the site is that even though it is tied to space, it is a space most people won’t know. The constructs are unlikely to represent Australian in any meaningful way. But hey, you can’t have everything!
Now if Lego would just move the experiment a tad South East and render all their Lord of The Rings Lego, we could recreate the movies in Lego on the map. Maybe that’s just too much awesome for one app
Every year, the gaming industry teases us with the latest and greatest in new games and technology at shows around the world. One of the biggest shows, E3 (Electronic Entertainment Expo) recently gave us a couple of previews that really wowed. The first, Watch Dogs, is by major game studio Ubisoft, and explores the implications of controlling all aspects of city functions, sensor networks, and even monitoring the inhabitants’ personal technology footprint through a single operating system, a “City OS”, and what would happen if someone had the skills to hack that system. The short preview of the game from E3 showcases stunning graphics and real-time movement, and shows that not only can the gaming world be a great source of inspiration and technology for geospatial applications of 3D and real-time modeling, but the stories played out in games can also explore the questions that arise from implementing this technology. Take a look at the preview here:
