Factory Farm Web Map for the U.S.


Hogs

U.S. Census data are used to create this web map showing factory farms in the U.S. In the image above you can see where hog farming is prevalent. The site gives loads of information on how these farms - chickens, cattle and pigs - impact our environment, our food security, the affects on the animals and on our health.

This is a project of Food & Water Watch.

The President's Speech and Thoughts on Paying for Innovation #SOTU


Obamasotu

President Obama's State of the Union address on Tuesday night had several aspects that should be of interest to educators, scientists and technologists. Readers of this blog, most typically GIS and geospatial specialists, should take heart in some of the ideas brought forward by the President.  Though Obama stressed innovation in fuel and medical technologies, and I will not hypothesize on what Winning the Future might mean, I argue that strength in all areas of technology and innovation will be critical for the nation's future on the global front. 

Some highlights from Obama's speech:
We'll invest in biomedical research, information technology, and especially clean energy technology - an investment that will strengthen our security, protect our planet, and create countless new jobs for our people.

and

That's what Americans have done for over 200 years: reinvented ourselves. And to spur on more success stories like the Allen Brothers, we've begun to reinvent our energy policy. We're not just handing out money. We're issuing a challenge. We're telling America's scientists and engineers that if they assemble teams of the best minds in their fields, and focus on the hardest problems in clean energy, we'll fund the Apollo projects of our time.

We need to get behind this innovation. And to help pay for it, I'm asking Congress to eliminate the billions in taxpayer dollars we currently give to oil companies. I don't know if you've noticed, but they're doing just fine on their own. So instead of subsidizing yesterday's energy, let's invest in tomorrow's.

This sounds good and it appears to be a plea for an increase in innovative ideas. But when the President says "we're not just handing out money," I fear that that may be exactly what is done. How will the President go about encouraging America's "scientists and engineers" to "innovate"? 

We have to out-innovate, out-educate and out-build the rest of the world.

How? My thought is we need to work on the pipeline of young minds who will be doing the innovating. 

As Obama said, we are a nation of Google and Facebook, homegrown technologies that didn't sprout in a medical lab or an engineering school.  How do we cultivate in grades K to 12 and in colleges and universities more Sergey Brins, Mark Zuckerbergs, and Bill Gates when we do not place importance on teaching with, about and how to use technology? Though I usually feel government spending on education is sacrosanct, I think we need to tap the business sector more and seek more "innovative" technological funding ideas from all of the corporations that benefit from smart, technological young minds. I wrote my thoughts on this idea for an opinion piece in Educause Quarterly. Rather than rely on Uncle Sam to fix it and rather than expect Microsoft or Google to fix it, all areas of the private sector benefit from a technologically ready and capable workforce.

And one more thing, it must involve more than the scientists and engineers to work out the real problems we are facing right now, so let's spread around the responsibility.

I co-opted the above image from the White House's Flickr site.

FedEx and Cartograms

I'm not really sure why FedEx - delivers to a changing world - got into the map visualizations game, but take a look at some of the many cartograms of the world. Attached here are recycled paper use by country (largest is China), beer imports (the U.S. leads), and population density (largest Singapore). Click on See Other World Topics and check out the other maps that FedEx has put together. Some look goofy but it's still kind of fun to look at these maps.

Thanks to my friend geoparadigm for tweeting this.

Can You (Really) Map on an iPad?


Geologist


I wanted to find out whether anyone has figured out how to use an iPad to map with. I tried out an iPad (with 3G) a couple of months ago and used the Google Earth app, Google Maps app and ESRI's GIS app. With plenty of nearby cell service, I could find myself pretty accurately. Great! But I could not for the life of me figure out how to save a location and, thus, create a KML.

I put the question to a list that I'm on plus I sent out a call on Twitter.  Because I think information like this should be freed from the lock-box of email threads and Twitter streams, I am compiling my findings here. I should also say that I am a known skeptic when it comes to the iPad. My research was out of self-interest as I am writing a paper on using tablet PCs in field-based classes and I wanted to talk about alternative mapping technologies. (The geologist in the photo is using a Toughbook, just to confuse you/get your attention.) The reviewers of our paper did not believe me and my collaborators when we said that iPads were not a viable mapping option.

What do you think?

My question:
Dear NY GIS-users list:

I am collecting information on whether anyone has tried to use an iPad for data collection. Whether you tried and failed or tried and found success, I am most interested in use of the iPad for mapping. Can it be used for collecting and saving points, lines and polygons? Or if you do Google: placemarks, paths, and polygons?  Using the iPad's 3G capability, one can get a fairly accurate location when using ESRI's mapping app or Google Maps or Earth, but can one actually map location and saving and share as a shapefile or KML?

Many thanks,
Meg Stewart

Geospatial Instructional Technologist

Hi Meg,

I saw your question on the list serv and thought you might be interested in an app that we have developed, MobileRecon. Attached are two PDFs with additional info [Note: just look at the link]. There are actually new features in addition to what is in the brochures, so, if you're interested, let me know and I can detail those for you. While MobileRecon is built for iPhone, we have a version in the works for iPad that takes advantage of its larger surface area.

http://navagis.com/Mobile_Recon.php

Best, Jay
________

This summers On the Cutting Edge GIS and Remote Sensing workshop had a number of us exploring this. On one field day we had a mix of iPads, Toughbooks and Tablets running ArcPad, ArcMap and other software. Still working out best methods for mapping directly on the iPad, but a consensus was that this had real promise. I'll be exploring more this spring. We looked at using ESRI Arc on iPad, GoogleEarth and GoogleMaps and MotionX GPS HD.

Key points were,

-need cellular service to access imagery/servers in the field
-GPS was quite good in most cases (we were working in "good" environments)
-screen visibility was good, and in many cases much better than tablets
-iPad will not hold up like Toughbook, but does not cost $5000 either
-ziplock bag worked well to "weatherproof" iPad
-stylus needed to draw accurately

I'm currently testing BlueSLR app & hardware that links iPad and digital camera to encode GPS data in the EXIF data of digital photos.

Be really interested in hearing what others have to say on this.

Cheers,

Dave

Restored Map From 1770

Someone at the New York Times loves maps and stories about maps. Yesterday we got a glimpse of a lovingly restored map of the lower New York Harbor drawn in 1770 by cartographer Bernard Ratzer. Here is the Times story but you should really check out the interactive digital image of the map in it's "old" state and then again in the newly rehabilitated state (both shown here from the same location on either map). Check out the west bank of the Hudson River, in New Jersey. All of that swamp land has been filled in to make Hoboken and Jersey City and Ellis Island was called Bucking Island.

They don't make maps like that anymore.

Final Day of the Google Earth GSA Penrose #GEPenrose

From this past week of GSA Penrose Google Earth talks and posters, my head is swimming with ideas.  There were people here from all areas of expertise and from very different backgrounds. Most were geology professors, but there were some of us who are geospatial and/or educational technologists. There were course designers, academic press reps, and folks from funding agencies. I think there was so much enthusiasm at this conference that I do not believe this is the end of the conversation. It is the beginning.

Day 3 of the GSA Penrose Conference: Using a GigaPan #GEPenrose


Dsc00867

Yesterday (Jan 6) was a field trip day at the Penrose conference. Prior to taking off, however, we had an overview of the use and purpose on GigaPan panorama photographs from Ron Schott. You may recall, or at least this is how I first heard of GigaPan shots, the Obama Inauguration panorama photo. That was a GigaPan.


How GigaPan works is you use a digital camera, the higher the zoom number the better, the pixels aren’t as important as the zoom, and a motorized swivel head on a tripod. You set the camera up (using the GigaPan to control your digital camera) so that it takes a certain number of photographs sweeping from one side of the region you wish to pan to the other. This process can be short, say taking nine photos, to quite long, where you are taking hundreds of shots, all semi-overlapping. The photos are then stitched together in some sort of stitching software that blend the multiple images into one seamless panoramic photograph. GigaPan has a stitching software but there are others as well. Once the panorama is complete, you can zoom in very close, and depending on the configuration of the camera you use, you can see amazing detail.


Ron Schott showed a variety of ways he uses GigaPans in his geological teaching. He showed a rock hand sample (maybe fist-sized) that he could zoom in on small feldspar and hornblende crystals. Using these images could be more illuminating than using hand lens. GigaPan technology can be used with not only traditional microscopes but Scanning Electron Microscopes as well.



Gigapan


Use of GigaPan photos in Google Earth is fairly straightforward. In Google Earth under the Layers section and within the Gallery, click on the GigaPan layer and see what is available in the place you’re interested in. When you click on the GigaPan icon in Google Earth, you will fly “into” the panoramic photo and “see” in the spatial direction that the photographer took the GigaPan. Another resource for the GigaPan photos that are geo-located in Google Earth can be within the GigaPan web site. Look for the View in Google Earth link under the photograph. Or search for a place you’d like to look at in more detail.


Use of the GigaPan out in the field was not difficult. You do not necessarily need a fancy DSLR camera to take a pretty good panorama. Some people used their simple point and clicks. If you’re buying a GigaPan set up the motorized swivel head costs about $900 USD, get a digital camera with a large zoom range, buy lots of space on SD cards, and get a sturdy tripod. I hear that the processor on your laptop or desktop computer ought to be pretty souped up also.

Day 2 of the GSA Penrose Conference #GEPenrose








Today was another full day in Mountain View. I tweeted a lot. I've copied all hastagged tweets in below. I also gave a poster session later in the day (part of the above video) so I was not tweeting during that time. My interactive poster was on work based in the Grenadine Islands that I did last year while on my Fulbright.
