Virtual Globes Symposium (email from Patrick Florance)

Hello,

I just wanted to make everyone aware of an upcoming symposium on VirtualGlobes in educational technology (i.e., Google Earth, NASA World Wind, ArcGIS Explorer, etc.). It's a really good group of speakers, and therewill even be a guest appearance by NITLE's very own celebrity Jon Caris of Smith College. Please feel free to circulate. The announcement follows.

Thank you,
Patrick

Will do, Patrick!

Registration is now open for NERCOMP's upcoming workshop:
*"VIRTUAL GLOBES: GIS 2.0"

DATE:
*January 19, 2007

*DESCRIPTION:*
Virtual Globes are being used increasingly by the news media; federal, state and local agencies; teachers; commercial agencies, and by people of all ages for personal use. A Virtual Globe is a three-dimensional software interface that allows users to observe and manipulate representations of the Earth or other worlds from a variety of views over the Internet. Users can often customize their own Virtual Globes by adding place makers or other geographic information such as satellite imagery, buildings, roads, demographics, etc. Virtual Globes have enormous potential for incorporating spatial information and spatial reasoning within a learning environment. A variety of Virtual Globe products and applications will be presented followed by a discussion ofthe various technologies.

For a full schedule and registration information, please go to:http://www.nercomp.org/events/event_single.aspx?id=643

*TIME:*
9:00- 3:15 (Coffee and Registration start at 8:00)

*PRICE:*
NERCOMP Members: $111, Non-Members: $211

*LOCATION:*
Southbridge Hotel & Conference Center Southbridge, MA.

More on Area Calculations

Remember when Keri wondered how to measure an area in her map?

Well, Kirsten wondered the same thing (what a concept...needing to know an area of a region in a map using GIS!! Why must it be difficult!?). She found an ArcScript called Graphic Measures (ArcMap 9) Worked like a charm. A separate window pops up and measures the length and area of the graphic that you've draw in your map. No need to make a shapefile.

What's Harvard Up To These Days?

Seems Harvard University dropped the Geography department back in 1948. Now, thanks to geospatial guru and Harvard grad, Jack Dangermond, they have a swanky new GIS lab.

Here's a snippet (but you should read the whole thing):

Hello, Geotech
"Modeling our world," geography returns to Harvard


by Christopher Reed


Take your geographic information system (GIS) for a spin around the block. It’s easy. Sit at your computer, which you have loaded with GIS software, and call up on the monitor a street map of Greater Boston. Superimpose on it a second map showing the household incomes of the citizenry. Those with the best dental work are in the suburbs, struggling scholars in Cambridge, the poor in the inner city. Add a third layer of census ethnicity information. All these data are public and readily available. Top it off with lines and dots showing Massachusetts Bay Transportation Authority bus routes and subway stations. Almost everyone is near a stop except in one big chunk of the city south of downtown. Your multilayered map will reveal to you what you might not have otherwise perceived, that the poorest, blackest Bostonians, in Roxbury and Dorchester, the ones least able to afford cars, are the least well served by public transportation.

And Finally...ESRI has released their Virtual Globe - ArcGIS Explorer



ESRI is pleased to announce that ArcGIS Explorer is now available for download. Use your ESRI Global Account to log in and download ArcGIS Explorer.

ArcGIS Explorer is a lightweight desktop client for ArcGIS Server, providing a way for you to publish ArcGIS Server capabilities within your organization or to anyone on the Web. ArcGIS Explorer is freely distributable and does not require any other ESRI software.
Using ArcGIS Explorer you can connect to content published by ESRI and others and fuse it with your own ArcGIS services or local data. You can create your own content or tasks for ArcGIS Explorer by authoring globes and tasks using ArcGIS Desktop, then publishing it to ArcGIS Explorer via ArcGIS Server.

Ready-to-Use Globe DataTo get started with ArcGIS Explorer, you can access a collection of ArcGIS Online globes including worldwide streets, terrain, boundaries and labels, political maps, physiography, and more. All of these are meant to form a foundation on which you can publish your own content. Once you have downloaded ArcGIS Explorer, you can connect to these via the ArcGIS Explorer Resource Center.

Centrally Managed TasksYou can use ArcGIS Server to publish custom tasks for ArcGIS Explorer. Tasks may include advanced geoprocessing and GIS analytic capabilities such as viewshed analysis, terrain profiling, and other ArcGIS Server functions without the need for programming. These tasks can be saved in specific maps for specific users, or they can be delivered independently. Because tasks are centrally managed on the server, once you make an update to a task, it's automatically propagated to all users that are connected to it.

Customizable and ConfigurableArcGIS Explorer can be customized to suit your preferences and needs by changing the startup globes and tasks which are available, changing the look and feel of the application, or authoring custom tasks.

ArcGIS Explorer also includes a software development kit (SDK) that can be used to extend tasks or can be used to implement completely custom tasks that are driven by other Web services.

A Breakdown of Virtual Globes and their Compatibilities with a Mac or a Windows Machine

"Ogle Earth" - 1 new article

Run ArcGIS Explorer on your Mac

Here's a fun GIS party trick: Run ArcGIS Explorer as an application inside Mac OS X. While you're at it, run SkylineGlobe as well: (Click on the image to enlarge)

parallels-small.jpg

No, they didn't just come out with Mac versions. Instead, Parallels came out with an update to its excellent Windows virtualization software for Mac. Two new features were added: The ability to run individual Windows applications just like any Mac application right in the OS X GUI, and the ability to use the Boot Camp partition with Parallels.

The first feature makes it look great, but what does the second feature mean? Apple already lets you boot into a separate partition on your Mac where you can run Window XP or Vista natively on the Intel Core Duo processor. Parallels, meanwhile, lets you create and run virtual disks with all kinds of Windows or Linux installs, and with virtually no speed penalty. With this latest update, Parallels now also lets you run your Boot Camp install from within Mac OS X, simultaneously. Before, you had to reboot if you wanted to use Boot Camp.

There is just one thing missing, still, in Parallels: 3D hardware acceleration. You do get full OpenGL and DirectX support in Boot Camp, so you can still reboot into it if you really want to access 3D functionality on your Mac, but that takes minutes. Parallels promises to add 3D hardware acceleration support in the coming months, but until then, here's a rundown of compatibility for the current set of virtual globes.

Mac OS X:
Google Earth: Yes
NASA World Wind: No, but Java version promised
Microsoft Virtual Earth 3D: No
SkylineGlobe: No, but Mac version is promised
ESRI ArcGIS Explorer: No

Windows via Parallels in Mac OS X:
Google Earth: Yes (no 3D acceleration)
NASA World Wind: No, only runs with 3D hardware support
Microsoft Virtual Earth 3D: No, only runs with 3D hardware support
SkylineGlobe: Yes (no 3D acceleration)
ESRI ArcGIS Explorer: Yes (no 3D acceleration)

Windows in BootCamp:
Google Earth: Yes
NASA World Wind: Yes
Microsoft Virtual Earth 3D: Yes
SkylineGlobe: Yes
ESRI ArcGIS Explorer: Yes

So although NASA World Wind and Microsoft Virtual Earth 3D are currently not accessible via Parallels' solution, this will change in a matter of months, either because the Java version of NASA World Wind has come out, or because Parallels adds 3D hardware support to their product.

None of this should mean that developers can stop developing for the Mac, of course. To use Parallels or Boot Camp with Windows, you need to own a copy of XP or Vista, and that's not cheap.

Google Earth KMLs can now be viewed in Google Maps


Why is that important? Because not everyone wants to take the time to download and install Google Earth. Not sure why, but I'm not here to ask these kinds of questions. Do you want Aunt Flo or Gramps to see the great map you made in Google Earth but know they'll have conniptions trying to get Google Earth to work, send them the Google Maps KML.

You need the KML to be web-based (like in the Vassar College BBS site or the Google Earth BBS) and then it can be pasted into the search line in Google Maps.

Here's the cool thing...when you go to the Google Earth BBS, now you have two options, one for for downloading the KML and a new one for downloading the link to view in Google Maps. See the circle below. Hurray!!

Google Earth and Old Maps?!? Be still my heart!



Google Earth in 4D by ZDNet's Garett Rogers -- Google skipped right past the third dimension and landed directly in the fourth (time) by offering historical maps on Google Earth. Now you can travel back in time — for example, I am looking at the globe of 1790. Don't expect detailed high resolution photography from days gone by, but it's still interesting to see [...]

So, in order to make these fantastic archival maps transparent, look at the image below. If you cannot read it, you have to select the folder (highlight it) in the Rumsey collection under the Featured Content and then up in the Places section you'll see the Transparency slider.

Essentials of Environmental Science - GIS Lab
Spatial Analysis of Casperkill Data

In this lab we’ll perform some of the analytical steps you can use to understand the distribution of stream quality parameters, or of risk factors that influence a stream.

The directions in this lab are somewhat terse, in part because I think much of the methods involved are communicated easiest verbally, and in part because it takes a lot of precious time to read directions in the current context. Please do your best to remain flexible, and if you find yourself becoming frustrated with the software, consult with your neighbors and the instructors to sort out a solution. Often we learn a great deal by making mistakes.

We will practice importing points, changing symbols, buffering and clipping, and basic map design as a group. Then you will have time to work on your own. We’ll try to include some show-and-tell to display your work to the group.

Taking notes: it’s hard to pause for note-taking, but it’s a good idea! You will not remember the steps taken today if you don’t take notes. I strongly recommend note taking!


Here is where you’ll find the tools you need:

Symbology: change the colors, sizes, grouping, and so on for point, line, or polygon features by opening the Properties window (double-click or right-click on the layer name), then click on the Symbology tab

Buffer tool: in the Toolbox (click on the red toolbox button to open it), search for the Buffer tool. (normally, use Dissolve Type: ALL)

Clip, Dissolve, and Calculate area are also in the Toolbox (search by name)
Select features by their location in a buffer: under the Selection menu (top of the ArcMap window), find Select by Location.

To examine attributes of selected features: open the attribute table of the layer: right-click on the name of the layer. You can then use Statistics to calculate mean, min, max, and histogram.

Screen capture windows (to paste in a word document): Alt-print screen copies the active window, such as a histogram report. Ctrl-V to paste in a word document.


Possible tasks: (we may not accomplish all of these)
Plot the Casperkill sample sites as points (“events”), using their coordinate locations.
Display the points using point symbols graduated to express data values.

Buffer the stream (at 50, 100, 500, 1000 m).
Clip digitized land use by the buffered area, then calculate area of different classes of land use.

Create a new point shapefile and identify risk factors to the stream, and show those risk factors to the class.


Assignment: Turn in the following next week.
Produce a map (without air photos, but with a legend and scale bar) showing your findings from some (probably not all) of the work above. Write a 1-2 page analysis that explains what you can interpret from what you see in the map. You will be graded on the thoughtfulness of your writing, not on the depth of your GIS work. Your GIS analysis may be very simple, but try to think thoroughly about the evidence you have, the questions it raises, and the information that can be found in it about environmental factors affecting the stream.
As you write, practice writing cleanly and accurately. Stick close to the map and avoid sweeping generalizations, sloppy grammar, and other careless habits. Any figures or tables appended to your written work should have captions, and you should clearly explain what each figure or table shows and what the reader is to learn from it.


digitized data values:
1 = trees
2 = neighborhoods
3 = parking lots
4 = mowed grass
5 = open water
90 = roads
