Historic maps of the U.S. Gulf Coast
Feb 7th, 2006 by JTJ

This helpful posting comes from Maps-L at http://www.listserv.uga.edu/archives/maps-l.html

“Folks:

“Wonderful news. About 300 historic map images of the Gulf Coast area are
now available through the Geospatial-One-Stop (GOS) portal. The maps are
USGS topographic quads that were scanned, processed and georeferenced by
USGS scientists. They are in UTM NAD 27 and are uncompressed GeoTIFFs.


“Here's what you need to do to access these images:

“Go to http://www.geodata.gov
Search
Under “what”, type in “Gulf Coast Historic Maps”
You will see the site listed. Select the site, and you'll be placed on an
FTP site.
This site is: ftp://mcmcftp.er.usgs.gov/Katrina/508dpi/

“Log in “anonymously”.

“You will see a long listing of topo map names.

“Remember that you can always find out where these maps are located by
picking up a USGS quad index from 1 888 ASK USGS or online on:
http://catalog.maplink.com/usgs/USMap.html and selecting the state you are
interested in.

“What can you do with these images? You could, for starters, compare the
historic maps to new topos and aerials online, for example, on
terraserver-usa.com, and observe the amount of landscape change from human
activity and from storm surges. Has the coastline changed? If so, how
much, and why?

Are you ready for "GES"? Yup, you've been using it.
Feb 6th, 2006 by JTJ

Susan Smith, exec. editor of GISWeekly Review, delivers a fine overview this week of GES, “Geographic Exploration Systems.”  Check it out.

Zeroing in on Geographic Exploration Systems


by Susan Smith


Nearly every participant in our Emerging Technologies review mentioned
Google Earth technology and how that might impact the future directions
of GIS. Google Earth is exciting and better known to the masses right
now, however, it is not the only “Geographic Exploration System (GES).”

Although it may seem that these GES are a new invention, they
have actually been in the works for quite some time. Technology from
lesser known companies has been used to extend or enhance software for
some of the heavy hitters. Some companies have OEM'd their technology,
others have been the result of outright acquisitions.

ESRI ArcGIS Explorer

ESRI has just released a beta version of its “geospatial information viewer,” ArcGIS Explorer,
which offers an easy way to access geographic information but also
integrates rich GIS datasets and server-based geoprocessing
applications by accessing the ArcGIS Server including geoprocessing and
3D services. It is OGC-compliant, and supports WMS and Google KML data.


Some of its features include:

  • ability to seamlessly explore data for the entire globe in 2D and 3D
  • integrate your local data with data and services from ArcGIS Server, ArcIMS, OGC WMS and ESRI-hosted ArcWeb Services.
  • perform GIS analysis using tasks (i.e. visibility, modeling, proximity, search)
  • answer queries about the maps you generate and share the results with others
  • use maps and data from your own secure servers. [more]


Turn left when you get to Torino (or Turin)

The Google Earth blog reports:

Maps of Torino, Italy – Winter Olympics Site – in Google Earth

By FrankTaylor on Sightseeing

Torino, Italy Olympics in Google EarthGoogleMapsMania recently discovered
that Google quietly added a more detailed road map for the Torino,
Italy area for Google Local. What is interesting is that in Google
Earth we have already had these more detailed road maps. But, not just
for that small area. Google Earth's more detailed road maps cover most
of Europe now.

To see the roads, you just turn on the “Roads” layer, wait for them
to load, and start zooming in. Another big difference in GE is that the
road maps adjust their level of detail according to your zoom level,
and you can adjust your view dynamically including your tilt and see the 3D terrain. You can go to Torino, Italy
now and see the mountains where the Olympics will be held. Also, in
Google Earth you can see the detail of the satellite and aerial photos
so much better than in Google Maps.




Measuring and visualizing words
Feb 3rd, 2006 by JTJ

In recent weeks a sub-set of journalists have begun working with the problem of how do we  quantify and illustrate speech.  Or speeches.  The Cyberjournalist.net newsletter (at the American Press Institute) reports:

latimes.com's Eric Ulken built keyword clouds
comparing the text of President Bush's first State of the Union address
— delivered less than five months after the terrorist attacks of Sept.
11, 2001 — with Tuesday's 50-minute speech.

They list commonly-occurring words in the speeches, giving greater
visual weight to those that appear more often. Arranged side-by-side,
they show some interesting contrasts (and similarities).”

Sorta interesting, when it's working.  We applaude the attempt as a fine beginning, but what's missing is some context and explanation, the “So what?” factor.  In fairness, the site's author recognizes the shortcoming, saying: “Of course, they lack any kind of context, but who needs that? (We're kidding.)

On the other coast, ever-inventive Matt Ericson takes another bite of the State of the Union apple and offers up a more interesting visual, “The Words That Were Used.”  [Look in the left column for link to graphic.  But the toned “bubbles” actually show up better in print than online, so if you can't see it well online, try this (and may the copyright gods forgive us).

    We are seeing customized versions of Google Maps
    being used in all kinds of creative ways across the Web. When you get a
    chance, check out the dozens of interesting implementations at Lifehack's Essential Resources for Google Maps.

    These customized maps are easy to use, but not really easy to create. Even with such guides as “How to add a Google Map to any webpage in less than 10 minutes” and tools like MapBuilder.net, creating your own customized map is something best left to ultra-techies (I am not one; I haven't tried it myself).

    But there is another, easier option for creating your own maps using
    what I have been calling a collective media project. For several
    columns now, I have been asking you to to help us with the Web Tips Frappr Project — a way to show you how the free site Frappr.com uses Google Maps to create maps just for you.

    More than 180 responses came in, identifying Web Tips readers around
    the world — the cyber equivalent of sticking color-coded pins on a
    wall map.

    Web Tips Frappr Project
    Readers of this column can join the Web Tips Frappr Project.

    I have been using
    Frappr to create several different Google Maps. Among them: one to
    track every city that my two-year-old twins have visited; another to
    track the towns in India that I am taking 16 of my Columbia students on
    a reporting trip; a map to link members of my extended family around
    the world; and another for the cities that my father served in as an
    Indian diplomat. While these are, in theory, publicly visible, because
    they aren't really linked to anything, they benefit from “security by
    obscurity.” If a Google Map is created in the virtual forest, does
    anyone know?

    You can see some of your fellow readers by going to the Web Tips Frappr Project right now. If you'd like to join them, when you get there, click on “add yourself” on the right of your screen.

    If you live in the U.S., put in your name and zip code. Attach a
    photo (if you wish — optional!). Remove the “Create a Frappr Account
    for me” (if you don't want one) by clicking on checkbox. Hit “Add Me.”

    If you live outside the U.S., put in your name, then click on “Not
    in the U.S.? Click Here.” Start typing your city, and a menu with your
    city should show up. Attach a photo (optional). Remove the “Create a
    Frappr Account for me” (if you don't want one) by clicking on checkbox.
    Hit “Add Me.”

    I look forward to your Google Maps and Frappr feedback at this link or via e-mail to poynter@sree.net.

    Speaking of maps, see Jon Dube's column about using a site called Placeopedia.

    In a future column, Jon or I will discuss how to use the downloadable Google Earth software (now available for Macs, too) for more than just looking at your childhood home or the Grand Canyon.

    Meanwhile, I am still working on my follow-up column about Social Networking for Journalists, and looking to connect with readers at LinkedIn.com.
