Santa Clara County parcel data legal battle cited as "ludicrous" by Mercury News
map brain
[info]gcpmaps
I just wanted to give kudos to Scott Herhold for including the Santa Clara County GIS parcel data debacle in his discussion of questionable decisions by city government (see "In My Opinion", page B1) in today's edition of the San Jose Mercury News:



"...Or there was Santa Clara County’s ludicrous decision to keep fighting a public records battle over its geographical mapping system well after it was clear that it was a lost cause. The county wound up paying $600,000 in legal fees, money that could have saved a clutch of jobs."

Proposal for Wikimedia Strategic Planning
map brain
[info]gcpmaps
 I've been sketching out my thoughts on the many ways GeoServer, Wikimedia and GIS in general would benefit from a Wikimedia sponsored implementation of GeoServer.  If you support this concept, please visit this page: 

http://strategy.wikimedia.org/wiki/Proposal:WikiGIS_--_Setup_a_GeoServer_to_Share_Georeferenced_Data

...and look for the What do you think of this proposal? section (at the bottom of the proposal) and rate it accordingly. Many thanks!

Use Case: Student Projects

STUDENTS could post their projects to the Wikimedia GeoServer under a Creative Commons license as a way to publicize their studies and research. Those layers could then be easily found and attributed by other students, organizations or agencies that find their work relevant.

 

[edit]Use Case: Municipal Data

MUNICIPALITIES are heavy users and distributors of GIS information, but GIS Managers often find it very difficult to convince local officials of the benefits of GIS because city governments don't want to finance or deal with the hassle. A Wikimedia GeoServer could become a platform of choice for under-funded municipalities to publish their data layers for public consumption. I suspect that many municipalities who have discovered they have articles on Wikipedia are enjoying some of the benefits. These articles would be tremendously enhanced by the addition of a mechanism for citizens to download municipal map layers. Organizations like the First Amendment Coalition have been working hard to establish county parcel geodata layers to be made available to citizens under the Public Records Act. Being able to find this information through a Wikimedia GeoServer would reduce the number of at cost CD-ROM duplicates local agencies have to make and save citizens a trip, and wait in line, at the planning office.

 

[edit]Use Case: Environmental Work

ENVIRONMENTAL RESEARCH is also a heavy user of GIS information because only with geo-referenced data layers can you ask complex spatial questions. In the United States, a primary source for GIS data is the USGS and there is no need to mirror or duplicate their massive catalog on a Wikipedia GeoServer. However, once an organization has performed geospatial analysis and created new layers with their results, these could then be added to the GeoServer for sharing with the world.

Additionally, were examples of the first two use cases available, I suspect that many environmental organizations would find student data and municipal data to be a tremendous complementary source of information to USGS data. Local watershed councils, for example, rarely have the infrastructure to publish their actual geodata because they are underfunded and hyper-focused on collecting the data. A Wikimedia GeoServer would be a great service to them and a potentially powerful way to increase awareness of Wikimedia at the grass roots.

Trimble Training Experience
map brain
[info]gcpmaps
     I finished a two-day course called "ArcPad 8.0 for Mobile GIS" today.  In the course we were trained to use the nimble Windows Mobile 6.0 driven Trimble Juno SB device (the nimble Trimble?) in conjunction with ESRI ArcPad 8.0.  The course at Ohlone College's stunning Newark, California campus was attended by a cross section of GIS professionals, college instructors, high school and grade school instructors.  The course was very well organized and covered a lot of material at a pace comfortable for all.  While the course would probably benefit by requiring some pre-requisite experience with ArcGIS, I recommend this course to anyone interested in serious geospatial data development.

     The Trimble Juno uses a GPS SiRF chip to communicate with satellites and WAAS stations for either real-time or CORS based differential correction and promises a 68% benchmark of 5 meter or less accuracy.  In the ideal conditions of the south Baylands around the Newark campus of Ohlone College the devices far exceeded this with up to 95% of features caputured by some members of class coming in at <5m.  The device is light, rugged and worked fairly well with ArcPad 8.0.  The color screen is easier to see in direct sunlight than older devices.

     I'll have more on this topic in days to come.

Dear All:

I am very pleased to announce the following public presentation:

Thoreau’s Cartographic Explorations: Imaging Nature through Maps

John W. Hessler, Senior Cartographic Librarian, Geography and Map
Division, Library of Congress

Mattson/New York Times Lecture, Osher Map Library and Smith Center for
Cartographic Education, University of Southern Maine

Hannaford Lecture Hall, Abromson Center, University of Southern Maine
(Portland Campus)

7pm, 16 October 2009

Free; open to the public

Henry David Thoreau is famous as the author of Walden (1854), The Maine Woods (1864), and other classics of American transcendental literature. Less well known is his work as a land surveyor in Concord, Mass., work that allowed him to examine nature at length and in detail.  Still unexamined is his interest in the early European maps of North America. Thoreau gave a brief history of the mapping of New England in his Cape Cod (1865). He also carefully redrew to scale maps by Champlain, Wytfliet, Ortelius, and other early writers on the New World for his unpublished “Canadian” and “Indian” notebooks. Mr. Hessler’s recent identification of two copies of Champlain’s maps as being Thoreau’s handiwork has led him to investigate this hitherto unappreciated aspect of Thoreau’s life and works, and to locate other map copies by Thoreau now missing from the notebooks. These cartographic explorations, especially with respect to the recording of indigenous toponyms, informed Thoreau’s notions of the American wilderness and his environmental imagination. This lecture is the first public presentation of this exciting, new research.

N.B. We hope to feature some of the maps related to Thoreau's work in the Osher Map Library’s exhibition, /American Treasures/, which opens on 15 October.

This public presentation is part of the celebration of the reopening of the Osher Map Library and Smith Center for Cartographic Education at the University of Southern Maine. In addition to the lecture and exhibition, this celebration includes a one-day conference -- New Directions in the Study of Early American Cartographies -- on 17 October and public open house and ribbon-cutting on 18 October.

Keyspan USA-19HS Wants COM1
map brain
[info]gcpmaps
I have taken on a new role as GIS Specialist for the Stevens and Permanente Creek  Watershed Council. As a volunteer-based organization supported by donations of time, energy and equipment we are using older model Trimble GeoExplorer 3 units.  However, I like them very much*.  I snagged one on eBay ($300)  for personal/off duty use as well as to simplify my data management for the next couple of years by not having to juggle technologies. 

* (I spoke with a colleague recently who said he actually likes the GeoExplorer 3 better than the new Tirimble Juno Windows CE units because they do not require a stylus and because they feature a monochrome LCD screen they are easier to use in bright sunlit conditions.)

If you decide to take a similar route and want to use legacy Trimble units with a newer notebook computer that does not have a serial port, you'll need something like the Keyspan-by-Tripp Lite USB High-Speed Serial Adapter.  I give this cable pretty high marks for return on your $45 investment.  It is both well designed and works with Macs and PCs.  When attached, it appears as a standard COM port and the driver includes a port testing tab that instills confidence if you're having trouble communicating with an external serial device.  

For example, the GeoExplorer 3 ships with an older version of Pathfinder Office (v2.80) and I had trouble figuring out why the Keyspan serial adapter port tests indicated all systems were go, but Pathfinder Office could not connect to my Trimble units.  After updating the Keyspan drivers and reinstalling Pathfinder Office, I finally took a closer look at my port settings. 

I occasionally use a Sierra Wireless WiFi card that we pay through the nose to Sprint for monthly anywhere access.  While a very sleek and handy device, it seems to be rather careless in its port assignments having over the last year been assigned variously to COM ports 3 through 19.  This explains why the Keyspan adapter was by default being assigned to COM20. 

Upon recognizing this, it occurred to me that perhaps in the days when Pathfinder Office 2.80 was being programmed that having a COM20 assignment  might not have been taken into account.  While I cannot confirm this is the case, I can report that changing the port assignment to COM1 on the KeySpan adapter does in fact allow my GeoExplorer 3 to successfully communicate with my Toshiba Satellite laptop.

To change the port on a PC, follow these simple steps after connecting and installing the latest driver for  your USB to Serial cable:

     Open CONTROL PANEL.
     Select SYSTEM.
     Selet HARDWARE tab.
     Open DEVICE MANAGER.
     Click on COMPORTS.
     Right click on the Keyspan (COMxx).
     Change the port number.
     Click APPLY.




ASPRS is Celebrating 75 Years

[info]gcpmaps
I received a lovely 75th Anniversary ASPRS pin in the mail today.  It included a brief overview of the organization that I thought I'd share here.  How delightfully appropriate to have a photogrammetric organization founded by someone with the surname of "Birdseye"!

Cheers,
Christine

---------------------------------------------------------------------------

"ASPRS is proudly celebrating its 75th Anniversary throughout 2009, with special events taking place at the 2009 Annual Conference in Baltimore.

This celebration would not be happening if 12 men, led by Col. Claude Birdseye, had not met in July 1934 in Washington, D.C. to discuss forming a photogrammetric society in the United States that came to be called The American Society of Photogrammetry (ASP).

In the early years of 1934-1935, the ASP boasted 354 members.  Due to continuing technological evolution in the field, in the mid 1980s the ASP Board of Directors agreed to a name change for the organization, incorporating the words "Remote Sensing" to become The American Society for Photogrammetry and Remote Sensing (ASPRS).  Today ASPRS boasts more than 6,000 members who continue to carry the same strong dedication to the profession that the founders had 75 years ago.

...We hope that you will register for the upcoming 2009 Annual Conference and be a part of this momentous occasion.  The conference program and registration form are available online at http://www.asprs.org/baltimore09.  Please come and participate as we reflect on the past and set our sights on the future."

GIS at 1:50,000,000
map brain
[info]gcpmaps
     Yesterday I had a chance to give a casual tour of GIS as it relates to XML for some friends at Foothill College who are preparing some class materials for 2009. So I thought I'd share them here as well.

     This offering does not claim to be exhaustive or comprehensive, but I can personally vouch for the legitimacy and overall usefulness of all the resources listed here.

|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

Hi Paula and Bob,

    I enjoyed spending some time with you both as well. One of the drawbacks of being a freelancer is that there seem so few opportunities to talk about work with anyone who cares. Here's a simple recapitulation of our discussion.

Major consumer priced and open source GIS development products

Principle spatial database platforms


Shape Files (http://en.wikipedia.org/wiki/Shapefile)

     Shape files remain the most ubiquitous data format, for now. These are aggregate files that may include up to seven or eight files working together to generate a point, multi-point, line, multi-line, polygon or multi-polygon that may have attribute data (.dbf) and a projection (.prj) in addition to its format (.shp), index (.shx), spatial index (.sbn) and metadata (.xml). Helpful utilities for converting to and from shape files include:

Typical GIS work flow

0. Get a hair-brained scheme for making a map.
1. Collect a bunch of shapefiles from the web.
2. Create a GIS project to combine and project the shapefiles.
3. Save the shapefiles you've got working together into a single geodatabase.
4. Perhaps create an actual map!  (Don't forget your North arrow, legend, scale and title.)
5. Figure out a way to get your project online using either a mashup or KML.


Major intersections of GIS with XML

1. GML (Geographic Markup Language) used primarily by GeoServer (http://www.opengeospatial.org/standards/gml)
2. GeoRSS is used by most mashup APIs. (http://georss.org)
3. KML used to place your data into a true geodesic context via Google Earth or the Google Earth browser plugin. May also be used in conjunction with Google Maps. (http://code.google.com/apis/kml/documentation/)
