Agenda
11:00 OpenStreetMap Mapping Party!
lead by Russ Nelson
Attendees will learn how to create OpenStreetMap data.
Bring a GPS receiver of any supported type and learn how to
acquire and upload GPS data, create and edit OpenStreetMap
data using portable applications, add labels and details to
data, and render and use maps.
The day will start with an introduction (be sure to attend the
Thursday night meeting for the full details) and instruction and
then head out to gather some data. The group will reconvene at
the classroom, and learn how to upload and process the data to
make maps.
Reviews of all kinds of GPS-specific or GPS-enabled devices
that can be used for OpenStreetMap can be found here:

with some manufacturer-specific reviews for more popular units

As general advice, it's useful to have a device with expansion
memory. For example, in the Garmin series, there is an HC and an
HCx model line, with the -x models able to take an SD card to
store *much* more data.
OpenStreetMap is geodata, a collection of locations
(intersections), connections between them (roads), and
connections between the connections (bus routes). All of these
can have arbitrary amounts of metadata stored with them, like
names, speed limits, purpose of the road, etc. All of this is
stored in a PostgreSQL database and available through an API
which presents a simpler interface than raw SQL queries.
With all of this data in hand, you can make a map. But maps
aren't new; why is OpenStreetMap (OSM) new? OpenStreetMap is
licensed under a community reciprocal license, so that people
who contribute to it are confident that the people who
distribute it will reciprocate under the same license. Unlike
public domain data like the Census's TIGER data, OSM has a
custodian who wants your contributions. Unlike proprietary data
like Google Maps, or its underlying proprietary geodata, OSM
is freely copyable and open to all for editing.
Russ Nelson is an early Linux adopter; in fact an early adopter
of all sorts of technology, including the first non-Compaq iPAQ
reflashed to run Linux. He finally gave up on assembly language
a few years ago and now programs in C and most languages
beginning with P. He almost got a PhD from Clarkson University
but managed to escape writing a dissertation.
Russ has been giving away his software since he started
writing it in 1974. Prior to his GPLed Freemacs package,
there weren't many people to distribute it to. He really came to
the fore with his Packet Driver Collection, begun while a
staff member at Clarkson. A GPL'ed set of DOS Ethernet
drivers, they arguably put GPL'ed software on more CPU's than
anything prior to Linux. Supporting free software full-time
since 1991, Russell is a founding member of the Open Source
Initiative and a Cloudmate Community Ambassador. He lives in
Potsdam, NY with his wife and two nearly-adult children, but
was born in NYC and raised in Baldwin out in Nassau County.
