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.

                           Mailing Lists

        There are two primary mailman lists set up for DLSLUG, an
        Announce list and a Discuss list. Please sign up for the
        Announce list (moderated, low-volume) to stay apprised of
        the group's activities and the Discuss list (unmoderated)
        for group discussion. Links to the mailing lists are on the

                         Tell Your Friends

        Please pass this announcement along to anyone else who may
        be interested.
