Thank you Chris for the information. <br>I have the following queries.<br><br><div class="gmail_quote">On Sat, Sep 19, 2009 at 12:58 PM, Chris Hunter <span dir="ltr"><<a href="mailto:chunter952@gmail.com">chunter952@gmail.com</a>></span> wrote:<br>

<li>If the imagery is high enough resolution, identify and tag as many landmarks as practical (buildings, parking lots, etc...)</li><li>Divide the campus out into to whatever size chunks make sense to you and make sure there's at least 1 GPSr available per chunk.</li>
<li>If possible, start assigning chunks to people as they sign up for the event. Try for groups of 2-4 mappers.</li><li>Make sure you have access to a flatbed scanner.<br></li></ol></blockquote><div>> Do we need to scan the maps printed with the points marked? I thought GPS points could be enough to use with JOSM..? <br>

</li><li>Install JOSM, GPSBabel, Yahoo Imagery fix for JOSM, etc... on each workstation that will be used after the walking portion of the event.</li><li>Install whatever JOSM plugins you feel are appropriate. (walking papers, buildings tool, WMS, usertools, etc...)<br>
</li></ol></blockquote><div>> Im not sure about the plugins for JOSM and new to them. How do I identify those required for this purpose? <br></div><div> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Start of the event:<br><ol><li>Pass out pens, walking papers and GPSrs to each mapping group.</li><li>Make sure each group knows how to use the Average function in the GPSr.</li><li>Have each group use the walking papers to sketch / write down their observations. Whenever practical, shoot a waypoint next to anything interesting and mark the waypoint number on the walking papers (saves time trying to name the waypoint in the GPSr memory). Alternatively, use netbooks with the LiveGPS and Surveyor plugins)</li>
</ol>After finishing the groundwork portion of the event:<br><ol><li>Have one person collect and start scanning all of the walking papers.<br></li></ol></blockquote><div>> What is the necessity for scanning the walking papers? </div>

</li><ol><li>File 1 should be only the waypoints without any tracks. - Each mapper in each group will need a copy of this file.<br></li><li>File 2 should be the tracks without any waypoints. - Upload this file to the OSM servers as a public trace.<br>

<ol><ol><li></li></ol><li>Pass the paperwork back to each group. Open the waypoints GPX in JOSM, and download the OSM data for the area.</li>
<li>Use the walking-papers plugin to download the scanned paperwork as a rectified image in JOSM. (Note: there's a bug in the walking-papers plugin that will freeze JOSM if you download the walking-papers imagery before the OSM data.)</li>
<li>Start Mapping.</li></ol></blockquote><div>> I just need to mark the waypoints GPX into the data downloaded from OSM? <br></div><div> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
