<div class=Section1>
<p class=MsoNormal>Hello all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve developed a python script for exporting from
ArcGIS directly to the .OSM file format used by JOSM. The script is available
here: <a href="http://users.rowan.edu/~reiser/osm/">http://users.rowan.edu/~reiser/osm/</a><o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The script also does the following:<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='font-family:Symbol'><span style='mso-list:Ignore'>·<span
style='font:7.0pt "Times New Roman"'>
</span></span></span><![endif]>Preserves topology. Polygons or lines that share
vertices will become ways that share nodes. Efforts have been made to reduce
the amount of duplicate nodes exported.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='font-family:Symbol'><span style='mso-list:Ignore'>·<span
style='font:7.0pt "Times New Roman"'>
</span></span></span><![endif]>Creates multipolygon relations for multipart
polygons (both internal ring and external part polygons). <o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='font-family:Symbol'><span style='mso-list:Ignore'>·<span
style='font:7.0pt "Times New Roman"'>
</span></span></span><![endif]>Reprojects to WGS84 automatically. <o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span
style='font-family:Symbol'><span style='mso-list:Ignore'>·<span
style='font:7.0pt "Times New Roman"'>
</span></span></span><![endif]>Exports attribute data as keys. Only fields
prefixed with “_” or “osm_” are exported. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The script can be added to ArcToolbox, allowing ArcGIS users
a quick way to export data to OSM. I’m hoping this will encourage small
towns or institutions (like Rowan, also exported to OSM, here: <a
href="http://osm.org/go/ZciXY0SlF-">http://osm.org/go/ZciXY0SlF-</a>) to
contribute to OSM. I used this script to export the land use/land cover data
for the State of New Jersey, which has since been uploaded to OpenStreetMap (<a
href="http://osm.org/go/Zcmube--">http://osm.org/go/Zcmube--</a>). I hope this
will encourage contributions from smaller-scale stakeholders, like myself. (I intend
to keep Rowan up-to-date on OSM, as we may use the platform for on-campus mapping
projects in the future.)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The code has been released under a CC by-sa-nc license. I’d
appreciate any changes or bug fixes to the code, as well as any comments, questions
or complaints. <o:p></o:p></p>
