My home state is Alaska where very little OSM mapping has been done. I have been wanting to add national parks, wilderness areas and national wildlife refuges to the Alaska map but with the exception of a few wilderness areas, have not done so because I don't have any experience with such large projects.<div>
<br></div><div>I obtained from the National Park Service, Denali National Park office, shape files for all the Alaska National Parks. I see no reference to any Alaska imports of national parks on this list so I'm asking for input, suggestions, etc., on how to go about this. Naturally, I think you'll agree that having these areas in the OSM database is a very worthwhile project.</div>
<div><br></div><div>The file I have is 9 MB in size and includes boundary information for ALL national parks in Alaska. I was able to load the entire dataset into JOSM using the OpenData plugin. It took quite a while, roughly 30 minutes on a pretty fast laptop with 8 GB of RAM, and the data looks good. But it's complex. No, I'm not going to upload any of that data at this point. My plan is to discuss it here and then if all goes well, split that large file up using Qgis and then deal with one park at a time.</div>
<div><br></div><div>The data was obtained from the Denali National Park Resident GIS specialist, who is also an OSM mapper, although he's very new to the OSM world. He is user:NJSkunk</div><div><br></div><div>That's my initial question then. How to go about this in a responsible manner? </div>
</div></blockquote></div><br>Dave,</div><div class="gmail_extra">From a quick survey of US National Parks, I agree that Alaska's National Parks are neglected. At the time I did the survey, some only had a single node representing the park. It is great that you are willing to improve the parks.</div>
<div class="gmail_extra"><br></div><div class="gmail_extra">To get started, take a look at the Great Smoky Mountain NP import wiki page: <a href="https://wiki.openstreetmap.org/wiki/Great_Smoky_Mountains_National_Park">https://wiki.openstreetmap.org/wiki/Great_Smoky_Mountains_National_Park</a> </div>
<div class="gmail_extra"><br></div><div class="gmail_extra">You will need to create a similar page for your Alaska Plans. I'd suggest starting with one park to get started. You can also look at the Seattle Import page for a more compact format. <a href="https://wiki.openstreetmap.org/wiki/Seattle_Import">https://wiki.openstreetmap.org/wiki/Seattle_Import</a>. </div>
<div class="gmail_extra"><br></div><div class="gmail_extra">I would also highly recommend joining in the US Import Conference Call. Join the US Import mailing list for announcements. They occur every other Monday at 1PM EDT. We use google hangout for the call. You can discuss your plans with the group. </div>
<div class="gmail_extra"><br></div><div class="gmail_extra">For handling the data you have some options. Python is a great tool, unfortunately, I'm not familiar with python, I'll tell you about using PostGIS, QGIS and ogr2osm.py. I find using PostGIS along with QGIS a great way to clean up the data. Once you've simplified the data, export the data as a shapefile and run through ogr2osm.py to convert to a .osm file that can be loaded as a layer in JOSM. I use JOSM to simplify ways. It can also be done using PostGIS or QGIS. The resulting .osm file should be made available to the community for validation before importing. </div>
<div class="gmail_extra"><br></div><div class="gmail_extra">The NPS is fully behind moving their data into OSM. If you need more parks help, we can call on them for assistance. </div><div class="gmail_extra"><br></div><div class="gmail_extra">
