Hi, I have a lot of experience on OSM and OpenJUMP. I am mostly using OpenJUMP for visualizing OSM data. An example of OJ rendered OSM map can be found here: http://wiki.openstreetmap.org/index.php/WikiProject_Finland
My workflow includes: - Importing OSM data to PostGIS with osm2pgsql utility - Reprojecting data to Finnish coordinate system with PostGIS and a little bit classification Editing OSM data is of course possible but exporting edits to OSM database is not a big pleasure. I have tried that it is possible to do at least by: - Saving edits to shapefile - Converting shapefile to gpx format (attributes are lost) - Reading gpx file into JOSM editor - Converting gpx to OSM format with JOSM - Writing in attributes with JOSM and uploading data OSM data might be painful to import to OpenJUMP directly, because it does not have a traditional schema. Instead each feature can have however many attributes (tags). Relations for attributes are missing, though, and therefore a feature can only have one attribute of a kind. Poin can present either amenity=bar or amenity=restaurant, but not both of them. In osm2pgsql the problem of missing schema is solved simply be making a list of attributes to be imported and creating schema for table according to this list. It means that other tags are not imported at all. Another problem with OJ could be that OSM has topology, vertices (nodes) can be shared by several higher lever features. I do not know how well OJ handles this. QGis has OSM plugin but I have never tried it and don't know how it is handling the data. -Jukka Rahkonen- Stefan Steiniger wrote: Hei, I am just curious. In particular because: - Steve Singer adapted the roadmatcher source code to work with OpenJUMP, so the OSM people can integrate Canadian Data from the official topographic service with existing OSM data - I meet somebody from OSM this weekend, which planned to do the above with OJ. - This person (Richard Weait) asked me if I would present at the OSM conference in Amsterdam - because OJ is perfect for data editing and this may give as new users and even developers (Richard told me that the contributor list is doubling every 6 month, now being about 100'000 - and they also attract people who are interested in developing tools). - The OSM wiki even mentions OpenJUMP as tool: http://wiki.openstreetmap.org/index.php/OpenJUMP I created a list of possible things that need to be addressed when working with OSM data after meeting Richard containing: GML template, Projection stuff, GPS import tools, particular tools to create lines from points and tools for data cleaning (I guess the later may be out there - since they have these online tools), among a couple of other things. We actually should have made this another GSofC proposal. On the other hand - Richard told me, that there may be a chance to get some small funding from one of the OSM service companies for a student that is willing to work on such things (but of course - nothing is for sure). so...anyone? or any thoughts? stefan ------------------------------------------------------------------------------ Stay on top of everything new and different, both inside and around Java (TM) technology - register by April 22, and save $200 on the JavaOne (SM) conference, June 2-5, 2009, San Francisco. 300 plus technical and hands-on sessions.
