I'm an old Fortran programmer who's learned to hack together Java, PERL. etc. but I've never tried reading/writing shapefiles or XML. Should be fun to learn. Initial import: STRCLASS is the street class as defined by Clark County GIS (CCGIS). 1 for each STRCLASS in county shapefile 2 create scl.osm preserving attributes as ccgis: tags 3 extract working.osm from planet.osm with the same bounding box as scl.osm 4 remove ways from scl.osm that are already in working.osm (by comparing ccgis: tags) 5 use JOSM to replace TIGER ways with ways from scl.osm 6 upload changes 7 relax until planet.osm is updated 8 next STRCLASS Step 1 may not be as simple as iterating through STRCLASS. The CCGIS data doesn't clearly identify motorways. I plan to do these in the first iteration by selecting on STRNAME. (That's what inspired step 4.) Steps 2, 3, and 4 should be automated with a script. Updates: 1 create scl.osm preserving attributes as ccgis: tags 2 extract working.osm from planet.osm with the same bounding box as scl.osm 3 create add.osm, delete.osm, and change.osm by comparing ccgis: tags in scl.osm and working.osm 4 review changes.osm with JOSM and upload 5 review add.osm with JOSM and upload 6 process delete.osm (but how?) -- - Joseph Scanlan http://www.qsl.net/n7xsd +1-702-455-3679 http://n7xsd.dyndns.org [EMAIL PROTECTED] (work) (not work) [EMAIL PROTECTED] - So he went inside there to take on what he found.

Osmosis can create the diffs for you, if you keep a local copy of scl.osm (after you upload), then do a diff with a new, updated copy of scl.osm. That should help reduce your update burden.

Re: [Talk-us] Clark County, Nevada Street Center Line data
Joseph, before you embark on this endeavor, make sure that the data is better than the data that was already imported from TIGER. More than likely, it is. I can help you with the convert shapefile to .osm step, as I am slowly working on the SHP - OSM script mentioned previously on this list.

A little quality time with Google and the FAQ led me to this: - Download SCL shapefiles from gisgate.co.clark.nv.us. - Convert the data from State Plane Feet to Lon/Lat (WGS-84). - Convert the shapefiles to .osm format. - Use JOSM to compare and upload the county data. That last step is going to take some time. I guess I'd better get started. -- - Joseph Scanlan http://www.qsl.net/n7xsd +1-702-455-3679 http://n7xsd.dyndns.org [EMAIL PROTECTED] (work) (not work) [EMAIL PROTECTED] - So he went inside there to take on what he found.
