[Imports] Import US County data
I have obtained a set of road centerlines from a US county that has been published in the public domain. I would like to use this to correct the OSM roads for that county, since the TIGER data was one of the poor alignments that we are so familiar with. In addition, the road names have all been changed for E911 consistency. This file is likely even newer than the 2010 TIGER centerlines. I have used Ian's shp-to-osm to begin looking at the data. 1. Does anyone have a rules file for a typical municipal road centerlines shape file conversion? I started to develop this, but can't believe no one has done this before. 2. Is it good to preserve TIGER tags for untouched roadways, or just delete and replace them? The geometry is so far off that it is easier to delete and replace. Usual import disclaimers - Any relations will be preserved. Any existing road alignment edits will be preserved (such as for interstates) Any existing attribution will be preserved (speed limits, traffic lights, etc) Corrected data will be manually stitched to existing data at borders or pre-edited roads. ___ Imports mailing list Imports@openstreetmap.org http://lists.openstreetmap.org/listinfo/imports
Re: [Imports] Import US County data
With TIGER 2010 starting to roll out we need to think about how to offer some way of comparing OSM with arbitrary datasets. Here are my thoughts so far: 1) User uploads a shapefile 2) User selects attribute(s) in the shapefile to use for matching with OSM data (i.e. a road name or tiger identifier or something) 3) System performs a geospatial match (including the attribute(s) the user specified in step 2) on OSM data in the area of the shapefile 4) System renders a map with three layers: a) data in reference but not found in OSM, b) data in OSM but not found in reference, c) data in both Based on (4), mappers can modify the OSM data to more-closely match the geometry or meta-data of the reference data set. A more complicated version of this tool could allow the mapper to accept wholesale changes in geometry or attributes into the OSM dataset (removing or manipulating the existing data). This is all pretty tricky, but I'd love to hear other people's opinions.

[Imports] Open Threatened Species Map
You can help! Maps wanted for Wikipedia, Commons but data available for OSM. see : http://commons.wikimedia.org/wiki/Commons:IUCN_red_list The IUCN Red List of Threatened Species (also known as the IUCN Red List or Red Data List), founded in 1948, is the world's most comprehensive inventory of the global conservation status of plant and animal species. The International Union for the Conservation of Nature and Natural Resources (IUCN) is the world's main authority on the conservation status of species. Starting in June of 2010, the IUCN red list has authorized the production of distribution maps from their spatial data. There are currently ~25,000 species on the Red List with spatial data. http://www.iucnredlist.org/technical-documents/spatial-data The data is available both in ESRI File Geodatabase format and the ESRI Shapefile format and is held in geographical coordinates. Please note that the files are large, and download times could be quite lengthy. While this data is made freely available to the public, please note that unfortunately we cannot provide technical support for use of the data in analyses or general GIS support. -- James Michael DuPont Member of Free Libre Open Source Software Kosova and Albania flossk.org flossal.org ___ Imports mailing list Imports@openstreetmap.org http://lists.openstreetmap.org/listinfo/imports
