<p>Wiki-Virtualmemorys: /* Participants */</p> <hr /> <div>This is a [[Working Group]] started by the [[Public Geospatial Data Committee]]. <br /> <br /> While OSGeo can consider hosting sets of public geodata, (and for the purposes of offering maintained [[Geodata Packaging Working Group|packages]] of high-quality data for education and demonstration, it probably will), we can compile a set of best practises and references to good prior art for building and maintaining collections of data and metadata. <br /> <br /> == Focus ==<br /> <br /> * Metadata for collections of geographic information.<br /> * Providing best practise and prototypes for geodata search facilities<br /> * Help with providing input into the OSGeo repository/services at http://osgeo.telascience.org/<br /> * Providing 'catalog'/discovery/search services as part of OSGeo activities in promoting access to public domain and open licensed bodies of data.<br /> <br /> == Participants ==<br /> <br /> * [[User:JoWalsh|Jo Walsh]]<br /> * [[User:SchuylerErle|Schuyler Erle]]<br /> * [[User:bitner|David Bitner]]<br /> * [[User:Pnaciona|Perry Nacionales]]<br /> * [[User:Neteler|Markus Neteler]]<br /> * [[User:Arnulf Christl|Arnulf Christl]] <br /> * [[User:virtualmemorys|Bob Wang]]<br /> * ''please add yourself''<br /> <br /> == Existing meta projects and related efforts ==<br /> <br /> * [http://www.mapdex.org/search/ Mapdex] is &quot;a global Index of 2,018 servers, serving 37,168 map services, containing over 400,000 GIS Layers, covering more than 4,000,000 columns!&quot;<br /> * [http://www.geotorrent.org/ GeoTorrent] hosts BitTorrents of shapefile/TIFF format data.<br /> * [http://www.fao.org/geonetwork/ GeoNetwork] &quot;Find Interactive Maps, GIS datasets, Satellite Imagery and Related Applications&quot;<br /> * [http://www.dlese.org/libdev/dcs_overview.html DLESE Collection System] offers a metadata repository and editor<br /> * Web Services lists:<br /> ** http://www.skylab-mobilesystems.com/ger/wms_serverlist.html simple WMS service URL list<br /> ** http://www.refractions.net/white_papers/ogcsurvey/ Automated OGC Survey on the Web (WMF, WFS, ...)<br /> ** http://geometa.info/search.jsp?query=type%3Awms WMS search engine<br /> * US data servers<br /> ** http://datagateway.nrcs.usda.gov/<br /> <br /> == Public Datasets for Possible Mirroring or Distribution ==<br /> <br /> === Gazetteer Data ===<br /> ... basically placenames with coordinates ...<br /> <br /> * [http://earth-info.nga.mil/gns/html/ NGA GNS Gazetteer]<br /> * [http://prdownloads.sourceforge.net/nasa-exp/BlueMarble-Placenames.zip?download WorldWind Placenames] (markusN can provide PERL to read this)<br /> * [http://www.geonames.org/ Geonames.org] gazetteer<br /> <br /> === Vector data ===<br /> * VMAP0 - 1:1Mio, very generalised vector data for many features, around 70 layers<br /> * [http://www.soest.hawaii.edu/wessel/gshhs/gshhs.html GSHHS] - world coastlines, different scales available<br /> * TIGER/Line (USA) - street and addressing data for the US<br /> * RNF (Canada) - street and addressing data for Canada<br /> * [http://www.openstreetmap.org OpenStreetMap] - data available through a [http://wiki.openstreetmap.org/index.php/REST HTTP based XML interface].
