Administrators EmperoR Posted October 10, 2013 Administrators Report Share Posted October 10, 2013 Nice articles related to recent US problem, some nice free data sites is down due to the tight budget, only web that have a critical roles like it said "“the information this site provides is necessary to protect life and property, it will be updated and maintained during the Federal Government shutdown.” so some critical sites still active such as: Disease Maps, coastal erosion hazards information, earthquake information, emergency operations portal, geomagnetic activity,landslide information, volcano information, and water. Likewise, FEMA’s GIS section is still operational. complete articles : Esri has posted about the availability of US Government GIS data on its ArcGIS Online service. Some of the list datasets include US Census population and TIGER files, multi-spectral imagery, USDA agricultural data, soils, land cover, and labor data. The Wayback Machine which archives snapshots of web sites offers access to shuttered US Government sites although I haven’t been able to test if access to data downloads is possible (I would think probably not). Code for America has a list of select US Census TIGER files hosted by OpenStreetMap US Foundation via the Oregon State Open Source Lab. The data includes nationwide boundary files (state and county boundaries) as well as 2013 detailed state files for the blockgroup, places, blocks and tracts levels. Other GIS data warehouses can provide archives of historical US data such as the National Historical Geographic Information Systems (NHGIS) which provides “free of charge, aggregate census data and GIS-compatible boundary files for the United States between 1790 and 2012.” Natural Earth provides free prepackaged global GIS data sets at a variety of scales. The data is available in vector and raster formats at scales of 1:10m, 1:50m, and 1:110 million. The site offers public domain data for a variety of areas including cultural, administrative, and physical GIS data. Also check with local government and statewide agencies for localized data sources. Many state agencies offer federal data cropped to the state level. GPS Post Processing ServicesEven those that GPS to collect their own geospatial data are being impacted by the shutdown. The National Geodetic Survey’s Online Positioning User Service (OPUS) which provided a free online GPS post-processing service is shut down. GPS World lists seven alternative GPS post-processing services in lieu of using OPUS. In addition, NOAA is providing limited CORS GPS data for areas impacted by Tropical Storm Karen. source : http://www.gislounge.com/alternatives-gis-data-u-s-government-shutdown/ Quote Link to comment Share on other sites More sharing options...
