5. Networked Data Access at NCSU Geodata Server –Mapped drive from Windows, Mac map to roanoke.lib.ad.ncsu.edu –FTP (ftp://gisdata.lib.ncsu.edu) –HTTP (Web) for off campus access, requires authentication http://www.lib.ncsu.edu/stacks/gis/geodata.html

6. Data Distribution Federally produced unclassified data is public- domain State, local, and commercial data are held by NCSU under distribution agreements that limit their use to NCSU affiliated users for educational purposes only. Distribution of data for “un-seeable” features (underground infrastructure) is being stopped for homeland security.

7. Factors in Choosing Geospatial Data 1.Source - Fed, state, local, international, other 2.Extent - watershed, Census tract, county, state, etc. 3.Age - 1-2 years old vs. 3-7 vs. 8 or more 4.Data accuracy and scale - positional and Attribute 5.File size - How much free space do you have? 6.Attribute availability 7.Metadata availability 8.File/Image Format 9.Projection and Datum 10.Use Restrictions

8. Federal Data Sources Federal data is public-domain and easily downloaded from numerous websites. http://www.geodata.gov - Federal data portal linked to agency data sourceshttp://www.geodata.gov http://nationalatlas.gov - Interactive mapping and downloadhttp://nationalatlas.gov http://nationalmap.usgs.gov - Cascading Map Serverhttp://nationalmap.usgs.gov

9. State Data Sources NC Center for Geographic Info. & Analysis –Wide range of data, over 100 different layers –Scale: mostly 1:24,000 to 1:100,000 –Available to NCSU via geodata server NC DOT –http://www.ncdot.org/planning/statewide/gishttp://www.ncdot.org/planning/statewide/gis –DOT data, contours, FEMA flood, ’93 aerial photos, USGS DRG’s, NCSU PrecisionAg (Soil Science) - http://www.precisionag.ncsu.edu/ http://www.precisionag.ncsu.edu/ - Census, DLG, NRCS soils, ’98 Color IR Orthophotos

10. Local Data Layers and Sources Typical layers include parcels, street centerlines, digital orthophotos, miscellaneous districts, zones, infrastructure, and cultural features. Sources: –Download from the Web –Available from the library –Acquire directly from the city/county. http://www.lib.ncsu.edu/stacks/gis/counties.html

11. Feature Data Acquisition Status

12. Other Data Sources Council of Governments, Ex/ Regional open space Utilities University Faculty and Peers Commercial data products, usually originate from govt. sources, but are value added -Maptech -Delorme -National Geographic -Geolytics

13. Digital Orthophotos

14. Census Data Resources-Web Download TIGER shapefiles from http://www.esri.com/data/download/census2000_ tigerline/index.html - Some basic tables can be downloaded here too Generate tables from - American Factfinder: (http://factfinder.census.gov/) orhttp://factfinder.census.gov/ - NC State Data Center (http://census.state.nc.us/)(http://census.state.nc.us/ - Be sure to get a geographic ID field to join your tables to the shapefiles.

15. Recent Acquisitions Delorme’s Xmap 4.5 –Complete US coverage of DRGs on an external hard drive, plus 3-D viewing available at DH Hill GIS workstation Maptech’s DigitalCharts –NOAA digitized Nautical Charts and photos -Norfolk VA to Florida plus Intracoastal Waterway

16. LIDAR LIght Detection And Ranging. Measure distance, speed, rotation, chemical composition/concentration of a remote object Airborne LIDAR for the flood mapping program has been collected for 2/3 of NC. This data can be processed for many different applications Symposium being planned for May 14

17. NC OneMap

18. NCFloodmaps.com Web Data Viewer Property/Flood Zone Lookup Tool Data Download Tool – flood zones – state govt. data – local govt. data –20 and 50ft. ASCII digital elevation data

19. National Digital Information Infrastructure Program Proposal (NDIIPP) NDIIPP is a Library of Congress effort focused on preservation of digital resources. Our proposal focuses on NC state/local geospatial data partnering with CGIA. Try to acquire data, document it with preservation metadata, and ingest it into digital repository for long term maintenance, investigate new protocols. Content: feature data, imagery, digital maps, tabular 3 year grant--$1 million+ project, 4-6 total awards. Slim chance of us receiving, but we’re still in the running
