Sample datasets

Most of GRASS's tutorials and help page examples are built around two sample datasets. You can download them from the GRASS website (or a local mirror)

• Spearfish, South Dakota - this dataset has been with GRASS for many years.

• North Carolina - this is a newly developed dataset with modern layers. (e.g. shortest path bus routing, SQL database queries)
  • The original shapefiles for Wake county in the North Carolina dataset are available at http://www.wakegov.com/gis/services/data.htm
  • Metadata for these shapefiles are available at ftp://wakeftp.co.wake.nc.us/gis/Webdownloads/METADATA/

If you would like to experiment with some local data, have a look at the Global datasets wiki page.

Ideas for new datasets

Data organization

• provided as separate MAPSETS that can be inserted into nc_spm_08 or gisdemo_ncspm
• each MAPSET will have at least one example of application

Proposed new MAPSETS

• Road and street networks (nconemap, ncdot) from http://www.ncdot.org/it/gis/DataDistribution/DOTData/default.html
• LRS road network, Integrated Statewide Road network, Bike Paths
• updated streets for wake http://www.wakegov.com/gis/services/data.htm
• add boundaries and POI for reference?
• include emergency centers ? hurricane evacuation routes? potential emergency shelters?
• include stream network?

New MAPSET Time_series_coast

• Coastal lidar point clouds, 1m res DEMs, orthos, 15 years in 10-15 snapshots
• An extended version of this is available at http://courses.ncsu.edu/mea582/common/media/01/NagsHead_series.zip, also used for coastal analysis toolbox add-ons

New MAPSET Landuse_img

• new 4 channel 1m res 2009 imagery NAID
• new NLCD 2006 from USGS and NLCD2001
• 0.15m res ortho?
• Include any post storm, post hurricane, post flood imagery for training purposes? See example here: http://www.ncdot.org/it/gis/DataDistribution/SpecialData/NCStormDamageAndCleanup.html

New MAPSET Time_series_census

this may take more time to prepare

data are available for 1970,80,90,2000,2010

combine with election districts?

LOCATIONS

• Clean up and provide nc_ll, nc_utm, nc_spf for testing projections

EXTERNAL data sets for testing external data formats

• point cloud asci, las
• shape
• geodatabase?
• MRsid, geotiff?

Anything else from here?

• Course material http://courses.ncsu.edu/mea582/common/GIS_anal_lecture/GIS_Anal_webdata.html
• Additional data for North Carolina http://www.nconemap.com/Default.aspx?tabid=286
• Additional data for Wake county in North Carolina http://www.wakegov.com/gis/services/data.htm
