As a raster analyst, there are a lot times I try to "fix" many types of raster data from various online sources. If you're going to get data from elsewhere, there are many reliable sources available for GIS data, some websites that charge a fee, and some that are really well-done free clearing houses and data centers.



A few of my favorite national and state/regional sources for GIS raster data are:

Geo.Data.gov - http://geo.data.gov/geoportal/catalog/main/home.page

USDA Geospatial Data Gateway- http://datagateway.nrcs.usda.gov/

USGS Seamless - http://seamless.usgs.gov/

GeoCommunity - http://data.geocomm.com/

EPA - http://www.epa.gov/geospatial/data.html

Great Lakes Coastal Planning - http://aqua.wisc.edu/cpr/Default.aspx?tabid=85

TNRIS - http://www.tnris.state.tx.us/DataCatalog/Index.aspx

North Carolina One Map - http://www.nconemap.com/

Minnesota - http://deli.dnr.state.mn.us/data_search.html

California - http://atlas.ca.gov/download.html

ArcGIS Online - http://www.arcgis.com/home/

National Hydrography Dataset - http://www.horizon-systems.com/nhdplus/data.php
