California GIS Maps and Data Sets

  • NKCA 2.0 (Neighborhood Knowledge California) @ UCLA Advanced Policy Institute - newly updated with added data sets, extraordinary site offers numerous options for creating maps or data reports for California counties and cites. A singularly great place to learn about the basic power and magic of GIS mapping.

  • California Department of Education (CDE) - provides two ways to look up demographic information for counties, districts, and schools:
    • Ed-Data Partnership - offers financial, demographic, and performance data for California K-12 public schools at the state, county, school district, or individual school level. (You can search for data as far back as the 1992-93 school year.) The site will display some of the information in a pie-chart format.
    • DataQuest - much of the same data as Ed-Data, above, but it can be manipulated (in the good sense) to provide very specific data in a spreadsheet format. It also will compare the school or district data with the state and county data.
  • California Metropolitan Transportation Commission (MTC) - Maps and GIS Data
  • California Spatial Information Library (CaSIL) - pretty much the California GIS mother lode; the range of data here is extremely broad, while specialized and useful for advocates, including core political data:
    • Frequently Accessed Data
  • California Statewide Database (SWDB) @ Berkeley - the redistricting database for the state of California; compiled from census data, free to those interested in the political and demographic characteristics of California.
  • Sacramento County - Special Reports on Community Issues @ Community Services Planning Council - includes:
    • Sacramento County Snap Shot (May 2005) - scores of GIS maps and charts compiled for Sacramento County at the sub-county (ZIP Code) level; includes information on language, education level, income and poverty, public assistance, and health & safety.
    • A Regional View of Social Disparities (May 2004) - collection of 44 maps visualizing the socio-economic status of the Greater Sacramento (eight county) Region); uses GIS mapping to illustrate the spatial distribution of the demographic, social, economic and educational characteristics of the people living in the region.
  • Websites for Digital GIS Data @ Stanford
    • Resources for Finding GIS Data

It offers a good, practical layperson's introduction to and overview of GIS mapping, a useful, focused list of basic online GIS resources, along with real world examples of how GIS mapping has been and can be used to better understand and analyze data in support of economic and community development. Well worth the click-thru.

  • Map Layers Warehouse @ NationalAtlas.gov - free map layers include national data and map layers for mapping of select census populations.
  • Scorecard.org - among other online mapping features and statistical tools available here, you can enter a zip code and get a list of pollutants emitted in that area and who emits them; search by geographic area or company name; and find rankings for lead hazards, land contamination (Superfund) according to state, county or census tract. And there's more! You can rank on country or state level and lists companies responsible; show degrees of environmental burdens felt by different racial and income groups in each county in English or Spanish; and allows you to rank the top issues in the designated area based on comparative risk projects.
  • Social Explorer - another national GIS mapping tool with more limited data sets, but interesting demos of how to effectively map data.
