STEM II Data Sources

Feb - 07 - 2007

*******************************************************************************************************************************************************************************************************************************************************

     There where three major data sources of GIS data for STEM II : U.S. Census Bureau, Diva-GIS and the United Nations Global Resource Information Database (GRID) - Europe. The difference among these data
sources is that the Diva-GIS data set DOES NOT contain area or population data, whereas the data set for Europe from the UN-GRID already comes with both area and population data. Similarly, area and population
data for the USA, Puerto Rico, Alaska and other U.S. Territories are provided by the U.S. Census Burea in separate files. Another difference
is that the Diva-GIS provides data at administration levels 0, 1, and 2. On the other hand, all data from UN-GRID is only level 1. To be able to use the Diva-GIS data, we had to complement it by search both the
area and population data for locations using a variety of online sources : CIA Factbook, City Population. All of the data was in the public domain.


     The mapping of data sources to countries is as follows :

	      U.S. Census Bureau : U.S.A. and Puerto Rico, Alaska, and  US Territories.

	      United Nations Global Resource Information Database (UNGRID) : Europe and Russia.

	      Diva - GIS : Rest of the World (Mexico, South America, Africa, Asia)

U.S. Census Bureau

of Excel spreahsheets.

 UNITED NATIONS GLOBAL RESOURCE INFORMATION DATABASE (GRID) - Europe

      This is the main source of our data for Europe. It includes area and population for each location.

 UNEP/GRID (and any other sources mentioned in documentation of the data provided) as data furnisher(s). For data sets not available 'on-line', requests made by non-commercial and non-private persons (i.e. those
 with no affiliation) will be filled at no cost, but will depend on data availability, UNEP/GRID workload and the nature of the data set being requested. Requests will be queued with priority given to those related to joint 
activities with UNEP programme areas and other UN agencies. Data sets with a "restricted access" rating will not be distributed; however, information about such data sets, including the distributor's name, will be sent 
to eligible organisations upon request.

                          Users of data sets supplied through UNEP/GRID are requested to incorporate in output products and reports acknowledgements to the originator of the data and to the fact that they were acquired
