Africa/Asia/Latin America Maize Research Atlas。
The series of Maize Research Atlas produced by CIMMYT's Natural Resources Group (NRG) and Maize Program, contain spatial data including climate, soils, elevation, population, land use and maize mega-environments for Sub-Saharan Africa, Southern Asia and all of Mexico, Central and South America. In addition, climate similarity maps for dozens of major maize research sites in each region are provided. All data are stored as ESRI shapefiles, and MapExplorer (v. 2.0) - developed by ESRI, UK, has been included for data display and query. Each Atlas provides a compendium of more than 150 layers of digital data on climate, soils, elevation, land use, population, and a range of maize-related information for the target region in a stand-alone, CD format.
