The document discusses the Geobricks framework, an open source modular architecture for building geospatial web services and applications. It consists of libraries, REST services, and backend modules. The architecture uses a 3-tier service oriented design. Example modules allow downloading data from various sources, processing it using OGR and GDAL, and distributing outputs through OGC standards and other methods. A 2008 Afghanistan drought case study demonstrates acquiring MODIS and TRMM data, processing it to show anomalies in temperature, rainfall, NDVI and other outputs to analyze the drought's impacts.

CASE STUDY

10. 2008 AFGHANISTAN DROUGHT
CASE STUDY
Well-below normal rainfall and winter
snowfall across the majority of Afghanistan
during late 2007 and early 2008 have led to
the worst drought conditions of the decade
Wheat production dropped by 60% and flour
import increased by 34%

11. DATA ACQUISITION
MODULES: DOWNLOADER, DATA WRAPPERS
TRMM: Rainfalls, Daily, 0.25deg
MOD13A1: Vegetation, 16-Day, 500m
MOD13A3: Vegetation, Monthly, 1km
MYD11C3: Temperature, Monthly, 0.05deg
MOD16: Evapotranspiration, 8-Day, 1km
