Abstract:
The Original Grids of the Gridded Bird Species Distribution of the Americas are converted 1- kilometer grid cell data in the Geographic Coordinate System (GCS) that cover North America, South America and the Caribbean Islands. The input vector data were created by a consortium led by Natureserve. The grids are produced by the Columbia University Center for International Earth Science Information ... Network (CIESIN). The purpose is provide a gridded version of existing vector maps of bird species distribution at 1- kilometer spatial resolution, which in turn can be used in modeling efforts, wildlife conservation planning, natural resource management, policy-making, biodiversity studies and human-environment interactions.
The data in Band Interleaved by Line (BIL) format are available from the NASA Socioeconomic Data and Applications Center (SEDAC).
Purpose:
To provide a gridded version of existing vector maps of bird species distribution at 1- kilometer that preserves the original coding (1=Extant, 2= Possibly present, 3=Probably extinct, 4=Extinct, 5=Extirpated purposely, 6=Occurs on indicated island chain, and 7=Subfossil/fossil).
Quality
The records of the Emergency Events Database (EM-DAT), collected over a 20 year period from 1981 to 2000, provide regional, hazard-specific mortality and economic loss rates. A crude estimation of the global earthquake hazard mortality is developed using the EM-DAT regional mortality rates, population distributions from Gridded Population of the World, Version 3 (GPWv3), and frequency/distribution ... data from Global Earthquake Hazard Distribution-peak ground acceleration. To better reflect the confidence associated with the result, mortality figures are classified into deciles, 10 classes of an approximately equal number of grid cells of increasing mortality (item Value). Building upon a methodology developed by Sachs et al. (2003), a Gross Domestic Product (GDP) value (US$, 2000, purchase power parity adjusted (PPP)) is estimated for each grid cell. The process begins by determining the contribution of each subnational unit to national GDP using data of varied origin. The ratio of the subnational production to the national GDP is the contribution ratio. To ensure uniformity between countries, these contribution ratios are utilized with published World Bank estimates of GDP.
Once a standardized version of subnational GDP has been calculated, this value is further divided by the total population within the subnational unit. This subnational, per-person GDP value is multiplied by the grid cell population density to determine a GDP value for the grid cell. The GDP values presented in this dataset (item Gdpvalue) are not projections of impacted GDP, but rather the estimates of GDP that serve as a baseline for estimating hazard impacts. Furthermore, Gdpvalue is indicative of the GDP associated with each of the hazard risk deciles and not the individual grid cell.
Estimating the agricultural GDP (item Agvalue) follows a process similar to GDP. The amount of agricultural GDP is derived at the subnational unit using available data of various origins.
