Mapping Census 2010 Illustrates Major Changes in US Population

Mapping Census 2010: The Geography of American Change New Esri Atlas Compares Maps from 2000 and 2010 Censuses

Mapping Census 2010: The Geography of American Change from Esri Press depicts the extraordinary changes in the American population over the past decade. Extracted from the data collected by the US Census Bureau in 2010, the new maps are displayed side by side with maps created after the 2000 census.

Using choropleth maps that are shaded in proportion to the change in statistical variable, the atlas is divided into four sections and compares variances in population shifts, household occupants, housing ownership, and ethnic diversity between 2000 and 2010.

Section 1 includes snapshots of the total US population in 2000 and 2010 without reference to race or ethnicity. Section 2 is a series of maps showing the state of housing and households in America over that decade. Section 3 maps minority populations and diversity using data from Census 2000 and Census 2010. Section 4 presents different views of the basic race and ethnicity data collected by the US Census.

“The 10 years since the previous census was a decade fraught with unease in global security, natural disasters, and economic turmoil,” says Jack Dangermond, Esri president. “How has America changed demographically and geographically in these difficult times? Mapping Census 2010: The Geography of American Change sheds light on this and other questions about our population.”

Accelerating Batch Processing of Spatial Raster Analysis using GPU

Computers & GeosciencesComputers & Geosciences, Volume 45, August 2012, Pages 212–220

Mathias Steinbach, Reinhard Hemmerling

“Batch processing of raster data performed by geographic information systems (GIS) is a time consuming procedure. Modern high performance GPUs are able to perform hundreds of arithmetical operations in parallel. These GPUs can help to reduce the computing time of such operations. In addition, most of the commonly used raster operations are I/O-bounded. Memory transfer between hard disk and RAM takes up more time than computations. The scope of this paper is to present an efficient two-level caching strategy for raster data and an acceleration of selected raster operations using the GPU, which were implemented as a plugin for the open source software GRASS. An example data flow based on a real world use-case will be presented and the obtainable and practically expectable speedup will be measured and discussed.”
