A straightforward and high-parallelized method is applied to investigate parallel
performance of five categories of typical algorithms in remote sensing based mapping on
two multi-core computers.

Varying grid resolution of Lidar-derived DEMs showed that watershed boundaries and
upslope accumulation areas were most dependent on DEM processing; their utility in
watershed analyses may be compromised if the best DEM resolution is not chosen for a
given study site.

Ohio’s capital city, Columbus, is situated along the Scioto
River and is one of the fastest growing cities in the
state. In 1986, the municipal population was estimated
at 600,000. The latest population estimate for Columbus
from the U.S. Census Bureau is over 820,000.
These two images show Columbus and surrounding
areas in 1986 and again in 2014. The second image
shows the gray urban areas expanding into previous
agricultural land, which is indicated by green patchy
areas. The bright areas throughout the city are retail and
industrial centers. The dark blue spots along the river in
the southern part of the city are wastewater treatment
ponds and other ponds associated with local sand and
gravel quarries.
The historical record provided by Landsat images can be
a useful tool for city managers, planners, and scientists
who are monitoring and documenting the changes to
Earth’s land cover caused by urban expansion.
