abstract = "Drainage network is basic information for developing applications
involving surface and underground water resources. The
determination of good quality drainage network can be extracted
from altimetry grids with high or at least medium resolution. They
can be used for studies in small and large watersheds. When the
target is a large watershed, high and medium resolutions are not
adequate. The grid resolution should be decreased and consequently
the drainage network must be extracted for this new resolution.
This mapping can be done in two ways. The first possibility is to
extract the drainage network from the new grid altimetry. The
second one is to define the new drainage network from the original
drainage. In this work, the second possibility was implemented to
provide the best quality drainage. The method called Priority
First SearchPFS used by TerraHidro for extracting drainage from
Shuttle Radar Topography Mission (SRTM) with 90 m of horizontal
resolution, is described. The Upscaling process, responsible to
convert high resolution drainage network to low resolution
drainage network, is detailed and results are presented to show
the effectiveness of the Upscaling process contained in
TerraHidro. The distributed hydrologic models employed in
underground waters using in many cases the network of surface
drainage as basic information.",
