determine erosion and accessibility areas. We
can also drape the aerial photography and
create movies and animations.
From time to time, this data is updated or
modified, so city executives can visualize the
changes taking place within the City of Austin.
The Bentley solutions can display both raster
and vector data in a common view, which helps
executives and project managers better under-
stand the impact of new projects on the city. ;
The goal of this project was to create a comprehensive program of aerial photography
for the City of Austin.
One of the sub-projects was to combine
some of the more visible geographic features
with the aerial photography, starting with an
area of the Colorado River that has been
dammed to control flooding downstream.
Twenty-one LIDAR (light detection and ranging) point files were combined and a tin
model was created in Bentley’s GEOPAK.
GEOPAK handled millions of points of triangulation data. Being able to handle this many
vertices on the screen is amazing!
We can now visualize any information we
need, from thematic maps to slope maps, to

System demands were calculated based on

into WaterCAD. An initial simulation was
developed to determine pressures throughout the distribution system, and a second to

pressures to locate leaks and pipe breaks.
