Why you need Descartes for Terrain Modeling
•
STM is a revolutionary new
technology that enables highperformance display of digital terrain
models (DTMs) covering very large
areas and containing billions of
points
•
For viewing huge digital terrain
models at geospatial scale
Scalable Terrain Model (STM)
– City, Region, State, Country
•
Potential users
– Municipal, States, Federal agency
and government
– EPC working in GIS
– Large infrastructure project
Image courtesy Quebec City
• Show areas of the STM
visible from a point or
path
• Define a point on or
above the terrain
• Support multiple points
of view and paths
Viewshed Analysis – What is it?
• Improved design to meet
regional planning
requirements
Viewshed Analysis – Benefits?
• Drape linear element
directly on Scalable
Terrain Model
• Show location of
proposed road alignment
on existing terrain
• Show cross section of
terrain along alignment
Drape Elements – What is it?
• Produce visuals to
support design
understanding
Drape Elements – Benefits
• Extract Raster DEM
• Specify and area and
resolution
• Interoperability with other
GIS or visualization
STM – Raster DEM
• Convert contours to
MicroStation elements
• Enable editing
• Integration with other
DTM and GIS software
• Accurate plotting
STM – Contours
• Better integration with
civil and GIS
