Dimensionally accurate elevation and planview drawings of the
proposed construction. AutoCAD format preferred
Good survey data of
surrounding terrain, especially if there is a lot of elevation
change. On some large projects, USGS data has been used, but
in cases where the same terrain has been re-surveyed, major
inaccuracies were seen in the USGS topography. Today, much
survey data in electronic form is natively three dimensional.
This makes it easy and inexpensive to import it into the computer
scene.
High resolution aerial
photos. The higher, the better. This makes it easy to
figure out what objects are in the foreground of our view,
especially trees and bushes, which can provide valuable view
mitigations.
Precise identification of
materials and colors will make the rendered view of your project
look like its supposed to look. Many manufactures have
pictures of their products on their web sites.
Exact location of camera
for each view. It is preferred that Videoscapes take the base
photographs with a high resolution, GPS enabled digital camera
(Nikon D200 with Garmin GPS). All relevant camera information,
such as lens focal length, tilt, and elevation should be recorded.
It is possible, more or less, to find the view of a picture with no
data, but when you consider the number of axes that have to be
reconstructed, there are three things to keep in mind: labor,
time, and expense.
