THE GISMO MAP VISUALIZATION TOOL -- CONTRACT
- Primary Requirements
- Secondary Requirements
- Tertiary Requirements
This project's goal is to develop a data visualization tool for terrain
maps: specifically, a GUI for manipulating and viewing maps of the North
Shore Mountains near Vancouver. Already provided for the terrain viewer
will be a general, thumbnail map of the area in interest (in this case,
the North Shore Mountains). Also provided will be topographical data of
the region's elevations, as expressed in three-space coordinates.
The job of the visualization tool is to provide a graphical user interface
for the viewing, in topographical detail, of any arbitrary subregion of
the general map whose dimensions the user will determine. The tool will
use the topographical data to construct a terrain map of this subregion.
The map will express elevations by using a system of gradated colors.
Ideally, this software will be extended for use in viewing maps not just
of the Vancouver area but also of any area, whose general map and corresponding
topographical data have been provided.
The party of Chris Arrington, Kirk Boyd, Jeff McLamb, Kwan Skinner,
and Brad Timmers shall be hereafter referred to collectively as "the
contractor". The contractor hereby agrees to design and provide a map
development tool that fulfills all Primary Requirements
given below. Upon completion, the software shall be delivered
to the client no later than May 1st, 2000.
In the event that the project is finished ahead of time, the
contractor agrees to fulfill as many
Secondary Requirements as possible;
and should those be finished with time to spare, the contractor will
fulfill as many Tertiary Requirements
The visualization tool must work for the map and data of Vancouver
provided by the client.
- The terrain maps of the subregions chosen by the user must give
an aerial perspective.
- The maps must also use a system of gradated colors to show differences
in elevation of terrain.
- There must be a feature that allows the user to view the chosen
subregion with its z-coordinates scaled by an arbitrary factor; that
is to say, the user may choose to double or triple all z-coordinates,
so as to bring out more clearly the differences in elevation on the
- The programming must be done in some language which can run C programs
provided by the client.
- The user will be able to provide an arbitrary map and topographical
data in either UTM coordinates (three-space) or the U.S. standard format.
- In addition to viewing a subregion from an aerial perspective, the
user will also be able to view it from a 3D perspective.
- The user will be able to select for himself the colors used in showing
- Maps can be viewed with the head-mount displays (HMDs) in the UNC
Dr. Jack Snoeyink shall be hereafter referred to as the "client". The
client hereby agrees to provide the contractors with the following
- Map and data for the North Shore Mountains of Vancouver
- C program for triangulating data points
In addition to those resources provided by the client, the
following will be needed:
- GUI software such as FLTK, Tcl/TK, or GLUI
- OpenGL software
- Microsoft Project
- Algorithm which constructs terrain maps from data points may be
too slow to be practical.
- Set of data points may require more memory than is practical;
some data points may need to be sacrificed, at the expense of
- Data for Vancouver area and other areas may not be available in
time for project's completion!
