- To GIS and computer graphics users,
-
- I am currently researching past and present applications
- of the Triangulated Irregular Network (TIN). A TIN is a set of
- irregularly spaced (x,y,z) data points from a surface which
- have been triangulated in the x-y plane.
-
- While the TIN has found most use within GIS and
- cartography, I am also interested in finding its other
- applications.
-
- If this topic is related to past or present work you
- have/are undertaking could you please answer the following
- survey and reply as soon as possible.
-
- The findings will be presented in a technical report
- available from my site using anonymous FTP in
- November/December 1992.
-
- Thankyou in advance,
- Timothy Telcik.

- TIN SURVEY
- ~~~~~~~~~~
-
- NOTE: The word TIN may be interchanged with some other surface
- modelling variant that uses triangular elements.
-
-
- 1) Do you perform Digital Terrain Modelling or surface
- modelling using a TIN ?
-
-
-
-
- 2) For what application(s) do you use the TIN ?
-
- Examples:
-
- - watershed/drainage analysis
- - viewscape/viewshed analysis
- - contouring
- - slope and aspect analysis
- - representing human figures
-
-
-
- 3) Is this processing performed with commercial, in-house,
- public domain, or shareware software ?
-
- If yes,
- - what is the name of the software ?
- - who produces the software (company or person) ?
- - what is the producer's address (air mail/Email) ?
- - what is its current cost ? (US$, AUS$ etc.)
- - does it provide support (interchange) with similar
- packages ?
- - is there any important information about this software
- which needs mention (eg. special hardware platform) ?
-
-
-
-
- 4) Has the software or your work been discussed in any
- journal, conference, book etc. ?
-
- If yes, please provide a full reference.
-
- Examples:
-
- Kumler, M.P. (1990) A quantitative comparison of regular
- and irregular digital terrain models. In:
- Proceedings of GIS/LIS '90. Anaheim, California.
-
- - discusses advantages of TIN over grid for surface
- representation using ARC/INFO
-
-
- Turnbull, M., I. McAulay and R.A. McLaren (1990) The role
- of terrain modelling in computer-aided landscape
- design. In: Terrain Modelling in Surveying and Civil
- Engineering (G. Petrie and T.J.M. Kennie eds.), pp.
- 263 - 276. Whittles: Latheronwheel, Caithness.
-
- - discusses the CAVIA (Computer-Aided Visual Impact
- Analysis) software which uses TIN and grid for
- viewscape/line of sight analysis
-
-
-
-
- 5) Is your work for commercial, government, private or other
- gain (eg. state forestry program, resource allocation, special
- FX for film) ?
