System to facilitate the mapping and visualisation of glaciers
using of GPS data
In order to help complete my Umist main project I have decided to
put a work in progress onto my website.

Work Done |
Notes |
| 25/04/2003 |
- Fixed heightmap display.
- Added keyresses to rotate zoom and pan the image.
- Fixed a bug when displaying two or more visualisations in one session.
- Added some tool tip messages to improve usability.
- Added Validation routines to stop the system displaying empty datasets
|
The error with the display was due to the incorrect use of varible type integer to hold colour values. Image now displays better or in wireframe |
| 18/04/2003 |
- Woked out the methods for using a hieghtmap.
- Altered the code for heightmaps.
- Fixed a bug importing data.
|
The heightmaps method produces a much better visualisation there is still an error with the output though aking it difficult to see the object correctly |
| 11/04/2003 |
- Found A better Method for visualisation.
- Added percentge bars to the import so you know its working.
- Added the ability to manage surveys.
- Fixed the camera angle so old visualisation now displays.
|
Due to the nature of the data (its clumped in places sparse
in others) I have decided a better way to visualise would be to use a
grid format. I had seen teh height map method beofre but an artical in
geocomputation from an auther experimenting creating surface using
fortran and splines drove me to this conclusion |
| 28/03/2003 |
- Got a GL window to appear
- Data can now be injected into the survey
- Failed to get the data to display though :-(
|
I think im doing somethign wrong with the camera angle all I
get from the display is a red blob rather than a lot of triangles. I
think they are being displayed and the viewpoint is set too far out, but
when I move it forward everything disapears. Perhaps because the camera
passes through the visualisation object. |

- Fully Switch to visual basic
- Wrote the CSV import routine
- Added the ability to connect to a database
|
Im on the right track but behind schedual I need to do some
sort of visualisation soon, the tutorials from NEHE are helping but Im still stuck. |

- Met A Conroy, discussed switching to visual basic
- Arranged To meet Postgrade student to get help with project
|
Pros and cons of visual basic versus C++ |
|
| 14/02/2003 |
- Basic C++ Code
- Arranged To meet Postgrade student to get help with project
|
C++ code can be found Here |
