Argh Help!!

[Horgy]

Zorcan,
I spent all afternoon going over the contours on an OS map in Paintbrush, and now i'm trying to register the terrain in TSTF, BUT it generates an error message when i put in the co-ordinates - Terrain cannot be more than 80kms in width of something...

I'm using the OS grid for input, and the following coords..

1) 490000 / 730000
2) 500000 / 730000
3) 490000 / 740000

Now they are a kilometre triangle, so what am i doing wrong?

James

P.S. Do you have MSN? If so can you add me, Horgy@Hotmail.com

[Zorcan]

The values you've quoted look to have too many noughts. If you're working with a 1 KM grid then respective axes values should only differ by 1000.

[Horgy]

What would i put in the boxes then, just subtract a zero from the end of each value?

James

[Zorcan]

James,

Simplest way is to tak ethe (2 or 3 digit) number as it appears on the OS map and add "000" to the end.

The direct answer to your question is "probably" - it depends on the location as to how many digits there are altogether in each coordinate.

[Horgy]

Found it, had an extra nought!

Now if only the bank could make that sort of error

James

[Horgy]

OK just one more thing, I made a 5 metre error on my contours. Now after drawing all my contours out, i dont want to do them all again, so to avoid these cliffs i have how do i drop the ENTIRE terrain by 5 metres?

James

[Zorcan]

James,

TSTF doesn't have any facility to do this - yet

One solution is to disregard the problem - just continue with this 5 metre offset. you won't see any difference in the route.

Does anyone else feel that moving a terrain up or down in height would be useful ?

[Horgy]

See the problem i'm having is with the rivers, because the terrain is at 0 already I cant move it down, the RE wont take a negative integer. ANy bright ideas on how I get my rivers to show?

James

[Zorcan]

James,

Are you saying that RE won't accept a negative value for water heights ?

It certainly will accept negative terrain heights - my standard approach for creating rivers is to set the river bed 20 or 40 metres below the shorline height, which usual means a sunstantially negative height.

I must confess I've never tried to set water levels of less than 0. Can anyone else comment on this ?

I will add an offset facility to the next release of TSTF, so that you can raise or lower the entire terrain.

In the meantime, I can't offer any way around this - sorry

[Horgy]

OK i'll wait til then.

Cheers
James

I've set a water height of -1 without any problems in RE.

[Horgy]

Thats all very well, but i cant set the land below that! Which is annoying. How long do you think til next version Zorcan?

James

[Horgy]

Bump - Whens the next version?

James

[Zorcan]

James,

Let's be clear as to your problem.

Is it that you can't set negative terrain heights or negative water heights ?

TSTF will set ANY level of terrain height, both positive and negative. When first setting up a new terrian, set the appropriate minimum negative height level, then simply use the height controls to adjust it for each contour.

[Horgy]

Well, my route runs near to the river Thames, and so the land along there is at 0 (as it said on my Map) So i set it at that in TSTF and now the RE wont let me lower it to create the river itself. I want to offset the entire terrain by about 2-5 metres so I can dig out the rivers!
