Hmm, it does take a bit of work.GPSGuided wrote:How did you generate that in such smoothness and detail?

The back of the current edition Topo from LPI is an equally sized satellite image. No room to write.

If you could get in 4 4 x 25 cm strips on an A4 landscape page, you could fit the entire AAWT on 2 double sided A4 pieces of paper. This would give you 1600 m vertical variation per strip, which should be fine, although you would need to alter the start and end scale to cope with the low points of Thompson River and the Mita Mita, and also the peaks of the Main Range.
1 cm to 1 km would take 4 double sided A4 pages.
GE is OK as far as it goes but a major limitation (IMO) is that the scale and ratio are not easily controlled/set.frenchy_84 wrote:ive just discovered how easy it is to create a vertical profile in Google earth, simply create a path than right click on it for vertical profile

The slope or gradient of a line can be specified as a ratio (V:H) but can also be specified in degrees (or even radians). My point was that to be able to look at profiles and get a sense of the steepness of slopes, you need to have the same ratio (as defined in this context) across the profiles.frenchy_84 wrote:The slope of a line is specified as a ratio

The slope of a line is specified as a ratio. The scale of a profile plan can be specified with both a horizontal and vertical scale.

The above profile has a V:H ratio of 1:4.5 and a scale of 1:8,200
