<div dir="ltr">If someone is working on this area, then it would be good to allow the minimum and maximum altitude to be used for the colour range to be specified in maps. I currently do this via a hack in my maps, including a scrap containing two artificial fixed survey stations at the min. and max. altitudes I want the map to use for colouring. Provided the rest of the scraps in the map are in this range then the entire map is coloured the same regardless of which scraps I include. So I can generate a map of part of the cave with the same colours as the map of the entire cave. Otherwise maps of small areas of the cave get coloured with very different scrap colours due to the small altitude range of the scraps in the map.<div><br></div><div>Footleg</div></div><div class="gmail_extra"><br><div class="gmail_quote">On 5 January 2015 at 22:40, Bruce <span dir="ltr"><<a href="mailto:bruce@tomo.co.nz" target="_blank">bruce@tomo.co.nz</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
