<br><font size=2 face="sans-serif">I am trying to plot all the caves over
a wide area (entire Matienzo expedition area) in Aven, so that I can generate
overlays for Googlemaps. One thing that is a problem with this is that
elevation detail is difficult to determine by colour due to the wide elevation
range of the caves (615m to 40m). What appears to happen is most of the
caves are pushed into the blue banding. Looking at the colour bar in Aven,
it appears that the blue zone takes up a lot of the elevation range, as
does the red zone. In the middle the bands for Orange, yellow, green are
fairly narrow. Would it be possible to extend the colour banding to include
purple at the bottom, and lessen the bias of the red and blue bands to
give better visual differentiation of passages at elevations in the middle
of the range?</font>
