do I have to ‘Zoom In’ to see more data?
display of many of the map layers in SalmonScape are
scale dependent. For example, the Hydro layer which was
developed from large scale (lots of detail) maps and
orthophotos would paint the state almost blue if viewed
statewide and would be pretty meaningless. Also, the
volume of data that ArcIMS would have to process to service
your request would be very large and would slow down
the display. To avoid these problems, you cannot see ‘Hydro
(1:24,000)’ in the layers list until you zoom into
a display area at a scale of 1:310,000 or larger of
a WRIA . You can determine what your ‘reference
by referencing the information along the bottom left
some cases, display of certain layers may be turned off
if you zoom in to a very small area. For example, shaded
relief and orthophotos may not be available if the display
scale would ‘pixilate’ the image (i.e. the
image becomes very grainy or boxy).
