MEGIS is pleased to
provide a new, updated orthoviewer application. The original orthoviewer
application is to be retired within 3 weeks, likely on February 19. The
new orthoviewer includes all the imagery that is available via WMS, and the
ability to download image tiles for most imagery layers.
A few hints
(which may not have yet made it into the Help
system)...
Click on 'Zoom to a
Town' and you'll get a pick-list of towns to zoom to. It will zoom to the
town, highlight it for a few seconds and then draw your background. Your
selection will be saved in the 'Results' pane until you are
done.
To download image
tiles, expand the layer you want by clicking on the "+" sign next to it in
the "Map Contents" and turn on the "Index" layer. You will see the tile
index drawn over the imagery. Use the "Select image for download" tool
(the circle with the "i" in it) and click on a tile you want, then click on the
hyperlink returned to download it. Images will be either SID or JP2.
You currently cannot select multiple tiles to download, it's one at a
time.
Each "layer" is a
separate WMS layer, so if you turn them all on at once, you're going to be
waiting a while. For best performance, only do a few at a
time.
There is an idle
timeout for the application, if you are away from it for more than 10 minutes it
will cease functioning, you can 'refresh' to get it working again in a new
session.
MEGIS will keep both
the "old" and the "new" orthoviewers running until February 19. We would
be pleased to hear any feedback to help improve the new
orthoviewer.
(and thanks to Bob
Bistrais for whipping this together)
