Can
I view the internet mapping sites with a Mac?

Pop-up
Blockers. When I click on an activity I don't get a map. You
may have a Pop-Up Blocker installed on your browser. You need to disable
this feature for the activities to come up in a separate window. It is not
necessary to "uninstall" the pop-up blocker, just disable it while
using the site. Yahoo, Google, and many other internet companies provide
free pop-up blockers that you (or someone else) may have installed on your
computer. If you have a pop-up blocker installed there is usually a button
or icon on the toolbar that you can use to enable or disable pop-up
windows. Make sure to "disable" this feature.
What
do the buttons on the left side of the screen mean? Hold your cursor over a button for about a second and a label
will pop up (also will tell you in the lower left of the screen).
When
I click on the Worksheet and Overview links I don’t get anything.
You must have Adobe Acrobat Reader on your computer.

Why
does the Activity map load so slowly? The
speed at which the map will load depends on your Internet connection.
If you are using a dial-up modem, the map will load slowly.
The
Activity map seems to be “hanging,” not just loading slowly, what do I do? Occasionally, this can happen.
Just close the Internet Mapping window that appears to be stuck and
re-click on the Activity. That
usually fixes the problem.
Why
don’t the “Back” and “Refresh” buttons on my web browser work on
the map windows? Notice that when you click on
an Activity, the map opens in a new window.
The software you're using in that window is ESRI’s ArcIMS, which doesn’t allow
you to go back to a previous window or refresh the map using buttons on Internet Explorer or
Netscape. To refresh or reload the map, click the REFRESH MAP button on
ArcIMS.
So
how do I get back to this website to find more information and activities?
After you open any Internet mapping activity, ALWAYS
keep your original window from this website (the one listing the activities) open or minimized,
and you can go back to it whenever you need.
Why didn't the map change when I
added or subtracted layers? Any
time you change what
map layers are visible or not visible, you need to click the REFRESH MAP button in the lower right to reload
the map.
I
see a list of “Layers” but I don’t see a Legend for the layers—how do I
get the Legend? Use the Toggle Between Legend and
LayerList button (upper-left button).
I’m
trying to use the Identify button, but I can’t seem to get any results.
How do I fix this? First, make sure that the layer you want to identify is BOTH Visible
AND Active (and Refresh Map).
If you are still having problems try to click directly on the
feature—in the middle or slightly to the upper-left of the feature's center.
Drawing a Zoom In box to the area you’re interested in can also
help. On some maps, it is possible to get multiple
results for one Identify click.
When
I use the Identify button I get a bunch of weird results in the bottom window.
How do I know what the different column names mean?
Most
field names are intuitive: for example, POP1880 means population 1880.
We also have a document that describes each layer and many of
the field/column names. Click on:
What
You Can Map.
After
using the Measure tool, how do I get rid of all those red lines on the
map? Click on the Clear Selection
button.
Can I change how the map is
formatted or positioned when I print it out? No,
you cannot make changes. If you
have ArcExplorer (see below), you can export the map out as a basic JPEG and
then work with it in an illustration software package.
Why
can’t I create my own categories and colors on the map?
This version of ArcIMS is the simplest and requires no special
Internet Explorer or Netscape add-ons or applets. But
this means the end user cannot do much customizing.
If you would like to do more with the data, please e-mail us and we will
provide a CD that includes over 80 GIS layers, free copies of ArcExplorer for
both Mac and PC, an installation
guide, a PDF manual on how to use ArcExplorer, and samples of the activities found on this website.
I
don't see the answer to my problem here. Help! See
the e-mail addresses below.
How
do I find out more about the technical side of this project?
Send an e-mail to david.diggs@unco.edu
if you'd like to know more about the modifications made to the ArcIMS programs
that were made to get the maps to look as they do.
I've
got some ideas for new activities or ways to improve the ones online. How
can I help?
Any suggestions for improvement are welcome. Send your ideas to phil.klein@unco.edu
-- and we thank you.
