ArcIMS
ArcIMS requires that
you have a 5.0 or greater web browser. We recommend that you have a 56k
connection, 200Mhz cpu and 64mb RAM.
ArcIMS, or Arc Internet
Map Server, brings the power of of geographical information systems(GIS)
into your computer via a web browser. GIS is an adaptation of database
technology, but specifically applied to spatial relationships. It allows
you to view the relationships of data in geographic prospective, and to
create new data sets based on those relations. The Bureau of Economic
Geology has streamlined this application to easily serve our extensive
GIS data collection.
These ArcIMS pages
have a tool bar on the left side of the window for manipulating map appearance
and data. These maps are constructed from layers of geospatial data sets.
To view a list of layers press the tool button on the very top left-hand
side, which resembles a text icon. A text list of layers with check boxes
and radio buttons should appear. The layers with checks next to them are
drawn on the map, the ones without a check are invisible. To activate
hidden layers, click a check mark next to the desired layer and then scroll
to the bottom of that frame and click "Refresh Map". The new layer(s)
should then appear. It is also possible to turn off layers in the same
fashion.
You can also use some
of the geographical information systems (GIS) features that are found
in the tool bar on the left side of the screen. For a description of each
tool leave your mouse cursor motionless over the button for a few seconds
and its name should pop up. These tools give the user many options, including
the ability to navigate about the map zooming in and out. It also has
special tools for searching, comparing and finding spatial information
about selected features. To use these tools it is necessary to make the
layer you are interested in active. This option is also found on the right
side of the screen, it appears as the radio button next to each layer.
The beach profiles
on each ArcIMS webpage are hotlinked to web pages with profile graphs
and data. When you are in the ArcIMS web page, use the tool resembling
the lightning bolt to open these web pages. Another tool that resembles
an i can be used to identify an area and it gives the link to the data.
The beach profiles layer must be active to use this option.
