- Scale-dependent
viewing. AreaNav ensures that maps are always clear and
easy to read by turning on or off layers or altering their
symbology depending on the map scale.
- Multiple
Map Navigation tools. Users can choose from a variety of
map navigation tools including Pan, Zoom, Zoom to UTM or
Lat./Long. Coordinates (screen
shot), Zoom to a Map Feature (e.g. Worcester County),
and Zoom to a User- Defined Bookmark (screen
shot).
- GPS
Synchronization. With the press of a button on the toolbar
the user is able to see their location displayed in real
time as a cross-hair on the map. Works with any GPS unit
that supports the NMEA protocol.
- Find
Map Features. This tool allows users to search for features
in any of the data layers on the map. For example, a user
could enter the string ATTLEBORO and return all records
that contain a reference to the town of Attleboro.
- Map
Query Tools. AreaNav provides two methods for getting more
information about a data layer. Users can either receive
information on all map layers in a particular location via
the Information Tool or they can 'mouse over' a feature
and display a preset field when with the Map Tips
function.
-
Multiple raster images are supported including Color Orthophotos,
USGS Topographic Quadrangles and NOAA Charts.

GIS
stands for Geographic Information System
and briefly, refers to a combination of computer programming
and data which allows one to view, manipulate and attach
information to a series of map layers representing different
subjects or themes. The core picture of a GIS is a series
of stacked maps where one can easily juxtapose available
information for a given area.
GPS
stands for Global Positioning System and refers
to a satellite system which, with the appropriate receivers,
allows one to locate oneself geographically, frequently
with an accuracy of a few meters.
