Map IT connects to any GPS simply by specifying the port number of the GPS
receiver of the
tablet pc.
While conducting field work, the data collector
can display the current ground position on the tablet pc's map display, in
real time. The GPS settings window of the Map IT
interface conveys information relative to the path of the data collector (speed
and direction) and to the status of the satellites.
Map IT calculates the average fix received from the GPS in a time interval
specified by the user, considerably improving the data precision.
A coordinate system different from the WGS84 used as the standard by all GPS
data collectors may be defined (also adopting a False-East/False-North
system). The data regarding the position obtained from satellites is
immediately compatible with the project with which you are working.
The Capture Point
command draws a point on the cartography in the exact position of the data
collector. This function is useful when you must accurately capture the
position of point elements.
You may capture GPS
coordinates while moving. In this case, Map IT offers the
possibility to choose whether to capture the path as points or arcs and to
set a spacial tolerance (in meters) and time tolerance (in seconds) for
which to capture the data. In addiction, it is possible to capture vertices of
arcs and polygons manually.
 All the graphic objects captured by the GPS becomes
active elements of the project.
Map IT can carry out some post-processing elaborations as
concatenating points captured by GPS in the same layer or georeferencing documents created during a surveying campaign. Imagine having mapped an
outcrop taking structural measurement with a spreadsheet and photos with a
digitalcamera, written a few annotations in a text file or recorded voice
notes. When returning, Map IT automatically positions the documents on the
cartography in the exact point in which the files were created, taking
advantage of the time/date information of the files and the position data
recorded by the GPS.
