2. Goal of the Application
A Computer System has been developed
for the on-line capture, visualization,
transmission and storage of data measured by
the Mobile Unit sensors, with a robust
exceptions control which let us know the
cause of whatever misfunction that could
happen during a session.
SIG technology (ArcGisEngine -
ArcObjects) has been used for the
georeferenced visualization of the measures.

5. Equipment
The Mobile Unit UMA (Unidad Móvil Ambiental) is an off-road
vehicle, with all the instruments needed to make radiation
measurements “in-continuo” such us environmental equivalent
dose rate and environmental pollution caused by beta/gamma
emissions.
Instrumentation:
Ionization chamber and Geiger-Müller detector.
USB-connected to the Portable PC.
• 3 sodium iodure INa(TI) sensors:
Connected to a Netbook wich is Ethernet connected to the Portable PC.
• GPS:
USB-connected to the Portable PC.
• Portable PC:
It’s the core where all the instruments are connected. It controls the sampling parameters, the
co-ordination with the GPS. And it controls too, the beginning and end of a session.
The software which controls all the processes is installed here.
The georeferenced visualization of the measurements on a map takes place on it.

9. The GIS Viewer
Application created on Windows using ArcGis Engine
(ArcGis 9.3.1) - ArcObjects on Visual Basic .Net.
It creates three resource areas: MapControl; TOC Control
and Tools Control.
It uses cartography provided by IGN: raster maps from
MTN-25 (Mapa Topográfico Nacional 1:25000) for the interest
areas.

11. The GIS Viewer - Functionality
The GIS Viewer extracts the (x,y) position from GPS.
• Compare the position with the cartography areas and
decides which must be loaded.
• Then, the raster cartography from IGN must be projected for
fitting with the GPS projection.
• Measures from the sensors and GPS are passed to the viewer
from the control system and the geographic viewer creates a
file, then a (x,y) event theme and, eventually, an entry in the
TOC, with a different colour code for each sensor, and a
different color when the sensor threshold is overcome.

12. The GIS Viewer - Functionality
• A bubble control has been created for accessing the
points shapefile information: variable value, sensor type,
value of the projected coordinates ...
• As the mobile unit goes on, the position is centered in
the GIS viewer, on the raster map, and the (x,y) files are re-
written and the event themes re-painted.

13. System Capabilities
Customizing the measurements campaign:
Deciding which sensor will be considered, the calibration files and the alert and
alarm values.
Testing the correct operation of both sensors and
communications.
Monitoring graphically the measurement process in real time:
Using the GIS module which shows the georeferenced measures on a map.
Checking the overcoming of threshold values and alerting about
it both at the GIS and the alphanumerical viewer.
Storing all the measures and the route of a campaign into a file.
Sending the alphanumerical data vía GPRS o vía satellite to a
centralized data warehouse.
Providing to CSN the access to the data warehouse.
