All surveyed Hydrographic statistical figures are recorded and stored in the database following the individual or collective use of the following tools and equipment:
1. D-GPS: a differential GPS module used to determine mid-sea locations.
2. Echo Sounder: a sonar-like device that emits sound waves below a ship and measures the time that passes until the ocean floor reflects the wave, thus determining the depth of the water and variations in wave height.
3. Ceilometers: devices that measure sea water temperature through laser-pointed thermometers, salinity (salt level) and particulate density through filters, and cloud height proximity to sea level.
4. Heave and Compensator: devices that measure the lateral roll and longitudinal tilt (pitch) of a ship, providing the captain and crew with data crucial to avoid capsizing and sinking.
5. Tide Gauge: a device that measures levels of high and low tides, with a clock giving time readings for preset water levels.
6. Gyrocompass: an electronic compass that always point to True North (the geographic pole region) since it is unaffected by magnetic fields or ferrous metals (containing iron).
· The completion of surveying 64.5% of
· Publishing 11 marine maps out of the originally intended 12 to cover all territorial waters.
· Obtaining the international norm (WGS 84 Datum) for 8 marine maps.
· The annual publication of tide tables and a Marine Feature Atlas every 5 years or whenever a major update is completed.
· Producing a weekly digital map for a specific marine location.
· Producing local maritime maps via (CARIS HOM and CARIS GIS).
· The completion of 8 digital marine maps using CARIS GIS until 2006.
· The completion of all marine map surveyed data entry in the 1st half of 2007 to enable swift production of specific maps when required.
