SPATIAL SCIENCESpatial Science – the science relating to spatial data
measurement, collection, storage, analysis and visualization
Strait of Magellan – Magellan 1630http://www.victory-cruises.com/magellan.html

THE CONNECTOR Geography - X, Y, Z, T
X, Y, Z – based on an Earth Centre (where ever that is!)
T – intimately connected to x, y, z (Einstein) but so important in the Biodiversity record

Global Navigation Satellite Systems (GNSS)
All systems utilize the concept of trilateration to determine X,Y, Z position (with respect to an Earth centre) by measuring time (distance / time) from a series of orbiting satellites.
Trilateration: determinationof position from 3 or moredistances – not triangulation

GNSSGNSS – Global Navigation Satellite Systems
A series of satellite constellations utilized for Earth positioning. These include:
• Global Positioning System (GPS) – USA• Globalnaya Navigatsionnaya Sputnikovaya Sistema
(GLONASS) – Russia• Quasi-Zenith Satellite System (QZSS) – Japan• Galileo – European Union• BeiDou (Compass) Navigation Satellite System – China• Indian Regional Navigation Satellite System (IRNSS) –

GNSSThe number of GNSS satellites will increase from
Increase in GNSS frequencies (provides for ionosphereicdelay modelling)
Provision of a permanent “differential” signal (DGNSS)
….. will lead to cm (X,Y, Z) precision in small mobile devices
The benefits to biodiversity site recordingare immense

REMOTE SENSING
Digital images and subsequent computer analysis of our Earth from space orbiting satellites.
Provide daily low spatial resolution images of whole planet
Provide high spatial resolution (0.5 – 2m) images of most of the planet every few days
Hyperspectral images provide large number of spectral samples but, at this stage, at lower spatial resolutions from space. From the air they enable veg species mapping
Aerial UAV with sensors now provide very high resolution (cm) multi-spectral imagery of any ground location

Helicopters, Quadrocopters, Hexacopters and Planes – combined with DGNSS, Inertial Navigation Units (INU) and micro-imaging sensors ….. Providing super high resolution multispectral imaging of biodiversity sites, controlled by the site recorder.
