Background to RIFA RemoteSensing Project

Red Imported Fire Ant so what??:

RIFA is a native South American ant species

Introduced to South East QLD (Brisbane) in 2001. Possibly brought in byship.

Can be dangerous/lethal to humans and livestock

Destroys agricultural lands and pastures

Able to spread via flight

Easily spread by moving earth and equipment between areas

Potential for RIFA to be moved to other towns, cities and/or states ie.potential national biological threat.

Background to RIFA RemoteSensing Project

Red Imported Fire Ant so what??:

In 2001 there were 1000s of nests in the Brisbane area (300 000ha)

Today there are only a few hundred known nests in control zone

Control zone grows by 10%/annum

One of issues to achieving full eradication is defining the outer extents of

the biosecurity control zone:

Where might there be viable ant colonies that we have not found yet?

How far outside the control zone should we be looking?

How will the outer farmland areas be monitored?

Manually 1ha/person/day

Initial Trials

Outline were appointed by BSQ in 2008 to research and field test anintegrated multispectral + thermal system for use inidentifying/mapping RIFA nests from the air:

Utilise existing Outline multispectral camera technology

Loosely coupled thermal

Fly known infested sites

Utilise helicopter platform to allow flying low enough and slow enough to

achieve required thermal resolution Identify limitations of system

Proof of Concept Camera System

Initial Trials

Conducted trials simulating high resolution imagery:

flying at 200 to 300ft AGL

Small sites of 50 to 100ha

Validation

Target nest sites visible at simulated resolution of 3 4cm RGB/NIR and6-8cm thermal

Challenges

Manual rectification and alignment of loosely coupled Thermal images

Poor band alignment

Low helicopter flying heights (~200ft) Convert to large scale operations data and personnel intensive

New Camera Design

Concept proposed to redesign current system to fully integrate highresolution thermal capability

Proposed Specification:

Colour (RGB) 3cm resolution from 500+ft AGL Near Infra-Red (NIR) 3cm resolution from 500+ft AGL

Thermal 6cm resolution from 500+ft AGL

MS Bands and Thermal Bands co-registered

Onward.

Deploy two Outline systems to the RIFA project for the2012 Brisbane flying season (May to September)

Aim to capture, process and deliver approx 75 000ha of3cm RGB/NIR and 6cm thermal imagery per camera over6 months.

Onward.

Explore alternative applications of thetechnology:

Post-fire scar and remnant fire hotspot mapping

Irrigation monitoring Urban heat / insulation mapping

Ferrel animal (kangaroos, pigs, camels) surveys
