Remote Sensor Ecologist
Did I tell you about our latest UAS? It has 2.4Ghz spread spectrum, accelerator, gimbal, gyroscope inertial control system to take care of pitch roll and yaw, LiPo batteries, collecting true colour, IR, Hyperspectral and Lidar imagery!
(Eyes Glaze over)….. Er Cool – Can it tell me how much vegetation cover there is?
Error!
What are the Problems?Translation problem

Then went looking for:
“Push”

Then look for solution:
Problem“Pull”

This is what we (as Remote Sensors) like!
This is where we make a difference!
Knowledge and Wisdom allow us to affect positive change
Changes in managementReal world outcomes

Don’t care about the platform
![Page 12: Ecosystem science requirements for uas remote sensing](https://reader035.fdocuments.us/reader035/viewer/2022070519/58ecc3911a28ab9f538b468b/html5/thumbnails/12.jpg)
Or what is under the bonnet ( The Tech Specs)

But we do want “Oh, what a feeling!” because it “Just Works” and “Doesn’t Break”
![Page 14: Ecosystem science requirements for uas remote sensing](https://reader035.fdocuments.us/reader035/viewer/2022070519/58ecc3911a28ab9f538b468b/html5/thumbnails/14.jpg)
Not interested in processing steps

Remove technical complexity
(the Collinearity Equations give us nightmares)

Don’t make life harder in the field!
![Page 17: Ecosystem science requirements for uas remote sensing](https://reader035.fdocuments.us/reader035/viewer/2022070519/58ecc3911a28ab9f538b468b/html5/thumbnails/17.jpg)
A “good” Remote sensing journal (RSE) search for “UAS”
A “Good”methods based Ecology Journal search for “UAS”
Pls refer to Arko’s far more robust analysis.

Homework1. Befriend an
ecologist2. Ask them what
information that they need
3. Give it to them!
(Give the customer what they want/need- or better still actively collaborate)
![Page 19: Ecosystem science requirements for uas remote sensing](https://reader035.fdocuments.us/reader035/viewer/2022070519/58ecc3911a28ab9f538b468b/html5/thumbnails/19.jpg)
Another reason to adopt an ecologist!

All types of monitoring valid & ImportantAll need to work together for optimum results
I’ll focus on Surveillance monitoring
And it’s interaction with landscape monitoring
Because
• Know more about it• Provides a huge range of opportunities
for UAS – needs information that is needed that
you are well placed to provide!
![Page 21: Ecosystem science requirements for uas remote sensing](https://reader035.fdocuments.us/reader035/viewer/2022070519/58ecc3911a28ab9f538b468b/html5/thumbnails/21.jpg)
NOT
Because we want to know if there is a problem, but we don’t have the resources to have the fire
department everywhere all the time!

Ausplots• Standardised method and
data delivery• Continental in scale• Samples all environments• Wide range of variables
sampled• Collected in a RS friendly way• Wide range in Surveillance
information needs• Desire to future proof.• www.ausplots.org.au

So what is the Pull?What DO ecologists need?What opportunities does that provide UAS? /
Ecology: The study of the distribution, abundance and interactions of organisms
• What is it?• Where is it?
• How much of it is there?• What condition is it in?
• Composition• Function• Structure

So what are the Opportunities for UAS?
![Page 25: Ecosystem science requirements for uas remote sensing](https://reader035.fdocuments.us/reader035/viewer/2022070519/58ecc3911a28ab9f538b468b/html5/thumbnails/25.jpg)
OpportunitiesUAS ability to have Rapid revisit times
Provides a flexibility to meet timely needs not available at the same scale in the same time periods
Capture events as they are happeninge.g Fires, Flood and Crop disease
Short term change - Lower information content than field based survey, but also lower time of acquisition and hence $$
![Page 26: Ecosystem science requirements for uas remote sensing](https://reader035.fdocuments.us/reader035/viewer/2022070519/58ecc3911a28ab9f538b468b/html5/thumbnails/26.jpg)
Opportunities
More frequent re-visits in the context of surveillance monitoring- We’ll only be able to afford to collect field data at our
sites ~ 1x per decade- UAS can provide less information content (Overall cover
v’s cover per species) , but more frequently ( Every year or two) in a cheaper and more rapid way

OpportunitiesPatterns at the scale of the site – EG SASMDD0001

OpportunitiesInfo on Micro-topography – has a big influence on vegetation patterning
![Page 29: Ecosystem science requirements for uas remote sensing](https://reader035.fdocuments.us/reader035/viewer/2022070519/58ecc3911a28ab9f538b468b/html5/thumbnails/29.jpg)
OpportunitiesInformation on Vegetation Structure / HeightLots of examples over the past few days – Witnessed it being done with LEGO inside an hour and a half!

OpportunitiesUpscaling From Our good quality field data – Truth
To UAS data
To regional products
And Continental
And Global

Opportunities
Easy to use?
Consider this a challenge!
It’s not dead – It’s just resting!
![Page 32: Ecosystem science requirements for uas remote sensing](https://reader035.fdocuments.us/reader035/viewer/2022070519/58ecc3911a28ab9f538b468b/html5/thumbnails/32.jpg)
OpportunitiesAn opportunity to move from a research to an operational focus.
A Maturity challenge - Right on the cusp now?- Getting the final polish right can
take a while
Has the opportunity to be cost effective if full cost calculated and operationalised.

OpportunitiesFuture proof – The ability to re-process the data into the future as new techniques become available
True chance to be X disciplinary
A wise man once told me “That truly novel discoveries are more likely to occur where disciplines interact”
UAS + RS+ Ecology will provide the bestoutcomes.

Opportunities
An Opportunity to be influential – Affect on ground outcomes
Make the world a better place

Currently problemsBut There is also a strong need
A strong need creates great opportunities.Great opportunities sometimes need a little encouragement…
