Intertidal ecosystems have primarily been studied using field-based sampling; remote sensing offers the ability to collect data over large areas in a snapshot of time that could complement field-based sampling methods by extrapolating them into the wider spatial and temporal context.

Conventional remote sensing tools (such as satellite and aircraft imaging) provide data at limited spatial and temporal resolutions and relatively high costs for small-scale environmental science and ecologically-focussed studies. In this paper, we describe a low-cost, kite-based imaging system and photogrammetric/mapping procedure that was developed for constructing high-resolution, three-dimensional, multi-spectral terrain models of intertidal rocky shores. The processing procedure uses automatic image feature detection and matching, structure-from-motion and photo-textured terrain surface reconstruction algorithms that require minimal human input and only a small number of ground control points and allow the use of cheap, consumer-grade digital cameras. The resulting maps combine imagery at visible and near-infrared wavelengths and topographic information at sub-centimeter resolutions over an intertidal shoreline 200 m long, thus enabling spatial properties of the intertidal environment to be determined across a hierarchy of spatial scales.

Results of the system are presented for an intertidal rocky shore at Jervis Bay, New South Wales, Australia. Potential uses of this technique include mapping of plant (micro- and macro-algae) and animal (e.g. gastropods) assemblages at multiple spatial and temporal scales.

hosty have you ever thought of having a thread called This is nothing to do with archaeology by "something to do with hangers-on?"

Wonderful Unit of 1 ;o)
You have hit the nail on the head with that comment and will be supported by those who languish in Ludittism and ignorance (would I be the devil's advocate?!).
To dig a site, you have to discover/locate it first......if you are not just following the builders!
With imaging think:
Location
Delineation
Assimilation
Manipulation
Interpretation
Presentation
In terms of working outside the visible spectrum, if you are a palaeographer you do not throw a visually faded, or blank, manuscript or papyrus away. You examine it under UV and infra-red light.
Currently, pre-excavated sites, and sites undergoing excavation, are often poorly photographed even in the visible spectrum.

Photography, 3D imaging/photogrammetry and personal aerial imaging techniques should be taught to all archaeology undergraduates, so that this area, and other areas of the archaeological sciences, are not deemed foreign and something for 'hangers on'. Grab and hold on to the techniques applicable to your profession.
Every archaeologist should have the technical expertise to produce an aerial image of a site within 10 minutes of arrival. We have primary school children who can do it!

Unit believes all archaeology is done by the jcb.... if has not touched the hallowed blade of his ditching bucket then it cannot possibly be archaeology- I am - and seem to be in good company - a person who believes archaeology can expand beyond the tiny blinkered boundaries of the negative eval bucket scoop that is Units world. ( well it does include pensions, which he seems to think has something to do with archaeology - but then, why let being hoisted on his own petard stop him )

Archaeology images and aerial shots. I also use them to create trench shots, I use them to do wider landscape analysis I use them to give me elevated images for buildings archaeology and I use them for a host of other reasons. I also think that environmental is an acceptable topic for archaeology as is osteology. architecture and even ... god forbid historical analysis...

I honestly want to apologise. I just cannot believe that I wrote this just a few days ago. Its the type of thing that I thought I stopped doing about a year ago. Sorry sorry sorry. Now where was I oh yes problem finding a site. its a right buggar.
