Introduction

Welcome to eoApp Australia, a free visualiser of EOMAP's water quality products covering Sunshine Coast in Queensland, and Ningaloo Reef and Barrow Island in West Australia.

Using its proprietary science, EOMAP is now generating these products in near real time for all Australian waters. We also have the capability to go back in time as far as 2001. If you are interested in purchasing or subscribing to any of these products, please visit our online store or contact us via info@eomap.com.

What this eoApp shows

Turbidity: a measure of the degree to which light is being backscattered by particles in the water and therefore strongly related to the concentration of suspended matter in the water column. Tracking changes in turbidity is useful when for example monitoring sediment plumes from dredging and dumping activities.

Visibility: a measure of the visibility in the water column, and therefore directly related to what a diver would experience if underwater at this particular location.

Reef Bathymetry: is the depth of the water column. It can also be thought of as an underwater digital elevation model of the seafloor. The bathymetry data layer displayed here is taken from EOMAP's world first bathymetry map product of the entire Great Barrier Reef at 30 m horizontal resolution (resampled to 500m).

How to use this eoApp

On the right hand side of the top bar, you will find the basic map tools for interacting with the map, such as panning, zooming, and placing a virtual measuring station.

In the blue panel on the right hand side, you can essentially do following things:

• Select which of the three parameters you wish to visualise: turbidity, visibility, or reef bathymetry.
• Select for which date or time period you wish to see your selected parameter. Currently you can see the parameter values for the last three days, or the average parameter values for the last three months.
• See the parameter value and geographic coordinates for your virtual measuring station.
• Generate a time series plot of the selected parameter value at your virtual measuring station.
• You can deactivate our by default applied shallow water mask in order to see measurements that are likely being influenced by the seafloor (when the seafloor is visible to the satellite sensor, an overestimation of the water quality parameter can occur)

FAQ

Q: Why is there no data for my location on any of the last three days?
A: Most likely your location was covered by clouds during the last three days. This is why we also provide the monthly averages.

Q: I am interested in a location outside the polygon areas that you feature here. How can I view water quality maps for my location?
A: Please send us an email indicating the area you are interested in. If we get enough requests for the same area, we could add it to this free visualiser. Otherwise, we are happy to give you a no obligations quote for how we could meet your specific needs.

Q: How can I learn more about these types of satellite-derived map and data water quality products?
A: You can start by downloading our related information booklet . Of course, this does not cover everything, but you will find links to additional reading in the booklet.

Q: We are an organisation that would like to subscribe to your data feed for turbidity and visibility over our own areas of interest. Can you provide us with our own eoApp for our project?
A: Absolutely. We would set you up with your own secure eoApp, covering your area(s) of interest and we can also modify some of the functionality to suit your needs.

Q: Can I get higher resolution data as well?
A: Yes, we also offer a 30m product and in some instances even a 2m product. Just send us an email with your requested area or visit our online store at www.eomap.com/store

About EOMAP

EOMAP is the leading commercial provider in satellite-derived information on aquatic systems, acting worldwide as an operational mapping service provider for the offshore industry and environmental agencies. Pioneering in the field of commercial, satellite-derived high resolution water quality and bathymetry, EOMAP solutions rely on standardized physical models which are independent of scale, sensor type, and geographic location. Key services include satellite derived bathymetry surveys, seafloor mapping and operational water quality monitoring. EOMAP value adding services can furthermore be applied at regional through to intercontinental scales, providing continuous and long term environmental information through integrating multiple satellite resources.

Disclaimer

Earth observation data are in general recorded under changing environmental conditions. EOMAP value adding software corrects for most relevant environmental conditions. However, with respect to the physical nature of the remote sensing method the achievable product quality can differ due to varying observation angles, varying atmospheric(-), surface(-) and in-water conditions or changing sensor raw data quality with each scene. Therefore, EOMAP cannot take any responsibility caused by the usage and interpretation of the remote sensing products. Of course, EOMAP will undertake all possible efforts to assure a constant product quality.
