Abstract
A method of mapping an inter-tidal area, comprising: obtaining, over a period of time, image data comprising: a sequence of images of the inter-tidal area at a range of different stages of the tide, and the time at which each image was obtained; determining an elevation of a location in the image, by correlating the changes in an image value over time at the location with tidal data comprising the elevation of the tide over the period of time.
Claims25
A method of mapping an inter-tidal area, comprising:
- obtaining, over a period of time, image data comprising:
- a sequence of images of the inter-tidal area at a range of different stages of the tide, and the time at which each image was obtained;
- determining an elevation of a location in each image, by correlating the changes in an image value over time at the location with tidal data comprising the elevation of the tide over the period of time, wherein the tidal data comprises the transitions, over the period of time, between wet and dry at each of a plurality of elevations.
(canceled)
An apparatus for mapping an inter-tidal area, comprising:
- a computer, configured to process a sequence of images of the inter-tidal area, obtained over a period of time at a range of different stages of the tide and a time at which each image was obtained, recorded on a data storage device so as to:
- create a measure of change with respect to time for an image location,
- determine an elevation for the location, based on a similarity between the measure of change at the location and the transitions from wet to dry at each elevation recorded in tidal data, wherein the tidal data comprises transitions with respect to time between wet and dry at each elevation.
(canceled)
A computer readable medium comprising software for mapping an inter-tidal area that, when loaded on a suitable computer, configures the computer to process a sequence of images of the inter-tidal area, obtained over a period of time at a range of different stages of the tide and a time at which each image was obtained, recorded on a data storage device so as to:
- create a measure of change with respect to time for an image location, and
- determine an elevation for the location, based on a similarity between the measure of change at each location and the transitions from wet to dry at each elevation recorded in tidal data, wherein the tidal data comprises transitions with respect to time between wet and dry at each elevation.
