Example 3 (below) shows a small section of results from a user selection of ships carrying a cargo of coal. Each 20 mins longitude by 10 mins latitude cell is colour-coded according to the wreck numbers within that cell. A key is dynamically generated and reflects useful intervals based on the size of the data set. Clicking on the cell id loads the precise positions of wrecks within the cell, and provision is made for confidence factors associated with the wreck position. Mousing-over these positions highlights the wreck names; click then shows comprehensive information, in this case about the F. D. Lambert. |
