Features & Functions
| Face | Feature | Description |
|---|---|---|
| (Default) | Identify | This function is available when no tool button is selected. If another button is selected, deselecting it enables "Identify." Click on the cell you want to get the information for. The popup window will come out, showing #observations in the cell. Be patient as it may take the results several seconds to show. |
  |
Species of interest |
Specify the name of you species of interest.
|
 |
Zoom in |
To zoom in, you need to define a rectangle on the map where you want to zoom in. First click on the map to locate one of the two diagonal vertices of the rectangle. Release the mouse button and move the mouse to the other diagonal point. The red guiding line appears. Then click again to fix the rectangle. |
 |
Draw region of interest |
A region of interest (ROI) takes a rectangular shape. First click on the map to locate one of the two diagonal vertices of the
rectangle. Release the mouse button and move the mouse to the
other diagonal point. The red guiding line appears. Then click again to fix the rectangle. The map is updated automatically, extracting observations in the ROI drawn. |
 |
Remove ROI |
To remove the region of interest (ROI), click the button and click on the ROI you want to remove. The map is updated automatically. |
    |
Observations by taxa |
Click one of the buttons to filter the observations on the map to that taxa group. OBIS-SEAMAP groups species into three taxa groups. [All] includes all the three groups. The numbers to the right of the buttons are the numbers of observations (not animals). All observations from ship/aerial surveys and data from tagged animals are counted. |

Grid size indicator |
The current grid size in degree. There are three resolutions for the grid-based distribution map: 1/0.1/0.01 degree. The grid size automatically changes according to the current zoom level. Zoom level: 0 - 4: 1 degree Zoom level: 5 - 8: 0.1 degree Zoom level: 9 - : 0.01 degree |
 |
Grid color legend |
Grids are color-coded by the number of observations in cells. the color schema changes according to the grid size (zoom level). It also changes when a species is chosen. |
