Detailed Description

Read occurrences data of one or more group from a TeTable in a TeDataBase.

Table is read and stored as a linked list of objects from the Occurrences class.

Allow navigation through the object list.

Format:

The table must have 4 columns.

• Columns 1 : Group name (string).
• Column 2 : longitude (-180.0 <= lat <= 180.0).
• Column 3 : latitude: (-90.0 <= long <= 90.0).
• Column 4 : Group identifier (string).
