Abstract
A display to display a visual representation of geographic information in a first portion of a display and text information in tabular format in a second portion of a display. The text information is subdivided into a group table and a member list table. The group table lists named groups in tabular form and members of the groups are listed in the member list table. Tabular information may include attachments which are capable of appearing as overlaid graphical representations on the geographic display. A method of coordinating the display of geographic graphical and tabular information provides hide/show capabilities for attachment graphics responsive to selection of tabular information. A method for modelling and storing geographic data is disclosed providing the steps of dividing the spatial extent defined by geographic data into uniquely identified cells, grouping geographic data by cells, and storing grouped geographic data into a long binary field of a database record in a relational database.
