Create Chart Group
The second step in chart data production is creating a chart group, which is a key process in creating electronic navigational charts from scratch. When creating a group, it is necessary to create or set detailed chart information such as the feature identifier sequence, map range, version number, purpose, scale, vertical datum, and depth datum. The wizard-based creation process in SuperMap iDesktopX helps you quickly complete the creation of a chart group. After creation, you can also perform type conversion on editable groups to meet more requirements.
