The editing of the chart feature object shall be based on the editable S-57 Chart Dataset Group. After an editable S-57 Chart is Dataset GroupAdd to Map, the editable state of the corresponding Chart Layer is automatically enabled, and the object can be edited at this time. Each feature object can only be edited in the corresponding Dataset. Therefore, when drawing a feature object, it is necessary to ensure that the Dataset corresponding to the object has been created in Chart Group. Dataset Type is divided into three types: point, line and plane.

After the editable state of Chart Layer is enabled, the editing operation of Chart Layer is basically the same as that of Normal Layer. You can perform object drawing and editing operations, such as Add, Delete Object, Edit, Add Node, Copy and Paste Object, and Edit Attribute. As well as some advanced editing operations, such as rotation, intersection, merging, etc. However, due to the special structure of Chart Layer, its editing is different from that of Normal Layer. This chapter will introduce the specific operation of Chart Feature Object Editing in detail.

Executive summary:

This section describes the operations related to adding feature objects in the feature object Dataset.

Describes how to filter the object you want to select from multiple selected object objects.

Describes the 14 Object Editing functions provided by the Chart Edit module.

This paper introduces the Attributes of the object and the related operations of editing the attributes of the object.
