Editing Tools Overview

Before editing features, the layer you want to edit should be set editable, and the various editing tools can be used. Editing features can be divided into two parts: editing existing features and creating features.

Editing Existing Features: the feature that you want to edit should be selected by Select Feature function first. After the feature is selected, choose a needed function from the various editing tools, such as moving, offsetting or deleting feature or vertex.

Creating Features: creating features function adds new features of point, line and polygon on the map. Moreover, the attributes and geography can be edited as well.

The editing is functioned by using the various tools to work the corresponding functions. For example, when a feature is to be edited, Selec Feature tool should be selected and used to do the selection. Consequently, editing tools should be selected and used to edit the feature or vertex (line or polygon layer). As a result, before you start to edit, select a tool first. Following, we are giving you an overview on editing tools.

Select Feature tool menu: through this tool menu, the feature you want to edit can be selected or you can cancel the selection; to PDA equipped with GPS function, features at the GPS position can be selected or the map can be zoomed to the selected feature's extent for better viewing.

	Select Feature	Select a feature to edit.
	Select at GPS Position	Select a feature at GPS position.
	Clear Edit Selection	Clear the edit selection.
	Zoom to Selected Feature	Zoom the selected feature to the map center.
	Move to Selected Feature	Move the selected feature to the map center.
	Repeated Attribute	Repeat the attributes of the last created feature.

Vertex Edit tool menu: through these editing tools, moving, inserting and deleting vertex can be done. Besides, continuing to sketch vertices of a line can be done with the tool menu.

Icon	Name	Description
	Vertex Edit	Edit the feature's vertices.
	Move Vertex	Move the vertex.
	Insert Vertex	Insert a new vertex into the feature.
	Segment Polyline	Continue to digital new vertices behind the last vertex.

Point tool menu: you can create different types of features, such as point, line and polygon.

(1) Point: Create a point feature.

(2) Line: Create line features by line, polyline and freehand line functions.

(3) Polygon: Create polygon features by rectangle, polygon, ellipse, circle and freehand polygon functions.

Icon	Name	Description
	Point	Create a point feature (for point layer).
	Line	Create a line, a line feature (for line layer).
	Polyline	Create a polyline, a polyline feature (for line layer).
	Freehand Line	Create a freehand line, a line feature (for line layer).
	Polygon	Create a polygon, a polygon feature (for polygon layer).
	Rectangle	Draw a rectangle to create a polygon feature (for polygon layer).
	Circle	Draw a circle to create a polygon feature (for polygon layer).
	Ellipse	Draw an ellipse to create a polygon feature (for polygon layer).
	Freehand Polygon	Draw a freehand polygon to create a polygon feature (for polygon layer).

Feature Properties tool menu: You can edit feature properties and move, rotate, offset, scale, resize and delete the features.

Icon	Name	Description
	Feature Properties	Edit or modify attribute data.
	Move Feature	Move the feature.
	Rotate Feature	Rotate the feature.
	Offset Feature	Offset the feature.
	Scale Feature	Scale feature with the feature center as the standard.
	Resize Feature	Resize the width or height of feature.
	Delete Feature	Delete the feature.

Text Point tool menu: it provides the tools to edit the features for the graphics layer.

Icon	Name	Description
	Text Point	Add a text point for a graphics layer.
	Text Polyline	Add a text polyline for a graphics layer.
	Text Polygon	Add a text polygon for a graphics layer.
	Text Rectangle	Add a text rectangle for a graphics layer.
	Text Ellipse	Add a text ellipse for a graphics layer.

Capture Point Using GPS tool menu: when GPS is activated, features can be created at the GPS position.

	Capture Point Using GPS	Add a point feature at GPS position.
	Add GPS Vertex	Add a new vertex using GPS.
	Add GPS Vertices Continuously	Add vertices continuously using GPS.

NOTE: some tools are usable only under some specific conditions. For example, the GPS related tools can be usable only if GPS is activated. A usable tool presents in full colors; on the contrary, an unusable tool presents in gray color.
