Drawing

drawing menu

The Drawing menu located on the bottom left side of the map provides tools which can be used to mark up the map with custom shapes, text and labels. Drawing objects can be placed at any location and can be drawn on top of aerial imagery in order to delineate certain geographical areas. These Drawing objects can be printed along with the map, but will disappear after the user logs out of the AbaData 2.0 session. In order to have the objects persist even after logging out, the map must be saved using the Save Map feature. Please see the Save Map section of this userguide for more information on saving maps.

 

Circle Tool

The Draw a Circle tool allows the user to draw a circle by clicking a centrepoint on the map and dragging the mouse to the desired radius.  Different style options are available and the radius of the circle can be displayed by clicking on the Label with Radius checkbox.

The previous image shows a circle drawn on top of an aerial image. The circle will match the Fill, Line and Thickness styles and colours selected prior to clicking on the map to draw it.

edit circle

Once a drawing object is created on the map, options are available to move, edit, rotate and scale or delete it. To access this menu, right click on the drawing object and select the item to perform the desired task. If the Vertices option is selected, points will appear along the boundary of the object allowing the user to change the shape of the object, as in the example below.

edit vertices

The Rotate/Scale option used on a circle would allow the user to turn a circle into an ellipse, the Move option allows the user to click on the object and drag it to another location, and the Delete option will remove the drawing object from the map.

Line Tool


line
The Draw Line feature lets the user put a multi-point line on the AbaData 2.0 map, with the line characteristics being set in the Draw a Line dialogue box that appears when you click on the Line heading under Drawing.

Draw a Line

Draw a Line

As with the Draw a Circle, the line can be edited, moved, deleted and rotated after it is drawn by right-clicking on the line and choosing the appropriate option in the menu that appears.  The length of the line segments can be labelled by checking the Label with Distance checkbox and the total length of the line will be displayed in the Draw a Line dialogue box once the line is drawn.

The Vertices option under the Draw Line menu allows the line to be bent and modified after the line has originally been drawn.

Profile Line

Profile Line

The profile Line option in the Drawing item menu is only available when right-clicking on a line drawn on AbaData 2.0, and will not work for other drawing object types. When selected, the Profile Line option will open up a new window showing a graph of the elevation in metres above sea level for the length of the line. This elevation is derived from the Digital Elevation Model. An example of an elevation profile is shown in the following image.

Square Tool


square
Drawing a square on AbaData 2.0 is similar to drawing a circle or line, in that clicking on the Square option under the Drawing tools menu opens up the Draw a Square dialogue box.

Draw a Square

Draw a Square

As shown in the previous image, squares (or rectangles) will always be drawn with sides vertical and the top and bottom horizontal to the map. As the square is drawn, the size of the X and Y axis will be displayed in metres in the Draw a Square box and the square can be labelled with the area. If the user wishes to have the square set at a skewed angle, right click on the square and select the Rotate/Scale option on the menu that appears.

The image above left shows the square after being rotated and scaled to fit the clearing shown on the aerial image. Further changes can be made to the shape of the square by selecting the Vertices option and moving some points as was done to the image above right. If there will be many changes made to the shape of a square, it may be more efficient to use the Polygon drawing tool, as described in the following section.

 

Polygon Tool

The Polygon drawing tool lets the user draw polygons of varying shapes and styles on the map. If it the easiest way of creating a drawing object with a completely unique shape.

Draw a Polygon

Draw a Polygon

To draw a polygon based on the Fill, Line and Thickness settings in the Draw a Polygon dialog box, click on the map at the turning points of the desired polygon shape. As the cursor is moved to a new location, a shaded area will be shown between the starting point of the polygon and the current cursor location as shown in the previous image. The shaded area represents the shape of the polygon if the user was to double-click and join the points.

Completed Polygon

Once the polygon has been drawn on the map, the polygon edit menu can be opened by right-clicking on the polygon.

 

Text Tool


text
The Text tool under the Drawing menu allows text to be inserted at any location on the map. By accessing the Create Text dialogue box, the user can set the font, size, styles and angle of the text. Clicking on the map will then centre the text on that point. Right clicking text that has been created with bring up the edit menu where the text can be moved or deleted and some aspects of the text can be altered. In the text editing dialogue, the Rotate/Scale option will not be available, because the size and orientation of the text will be changed through the Edit/Styles selection.

Create Text

Create Text

The size of the text on the map is a font size, so it will not scale down or up with the map. It will stay a constant size so if text is added and the scale of the map changes significantly, the text may need to be edited in size to be in proportion with the new map view.

 

buffer delete all

By clicking on the Delete All button in the Drawing menu, you can delete all text and objects created by the Drawing tools.
