SPLIT POLYGONS: Specify a relative part (in percent) or an absolute value (in map units) that you want to cut off an existing polygon. You may use this tool for the following purposes: - Split digitized roofs in the middle (50%) - Divide fields into exact parts (e.g. for soil samples) - Cut off an exact part of a field for cultivation planning BEZIER CURVES: Specify, if you want to create arrows or normal lines. The arrows are created as multipart polylines consisting of three single parts. If you want to create arrows, you have to specify an angle and a length (depends on your map units and scale) of the arrowhead. You can only use this tool to create polylines (not polygons). You may use this tool for the following purposes: - Visualization of traffic flows - Water, air or any other streaming - Digitizing any polylines with smooth edges THREE-CLICK SHAPES: Define rectangles or circles by three clicks. If the shape is a rectangle, you define one side with the first two clicks and then doubleclick on the opposite side. If you digitize circles, you place three points on the perimeter of the circle. You may use this tool for the following purposes: - Digitizing rectangle shapes, like roofs, buildings etc. - Digitizing circles from which you can't see the center (e.g. silos) CENTER LINES: Load a polygon theme with longish shapes into your view and activate the theme. With this feature you can draw a line from outside a shape into the shape. The creation of the centerline starts at that side of the polygon and continues (if successful) to the opposite side. If you activate "snap to center", the start point (and also the end point) of the center line is exactly positioned between two vertices of the shape. The absolue vertex density is the distance between the vertices of the centerline in map units (it may differ in specific cases, especially if the shape is very broad). If you specify a relative vertex density (which is recommended) of the value n, the absolute distance between the vertices of the centerline matches the ratio of the polygon width (if the small side of the polygon has two vertices) by n. The maximum curvature specifies the maximum angle in degrees between two vertices (also this may differ in special cases, especially at the conclusion of the centerline). If your computer is very fast, you can decrease the precision of deviation. Centerlines become more accurate with a lower precision. You may use this tool for the following purposes: - Find centerlines of rivers, streets |
| MOVE SHAPES: Specify a step in map units and a direction in degree, clockwise from the North which has a value of 0. Then press the button with the running man. You can also use the arrow buttons to move the shape(s) around. If there are any features selected, only the selected features are shifted. Use the top right button to undo the changes. SCALE SHAPES: Specify a factor to scale the shape(s) or selected features respectively. Values between 0 and 1 shrinks the shapes, values higher than 1 expand them. You can specify a reference point for scaling the shapes with the reference point tool (default is center of the selected shapes). The values can also be changed manually. Use the top right button to undo the changes. ROTATE SHAPES: Specify an angle to rotate the shape(s) or selected features respectively. The rotation angle is specified in degree, clockwise from the North which has a value of 0. You can specify a reference point for the rotation of the shapes with the reference point tool (default is center of the selected shapes). The values can also be changed manually. Use the top right button to undo the changes. |
