AspEdit manual Border segments
PurposeIn aeronautical publications, airspace boundaries are often defined as follows:
AspEdit allows to define the "along xxx border" segments in a coded form, as follows:
Upon export to OpenAir, all the points on the border segments will be inserted.
Not only borders can be inserted this way, but also other airspace areas.
Inserting a border segment
Modifying a border segmentIn the list of the Area dialog box, double-click on any line belonging to the border segment, the Border dialog box will open for the selected segment
Clockwise or counterclockwise?In most geographical software, shapes are turning clockwise as standard. This means that when viewed from the center, the points of the shape are sequenced clockwise. If both the source shape and the shape from which to insert a segment are clockwise, "clockwise" should be selected in the Border dialog box.
However, if any shape is counterclockwise, select counterclockwise in the Border dialog box.
In any case, check the results on the map display. If the result is not as expected, invert the selection.
Difference between the border function and the shapes function
Borders can be countries or other airspace areas, also airways or areas consisting of circle, border or shape segments.
