Description

Hi,

while mapping from high-res areal images in Dortmund/Germany? I used the rectangle drawing tool in merkaartor for the first time. In my experience this tool did not help very much. I wanted to map buildings, most of them simple rectangles in arbitrary orientation. Using the merkaartor rectangle tool this involves a sequence of dragging to create the rectangle, selecting it, using the "Rotate" tool to orient and to resize it. At this point I usually noticed that I had guessed the aspect ratio wrong and was struck. Resizing of rectangles keeps the aspect ratio fixed. Back to square one.

This could be easily improved using "three point rectangle drawing" as follows: Click on one corner of the object to start the rectangle. Merkaartor draws a line following the mouse pointer. Click to mark the second corner of the rectangle. The first line of the rectangle is fixed, we have width and orientation now. Move the mouse. The selection turns into a rectangle. A third mouse click fixes the height. This sequence works much quicker and follows the use patterns from basic way drawing.

Best regards

Thomas

Are you aware that, while drawing a rectangle or polygon, pressing <SHIFT> allows you to rotate on the fly?

The anchor is the first point, which is then also the first corner. The second click would create the opposite corner.

Did you try? Is it good enough in your opinion?
