Description
When labeling polygons, labels are often placed in unexpected locations including on the edge or even completely outside the polygon. I will attach two images to demonstrate. The first shows Flodida and bordering states, and the FL label falls on the FL/AL border. AL is not labeled at all even though there would be room for a label if the FL label was better placed. In this case the label POSITION was set to CC. The second image shows Alaska and northwest Canada. The label POSITION in this case is AUTO and it results in the BC label falling completely outside its polygon. None of the labels are really where I would want or expect them to be. From a cartographic viewpoint this is a serious problem. Chosing a different POSITION may help in this case, but in other areas of the map it would create new problems. What is really needed is a an assurance that labels will at least fall completely within the polygon they are associated with.
