  Automatic label placement - Wikipedia, the free encyclopedia
The issue of automatic label placement is one of the most difficult problems in GIS (Geographic Information System), but other kinds of computer-generated graphics - like charts, graphs etc. - require good placement of labels.
When the temperature is high, simulated annealing performs almost random changes to the label placement, being able to escape a local optimum.
On uniformly and densely labelled maps, usually the single set will contain the majority of labels, and on maps for which the labelling is not uniform it may bring very big performance benefits.

The map label placement problem is discussed in the second section, followed by a section on the use of simulated annealing to solve general combinatorial optimization problems.
Christensen, et al, compared the various label placement algorithms implemented in their program on randomly generated maps with respect to complexity of implementation, computational time, and quality of results measured by the number of labels deleted from the map.
Label placement programs using simulated annealing are easy to implement, with the hardest programming work involved in detecting potential label-label and label-symbol overplots.

 Automatic Label Placement
The label's purpose is served best when it is both readable and also near its element, where readability most importantly results from the label being placed so that it does not overlap with other graph elements.
Internal labeling, in contrast, is directly provided by certain major layout algorithms as an integrated part of the layout calculation.
In the context of automatic label placement, all valid positions are at the same time "candidates" among which a labeling algorithm can choose the best match to ultimately place the label.

 Automatic label placement   (Site not responding. Last check: 2007-10-15)
The simplest greedy algorithm places consecutive labels on themap in positions that result in minimal extra overlap of labels.
Slightly more complex algorithms rely on local optimization to reach a local optimum of a placement evaluation function - ineach iteration placement of a single label is moved to another position, and if it improves the result, the move is preserved.
On uniformly and densely labelled maps, usually thesingle set will contain the majority of labels, and on maps for which the labelling is not uniform it may bring very bigperformance benefits.

The labels for a mountain are stepping up, with the top edges of text facing the peak, and the labels for a basin or crater are stepping down, with the bottom edges of text facing the bottom of the depression.
That is, the labels for a mountain are to be placed below an east-west line through the peak and those for a crater are to be placed above an east-west line through the crater bottom.

The issue of automatic label placement is one of the most difficult problems in Geographic information system, but other kinds of computer-generated graphics - like charts, graphs etc. - require good placement of labels.
They are often quite complex, and they usually perform worse than simulated annealing.
Other algorithms are also used, like various graph solutions, integer programming etc. One simple optimization that's important on real maps is dividing a set of labels into smaller sets that can be solved independently.

 Chapter 5. Automatic Graph Layout
Label placement algorithms leave both a graph's nodes and its edge paths unaltered, but compute suitable positions for labels.
Their criteria for the arrangement are such that the labels do not overlap with each other or any of the graph elements.
Bus-like edge paths can be generated for edges connecting to a common node, and both starting point and end point of an edge path can be constrained to a specific side of a node or even explicit coordinates.

 A General Cartographic Labeling Algorithm - Edmondson, Christensen, Marks, Shieber (ResearchIndex)
Abstract: Some apparently powerful algorithms for automatic label placement on maps use heuristics that capture considerable cartographic expertise but are hampered by provably inefficient methods of search and optimization.
On the other hand, no approach to label placement that is based on an efficient optimization technique has been applied to the production of general cartographic maps --- those with labeled point, line, and area features --- and shown to generate labelings of acceptable quality.
Each labeling is scored according to principles derived from Monomier [9] Tufte [12] 13] and Edmundson [5] Unlike Edmundson, who uses...
