AUTONAP is not a true rule-based system because the rules are implicit in the RATFOR program rather than ex- isting in an independent knowledge base.  ...  Pfefferkorn et al. (1985) report a cartographic expert system, ACES, for labeling maps that is similar in objective and approach to AUTONAP.  ... 

Automation and the Map Label Placement Problem: A Comparison of Two GIS Implementations of Label Placement

Jill Phelps Kern, Cynthia A. Brewer
2008 Cartographic Perspectives  
Label Placement Rules Freeman and Ahn (1987) revisited Imhof's rules for placing labels on maps with an eye to automating map annotation from a rule-based, expert system perspective.  ...  Freeman and Ahn expanded upon and modified Imhof's rules, creating a system of name placement rules applicable to automated labeling of point, line, and area features, while recognizing that an automated  ...  "Freeman and Ahn compiled rules for label placement and developed a rule-based "expert" automatic name placement system . . ." cartographic perspectives developed sufficiently, the Census Bureau instead  ...

Towards an evaluation of quality for names placement methods

Steven Van Dijk, Marc Van Kreveld, Tycho Strijk, Alexander Wolff
2002 International Journal of Geographical Information Science  
This paper gives a classification of most label placement rules, and formalizes them into a function that can serve as a quality measure for label placement.  ...  There are many rules and customs that describe aspects of good label placement, like readability and clear association.  ...  Automated label placement requires that the standard guidelines for label placement be formalized. The simplest of all rules to follow is that names shouldn't overlap.  ...

Optimizing map labeling of point features based on an onion peeling approach

Wan D Bae, Shayma Alkobaisi, Sada Narayanappa, Petr Vojtechovsky, Kye Y. Bae
2011 Journal of Spatial Information Science  
Map labeling of point-features is the problem of placing text labels to corresponding point-features on a map in a way that minimizes overlaps while satisfying basic rules for the quality.  ...  This problem is a critical problem in the applications of cartography and Geographical Information Systems (GIS).  ...  The authors of [10] developed a rule-based system using Prolog to place names on different types of maps such as road maps and county maps.  ...

Computational Cartography (Dagstuhl Seminar 99381)

Martien Molenaar, Marc van Kreveld, Frank Wagner, Rob Weibel
2000
The ønal step is then classifying the areas and for this a rule-based system has been used.  ...  The integrated system has a client-server architecture. The server is implemented in C++ (Descartes) and Prolog (Kepler), the client in Java. The system is available for Windows and Unix platforms.  ...  This talk proposed a quality measure for the result of the second phase, allowing the comparison of label placement programs.  ...
