Self-Adjusting Legends for Proportional Symbol Maps
Proportional symbol maps are frequently used to represent numerical data. Commonly used symbols are squares or circles that are area-proportional to the numerical values. Proportional-symbol mapping is included in most geographic information systems (GIS) and is frequently used in digital atlases or Web mapping engines. Graduated symbols are simple for the map author to generate and easy for th...
متن کاملOptimizing the Layout of Proportional Symbol Maps
Proportional symbol maps are a cartographic tool to assist in the visualization and analysis of quantitative data associated with specific locations (earthquake magnitudes, oil well production, temperature at weather stations, etc.). Symbol sizes are proportional to the magnitude of the quantities that they represent. We present a novel integer programming model to draw opaque disks on a map wi...
متن کاملOptimizing the Layout of Proportional Symbol Maps: Polyhedra and Computation
P symbol maps are a cartographic tool to assist in the visualization and analysis of quantitative data associated with specific locations, such as earthquake magnitudes, oil well production, and temperature at weather stations. As the name suggests, symbol sizes are proportional to the magnitude of the physical quantities that they represent. We present two novel integer linear programming (ILP...
متن کاملSignal-to-symbol Mapping for Laser Rangefinders
A new approach for computing qualitative part-based descriptions of 3D objects is presented. The object descriptions are obtained in two steps: Object segmenta-tion into parts and part model identiication. Beginning with single-or multi-view range data of a 3D object, we simulate the charge density distribution over an object's surface which has been tessellated by a triangular mesh. We detect ...
متن کاملSymbol mapping diversity design for packet retransmissions through fading channels
In this work we present a simple, but effective method of enhancing and exploiting diversity from multiple packet transmissions in systems that employ nonbinary linear modulations such as PSK and QAM. This diversity improvement results from redesigning the symbol mapping for each packet transmission. Using a general framework for evaluating the upper bound of bit error rate (BER) with multiple ...
