Automated Name Placement with High Cartographic Quality: City Street Maps
Introduction Mapping agencies are gradually abandoning manual production techniques and increasingly producing traditional paper maps from digital geographic databases, using mapmaking software and automated cartography. However, computer-aided...
A Visual Basic Algorithm for the Winkel Tripel Projection
Introduction Over the years, the National Geographic Society (NGS) has made several changes in their choice of map projection for their world reference maps. From 1922 until 1988, world maps were produced using the Van der Grinten I projection (Figure...
Equal Area Map Projection for Irregularly Shaped Objects
Introduction During the last three decades, scientists have begun imaging and studying many previously unknown planetary bodies in our solar system. Many of those planetary bodies have been determined as having irregular shapes. With the increasing...
Institutionalization of Geographic Information Technologies: Unifying Concept?
Introduction Geographic information technologies--such as geographic information systems (GIS)--have developed dramatically since the early pioneering work of Roger Tomlinson and others in the 1960s. (An overview of the state-of-the-art in the early...
Medial Axis Generalization of River Networks
Introduction Maps are rich in geometric structure. Adjacencies between features, containment in regions, intersections of lines or regions, and relative orientations or proximities of features all contribute to the value of maps and map operations....
Modeling Dynamic Polygon Objects in Space and Time: A New Graph-Based Technique
Introduction The element of time plays a critical role in the analysis of dynamic spatial systems. For example, plant ecologists who study processes controlling landscape heterogeneity through patch dynamics, investigate how size, shape, location,...
Reducing Linear and Perimeter Measurement Errors in Raster-Based Data
Introduction A fundamental issue in cartography and geographic information systems (GIS) is determining the appropriate resolution (or cell size) to represent geographic features when using a raster data structure. Most commonly, vector-based polygons...
Spatial Accuracy Assessment of Wetland Permit Data
Introduction An important aspect of coastal management in the United States continues to be wetland management. Despite federal, state, and local legislation designed to limit the alteration of wetland habitat, wetland loss continues because of...
Visual and Statistical Comparisons of Surface Modeling Techniques for Point-Based Environmental Data
Introduction Points, together with lines, areas, and surfaces, represent most of the tangible natural and human phenomena that we encounter on an everyday basis. Information recorded by points with specific geographical coordinates represents an...
