By Clodoveu A.D. Jr. Davis, Antonio M.V.M. Monteiro

The GeoInfo sequence of clinical meetings is an annual discussion board for exploring learn, improvement and leading edge functions in geographic details technology and comparable parts. This booklet presents a privileged view of what's presently taking place within the box of geoinformatics, and a preview of what may be the warmer advancements and learn subject matters many years from now. also, it comprises fresh examine effects on spatial databases, spatial ontologies, computational geometry and visualization for geographic details platforms, geostatistics and spatial facts, spatial research, interoperability, and cutting edge functions of geotechnologies.

Sample text

C. G. -T. Wu trates the initial state of the array crossings and the indices begin and end. The numbers stored in the fields of crossings corresponds to the indices j of the segments vivj that the upward ray intersects. Observe that the number of crossings can be directly obtained by the subtraction (end-begin). (a) (b) Fig. 15. The data structure used in our strategy (a) in pseudocode and (b) its graphical representation for the polyline of Figure 14(a). The procedure computeCrossings outlined in Code 1 performs the computation of the crossings between the ray and the original subpolyline, stores them in the array and initializes the indices.

Figure 9(c) illustrates an example of consistent simplification (a) (b) (c) Fig. 9. Our strategy to handle linear features: (a, b) separate application of the sidedness criterion to each subpolyline; (c) an example of consistent simplification. We consider that the interior of the polygons (represented by the shaded regions in Figure 9) are determined with the parity (or odd-even) rule. We compute the number of crossings between a ray from the feature and the polygon formed by a subpolyline and its correspondent simplifying line segment.

For elucidating how the linear feature consistency works, we introduce the parity property as follows. Two points are considered to be on the same side of a polygon, if a line connecting them crosses the polygon an even number of times. Otherwise, they are considered to be on opposite sides. Figures 10(c) and 10(d) illustrate two examples of the parity property. Notice that the crossings on self-intersecting points of a polyline are counted as many as the number of segments that intersect on it.
