geographic distance matrix generator

The Geographic Distance Matrix Generator is a very lightweight and simple to use application. The Geographic Distance Matrix Generator is a platform-independent Java application that implements the same powerful suite of spherical functions as the Perpendicular Distance Calculator to compute all pair wise distances from a simple list of geographic coordinates. For the U.S. counties, the geographic layer is provided in latitude-longitude decimal degrees (i.e., the coordinates are unprojected). function distancevector is applied to a matrix and a vector to compute the pair wise distances between each row of the matrix and the vector. For weighted strategies (inverse distance or zone of indifference), neighboring features have a varying amount of impact (or influence), and weights are computed to reflect that variation. http://biodiversityinformatics.amnh.org/open_source/gdmg/, The Perpendicular Distance Calculator is a platform-independent Java application that implements a powerful suite of spherical functions for processing observations made during standard line transect surveys. Pairwise distance heat maps are used to compare atomic distances within molecules, between points in space or between geographic locations on a map.

Principal Coordinates Analysis — Torgerson method part 1. With the increasing availability of mobile GPS technology, every scientist can obtain latitude-longitude coordinates for target organisms, which can later be used in regression analyses in conjunction with genetic distances, or matrix associations with permutations for statistical testing, as well as multiple matrix correlations when testing for more complex biogeographic and ecological scenarios (Mantel and partial Mantel tests, respectively).The Geographic Distance Matrix Generator can be used to easily generate distance matrices needed for these types of analyses. A Google Maps interface has been embedded in a simulation tool developed in the C# programming language. We calculated geographic distance for each pair of populations based on their latitude and longitude data using Geographic Distance Matrix Generator 1.2.3 . distance to the road network. Consequently, the use of a straight line Euclidean distance is inappropriate (at least, for larger distances). mantel.test(dists1, dists2, perms=10000, method='pearson', tail='upper') This will measure the veridical Pearson correlation between the two sets of pairwise distances. With this option you define feature relationships in terms of both a space (fixed distance) and a time (fixed-time interval) window. a service that provides travel distance and time for a matrix of origins and destinations. http://biodiversityinformatics.amnh.org/open_source/pdc/.
