Every non-military federal geospatial product of the United States is tied to the NSRS so that they may all overlap and align accurately. GeoDist: Constrained distance calculation and associated geotools. Within the United States, this accurate determination of positions forms the scientific basis for all geodetic control, known collectively as the National Spatial Reference System (NSRS). The costs and benefits of compliance with international Anti-Money Laundering (AML) and financial transparency rules, together with the difference in Money Laundering (ML)-related risk-perception across countries as well as the effects dirty money flows may have on the behavior of global financial flows, have been investigated by various scholars (Christensen and Hampton.
GEODIST PLOT CODE
The following code demonstrates the relative speed advantages of the different distance measures implemented in the geodist package.

If predecessors, a list whose ith element is a list of vectors, the jth of which contains the intervening vertices on all. A matrix containing the geodesic distances between each pair of vertices. (Note that geodist does not accept sf-format objects the sf package itself should be used for that.) Note that The mapbox cheap ruler algorithm is intended to provide approximate yet very fast distance calculations within small areas (typically the size of single cities or study sites). If count.pathsTRUE, a matrix containing the number of geodesics between each pair of vertices. Distance measures currently implemented are Haversine, Vincenty (spherical), the very fast mapbox cheap ruler (see their blog post), and the “reference” implementation of Karney (2013), as implemented in the package sf. I am trying to use the geodist function in the gmt package along with ddply in the plyr package to calculate the distance between two sets of coordinates by a grouping variable (Tow) but am getting. n 10 10Īll outputs are distances in metres, calculated with a variety of spherical and elliptical distance measures. x and predicted are the values for the x- and y-axis. The plot on the right shows the overall fit (orange line the grand mean with no random effects influencing the prediction), the predictions accounting just for random effects at the level of individual females (blue dots), and the raw data.
GEODIST PLOT SERIES
The returned data frames always have the same, consistent structure and column names, so it’s easy to create ggplot-plots without the need to re-write the function call. The plot on the left above shows predictions for various series of experimental trials, and the raw data.

Input(s) to the geodist() function can be in arbitrary rectangular format. S3 method for class btergmgof: plot(x, boxplot TRUE, boxplot.mfrow TRUE, boxplot.dsp TRUE, boxplot.esp TRUE, boxplot.geodist TRUE, gree. There is a generic plot()-method to plot the results using ggplot2.
