Recent Releases of SpatialPosition

SpatialPosition - CRAN Version

Major changes:

  • sf and sp objects are allowed as input and output (use returnclass = "sf" for sf output).
  • functions use sf for spatial computation.
  • rasterToContourPoly() (based on rgeos & sp) is deprecated in favor of isopoly() (based on isoband and sf).
  • bug fix in smoothy for some computations with NAs.
  • addition of a dataset hospital, with hospital points and capacity and Paris polygon.
  • suppression of the QGIS vignette, irrelevant in regard to QGIS v3, and not really specific to SpatialPosition

SpatialPosition - CRAN Version

Major changes:

  • Introduce mcStewart to compute stewart potentiels using parallel processing
  • Introduce smoothy to compute distance weighted mean.
  • Introduce a vignette on how to SpatialPosition with QGIS. ## Minor changes:
  • (Re)introduce a longlat param in stewart, mcStewart, huff and reilly to select between eucliean and great circles distances.
  • Add a bypassctrl param in stewart, huff and reilly to allow computations on large datasets
  • More points in the default mask of raster poly
  • Rewrite of CreateGrid and rasterToContourPoly functions

SpatialPosition - CRAN Version

Minor changes:

  • Check mask size and validity in ratserToContourPoly
  • Better SpatialPolygonsDataFrame output in rasterToContourPoly
  • Default distance computation is in meters using the Great Circle distance (WGS84 ellipsoid) method.

SpatialPosition - CRAN Version

Major changes:

  • Introduce the quickStewart function that outputs stewart contour polygons easily. Ratio of potentials are allowed.
  • Introduce rasterToContourPoly to replace contourStewart.
  • contourStewart is now deprecated. Use rasterToContour from raster to output contour lines and rasterToContourPoly from SpatialPosition to output polygons.

Minor changes:

  • A resolution is set by default in CreateGrid.
  • Vignettes are updated to reflect major changes.
