    • distance based spatial weights for points and polygons
  • Visualization and Queries
    • graphs, maps and table
    • linking and brushing of all maps and graphs, multiway linking of table
    • spatial selection on maps
    • query selection in table
  • Mapping
    • quantile and standard deviational maps
    • outlier maps: box map and percentile map
    • rate mapping and smoothing: excess risk map, Empirical Bayes smoothing, spatial smoothing
    • map movie

    Converting a single shapefile into several (Split by attribute)

    8 Feb

    Hello again!

    Just a quick note to tell you that today I found a very useful tool set to split a layer or shapefile in many shapefiles based in an attribute from the table.

    This is a very quick way to separate a layer of roads, counties and so on. It was created by the USGS and have also another 3 additional tools.

    I hope is as useful for you as it was for me πŸ™‚
