PROGRAM:
NAME
sortshp - sort a Shape data set
SYNOPSIS
sortshp [ infile outfile item [ascending | descending] | -v]
DESCRIPTION
sortshp sorts a Shape data set based on a single column in ascending or descending order.
Supports INTEGER, DOUBLE and STRING column types. Useful for prioritizing shapes for
rendering and/or labeling.
The idea here is that if you know that you need to display a certain attribute classed by
a certain value, it will be faster for MapServer to access that value if it is at the
beginning of the attribute file.
OPTIONS
infile The name of the .shp file
outfile
The name of the .shp/.shx and .dbf files to create
item Name of the field to sort on
ascending, descending
Sort order (default: ascending)
-v Display mapserver version and build options.
EXAMPLE
This example uses a roads file ('roads_ugl') that has a field with road classes in integer
format ('class1').
sortshp roads_ugl roads-sort class1 ascending
Result:
A new Shape data set named 'roads-sort.shp' is created with shapes sorted in
ascending order, according to the values in the 'class1' field.
