Class JTSOpCmd

java.lang.Object
org.locationtech.jtstest.cmd.JTSOpCmd
public class JTSOpCmd extends Object
A CLI to run JTS TestBuilder operations. Allows easier execution of JTS functions on test data for debugging purposes.

Examples: 

--- Compute the area of a WKT geometry, output it
jtsop -a some-file-with-geom.wkt area 

--- Validate geometries from a WKT file using limit and offset
jtsop -a some-file-with-geom.wkt -limit 100 -offset 40 isValid 

--- Compute the unary union of a WKT geometry, output as WKB
jtsop -a some-file-with-geom.wkt -f wkb Overlay.unaryUnion 

--- Compute the union of two geometries in WKT and WKB, output as WKT
jtsop -a some-file-with-geom.wkt -b some-other-geom.wkb Overlay.Union

--- Compute the buffer of distance 10 of a WKT geometry, output as GeoJSON
jtsop -a some-file-with-geom.wkt -f geojson Buffer.buffer 10

--- Compute the buffer of a literal geometry, output as WKT
jtsop -a "POINT (10 10)" Buffer.buffer 10

--- Compute buffers of multiple sizes
jtsop -a "POINT (10 10)" Buffer.buffer 1,10,100

--- Run op for each A 
jtsop -a "MULTIPOINT ((10 10), (20 20))" -eacha Buffer.buffer

--- Output a literal geometry as GeoJSON
jtsop -a "POINT (10 10)" -f geojson

--- Run op but don't output result (quiet mode) 
jtsop -a "MULTIPOINT ((10 10), (20 20))" -q Buffer.buffer
