GeosOp

geosop is a CLI (command-line interface) for GEOS. It can be used to:

Run GEOS operations on one or many geometries
Output geometry resuls in various formats (WKT and WKB)
Convert between WKT and WKB
Time the performance of operations
Check for memory leaks in operations
Check the semantics of GEOS operations

For more information see the README.

Usage

The geosop executable is in bin.

Print usage instructions
```
bin/geosop

Print usage instructions and list of available operations
```
bin/geosop --help
```
Read a file of geometries in WKT and output them as WKB
```
bin/geosop -a geoms.wkt -f wkb
```
Compute the area of geometries in a WKT file and output them as text
```
bin/geosop -a geoms.wkt --format=txt area
```
Compute the centroids of geometries in a WKT file and output them as WKT
```
bin/geosop -a geoms.wkt -f wkt centroid
```

JTS TestBuilder

The JTS TestBuilder can be useful for creating, visualizing and processing GEOS geometry. Because GEOS and JTS are so closely related it can also be used as a way of verifying GEOS behaviour. For more information see the JTS doc.
