This module demonstrates how GeoAPI services can be used from a complex software like LibreOffice or OpenOffice.org. This add-in adds the following formulas to the Calc software, which can be used in spreadsheets for performing coordinate operations:
| OOo Formulas | Programmatic names | Parameters | Supported by this demo |
|---|---|---|---|
| CRS.DESCRIPTION | org.opengis.openoffice.XReferencing.getDescription | EPSG code | incomplete |
| CRS.SCOPE | org.opengis.openoffice.XReferencing.getScope | EPSG code | no |
| CRS.VALID.AREA | org.opengis.openoffice.XReferencing.getValidArea | EPSG code | no |
| CRS.BOUNDING.BOX | org.opengis.openoffice.XReferencing.getBoundingBox | EPSG code | no |
| CRS.REMARKS | org.opengis.openoffice.XReferencing.getRemarks | EPSG code | no |
| CRS.AXIS | org.opengis.openoffice.XReferencing.getAxis | EPSG code, dimension | incomplete |
| CRS.PARAMETER | org.opengis.openoffice.XReferencing.getParameter | EPSG code, parameter name | no |
| CRS.WKT | org.opengis.openoffice.XReferencing.getWKT | EPSG code, authority name | no |
| TRANSFORM.WKT | org.opengis.openoffice.XReferencing.getTransformWKT | EPSG code, authority name | no |
| TRANSFORM.ACCURACY | org.opengis.openoffice.XReferencing.getAccuracy | source CRS, target CRS | no |
| TRANSFORM.COORD | org.opengis.openoffice.XReferencing.getTransformedCoordinates | coordinates, source CRS, target CRS | yes |
This demo uses the Proj.4 binding, which requires a native library. However implementors are free to distribute this add-in with the geoapi-proj4.jar file replaced by their own implementation. See here for instructions.
Users should be able to switch implementations as long as the various add-ins use the same programmatic names than the one listed in the above table, with the same parameters.
