Data Input/Output
Openjump natively support these vector files:
- SHP – ESRI Shapefile (Wikipedia and ESRI Shapefile spacification)
- GML – Geographic Markup Language file, ver. 2
- JML - JUMP Geographic Markup Language file, a modification of GML file format which doesn’t require an extra input/output template
- WKT – Well-Known-Text file, which uses simple text to define geometrical shapes
- FME - GML files created by SAFE’s Feature Manipulation Engine tools for data transformation and translation.
To load a file, choose Load dataset(s)... function in File menu.
To open GML files OpenJUMP requires input template file (see VIVID SOLUTION – Jump Workbench User’s Guide – par. 12.1 Writing Input Template, page 48)
WKT files generally do not have attribute. They can be used to draw geometries in the Layer View or to store usefull geometries that can be used in other project (e.g. Drawing point symbols to use with Cadplan vertex plugin (see also Drawing point symbols).
To save a dataset to a new file choose “Save dataset as…” in the File menu.
Remenber that SHP can have only one geometry (point, line or polygon), while JML, GML and FML can have all the geometry.
If you want to convert a JML, GML or FML file to a Shapefile, remember to copy the three geometries features in three different layers (Using Edit>select items by geometry type and choosing point/Linestring/Polygon) and saìve them separatelly
OpenJUMP can open other types of file using external plugins. See Import Export File wiki page
