Vector Read capabilities

OpenJUMP natively support these vector files:

To load a file, choose Open Files... function in File menu.

To open GML files OpenJUMP requires input template file (see VIVID SOLUTIONs – Jump Workbench User's Guide – par. 12.1 Writing Input Template, page 48).

WKT files generally do not have attributes. 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).

Read compressed vector files

Openjump can read shp, jml or wkt formats embeded in a zip file.

[OpenJUMP 1.6] OpenJUMP also supports bzip2 and gzip compressed files e.g. data.shp.gz.

Write capabilities

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, GeoJSON and FML can have all the geometry.

If you want to convert a JML, GML, GeoJSON 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
