hale»studio 4.0: Ready for the Future - and for XPlanung!
01.07.2020 by Thorsten Reitz, Christopher Hönn

Our main objective for this release has been to modernize hale studio from the ground up, by making it compliant with current OpenJDK versions, using the most recent eclipse RCP version, and by upgrading as many dependencies such as GeoTools as feasible. While we did not yet achieve full compliance with Java 11, we think that the current builds have accumulated so many updates that it is worth giving it to you as a new major release:

  • Major updates to the documentation and help
  • Reader and Writer for GeoPackage
  • A specific Writer for XPlanGML that supports partitioning by plan
  • Added presets for CEN/TS 17268 (TN-ITS), ISO 19139, XPlanGML 4.0/4.1/5.0/5.1/5.2/5.3beta and GeoInfoDok 6.0.1/7.0/7.1
  • Enhancements for GML Dictionary Codelist handling
  • Support for TLS 1.2
  • Various bug fixes and enhancements

The complete changelog is available here. To avoid any compatibility issues when using an existing workspace, we recommend starting with a fresh one when you install hale»studio 4.0. Furthermore, due to the GeoTools & JTS upgrade, the geometry bindings have changed. This breaks backwards compatibility of Groovy Scripts and Alignments created in 4.0. We will provide information on how you can manually backport your Groovy scripts if necessary.

If you are a user of the hale studio pro plugins, you need to upgrade these as well. Please reach out to the Servicedesk to get the new plug-ins.

If you would like to get some hale»studio training, check out our current webinar schedule.

Reader and Writer for GeoPackage

GeoPackage is the optimal, open format for delivering medium to large sized data sets to GIS users. It is a single file that can store tables, vector geometries and rasters. It is extensible and can deal with simple and more detailed data models well. There is even the option to add views and to store styles in a GeoPackage. It doesn’t have issues such as 11 character attribute limits, unknown encodings, missing or incomplete projection files, and is very fast to access.

For these reasons, there have been several requests to add GeoPackage to the list of supported formats for hale studio. We have now added a Reader and a Writer. The Writer can create GeoPackages from scratch, including the schema and metadata. This means you can even use an XML schema and then write your data to a GeoPackage. However, the required model transformations to make this work in complex cases are planned for the next release.

This work was funded by the Umweltbundesamt Austria and Rijkswaterstaat Netherlands, and supported by the European Environmental Agency.

XPlanGML writer and presets

XPlanung is a standard for all kinds of spatial plans that is currently implemented by thousands of agencies all across Germany. To make the work with XPlanGML in hale studio easier, we have added two features - Schema Presets for all releveant XPlanGML versions, and a writer that creates XPlanAuszug files without requiring manual configuration. This writer furthermore supports writing the data to one file per plan object - so you will get a file that has, for example the BP_Plan, the BP_Bereich and all directly or indirectly referenced objects.

This work was supported by the XLeitstelle.

After last week’s focus on Groovy, today we will take a closer look on other advanced functions and functionalities of hale studio that often get overlooked but provide great value. Making good use of these functionalities can help you on your way to becoming a more efficient hale studio power user.

For the remainder of this article it’s assumed that you have working knowledge of hale studio and are familiar with its terminology. For a primer on hale studio concepts, please refer to the online help.

Synchronize Schema Explorer and Alignment View

In large and complex source and/or target schemas, it can become difficult to find a specific source type or attribute. If you have the type or attribute relation open in the Alignment view, the button “Synchronise with cell selection” (highlighted in the screenshot below) can simplify navigation. When active, hale studio will jump to the source and target types or attributes of the selected mapping in the Schema Explorer.

Spatial Join

An advanced feature of hale studio is its ability to join objects of your source dataset based on the spatial relationship of their geometries with the Spatial Join transformation function. In contrast, the regular Join is limited to the equality of textual attributes. For the comparison of geometries, Spatial Join supports all modes of the Dimensionally Extended nine-Intersection Model: contains, covered by, covers, crosses, equals, intersects, overlaps, touches, and within.

Internally, Spatial Join is powered by a spatial index that is built when hale studio imports the source data. You can leverage the spatial index in your own Groovy scripts via the helper functions _.geom.spatialIndexQuery and _.geom.boundaryCovers. Make sure to check out our previous post on the subject if you would like to learn more about using the spatial index in Groovy scripts!

Filtering Data with Contexts

In hale studio, a context on a schema element can be used to restrict the element to certain instances or property values. After setting a context on a schema element, the effect of mapping cells defined on that element is limited to the instances or property values that match the context condition.

A special type of context is the index context that can be used in cases where the order of elements in the source instance conveys a special meaning. In the example below, the information on the language of a name is given implicitly through the order in which the names appear. The first name is in German, the second name is in English, and the third one is in Italian.

More information about contexts is available in the hale studio help. There you can also find a tutorial on how to create contexts.

Make the Most of the Map View

The Map view of hale studio provides you with a cartographic representation of both source and transformed data. Both can be displayed alongside each other, with different layouts to choose from. An often overlooked feature of the Map view is that you can select geometries by clicking on them and then inspect the properties of the corresponding object in the data view. You can also select multiple instances, just hold the Ctrl key when you click. Selected instances are highlighted in red, as can be seen in the screenshot below.

You can find the data views for source and transformed instances directly beneath the map. To show the properties of the objects selected in the map, activate the Use instances selected in the application mode in the upper left corner of the data view.

Vice versa you can also filter the data view and highlight the geometries of the filtered instances in the map. To do that, first activate the Random/filtered source data instances mode in the data view (upper left corner), then enter the desired filter expression and finally activate the globe button in the upper right corner of the data view. In the screenshot below, the source objects were filtered for a specific value of the bodenart property. The geometries of the filtered objects are highlighted in red in the map.
