SIS 9 service release extends support for Ordnance Survey data formats

SIS 9 supported OS Open Zoomstack data in its pre-release format from the outset. In this latest service release, support for OS data released from January 2019 onwards has been brought up to date. SIS users can open data in OGC GeoPackage and select cartography from the four standard OS styles – ‘Light’, ‘Outdoor’, ‘Road’ and ‘Night’, and the defined ‘Grayscale’. OS Open Zoomstack opened from Mapbox MBTiles is also automatically styled. 

 The software’s OS Open Data Loader allows OS Open Zoomstack in OGC GeoPackage to be loaded into SQL Server, PostGIS and Oracle for corporate, network access to the data. OS Open Zoomstack data stored in these databases can be opened within SIS Desktop and styled by its ‘Add Overlay’ wizard. 

Continuing apace with other recent OS data updates, support is provided for OS Open Greenspace, OS Terrain 50 Contours, and OS VectorMap District in OGC GeoPackage format.  

As with all OS products, SIS loads the data directly into the software from the supplied files and structures and styles the data so it is ready for immediate use and cartographic output.  

To improve the performance of mapping services, the style padding property can be applied to an overlay rather than an SWD. This optimises resource use for drawing against individual layers as required, rather than applying padding to all layers in an SWD. 

Using the underlying mapping engine, GeognoSIS®, users of SIS WebMap can also make use of the updated OS format support. In addition, PDF output from SIS WebMap automatically includes a dynamic scale bar.
