In the past ILWIS had limited 3D capabilities. One could make a GeoRef3D which generated a 3D image (with a DTM) but it was cumbersome to use and quite slow. One of the goals of the 3.8 was upgrading these capabilities to something usefull.

As people may have noticed who looked at the beta-1 of ILWIS 3.8, the way the user interacts with the layers displayed in the Map window is significantly different from previous versions. Basically the windows menu has been deprecated in favor of the layer view on the left side of the window. Almost all actions that changed the content of the rendering area are done through the layer view.
Being at the FOSS4G conference in Denver, I just hold a presentation about our Thin SWE Client for the OGC Sensor Observation Service. The functionality of the client is focused on the display of time series data. This comprises a diagram view with comfortable navigation mechanisms (e.g. an overview time series, panning, zooming, etc.). In addition a table view showing all measured values belonging to a selected time series, as well as a map overview for displaying the sensor locations are included. This display functionality is complemented by further features like an export function (CSV, XLS and PDF export) and comfortable menus that help users to select the data they are interested in.
Besides giving the presentation (please find it below), I demonstrated the software successfully 🙂 If you are keen to see the application in action yourself, please visit our demo deployment.
My first few blogs will be about the upcomming 3.8 of which I published a first beta just before my holidays. The next beta will follow shortly.
The last few years, as a programmer, I encountered serious limitations in what ILWIS could render on the screen. The rendering system was designed when computers had far less memomry, puny (compared to now) graphic processors and the data-sets were much smaller. With large, multi-spectral and spatial – temporal data-sets, with big feature sets, web technology etc.., the existing system ran into serious limitations.
