Eonfusion version 2.1 is now complete and upgrades are being distributed. Existing Eonfusion license-holders will be contacted by our Support team with upgrade details during the coming weeks.
The new features in version 2.1 provide enhanced performance and stability, along with some very important extensions of Eonfusion's core functionalities. Here's a summary of the new additions:
In version 2.1 we provide two installation options for Eonfusion: 64-bit and 32-bit. The 64 bit version will run only on 64-bit operating systems and provide the crucial advantage of being able to access more than 2GB of RAM. Up to 128GB RAM is accessible by the Eonfusion process, which will have a significant performance benefit when working with large memory-intensive data sets.
A Media view that is linked to a Value probe now respects two-way linkage so that the media view not only responds to the probe, but the probe also responds to the slider of the media view. There are two key advantages:
- You can browse the media and keep a visual check on the probe location.
- You can more precisely position the probe by adjusting the media view's slider.
This is a new feature that allows you to create a media view that is synchronized with the leading edge of the scene slider. This is useful in two scenarios:
- Scenes where the media isn't attached to a moving object and therefore doesn't have an associated spatial trajectory. This is the case for fixed station cameras.
- Scenes where there are multiple sources of media that you wish to view as a synchronized set. For example, multiple video feeds from multiple cameras (either fixed or moving) in different locations.
The values gadget consists of a floating table in the scene (similar to a legend) that presents feature attribute values and interpolated vertex attribute values for 1D line features. The "position" along the line is derived from the leading edge of the slider. The key application is for fixed-location data: if a data set contains a number of time-varying attributes at a fixed location then the values gadget can be used to monitor the variation of the attribute values with time.
A much wider range of projections are now supported. The projection set that existed in V2.0 has been expanded and also now offers four ways of specifying a projection. In the "Select Projection" dialog box, there are now the following options:
- "Select using Type and Datum", which presents the type and datum lists in the same way as V2.0.
- "Enter ESPG code (European Petroleum Survey Group)"
- "Enter PROJ.4 string (PROJ.4 Cartographic Projection library)"
- "Enter WKT string (Well Known Text spatial reference)"
Each of the new options presents a field in which to specify a name for the projection and a field in which to enter the defining code or string.
The following data sources will now read and apply projection metadata if it is present in the input: Raster, Raster Folder, Raster Time Series, Shapefile, OGR, ODBC, ODBC (SQL). The Shapefile writer and KML raster writer will now write projection metadata to their outputs.
Rule sets for colour and radius can be exported and imported in version 2.1. This provides a useful shortcut for implementing common rule sets across multiple visualizers, as well as a means of archiving rule sets for future use.
There are now two ways of displaying scene contents in the Scene view. The traditional scene contents pane remains while a new "List" pane has been added. The old scene contents pane is now labeled the "Structure" pane. The List pane summarizes the scene contents pane by showing a list of visualizers along with any direct attachments such as legends or probes. This means that individual visualizers are much easier to find and toggle.
All operators now have a "Notes" tab. The purpose of the tab is to capture any relevant information that the dataflow author wishes to bind to the operator, whether for "note-to-self" purposes or for dataflow documentation. The text entry area of the notes tab supports rich text and the editor includes some basic rich text controls.
The Fuse Vector Sets and Intersect Vector Sets operators now have an additional option to "Fuse across dimensions". This creates additional links from features to corresponding features in higher dimensions. The primary use of this addition to the fusion operators is to enable transfer of feature attributes from 2D surface features down onto 1D line features and 0D point features.
Shared selection allows you to synchronize feature selections across tables and scenes. Features can be selected in either a scene view or in a table view and the selection will appear in any other scene and table views that are open. Table views also now contain an option to show either all of the table's rows or to only show the rows that correspond to selected items. This allows you to use the scene to select items and "build" a table view that lists only the selected items.
The Kernel Density add-in operator is being upgraded to certified standard. The operator performs a Kernel Density Estimation (KDE) operation on an input vertex set in either two or three dimensions. The output is a 2D or 3D raster populated with density and (optionally) corresponding quantile values.
The new "Transform Raster" operator provides a set of transform options for raster data. There are three options for specifying the transformation:
- Set scale, offset and rotation for each axis.
- Set minimum and maximum values for each coordinate.
- Enter an affine transformation for each axis.
In version 2.1 a raster with irregular spacing on axes other than X and Y can be seamlessly read into Eonfusion from netCDF and VRT formats. In previous versions, rasters with irregular spacing were deconstructed into separate bands.
