- removed layers from the pixel info when the layer is removed from the layer tree,
- dates are now correctly read in the date form.
ILWIS 3.8 represents a major upgrade from ILWIS 3.7. Changes and improvements have mainly focussed on visualization, however, additional issues have been addressed.
Changes in ILWIS 3.8
- Display options form has been replaced by an extended and improved Layer tree on the left side of the map window.
- Pixel info has a permanent location on the lower left side of the map window.
- The map window has a command line which works the same as the main window’s command line. Maps calculated in this command line are automatically added to the map window.
- Map window menus have been substantially reduced. Much of their functionality has been moved to the Layer tree.
- LatLon maps can show their coordinates as decimal coordinates. This toggle can be found in the Options/Metric Coordinates menu.
- Visualizations can be shown full screen without any UI elements. This toggle can be found in the Options/Full Screen menu.
- Automatic reprojection and resampling is available. The map window can display maps of different geometries (both raster and vector) and will automatically morph the maps to a target geometry. The geometry of the map can be changed on-the-fly.
- Annotation is available in the map window for legends (per layer), boundaries and scale bar.
- The tree node "Display Tools" has a context menu that controls the visibility of tools.
- Base maps have been added to the system folder. This (small) set of maps can be used as background/context layers. Each base map acts as a system object.
- Map backgrounds and surroundings can be changed with respect to color and transparency.
- The distance measurer can be used on paths (multiple line segments) with the help of the the ctrl button.
- The previous layer tree has been massively extended. It now replaces part of the main menu. "Tools" that control a coherent subset of visualization properties are available at all levels of the tree. They can be global or have effect on only one layer.
- Raster maps
- Enhanced performance
- Interactive representation value creation
- Polygon maps
- Enhanced performace. The first time a polygon map is shown it generates a support file (triangulation) which it uses subsequently.
- Boundaries and Areas are separate entities with separate properties.
- Segment maps
- Enhanced performance. All vector maps now use a spatial indexing scheme to quickly retrieve the relation between a coordinate and its features. This speeds up the retrieval of segment values at a particular location.
- Point maps
- Symbolization has been completely changed. There is now one consistent system that uses small "svg-like" text files to define the symbolization.
- Object collections
- An object collection of maps of the same type and domain can function as a single layer. As a result, all maps are stretched in the same way.
- Map lists
- Dedicated tools for map lists. Apart from animations, a set of dedicated tools has been implemented specifically for map lists.
- Cross section. A graph can be displayed for a point location. It shows all the values of the map list for that point. Multiple points can be defined with the help of the ctrl button.
- Hovmoeller diagram. A pattern detection representation of lines drawn on a map can be combined with a map list to produce a Hovmoeller diagram.
- Track profile. This displays a profile graph of a path on the map. A multi-segment path can be created with the help of the ctrl button. Multiple maps can be added to the profile graph to demonstrate relationships between the profiles of these maps.
- Transparency. This can be added at many levels and mostly on-the-fly. Transparency follows a 0 (no transparency) to 100 (fully transparent) scale. It can be applied to the following objects/properties:
- Layers: raster, polygon, segment, point
- Areas and/or boundaries of polygons
- Lines of grid
- Extrusions (3D)
- partial transparent interactive representation ???
- Selections of polygon maps based on class
- Selections of raster maps based on numerical value
- Interactive value stretching. Dymamically adapts stretch values based on a set of sliders (min,max).
- Attribute tool. The display attribute (column) can be changed on the fly.
- Layer applications. All applications relevant for a certain layer type can be started from the Layer tree. Any maps produced here are immediately added to the map window.
- Point editor and segment editor. These tools have been rewritten and are now part of the Layer tree.
- All layers can be shown in 3D via a simple toggle.
- Z coordinates can be any numerical value source; e.g. raster maps, attribute columns.
- Rotation can be carried out by pressing the ctrl button and the left mouse button simultaneously, zooming via ctrl button and the mouse wheel, and panning with the ctrl button and the right mouse button.
- All 3D properties are controlled by the 3D properties tool which is activated by the context menu of the display options node.
- 3D grid creation is possible.
- 3D properties. Controls Z-data source, scaling and offsets and the use of extrusions (and properties).
Animations (formerly slide show)
- Animations can be made from map lists (raster) or object collections (vector).
- Animations function as a normal layer in the map window. Tools applicable for single layers, work for animations.
- Animations work in 3D
- Multiple Animations can run in one or more map windows (however, there may be performance issues).
- Animations may use index information or real time information. Real time information is derived from a time column in a map list's attribute table.
- Several animations may be synschronized according to index information or real time.
- Animations can be saved as .avi files.
- Highlight tool. Singles out a selection on the map to highlight during animation
- Threshold tool. Changes display colors of pixels above and/or below a certain threshold based on an attribute table. This tool can be accessed from the animation management form.
- MapListCondense: Condenses a map list into a smaller map list, i.e. aggregates maps into one map according to a step size and specific aggregation rules.
- MapListExpand: Expands the map list and creates intermediate maps based on certain interpolation rules, i.e. the reverse of MapListCondense.
- MapListChangeDetection: Makes use of a number of simple change detection schemes to determine changes in map lists.
- MapAggregateMaplist: Aggregates a map list in a single map based on certain aggregation rules.
- TableAttributeFromMapList: Creates an attribute table for a map list based on aggregated numbers from maps in a map list
- ColumnAttributeFromMapList: Creates an attribute column for a map list based on aggregated numbers from maps in an existing map list table
- TableCreateTimeColumn: Creates a time column in a table. The time column is derived from a map list based on a (user-defined) pattern in the name of the map list.
- Map list and Object collection can have an attribute table. Each record matches the corresponding index in the list/collection.
- The Operation list has been extended to include a "finder" which filters the list.
- A Spanish UI translation has been included.
- The help system has been decompiled and now uses html files instead of the bundled (chm) format.
- The domain "time" has been included. This handles date/time information based on an ISO standard.
- ILWIS now has a server component that can run as an (ILWIS-specific) application server. A WPS server has been implemented.
ILWIS 3.8 beta 2
This is the second beta version of ILWIS 3.8. There is no proper installer, just copy the ilwis folder from the zip to the desired location. The main focus of this version has been visualization and the bulk of the changes can be found there. There are, however, additional significant changes.The list below contains the bulk of them.
Changes for Ilwis 3.8 beta-2 with respect to beta-1
- new tools
- Hovmoller diagram
- change coordinate system
- color composite tool
- map info tool
- point editor (probably still needs some work)
- segment editor (probably still needs some work)
- full screen mode (menu : Options->Full Screen)
- base maps (add layer form and context menu in catalog). This only works with maps that have proper coordinate systems (so no CoordSystem unknown).
- optional decimal Lat/Lon on info bar.
- copy clipboard
- String translation system has been reworked to make it easier to translate ILWIS to other languages. ILWIS 3.8 will contain a spanish translation of the UI (almost finished).
Not yet finished
- sample set editor
- Stereo and Anaglyph
- UI Clean up. This is partially done. There are still a number of items in the menu that do not work properly anymore, because their functionality has be subsumed in the layer view.
ILWIS 3.8 beta
This is the first beta release. There is no proper installer, just copy the ilwis folder from the zip to the desired location. The focus of this version is visualization.
Changes for Ilwis 3.8 beta-1
- No display options form anymore. Functionality has been subsumed in the Layer view
- Leading spatial reference system for the view is the first layer added to the view. Rastermap georeferencing is now irrelevant. Everything is reprojected/resampled on the fly. Display of multiple raster maps with different georeferencing is possible as long as the coordinate systems are convertible.
- Improved performance: OpenGL is the main graphics library
- Greatly improved support for animations. Animations are now a normal layer in a mapwindow. All tools applicable to that type of layer should be applicable to the animations.
- All views can also be displayed in 3D.
- Almost all elements can be made transparent.
- Increased interactive behaviour
- Layer (tree) view has been substantially changed and extended.
- The layer now contains a node called Display tools which contains all the "tools" (listed below) used in rendering a view.
- The Display tools node has a right mouse button menu with which you can add/remove tools from the tools branch
- Display tools is a general term used for all distinct modules that can manipulate a subset of properties of a view. For example there is a display tool that manages the transparency of items. Tools appear as separate nodes in the display tool branch. Some tools are "umbrella tools", they only function as organizational nodes as they have a number of other tools as children. Please note that on many nodes you may double click to open a form with properties of the tool.
- Transparency tool: transparency of feature, layers, line etc..
- Grid tool: draws grid lines at fixed distances
- Gratticule tool: draws gratticule lines of the lat/lon system
- 3D tool (global): switches the perspective to 3D
- Attribute table tool: attribute data source for features/pixels
- Color tool: contains fixed color tool and representation tool
- fixed color tool: single color or multiple colors for class/id domains
- representation tool: setting of the current representation
- Legend tool: shows the distribution of values in the range for the specific domain (class/ value). Class items may be switched on/off individually.
- Boundary tool: switches the boundaries on/off in polygon layers
- Area tool: switches the filled areas on/off in polygon layers
- Stretch tool: interactive stretching for value maps
- 3D Properties tool: Umbrella tool for some 3D tools
- Data Source tool: any numeric source can be used for the z-values in a map. This is traditionally a dtm, but ILWIS accepts any source.
- Scaling: the z - exaggeration and z - offset in z images
- Extrusion: a downward extension of a feature to make its location on the ground level clearer
- Interactive Representation tool: interactively makes value representations (can also be used for interactive slicing)
- Annotations: Umbrella tool for the annotation tools. Currently only one child tool present, others will follow.
- Annotation Legend: "On Map" legend
- 3D Stack (global): In 3D view it will layer the layers with fixed distances.
- 3D Cursor: In 3D view it will draw a line from the selected location to the ground level, intersecting with all layers.
- Line Style tool: properties of lines
- Point Symbolization tool: Symbolization of points
- Point Scaling tool: point size scaling with attributes
- Track Profile tool: profile of a drawn track on the map. Can have multiple legs and multiple sources. For both value and class domains
- Cross Section tool: all the values of one or more map lists on one or more locations in a graph
- Distance Measures tool: the length of a line of one or more legs on the map
- Run tool (animation layer only): speed and synchronization of animations
- Time Selection (animation only): Which frames will be included in the animation
- Area of Interest Selection (animation only)
- Feature Tracking tool (animation only): tracks features over time in a object collection
- Layer info table (old pixel info) available in the view.
- Point symbols are svg-like (tiny subset) xml files that can be added, changed etc. (located in resources\symbols)
- Change detection
- Aggregate map list
- Create time column (not a true application)
Help files: now available as true HTML in the browser and can be located in the installation folder of ILWIS.
Operation List: (not tree) in the main window now has a finder edit box.
Domain Time: ILWIS now supports Time as a domain (Date + Time) as defined by ISO 8601.
Command Zip: makes a zip file of an ILWIS file plus all the support files it needs.
