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)
  • other
    • 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.

Available tools

  • 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)
  • PolygonMapListTracking

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.

ILWIS 3.7.2

This release contains a number of important bug fixes for ILWIS 3.7.1:

  • fixed import shape files bug
  • fixed a number of related point map bugs which caused a shift of one record in the point table:
    • Table to PointMap
    • some statistical methods using pointmaps
  • improved the legend of the mapwindow for value maps
  • corrected parsing of the sinusoidal projection
  • corrected incorrect deletion of members of a maplist
  • created a new application to solve some of the issues with MapListStatistics called MapListAggregate
  • created a more robust way of opening polygon files with corrupt polygons
  • solved some issues when importing raster maplists

ILWIS 3.7.1

New applications include:

  • PolygonMapSliverRemoval: removes small polygons with an area below a certain threshold (percentage wise or absolute number)
  • PointMapCross: combines a pointmap with a maplist by adding the values of the maps in the list at a point's coordinate as columns to the pointmap's attribute table
  • French translation of the ILWIS user interface (not including help files): available through the preference form (use extension .fr)
  • Bug fixes


New vector operations include:


other changes:

  • The data format for polygon files has been changed and is not compatible with ILWIS 3.6. ILWIS 3.7 will read the ILWIS 3.0 data format for polygon files but only save to the new format.
  • The ILWIS 2.0 data format for vectors is no longer supported.
  • Some operations that disappeared in 3.6 are back in 3.7 (e.g. some matrix operations).
  • WMS locations in the navigator remain after closing the application.
  • Customization of the operations menu/tree is (limited) possible.
  • About form has been significantly changed.
  • A number of bugs have been solved.

ILWIS 3.6.1


  • Inherited spatial reference systems from top layers in a WMS now handled correctly
  • WMS Catalog(Ilwis object) works properly


  • Output pathing for the imported file fixed
  • Shape file import works properly
  • Dxf file import works properly


  • GeoTif export rewritten. It is less rigid in what it exports and stays truer to its original content
  • SEBS Operations menu corrected

Batch Command line processing

  • ILWIS as a client should not interfere anymore with running batch command scripts (multi threading problemn is fixed)


New features are:

  • Inclusion of GDAL in much the same way as Geogateway once was included. Non ILWIS raster data can be used natively in ILWIS. This is a big improvement with respect to the previous support of GDAL.
  • Postgres tables and Postgis point and segment maps can be accessed natively from a Postgis database. A first implementation has ben made to access these sources of data.
  • User interface for Import has been improved to support a plug-in model for imports.
  • Imports now largely follow a plug-in model (some old ones excepted). New imports can be added without changing ILWIS.
  • The plug-in model has been extended to cover plug-in,s stored in zip files, that need their own folder structure to organize their functionality.
  • Surface Energy Balancing (SEBS) has been extended and improved.
  • Improved installation program
  • Bug fixes

ILWIS 3.5.2

The following functions and parameters now work properly:

  • the interactive color composite,
  • the parameters %r, %k, and some other '%' parameters,
  • the MapIter parameters.

ILWIS 3.5.1

The following bugs were fixed:

  • the expression errors is now properly communicated,
  • the MapIterProp has been reintroduced (was ommitted during the original conversion of the applications to a plugin model),
  • the SimpleCalc has been reintroduced (was ommitted during the original conversion of the applications to a plugin model),
  • the History works properly again.

ILWIS 3.5 extends the functionality offered by ILWIS Open 3.4. New user features include:

  • ILWIS as an OGC compliant WMS client. It can now process GetCapabilities requests and make the WMS layers (or combinations of them) available as raster maps in ILWIS (domain color). These can be combined with any local data.
  • Surface energy balances with preprocssing functionality (SEBS). ILWIS is now able to produce Surface Energy Balance maps and carry out the chain of preprocssing to create the products needed for processing.

New developer features include:

  • ILWIS is now a MS Visual 2008 project.
  • ILWIS applications and applications user interface now form a plug-in system. One can extend ILWIS applications without changing anything to ILWIS.
  • ILWIS user interface and ILWIS analytical functionality have now been completely seperated making it easier to write server side applications for ILWIS.
