CLC2012 Support Package history


CLC2012 Support Package is a significantly modified and improved version of the CLC2000 and CLC2006 Support Packages. The CLC2012 software has been developed for Remote Sensing Centre of Hungarian Institute of Geodesy, Cartography and Remote Sensing (FÖMI), consortium member of European Topic Centre Spatial Information and Analysis (ETC–SIA) in order to help implemen­tation of the European CLC2012 project managed by the European Environment Agency (EEA) within the framework of GMES Initial Operations (GIO).

CLC2012 Support Package is a set of standalone applications developed with Embarcadero Delphi XE2 and TatukGIS Developer Kernel. Thus user does not need to purchase, install and tune any other software to carry out CLC2012 change mapping.

Commonly a GIS software is designed primarily for viewing GIS databases with tools for creating maps, menus for handling databases and graphical editing tools. If software has editing possibilities too, these are general tools, not specialized for individual tasks. On the contrary, CLC2012 Support Package is a specialized, task oriented software tool, that significantly facilitates updating, change detection and mapping, quality control and correction of CORINE land cover databases by means of computer-assisted visual photo­interpretation. Consequently, this software is not applicable for creating, viewing or editing GIS databases in general. For theese purposes one can use any common commercial (e.g. ESRI ArcGIS) or free (e.g. Quantum GIS) software.

CLC2012 Support Package was downloadable from Eionet Forum homepage.

Countries 2012


Professional integrated software development environment for creating applications for arbitrary purposes. Delphi was originally developed by Borland Software Corporation as a rapid application development tool for Windows, based on the Object Pascal programming language. Since 2008 Embarcadero Technologies owns Borland's developer tools section.
Last versions generate native code for 32-bit and 64-bit Windows operating systems, as well as for 32-bit Mac OS X, iOS and Android operating system.

CLC2012 software preliminary considerations


Limits of the ArcView software

CLC2006 Support Package runs on the base of the ESRI ArcView software. Last version of ArcView (3.3) was released in May 2002 and since April 2005 ESRI has provided only limited support for this product. There is no guarantee that software runs under future Windows operating system versions without any problem. Institutions established lately or new users usually do not have licenses of this software. Additionally, in ArcView there is no possibility to use on-the-fly coordinate reference system transformations, and web mapping services. Due to these arguments it is reasonable to find a new basis for the further development of the CLC Support Package.

Financial considerations

The CLC2000 software was free for participating countries on the condition that it is used solely in the implementation of the CLC2000 project. Conversely, CLC2006 software was a commercial product, customers therefore could use software licenses without any time or project limitations. In case of CLC2012 Support Package the decision was to make it available for participating countries free of charge and at the same time make sure that no additional costs (of purchasing the background commercial GIS) put burden on participants. Therefore two options for development were left: either using open source software as background for the development, or creating standalone executable software with a royalty free GIS object library.

Creating standalone executable

Royalty free means that if the developer purchases the object library, all software products, created with help of this library, can be retailed or sold without any further payment to the manufacturer of the object library. The standalone executable can be developed in any common programming language (Delphi, C++Builder, .NET, etc.), that can handle Windows Visual Component Library (VCL) objects.

  • Developer does not need to conform to the unalterable facilities and restrictions of the background software.
  • The user interface and program features can be optimized for the work, without unnecessary tools and controls.
  • User does not need to purchase, install and tune any other software.

CLC2006 Support Package


CLC2006 Support Package was a significantly modified and improved version of CLC2000 Support Package. Beyond many improvements an advanced code, polygon area and code change probability statistics was available in the software. A fully new part of the package was the LUCAS photo viewer, which is a standalone executable written in Delphi programing language. The package consist of four main parts: InterPrepare for the national central team can be used for the preparation of source files and work directories for change detection. InterChange program provides a tool for the revision of CLC2000 land cover database and supports the interpretation of land cover changes in order to create the CLC2006 database. InterCheck program serves the checking of revised CLC2000 and CLC-Change map sheets. LUCAS photo viewer displays the main land cover and land use data of the currently selected LUCAS point as well as the field photographs belonging to the point, if any.

CLC2006 software was distributed by MLOG Instruments Ltd., Budapest, Hungary. In the European CLC2006 project 17 European national teams used this software (see figure). Further two countries purchased licenses only of the InterCheck program, the control part of the package. InterCheck program has been prepared primarily for supporting the CLC2006 Technical Team, although national central teams might also use it as a tool for final checking of the completed CLC2006 and CLC-Change databases.

CLC2006 checking procedure was done in all 38 participating countries with help of the InterCheck software, because it can be used for checking CLC2006 and CLC-Change databases in any file format that can be added to ArcView program as a theme (ESRI shapefile, ARC/INFO coverage, AutoCAD drawing etc.), i.e. not only those that has been prepared with InterChange.

The TatukGIS Developer Kernel is a comprehensive GIS Visual Componenet Library for the custom development of stand-alone, embedded, and client-server applications using object-oriented languages. The Developer Kernel is generally oriented to open standards and designed to comply with a number of OGC (Open Geospatial Consortium) standards.

LUCAS data

LUCAS (Land Use/Cover Area frame statistical Survey) is co-ordinated by the Statistical Office of the European Commission (Eurostat). Land cover refers to the bio-physical coverage of land (e.g. crops, grass, broad-leaved forest, or build-up area). Land use indicates the socio-economic use of land (e.g. agriculture, forestry, recreation or residential use). LUCAS land use/cover data are used among others to calculate Sustainable Development Indicators, Land take and Agro Environmental Indicators to support spatial planning in Europe.

CLC2000 Support Package


CLC2000 Support Package has been developed for Remote Sensing Centre of Hungarian Institute of Geodesy, Cartography and Remote Sensing (FÖMI), in order to help the implementation of the European CLC2000 project managed jointly by the European Environment Agency (EEA) and Joint Research Centre (JRC). The software operates under ArcView environment. ArcView software is designed primarily for viewing GIS databases with tools for creating maps, menus for handling databases and graphical editing tools. At the same time, ArcView includes only limited and less effective tools for creating and filling new polygon databases or modifying existing polygon databases. As a solution, CLC2000 software under ArcView provided a cheap tool for quick and comfortable editing and handling of CORINE Land Cover databases.

CLC2000 software was a macro package written in Avenue, ArcView's own macro language. The software was a supplement to ArcView 3.2/3.3 GIS. The use of the CLC2000 Support Package significantly facilitated updating, change detection, quality control and correction of land cover databases by means of computer-assisted visual photo-interpretation. The CLC2000 software was used by 15 European national teams, out of 30 participating countries for interpreting changes in CLC2000 project.


Avenue is an object oriented scripting language and development environment fully integrated with ESRI ArcView GIS software. With help of Avenue user can freely customize the user interface of ArcView, and can create complete applications for specific GIS tasks. Unfortunately ArcView came outdated. Last version 3.3 released in 2002, and since 2005 ESRI provides only limited support for this product. Recent ESRI software ArcGIS uses Visual Basic as built-in scripting language.
