CLC2018 Support Package

 

  • Red colour indicates new or significantly modified services in InterChange and InterCheck version CLC2018 4.0 (11.2017) compared to version CLC2012 3.1.3 (06.2014).
  • CLC2018 Support Package provides all menus, pop-up texts, information lines and dialog boxes in English.
  • Detailed help, context sensitive help and printable user's guide (all in English) are inherent parts of the software.
  • Program works fast and stable with huge polygon databases.
  • Software supports Sentinel raster images provided for the CLC2018 work by the ESA/EEA.

InterChange services

 

Creating new project and working environment

  • With the InterChange program the user can create a new directory and file structure for each map sheet – optimized for change detection – on which the interpretation can immediately be started.
  • All loaded layer can transformed on-the-fly to the initially specified coordinate system of the map windows.
  • User can add WMS layer from web map server. Batch mode WMS layer loading available.
  • Multiple files and batch mode raster layer loading available.
  • Advanced satellite image colour tuning can be used. If image contains clouds or larger water surfaces, colours can be set based on an interactively selected area.
  • A full country/full working area map sheet grid shows the actual status of the whole mapping task.
  • Countries that use non-standard mapping procedure, can reverse the order of the Revision and Change windows, and can modify the base year captions of the map windows.

Polygon editing functions

The interpreter can easily

  • correct errors in the CLC2006 database and create new polygons in the Change database;
  • cut out a new polygon inside a polygon;
  • split a polygon into two parts;
  • fully reshape a part of a polygon border in one step;
  • unify two neighbouring polygons; delete polygons in Change database.
  • Flashing of the edited polygon can be switched off/on in the Default settings window.

Tools supporting interpretation

  • InterChange program displays Revision database and the Change database in two separate map windows continually synchronising their content.
  • Minimap window shows the current visible map extent on the whole map sheet area.
  • Pan tool can be quickly used by dragging map area with middle mouse button.
  • All data belonging to a selected polygon are shown in the CLC data window. CLC code and area are visible in the status bar too.
  • The program keeps checking for interpretation rules and warns the interpreter when errors occur during data editing and data input.
  • Edited data are integrated into the corresponding database with a single click.
  • Interpreter can change from screen divided between two windows to full screen view of one window with a single click.
  • The environment of the selected polygon(s) can be masked out.
  • Data can be edited quickly (usually also by using keyboard shortcuts).
  • CLC code can be selected from a list box.
  • List of valid fourth level codes can be added in the Default settings window.
  • A short comment can be added to polygons.
  • Interpreter can modify also CLC2006 code of change polygons, if needed.
  • Interpreter can add technical change attribute to change polygons.
  • Colour of polygon outlines as well as colour and size of code labels can be set separately for the two databases. Settings can be saved to disc and loaded into another project.
  • Centre of the workspace can be positioned to a user specified XY coordinate.
  • Actual working area (coordinates and scale of the active map window) can be saved to hard disc and can be reloaded with a click.
  • Interpreter can search for polygons according to several characteristics, such as CLC code, change type, comment, error, supervisor's remark, progress status, area limits, change probability or technical change. Program specially supports serial search by error correction.
  • InterChange supports importing, searching and fulfilling supervisor's remarks created with InterCheck software.

Main error prevention functions

  • When selecting and writing in the CLC code, the program does not allow the use of invalid category codes.
  • When editing polygons, the program warns if the created polygon is smaller than the size limit or is a multipart polygon.
  • Non-adjacent polygons cannot be unified.
  • An error checking and correcting tool helps to find and correct overlapping or multipart polygons, selecting polygons below size limit, with shape error, with invalid or zero code. If source data has self crossing errors, program creates a point database to show these points. Error checking accepts small polygons of the complex change areas.
  • Error checking procedure signs polygons, that coarsely violate the rule of the minimum polygon width.

Information support

  • Visible extent of the revision database can be exported in KML format for viewing it in the Google Earth software.
  • LUCAS land cover and land use data and field photos can be viewed with a single click (if data available on the computer).
  • Data table can open for all vector type database.
  • With optional error colouring, the interpreter gets an overview of areas yet to be interpreted, small polygons, polygons with shape error or without code.
  • Code colouring shows interpreted areas with standard international CORINE colour coding.
  • Work status colouring allows the interpreter to follow the progress made in change detection, the size and position of areas yet to be examined. Work status colouring is visible in the Change window too.
  • Code change colouring helps identification of those changes that are less likely to occur, thus might need further consideration.
  • Code labels of polygons can be switched off/on and can be refreshed.
  • A temporary code label can be placed anywhere in the polygon.
  • Detailed description of a chosen code can be obtained in a separate window with a single click.
  • Description might also be available in national language instead of English (the content of the source file being the responsibility of the national project leader).
  • During drawing a line or a polygon status bar shows distance between last click and current cursor position.
  • With the area measurement tool the area of a planned polygon can be quickly estimated.
  • Advanced code, polygon area and code change statistics available.
  • Wider polygon outlines as well larger code labels can be switched on before creating screenshots for documents and reports.
  • The content of the active map window only – not the entire screen – can copied in the clipboard with a single click, for using in documents.

InterCheck services

 

Creating new project and working environment

  • InterCheck can use directory and file structure created by the InterChange program.
  • All loaded layer can transformed on-the-fly to the initially specified coordinate system of the map windows.
  • User can add WMS layer from web map server. Batch mode WMS layer loading available.
  • Multiple files and batch mode raster layer loading available.
  • Advanced satellite image colour tuning can be used. If image contains clouds or larger water surfaces, colours can be set based on an interactively selected area.
  • Countries that use non-standard mapping procedure, can reverse the order of the Revision and Change windows, and can modify the base year captions of the map windows.

LUCAS Photo Viewer services

 

LUCAS photo viewer program displays the main data and field photos (if any) of the LUCAS point last selected in InterChange or InterCheck program. This software is built in part of InterChange and InterCheck. It can use LUCAS data only of a specific format and JPG files named according to the naming convention specified in the appropriate LUCAS manuals. LUCAS data must be in ArcView shape file format.

The window contains two pages, among which user can switch by clicking their page tab on top of the window or with keyboard shortcut Ctrl+Tab.

  • On page Thumbnail images field photographs taken into the four main directions (North, East, South, West) are displayed besides main data.
  • On page Zoom image the enlarged view of the image taken to the selected direction is displayed besides the main data. The image can be further enlarged if there is a need to examine it more in detail.
