In Map mode the editor connects via Internet to the SNSB Google Maps service or alternatively to the Open Street Maps service, regarding on the GIS-Editor Settings, and displays an online map which can be moved, zoomed and switched as usual. The status area shows the Image or respectively the Image symbol. The size of the map area adapts to the size of the working area, even when resizing the window.

In case of Google the controls for moving, zooming and map type are displayed by default. The overview window in the bottom right corner can be switched manually. The map can be adjusted to the user’s needs as follows:

  • Select map area: Press and hold left mouse button and move the mouse
  • Zoom map: Turn the mouse wheel (if any), double click (left or right mouse button) on a location
  • Switch map type: Use Google map type control
  • Hide Google controls: Click right mouse button to hide, left mouse button to show them again

In case of Open Street Maps the pan and zoom control is displayed by default. It can be switched off or on by clicking the left mouse button anywhere within the map area. The layer switch control is hidden and can be opened by pressing the Plus or closed again by pressing the Minus button on the right side. The map can be adjusted to the user’s needs as follows:

  • Select map area: Press and hold left mouse button and move the mouse, or use the OSM pan control
  • Zoom map: Turn the mouse wheel (if any), double click (left mouse button) on a location or use the OSM zoom control
  • Switch map type: Open the layer switch and select a layer
  • Hide or show pan and zoom control: Click left mouse button to toggle the control

If an appropriate area has been selected, just press the Add button Image, then the area will be scanned and added to the Sample List as a reference map. A little image of the map will appear on the toggle button in the Sample List. The controls should be switched off before adding to get a neat map image.

Then the mode will be switched to Shift mode automatically and the status symbol will change to Image indicating that world coordinates are present. The screen and world coordinates will be shown in the status lines if the mouse is moved over the map surface.

The maps are subject to the Mercator projection, which is the GIS Editor’s precondition for every bitmap used as a reference map. While the screen coordinates are linear in horizontal and vertical direction, the world coordinates are non linear in vertical direction.
