you try to open a locked workspace, it will automatically be opened in read-only mode, which will
prevent you from overwriting the original workspace file when saving.
• Center on Cursor when Zooming with Mouse Wheel - when this option is checked (or when
holding down Ctrl) and you rotate the mouse wheel over the map, the map will zoom in and out and
maintain the location under your cursor at the same location rather than just zooming in and out on the
current screen center.
• Swap Zoom Direction Using Mouse Wheel or Hot Keys - when this option is selected the direction
of zoom when scrolling the mouse wheel or using the Page Up/Down keys will be reversed.
• Export: Snap Export Bounds to Pixel Boundary if Possible - when this option is checked the
bounding box for an export will be adjusted so that the top left corner of the bounding aligns with the
top left corner of a pixel in the imagery being exported. This is useful to eliminate any visual
sub-pixel shift due to mis-alignment of the export bounds and the pixels in the input imagery.
• Export: Keep Pixel if any Part is Inside Crop Area - when this option is checked and you are
cropping a raster/elevation export to a selected area feature, an exported pixel/cell will be kept if any
corner of that cell is within the crop area rather than the default requirement of the center of the cell
being in the crop area.
• Disable Display of Pan Arrows on Map Edge - when this option is checked, the arrow cursor that
displays near map edges when most tools are active to allow easy panning are disabled, thus allowing
use of the active tool all the way to the edge of the map display.
• Always Display Lat/Lon in Status Bar in WGS84 - when this option is checked the lat/lon location
displayed on the right side of the status bar will always be in the WGS84 datum rather than whatever
datum is selected on the Projection tab of the Configuration dialog.
• Disable Automatic Interpolation of Resampled Exports - if checked, exported raster layers will
only be interpolated if the anti-alias (interpolation) option for that layer is checked, rather than
interpolation occurring for any reprojected or resampled export.
• Disable Automatic Interpolation of Zoomed-Out Display - if checked, this option disables the
automatic interpolation/anti-aliasing done when zoomed way out on raster/imagery layers. This can
increase the drawing speed when zoomed out on data, at the expense of a worse display for most
maps.
• Auto-Fake Location of Unpositioned Rasters - if checked, this options causes the location of any
un-positioned raster files to automatically be faked to allow display. This means rather than being
prompted to rectify, fake the position, or cancel the load, the "fake position" option would just be
chosen automatically.
• Export Old Format PRJ Files - if checked, this option specifies that the old, mostly unsupported,
ESRI PRJ format be used when PRJ files are saved rather than the default new WKT projection
format that is used by default.
• Include Datum Transformations in PRJ Files - if checked, this option will cause any generated
WKT PRJ files that use a datum based on a 3-parameter Molodensky or 7-parameter Bursa Wolfe
transformation to include that transformation as a TOWGS84 field in the PRJ file. Note that some
products (i.e. ESRI ones) won't accept a PRJ file with the TOWGS84 field, which is why it isn't
always included.
• Create PRJ Files with .PRJ After Original File Extension - if checked, this option specified that
any export that generates a PRJ file will append the .prj to the entire filename rather than replacing the
file extension with .prj. So if you exported a file named test.ecw with a PRJ file, you would get
test.ecw.prj for this export rather than test.prj.
The Restore Default Settings button will restore all Global Mapper settings from the Configuration dialog to
their default values.
