File Write Calibrations : Writes a set of calibrations, every one of .map, .tfw, .cal, .jpr, .gmi, .mcd, .txt except the input type (all  types are written if an image has been calibrated).  Calibrations are always written as WGS84, Latitude and Longitude. You may choose which calibrations  to write in Edit>Preferences.  If the program has  altered the map image by edit functions then the map image is written too. Default is to write the image as 8-bit PNG but use Edit Preferences to write 24-bit PNG or JPG. If writing to import into Quo, warp the map to Latitude/Longitude first and use the defaults of 8-bit PNG - any padding from warping will be transparent to Quo.

File write Trekbuddy map : Writes a set of tiles in a format compatible with Trekbuddy : in "<mapname>_tiles" the .map and a .set file and  a SET of map tiles. Tiles are .png whatever the input image type. If the map is in the UK then the .map file may be written using British Grid Coordinates. Alternatively, write as Trekbuddy TAR format in <mapname>_tars with map scale and three zoomed out scales (1/2, 1/4, 1/8). These are given zoom numbers for reference only - no reprojection takes place. The calibration file has the projection of the original map. This format is accepted by Locus. The map does not suffer from the potential loss of quality caused by reprojection.

File write Garmin Custom Map : Writes a set of tiles in a format compatible with Garmin Custom Maps : in <mapname>_tiles the doc.kml and a  files folder of map tiles. Tiles are written as .jpg : other image types are converted automatically.. Use 7-zip file manager to join doc.kml and the files folder into  a zip-format file with file type .kmz. The map does not need to be oriented North-South. If 'Advanced Garmin Tile Control' is checked in  Preferences a form showing the tiles is opened. The number of tiles can be adjusted and individual tiles deselected (if required) by clicking. If 7-zip is installed on your machine use Edit>Locate 7-zip to 'Open' 7z.exe and the program will invoke it automatically. The 'tiles' need no further georeferencing.
There is a sample map here - thanks to the Libre Map project for the map.

File Write Garmin Custom Route Map : The program analyses all tracks that have been loaded by Track Manager and are visible on the loaded map and makes a Garmin Custom Map to encompass these tracks and as little else as possible. This is ideal for a long trail where the number of tiles is far less than would be needed normally. Note that the tiles that make up the map will be different shapes. The tracks are not drawn onto the map - use Edit>Load Track/Waypoints overlay if you want them to visible on the Custom Map

File Write JNX File  See here for details of JNX files. Before writing, the map must be aligned true north. If this is not already the case then use Edit>Warp Map and choose Latitude/Longitude

File Write Map for Mobile Device : Writes one or more sets of tiles for Andnav, Maverick, Back Country Navigator or OSM Tracker applications. Also Locus, AlpineQuest, MyTrails and Rmaps. These use the Google Earth standard spherical Mercator projection with zoom levels where level 0 is the whole earth in one 256x256 tile, level 1 is 4 tiles, level 2 16 tiles and so on up to about 17 with tiles numbered south and east from a point north of the Bering Strait. The program calculates the nearest matching zoom level and offers a range. Each zoom level is displayed on screen with the option to save space by deleting tiles (e.g water in the centre of a lake) and each deletion is inherited by the next zoom level. The map has to be reprojected to the spherical Mercator projection - this process may take a few minutes.

Most Mobile Atlas formats are written as palettised PNG files but preference Write as JPG applies to SQLITEDB and OSMTracker; OSMTracker is only palettised if the Reduce to 8 bits preference is set.

When writing a mobile atlas, if the tile of the same address already exists in the output folder then the content is merged so that a seamless map can be created.

Note that when you load and switch to an offline map to some systems - Locus is an example - the system is not positioned over the map and all you will see is a blank screen. Look for an option such as 'centre map' or seach for a place you know is on the map.

File Write Androzic MAP+OZF2 : Writes two files that make a map for Androzic or mobile versions of OZI Explorer (e.g OZI Explorer CE)

File Write Maps n Trax : Creates a directory with data compatible with the Iphone application Maps n Trax. The map is reprojected to Spherical Mercator aligned North-South.

File Write BitMap : Creates a directory with data compatible with the Iphone application BitMap. The map is reprojected to Latitude/Longitude aligned North-South. A file .bitmapname is also created containing the calibration information.

File Write Magellan/Triton RMP : Reprojects to Latitude/Longitude WGS84 if necessary then writes a Raster Map file that can be used with these devices (e.g Explorist). RMP Preferences allows the Map Provider and Map Group details to be set.

File Cut Map into Tiles : Uses the Tile Width and Height to cut the map into pieces. Each piece is written withits own .map calibration file

File Write KAP Chart : Writes a file (*.KAP) in a format that is compatible with programs that read BSB/KAP charts. The image is reduced to 3,7,15 or 31 colours (set in Preferences) and reprojected to Mercator WGS84 aligned true North. The basic implementaion is quite simple. For compatibility with Klein Sonar software, you need a licence for the Sonar Edition. Please contact the author for details.

File Write GEOTIFF : Reprojects the image to Mercator or Plate Carree, saves it with calibration information (single point and scale factors). By default the GEOTIF has LZW compression - this can be turned off in Settings>Output.. Falconview is an application that will not accept LZW compressed files.

File Write ECW : Reprojects the image to Plate Carre (unless it is Mercator), saves as a GEOTIFF and then calls GDAL to convert to ECW. Note that changes to the licence mean that only GDAL 9 and earlier versions will write ECW files. Earlier versions are here
