Upon request of several users I have checked compatibility of Mapwel IMG filesand Mapset toolkit.To make map in IMG format exported from Mapwel compatible with Mapset Toolkit,you have to do the following:- Use main menu >File >Properties > Map ID tab to set user defined ID to map.Check 'User Defined' option and insert some 8 digits map ID number. This numbermust be unique among all maps in GPS. Check the 'Use as a file name' option.- On the same tab check the 'User Defined' map set data option. Select some MapFamily ID and Product ID.- Uncheck 'User Defined Styles' in the map parameters tab in the same window toavoid merging of user styles file to the main map file. If you want to use userdefined styles with your map, export styles into TYP.txt file with use of mainmenu > Objects > User Defined Styles > File.- Make sure that map has 'Background Area' object which defines the shape of themap. If there is no such object, draw it manually. It can have irregular shapeor it can be just rectangle.- Export map into IMG file format.- Load IMG file to Mapset Toolkit. Load TYP.txt file into respective box.Previous steps were made to ensure compatibility with Mapset Toolkit, whichshould be achieved at this point.
