Installing NATMAP Digital Maps onto OziExplorer

Hello - that works and calibration is spot on but only draw back is that the corner markers, which define the edge of the map image, may not be in the right position. Using the method you describe will result in the map borders being placed at the extreme 4 corners of the image which may or may not correspond to the actual map boundary. The position of the corner markers is very important if you plan on using moving map as it defines when the edge of the actual map boundary is reached and initiates search for the adjoining map.

This is only relevant for the individual map tiles that have a white border with legend, not the mosaic. The 250K map (calibration) files made available on the OziExplorer web site have the corner markers in the correct position. So best to use these if you can. If you choose the ecw import method you will have to manually adjust 4 corner markers on every map (well you don’t have to but..)

It is a while since I purchased the Natmaps in that format. These days I just download my Natmaps from the GeoScience website for free. The plus about the maps from the website is that you know you are getting the latest maps and the big plus is they dont have any white borders, so when you import them the border markers are all in the right place.

No worries - just thought Id mentioned the corner marker issue - obviously doesnt apply in every instance but it can be a trap for new chums. Nothing worse han getting out bush and finding moving map wont work properly.

You have 2 options. You can either place the map files in the same folder as the image files. This way you dont have to worry about changing the map file to find the image file as Ozi always looks in the folder of the image first.

The 2nd way is to place the map files in a separate folder. If you prefer this method, you will need to goto 'File ' 'Change Image File Name, Path & Drive'. There are 3 options in the drop down window. The best one is the middle one ' Change Image File Path for all Maps in selected folder'.

Hello

How you choose to organise your maps and calibration files is obviously a matter of personal preference and circumstance. I prefer to keep all my map images and calibration files together (though I have different map sets/jobs in separate folders). Main benefit is that you can move them (map image and calibration file) around between folders, drives and PCs without having to change a thing. In my case I don’t see any benefit in keeping them separate and in fact it would be a major PITB if I changed computers/drive/file path - it would take me hours if not days to convert the path of all my maps.
