Ozi Explorer And Mr Sid Image Files

[BeautyLover]

I want to produce small calibrated images from 500mb file of the .sid format using ozi explorer.

 

What I am doing now is capturing the screen, loading the image as a non calibrated map, then calibrate it by running 2 instances of ozi, one to read featured points coordinates and the second to calibrate the map.

 

It is tortures to do this way, am I missing something.

 

thanks

I don't use Ozi that much but if you go to the Optional Extras page on the Ozi website and look at the "MrSid Image Loading Support File" it might be what you're looking for.

An easier way to do this is after you do your screen capture, place 3 waypoints on the currently loaded map as if you were calibrating the map, save the waypoints, then load/calibrate your new map image and when you select point 1, click the "Wp" button and a window will pop up with the 3 waypoints. Select one to automatically enter the coordinates for point 1 and then set point 1 on the map in the same spot where the waypoint was. Repeat this for the other 2 points and save.

Thanks for the help,

 

thanks for the link. I concluded that ozi is not capable of exporting portions of MrSid files.

 

I guess that the solution is to down load smaller Mr sid tiles, I need to search the nasa landsat site for that possibility.

 

Poindexter, I was trying to avoid the calibration process all together because the coordinates read by MrSid is deadly accurate, and when I do the calibration my self the gps position drift slightly no matter how many points I use for the calibration.

 

Many thanks

I found a utility that called ozimapmerge that can merge as well as break maps into smaller pieces. The produced maps are born calibrated. This is exactly what I was looking for.

 

If you use ceozi this will be an ideal tool.

 

Many thanks

One more thing

 

ozi mapmerge will produce file extension of ozfx3 which will run on oziexplorer and only on the latest development version of ozice (1.11.6d)

 

if you have an earlier version of ozi ce it will not understand the ozfx3 file format.

 

I find this approach the most powerfull and most accurate approach for off road navigation for countries other than the USA, And Canada
