Recently "upgraded" from Auslig to Natmap 250k series. In my opinion they seem to be the same product rebadged. Have not found the" 250 new maps" or "the better quality". I will be talking to Natmap in the new year about the problems when zooming in etc and was wondering if any one else has problems with this product. If you have the Auslig Cd, not really worth upgrading.

John the new maps are a significant improvement and so is the resolution. Are you sure you are still not looking at the old maps?

There are no problems zooming and nobody on the OziExplorer software group has reported any problems. To date, I have only heard compliments, no complaints.

If you have problems zooming, this would be an issue of your video driver, not the Natmap maps. Suggest you go to the website of your video card manufacturer and download and install the latest video driver and make sure you have the correct make, model and type of your video card.

What version of Windows are you using, and what make and model of video card do you have with how much onboard ram?

Ozi, thanks for the reply. How do I find out what video card I have? Using Win ME with 128 meg of SDRAM in a lap top. Hope you can help me.

John, what brand and model of lap top do you have?

The reason why you are having this issue with the new Natmap maps, they have taken the DPI (from memory) 150dpi to 250dpi.

Do you use OziExplorer software at all?
http://www.oziexplorer.com
If you do, download the Img2OZF convertor and convert all your ECW to OZF2. This is based on PNG and only loads the screen image to memory, not the whole picture file like other formats. PNG and OZF2 page the memory that quickly, you would not know it is happening. What is more, you get 10% zoom steps. You would not (or I should say, highly unlikely) to have any issues whatsoever with OZF2 or PNG.

If you do not have OziExplorer, I don't know a program that will bulk convert from ECW to PNG.

Laptops older than say 12 months were always natorious for poor video speed and memory. However, the latest version video drivers should always make a decent improvement.

Hello - wouldnt bother converting ecw to ozf2 (unless you have to for CE) or to png. Ecw also only loads screen section to memory and has HEAPS smaller file. Loads fast. Can see no benifit in any other image format.
Merry Christmas

Hey Ozi, if you got a CD burner, I'll hold a backup copy of them here for you so if yours get damaged I'll have a spare set for you here :D

To find what video card is fitted in your computer go to settings,contol panel,systems,hardware,device manager & select display adaptor. This window should give the video card description. From that you can possibly try microsoft.com for an update or try a website at driverguide.com & look for an up to date driver for your operating system.

John, Can you see the new and improved maps using the Natmap raster viewer?

If so, the problem may be caused by the *.map files that Ozi uses to define the datum, + calibration data and point to the location of the ECW files - If you haven't changed them they may still be pointing at the Auslig files (Assuming you have loaded them to the hard disk)

Try deleting all of the *.map files for the Auslig maps and reloading with the Natmap ones from the Ozi website.

You can check this by opening one of the *.map files in a text editor - the path to the ECW files is in line 3 - Check this matches the path to the NAtmap files, not the Auslig ones....

Hope this helps, Merry Christmas!
Pete

Thanks for the reply. Had to delete/uninstall old maps etc before I could load new series. So presume seeing new maps.

John, I had the zoom problem too. The specs say use 600 x 800 screen resloution, so I changed mine from 1024 x 768 & it worked fine.
