Hi,

In this case, your are mentioning about another problem which is converting from RSO to Cassini.

As for the WGS84 to RSO, ArcGIS 9.2 supports Kertau and Timbalai very well. This would mean that the conversion from RSO to WGS84 can be done either on the fly or using the ArcToollBox . Cassini is not supported by ArcGIS .

As for the conversion from Cassini to RSO, you can check here http://www.gis.com.my/scripts.htm . Item "3" of the list would direct you the appropriate link (not sure if the link is still working or not).

If it does not please let me know.

Just remember when making the conversion that you will never get a 100% precise conversion since all the coordinate systems are using general mathematical formulas that generate distortions when the are is too big.

I hope this would help.

Hi mr_hustla,

I have multiple solutions ... First question I need you to reply to help me guide you is : are you a student? Which university are you in?

I hope you could reply to me ASAP.

Thanks.

Hi again,

I used to make it available on this website years ago until the owner of the script asked me to put a link to his website instead.

The ArcView 3.x extension is available here: http://www.mygis.com.my/mygis/malaysia_projection.zip .

Sorry, I forgot about this.


Thanks.

OK, in this case, if you are working only on converting from RSO to WGS84 and the other way around, you can download FME from safe software:

www.safe.com . Once you download, please p.m me your 10 digits registration code and I will give you a 14 days license. If for some reasons, you find it useful, then I can try to get you a 1 year license for your faculty.

Please keep me posted.

Hi,

No, it is a one year renewable license no charge for universities. Get the 14 days license first and see what you can see before you decide.

Thanks.
