Hi,

That is surely WGS84 you are using with a Degree Decimal Minute setting. You will have some problems in the conversion with the "o" and " ' " characters. You should set your coordinate systems to "World" to achieve your quest.

Cheers.

hhyoong:
Thanks once again!

I will try it out and get back to you.

hhyoong:
Hi!

Can I know is this setting correct?

GCS_WGS_1984
Datum: D_WGS_1984

Also, what is Z-factor? I tried few times but I don't understand the difference.

My Z value range from 0.02~ 0.5. But when I key in 0.1 as my Z-factor, the legend shows from 0.168~0.237. I am using IDW mode

Please guide. Thanks

MyGIS:
Hi,

Don't bother about the Z value as you would not need to use elevation you will be working on 2D only.

Cheers.

hhyoong:
Thanks for the reply.

How should I show my parameter level on the map?Aren't the colours indicate the level of the impurities? I only see Z values as the thing that shown in the legend which verifies the range of impurity.

Please guide again  :)
