Thinning data in a raster model

Hello,

I have a .gdb surface model of a section of the Fraser river (British Columbia) that I am using for a numerical modeling project. The problem is, that the dataset is on a 3mx3m grid for a total of ~8 million data points. For my purposes, I only require a resolution of about 25mx25m.

I am a new user of ArcGIS so I am not sure about the proper way of thinning this data set is. Does anyone have any suggestions? I would really appreciate it.

I should also mention that I am running ArcGIS 9.3, and that the end goal is to obtain a xyz dataset of 25mx25m resolution.

Thank you!

Steven
