Desperate for some guidance on this. I am trying to convert ASC files to Polygons. I have a load of floating point ASC files, some brief details on them;

Columns/Rows: 2000/1000
Bands: 1
Cell Size 2.5/2.5
Format: AAIGrid

The ranges contain numbers to .10 decimal places and its very important I keep these to at least 3 decimal places in the final polygon (for symbology).

I was thinking that i need to use spatial analyst and convert to raster and then use the conversion raster to polygon tool. Can one of you please give some guidance on how i can do this and maintain the values.

Thanks in advance
