Map Tile Export

Hi! Does any know know good tutorial for exporting map as tiles? I can not find any, and I have problems. I assume the only way to do so is to use Data Driven Pages. I have 3 layers on the map, and I want to export each on as large 10000x10000 tiles. One of the layers is dem map which uses 32bit float, and for Data Drive Pages all I can export are 8bit images.

Is data driven pages really the only way to export map layers as large tiles?

I tired using this code to export:

mxd = arcpy.mapping.MapDocument("CURRENT")
for pageNum in range(7014, 7016):
mxd.dataDrivenPages.currentPageID = pageNum
arcpy.mapping.ExportToJPEG(mxd, r"C:\Temp\ParcelAtlas_Page" + str(pageNum) + ".jpg", '', 10000, 10000, 1000)
del mxd

But that is crazy, final result comes up in random sizes with white marghin around the map, I noticed that for some reason 'Page and Print Setup' influences how the final image looks, but it has no suqre options, only stuff like A4/A5 paper. Did I forgot some important step before enabling data driven, to make sure it properly renders all pages as squares? I need to render every page at 1:1890 resolution, which is its original

Konstantin, there is a lot to read and no quick fix that will suit all requirements

What do you mean by "tiles"?

Are you trying to cut up your data into more manageable sections retaining the same format and datatype?

Are you trying to create a series of map images from your data ?
