I would like to use the Tiler transformer to create 100x100m tiles. How do I specify this? They only size option I see is listed as "ground units".

Tiler transformer size by meters

The units used are whatever units your data is in. So if your data is in meters, the Tiler will interpret the tile size as meters.

How do I define or tell what units my data is in?
It's based on the projection/coordinate system.
If you data is in LL-WGS84, the units is degrees, it it's in most UTM projections it's meters.
The coordinate system gallery lists the units for each coordinate system, if you don't know.

If your data is not in meters, you can reproject to _AZMEA_ or other metered coordinate system that best suits your data, run the Tiler, and then reproject back to your original coordinate system.
If your don't want to reproject your data (and there are degradation issues around floating point values) you can use a boundingBoxAccumulator, reproject that, tile it, reproject to the original coordinate system, and use the results as a clipper on your original data.
