[GRASS-user] LiDAR dtm analysis

[Shane Carey]

Hi All,

I have some repeat surveys of LiDAR data over a raised peat bog (
http://www.wesleyjohnston.com/users/ireland/geography/bogs.html)

and we are trying to do some analysis on the bog over time. The problem is,
some surveys were conducted during the winter (Hence bog expands due to
more rain) and some were conducted during the summer (Hence bog shrivels
due to a lack of rain).

I was wondering would anyone know if or have any ideas on a way to
normalise the dtms to one level so that we can compare like with like.

Thanks
