Thanks to the various people who helped me find bathymetry in order to create a map of Europe during the Late Pleistocene.
Now for a more difficult question. We’d like to mask out areas covered by ice caps for our cost surface analysis and models. I’ve found various images of the extent of ice sheets in Europe, but no georectified, reasonably accurate DEM or vector maps of the ice—primarily the Baltic ice sheet and Alpine ice cap.
Has anyone run across such maps? The best I’ve found so far are published on the Quaternary Environment Network site <http://www.esd.ornl.gov/projects/qen/nerc.html>, but are simply images and rather coarse ones at that. These are so coarse that I fear that digitizing and georectifying these would be highly inaccurate and make our results equally problematic. I know that there has been a lot of mapping of the ice margins in Europe as well as North America, but can’t find any GIS data for it.

hi
I think i can help you, i have some map of extent of ice in pleistocene (shp. for poland area).
I can also ask my colleague who is specialist of Pleistocene geology about maps for europe.
best
maciej
p.s. SHP file i will send you separately

Hi Michael,
one of best sources about ice sheets in Europe is [1]. Printed edition
has a CD with data in shp format, altought those data are a bit
outdated now, also for some unknown reason those shapefiles contain A.
Raukas et.al. (Estonia) version about ice margins in Latvia instead of
V.Zelcs et.al. (Latvia) provided interpretation.
There are some efforts to unify recent findings ant they
interpretation in form of more accurate map in project DATED [2]. You
could contact with them using email provided in that pdf.
And if You like, You could also present Your research at next INQUA
TEPRO Commision Peribaltic Working Group meeting in Poland.
Unfortunately I can not provide more info about dates etc., but
colleges form Poland should know better
