Searching for Family Farms

I am trying to locate a couple of farms where my ancestors used to live. Both are in the Ringsaker, Hedemark area of Norway. One is the Lille Amblieie Gard and the other is the Smedstad Gard. I understand the Smedstad farm can be seen from the highway from Ringsaker to Lillehammer but that Lille Amblieie is more difficult to find. Does anyone know of any maps that show the location of these two farms? Does anyone know of any other way to locate these farms if maps do not exist? I am planning a family heritage trip to Norway this June and would like to visit these places. Thanks in advance for any advice.
