Hi psvialli,
I'm sorry for my slow reply. Unfortunately, the bad news is that L3DT currently does not have a nice user-accessible way to change one land type to another across a whole map. However, I think you might be better served in changing your climate so that the land type you get is the one you want. To do this, copy the existing climate (see the 'Resources->Climates->Climate manager' menu option), then edit the relevant land type (i.e. sand), and set that land type's material to 'std_sand_yellow' (to match the setting in the temperate sand). After doing this, please remember to apply the new climate to the entire design map using the 'Operations->Design map->Modify parameters' menu option, or else the 'apply to all' button in the design map brush.
Best regards,
Aaron.
