It would be nice to set land to look like basic land types. Example types: Desert sand; snowy; swampy; rich grassland; yellowy fields; mud; or dry, cracked land.
Opening it to any texture would likely be a nightmare, so either provide a click box on the land menu for basic types, or otherwise limit the textures people can put onto land.
Some people have resorted to tiling areas with cubes to emulate things like golfing fairways/greens or swamps.... Perhaps this woud be a better way to customize your basic land look.
Bonus points: Allow the land type to be changed with a library call. Then people could have the land change according to 'seasons' and what not
Also, after you add the weather system, you can possibly have the land type take on modifications relevant to which weather type is going on or has occured recently.
So you might find puddles in your grassland after a rain, or your yellowy field might become green after a rain Obviously, on the sims where policies can be set by residents there would be a a set of options for people to vote on, regarding allowed land types, etc
