Creating an American Football field

I want to create a landscape with the same dimensions of an American Football field. The dimensions are 100 yards (91.44 m) (300 feet) long between the goal lines, and 160 feet (48.8 m) (53 1⁄3 yards) wide. What should I set the X, Y, and Z scales to? It also wants me to select the Section Size, Sections per Component, Number of Components, Overall Resolution, and Total Components. And recommendations?

There is no point using the landscpae for something so small.
Make a mesh instead. Being its flat, all you jeed is 4 points and 2 tris.

Also, you shpuld probably read up on the documentation for the landscape to learn what the tiles and components are/do.
