I have a new map pack on sale as part of my Fantastic Maps line. It's called the Tribal Encampment and details a tribal camp laid out around koppe in the savannah. It's on sale in the Paizo store for $1.99 for which you get:

• high resolution jpg at 100 pixels per 5', both with and without grid.
• printable multi-page pdf for printing out at the gaming table, in colour and printer friendly greyscale.
• maptool campaign files for 4E and earlier versions.

Here's a low res preview of the map with grid:
