Phnom Penh is a former French city of boulevards and small streets. Of course, all the boulevards in the Google Map image attached need to be included, but most of the streets do not, with the exception of Preah Sisowath Quay, and streets 19, 21, 51, 57, 63, 102, 110, 154, 163, 178, 214, 217, 240, 294, 308, 310, 360, 380, which should all be included along with landmarks.
Please note the samples. The first is the extent of the map we need. The other two maps are examples of cool designs – obviously, they are extremely detailed and we don't need that level of detail, but they are stylized in a way that make them look unlike typical tourist maps or the Google maps we're all so accustomed to seeing.
