1 Hammerman's HQ is a red and gray structure with a red door, four rooms as corners, and a second floor with an antenna.  Dr. T's HQ has a similar design to the level 11 HQ, but the windows and crates are replaced with two green pipes. Instead of a satellite, a rotating porthole-like structure is located on top.
The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. This simple concept is complicated by the curvature of the Earth 's surface, which forces scale to vary across a map. Because of this variation, the concept of scale becomes meaningful in two distinct ways.
The RF says that 1 of any measurement on the map equals 1 million of the same measurement on the original surface; for the example above 1-foot equals 1 million feet or 1 cm. equals 1,000,000 cm. This is the form of scale commonly used in the Map Collection. A good quality map should have both the RF and Bar Scales.
