The invention relates to a method for creating an environment map for an autonomously traveling ground processing device. A first ground processing device detects first characteristic data of the environment and processes the first characteristic data of the environment into a first environment map. A second ground processing device detects second characteristic data of the environment and processing the second characteristic data of the environment into a second environment map. The first and second environment maps are combined into a common environment map. In order to be able to splice environment maps of a plurality of robots even when an overlap region is small, the first ground processing device recognizes an object as a positioning point and stores position information of the positioning point in the first environment map, and the second ground processing device identifies the same object as a positioning point, stores the position information of the positioning point in the second environment map, and combines the environment map into a common global environment map according to the position information of the positioning point. The invention also relates to a system consisting of the autonomously traveling first ground processing device and the autonomously traveling second ground processing device.
