A system and method for acquiring spatial mapping information of surface data points defining a region unable to receive effective GPS signals, such as the interior of a building, includes an IMU for dynamically determining geographical positions relative to at least one fixed reference point, a LIDAR or camera for determining range of the IMU to each surface data point, and a processor to determine position data for each surface data point relative to the at least one reference point. A digital camera obtains characteristic image data, including color data, of the surface data points, and the processor correlates the position data and image data for the surface data points to create an image of the region.
