未知题型 Please translate this passage into Chinese： Spatial resolution is a measure of the smallest object that can be resolved by the sensor, or the area on the ground represented by each pixel. The finer the resolution, the lower the number. For instance, a spatial resolution of 79 meters is coarser than a spatial resolution of 10 meters. The terms large-scale imagery and small-scale imagery often refer to spatial resolution. Scale is the ratio of distance on a map as related to the true distance on the ground. Large-scale in remote sensing refers to imagery in which each pixel represents a small area on the ground, such as SPOT data, with a spatial resolution of 10 m or 20 m. Small scale refers to imagery in which each pixel represents a large area on the ground, such as Advanced Very High Resolution Radiometer (AVHRR) data, with a spatial resolution of 1.1 km. This terminology is derived from the fraction used to represent the scale of the map, such as 1:50,000. Small-scale imagery is represented by a small fraction (one over a very large number). Large-scale imagery is represented by a larger fraction (one over a smaller number). Generally, anything smaller than 1:250,000 is considered small-scale imagery.
