Abstract

Spatial distance calculation is a basic and primary function of GIS, however due to the complication of the algorithm and the existence of rounding and truncation errors, it is very difficult to obtain the oracles of the implementation, so traditional testing methods face great challenges. Metamorphic testing can help solve the oracle problem by comparing the relations among multiple inputs and outputs. This paper tries to find out the error in spatial distance measuring of GIS using metamorphic testing. We choose a universal algorithm called the Great Circle Calculation, produce 5 metamorphic relations for it and then carry out the metamorphic testing. The experimental results show that metamorphic testing is effective in finding errors of spatial distance measuring.
