To reveal the influence of artificial buildings on observed data effectively, it is of importance to identify the ratio of the building area around a meteorological station. The software was developed in order to identify the building area based on the obtained satellite remote sensing images. The proposed software is developed in the Windows system and can provide reliable data analysis for meteorological researches. Hundreds of satellite remote sensing images are experimented using the proposed software. The results indicate that the proposed software achieves higher precision, reliability and efficiency compared with the manual statistical methods.
