The weather is one of the main factors for events that happen on the surface of the earth. Surprisingly, no effort was made to use weather features together with satellite images for land cover classiffication. In the paper, we use temperature data along with satellite images to improve the accuracy of the classiffication and to get classiffication as early in the year as possible. Every year has different conditions, so the temperature can be used as an objective criterion at what time to do classiffication.
