Remote sensing techniques for producing land use maps

Monitoring of land use changes in Lahijan County is the purpose of this study. In this study, land use maps produced by +ETM and OLI Landsat sensor images by Maximum Likelihood method in 2002 and 2015, has been classified in four classes: water, forest, agriculture and human made, with a kappa coefficient of 0.87 and 0.92 percent, as well as a total accuracy of 89.73 in 2002 and 93.68 in 2015. Then, the changes of land use maps were monitored using Change detection method. The results of this monitoring showed the urban use class had the highest increase with 4437.16 hectares, and in contrast, the forest class had decreased by 3347.48 hectares which is largely due to the construction of tourism in the second homes and catering centers in the city of Lahijan.
