Daftar Isi:
- Rapidly growing urban areas will increase the burden of the area to support environmental quality. Through the measurement of land surface temperature distribution as the physical parameters of the environment and land cover characteristics, this research was done as the development base in Yogyakarta urban area. Distribution of land surface temperature measurement with emissivity normalization method and spatial analysis of the standard distance (SSD) were used in this study. Surface temperature derived from TIR sensor on ASTER imaging satellite (channel 14) and land cover characteristics derived from SSD analysis through the hot spot object processing by GIS. The result showed that the minimum land surface temperature was 25 °C and the maximum was 35 °C, with the highest heat concentration is in the urban center and decreasing in the peri urban areas. Acquired seven types of land cover in the study area, these are water bodies, buildings roof, moor, paddy field, open land, asphalt, and mixed vegetation. The land cover pattern following the land surface temperature distribustion. Non-vegetated land cover has high temperature, 30°C - 31°C, relative humidity between 45 %- 47 %, and wind speed is between 6 � 9 km/hours. Vegetated land cover has lower temperature, 28°C - 29°C, retive humidity is between 53 % - 55 %, and wind speed is between 10 � 11 km/hours. Physical information such as temperature, humidity, and wind speed has not been the subject of research in planning policy, so that giving implication in land cover pattern which can not reduce urban heat.
