<p>Metode <em>Split-Windows Algorithm</em> (SWA) memiliki metode yang bervariasi untuk pengolahan suhu permukaan (<em>Land Surface Temperature</em>/LST). Salah satunya pada pengolahan citra Landsat 8 OLI/TIRS (<em>The Operational Land Imager and the Thermal Infrared Scanner</em>) karena menggunakan dua saluran yaitu 10 (10,60 - 11,19 µm) dan band 11 (11,50 - 12,51 µm). Metode SWA pada penelitian ini menggunakan data primer yaitu parameter uap air untuk meningkatkan akurasi pengolahan suhu permukaan. Data parameter uap air diperoleh dari citra MODIS untuk mengetahui nilai rata–rata uap air (<em>W)</em> dan citra emisivitas diperoleh dari citra Landsat 8 OLI/TIRS dengan saluran tampak. Perolehan data tersebut dilakukan dengan bantuan Microsoft Excel, berbeda dengan penelitian sebelumnya yang menggunakan aplikasi MODTRAN (<em>MODerate resolution atmospheric TRANsmission</em>). Tujuan dari pengolahan suhu permukaan dengan metode SWA menggunakan data parameter uap air untuk mengetahui akurasi antara hasil pengolahan citra dengan nilai suhu permukaan di lapangan. Hasil pengolahan data suhu permukaan melalui metode SWA menunjukkan perbedaan nilai yang kecil (&lt;1°K) terhadap kondisi suhu di lapangan. Selain itu terdapat pola keselarasan antara penggunaan Microsoft Excel untuk perolehan data dengan aplikasi MODTRAN sehingga proses perolehan data parameter uap air telah sesuai. Aplikasi SPSS digunakan untuk mengetahui tingkat hubungan dan akurasi dari hasil pengolahan suhu permukaan metode SWA terhadap hasil survey lapangan dan menunjukkan nilai korelasi sebesar -0,962. Perolehan dan pengolahan data suhu permukaan dengan metode SWA akan optimal jika nilai <em>transmitted atmospheric</em> yang digunakan merupakan wilayah untuk daerah tropis.</p>

Satellite data in the thermal infrared range are a powerful source of information for the analysis and determination of city urban area temperature anomalies. The article presents a technique for monitoring the land surface temperature on the basis of combination of ?Landsat 8? satellite thermal infrared data with PlanetScope satellite constellation high resolution data. Such combination of satellite data from several spacecrafts increase the detalization of temperature maps to the level of individual city blocks. Determination of the nature and boundaries of temperature anomalies will help to understand the causes of the unfavorable environmental situation in Krasnoyarsk, where, in addition to high industrial emissions, their influence and atmospheric processes, leading to the fact that impurities are delayed and concentrated over the city. The results shows that the temperature in the places of thermal anomalies is 5?-8? higher than the average land surface temperature of the city. Based on the results of the analysis of summer thermal multi-temporal space images, several thermal zones of different nature were outlined on the territory under consideration. This information can be used in planning the development of the city, the design of new urban neighborhoods.

This paper illustrates a proposed method for the retrieval of land surface temperature (LST) from the two thermal bands of the LANDSAT-8 data. LANDSAT-8, the latest satellite from Landsat series, launched on 11 February 2013, using LANDSAT-8 Operational Line Imager and Thermal Infrared Sensor (OLI & TIRS) satellite data. LANDSAT-8 medium spatial resolution multispectral imagery presents particular interest in extracting land cover, because of the fine spectral resolution, the radiometric quantization of 12 bits. In this search a trial has been made to estimate LST over Al-Hashimiya district, south of Babylon province, middle of Iraq. Two dates images acquired on 2nd &18th of March 2018 to retrieve LST and compare them with ground truth data from infrared thermometer camera (all the measurements contacted with target by using type-k thermocouple) at the same time of images capture. The results showed that the rivers had a higher LST which is different to the other land cover types, of less than 3.47 C ◦, and the LST different for vegetation and residential area were less than 0.4 C ◦ with correlation coefficient of the two bands 10 and 11 Rbnad10= 0.70, Rband11 = 0.89 respectively, for the imaged acquired on the 2nd of march 2018 and Rband10= 0.70 and Rband11 = 0.72 on the 18th of march 2018. These results confirm that the proposed approach is effective for the retrieval of LST from the LANDSAT-8 Thermal bands, and the IR thermometer camera data which is an effective way to validate and improve the performance of LST retrieval. Generally the results show that the closer measurement taken from the scene center time, a better quality to classify the land cover. The purpose of this study is to assess the use of LANDSAT-8 data to specify temperature differences in land cover and compare the relationship between land surface temperature and land cover types.

Abstract This investigation was conducted for the estimation of the temporal land surface temperature value using thermal remote sensing of Landsat-8 (OLI) Data in Hawassa City Administration, Ethiopia. Satellite datasets of Landsat-7 (ETM+) for 22nd March 2002 and Landsat-8 (OLI) of 22nd March 2019 were taken for this study. Different algorisms were used to estimate the Normalized Difference Vegetation Index threshold from the Red and Near-Infrared band and the ground earth's surface emissivity esteem is legitimately recovered from the thermal infrared by coordinating with the outcome got from MODIS information. The land use land cover map of the city was prepared with better accuracy using the on-screen classification technique. The spatial distribution of surface temperature of the city range from 6.62°C to 22.54°C with a mean of 14.58°C and a standard deviation of 11.25 in the year of march 22nd 2002. The LST result derived from Landsat 8 for March 22nd, 2019, ranges from 11.97°C to 35.5°C with a mean of 23.735 °C and a standard deviation of 16.64. In both years the higher LST values correspond to built-up/settlement and bare/open lands of the city; whereas, lower LST values were observed in vegetation (trees/woodlot, shrubs, and grass forested) area. Urban expansion (built-up area roads, and another impervious surface), decline in vegetation levels due to deforestation and increasing population density. Increasing an evergreen tree and green space coverage, design and develop city parks and rehabilitate the existing degraded natural environments are among the recommended strategy to reduce the rate of LST.
