Thank you for the tutorials. They are extremely helpful. I wanted to ask a question regarding calculation of UHI and UTFVI values using LANDSAT. While calculating the mean UHI for a city, I got a very small value (9.2 * e-12) and negative UTFVI value and that was because of some of the points having LST values lower that the mean LST. So, if i want to calculate the intensity of UHI in the city, should i omit the negative UHI values to get the mean UHI? thank you

Hi, you can add a constant to remove negative values.

In case you need temperature monitoring over urban area, ui.chart.image.series must be used.

@@amirhosseinahrarigee برای soil texture باید از متد .eq() استفاده کنم ،تفاوتش مثلا (phخاک) این هست که برای هر ۶عمق یه dictionary یا class Table به نام Value = [1:12] , Color=[red,blue, black...] Description =[CL,SO,LO, ...] تعریف کنم‌ .من فقط تونستم روی نقشه خروجی بگیرم نتونستم خروجی عددی برای هر عمق بگیرم . امیدوارم موفق پیروز باشید 🙏
