Thank you so much sir for this valuable sessional. This helped a lot in my thesis work. From KUET , Bangladesh.
Informative and valuable session 🙏🙏🙏
I like your enthusiasm!! Very informative sir
Great lecture sir... I learnt more new knowledge from you
Great sir and new learnt knowledge🙏🙏🙏
I would say the best teacher on TH-cam and very informative workshop haven't found any video like this. Great contribution sir.
Thank you so much.
@@DrJayantaDas Sir can you please provide the MMK codes for R??
Hello Dr Jayanta Das. I must say very excellently you have done it. And i believe you must be an ideal teacher as well. I have a small question, In start of your lecture you told that for trend analysis minimum data must be 30 to 35 years, what if we have min data of 20 to 25 years. Your comments plesase.
Please make a video on Identification of potential sites for water harvesting by Arc gis Using MCDM techniques
Sir,
Thank you for your insightful presentation. I have a small query regarding the ITA figures. According to the methodology explained by Zakei Sen, the ITA graphs should ideally be in a square shape to properly display the 45° angle. However, the graphs in your presentation appear to be rectangular, which makes it a bit difficult for me to interpret them correctly.
Could you please clarify this aspect for me? I appreciate your understanding and assistance.
Best regards,
Sir if you make a class over discrete transform wavelet then it will be very great ful.
Waiting proff.
I'm watching this video on data analysis for first time. Great video sir. I too want to publish paper on spatial temporal analysis. Could you please upload the analysis of temperature data too. It would be helpful for me sir.
Hello, does anyone know how to export both the man kendall and sen results from r ?
Sir can you tell me how to do season analysis mk test for monsoon season, kharif season, rabi season, winter season , may i know how to split data and proceed for mk test, as far now i could able to do annual basis but was unable to read data according to season and perform mk test, so please guide me how to do it sir?
Very helpful video for beginners. Thank You so much. Sir, could you please provide the R codes for MK/MMK test??
thank you sir for valuable information. I have a question is it Mann Kendall test good for temperature trends also or this test only for rainfall

Dear Professor,
I am currently in the process of writing a manuscript that involves analyzing the variability of precipitation, temperatures, and relative humidity in certain regions of Somalia. Regrettably, due to the civil unrest that has persisted for over two decades, there is a lack of ground-based data or station data available. In light of this limitation, I am considering the use of satellite data, such as NASA POWER data. Would it be acceptable to utilize satellite data for this study?
Thank you for the lecture
@DrJayantaDas Sir please provide that code for MMK in R software
Sir, can you please give me the codes
sir tell me how to prepare that map in arcmap...(significant increasing, decreasing) ????

@@DrJayantaDas SIR CAN I GET SOME DISCOUNT FOR THIS COURSE...THIS COURSE IS MUCH NEEDED FOR ME
@@chetanpandit747 It's only 999 for lifetime access
@@DrJayantaDas sir one doubt...u prepare map of premonsoon season in arcmap for significant trend non significant increasing trend like that...u use symbology tool or idw technique ????
Sir please tell me how to solve significant level of ITA determine by PDF using the formula of CL.
