Thank you. This is important to me. I am undergraduate student. Nowadays i am carrying research about Feature extraction using Landsat images. In this case previous researchers were done surface reflectance procedure within two steps. First step, DN value convert to the Radiance value after the Radianace value convert to reflectance value. I have problem now, can i get same result using this method? other one Can this method apply for landsat 5 images?......
Hi Dulan .... Well this formula is applicable to Landsat 8 only ..... You can check the below mentioned link for Landsat 5 & 7 www.gisagmaps.com/landsat-5-7-conversion-to-sr/
@@geotechnocrats394 Thank you. I will Check. Dr.Shivangi, Can you make a video about how to use Digital Shoreline Analysis system?(This is suggest from me).Becuase of in the youtube there are lack of infomation about these field.Keep it up and good luck doctor.
good explantion but it still not ground refapntace like there is no correction for earth sun distance and also there is no subtraction of values reflected from cloud after both of these parameters these image can be considered as ground relfactance
respected mam, i am doing my Btech final year project on " image transformation to study the spectral index for monitoring air pollution". I read your research paper on air pollution. i have calculated TOA and downloaded surface reflectance from espa.. please guide me . what should be the next step..
Madam, thank you very much… your explanation is very easy. as I am a student of M.tech I will need more help from you.....please keep in touch with the help of comment box... Thank you
Simple yet informative
Thank you ma'am 😇
Thank you so much mam

can you make a tutorial of dn conversion using planet imagery?
How to convert dn value to haze value ?
How can I calculate this for band 10 and band 11? Please if someone know, do reply meeee

Calculate Atmospheric Reflectance by substracting the Surface reflectance Image by TOA image (AR = TOA - SR)
