I am just new to GIS and Python. I have a shapefile of a country and a file with 300 locations (latitude and longitude) from different parts of this country. I extract the NDVI (Landsat 8; band 3 and band 4) and ALAN (NOAA and DMSP) map by using the Google Earth Engine and now I want to extract the value of NDVI and ALAN for each location. I tried to do this by using the zonal statistics in QGIS app but couldn't. Can you suggest some simple material for training or explain how can I do this? The ones I found are a little complicated.

For your lon, lat points, use the Sample raster values tool, not Zonal Statistics.– user2856Commented Apr 1, 2022 at 6:06

Many thanks for your suggestion, it was great. now I have another question in terms of extracting NDVI value from QGIS. I know I should use Zonal statistics but when I want to calculate NDVI I don't have the band I need. I mean it doesn't appear in QGIS.– faryCommented Mar 29, 2022 at 5:41

Please post a new question with the data you are using and what exactly the problems are. Adding images showing other users would be helpful as well.– BinxCommented Mar 29, 2022 at 15:05
