I am new in the field and I would like to ask which is the correct way to define a point location for an image with EPSG 4326 crs.
I used QGIS software, and created a .csv file with the latitude - longitude information in decimal degrees (I was given the information of those coordinates both in Degrees - Minutes - Seconds, and decimal degrees. I checked these from Google Maps to see if they represent my locations of interest.) I added this .csv file I created as "delimited text layer" in QGIS to define the points in QGIS. And I used these points to extract remote sensing data from the image.
My question is; is defining the points in decimal degrees is correct for EPSG 4326 crs images?
