I am working on VIIRS SDR dataset. I had different layer of Brightness temperature, latitude and longitude in given .HDF5 dataset. Using reference from http://geoinformaticstutorial.blogspot.in/2014/06/reading-and-map-projecting-amsr-2-data.html I had created different VRT files and warped it to give geolocation. I got raster of Brightness temperature as shown in uploaded image below. it is in .tif format. I am also attaching VRT files which I had created. https://drive.google.com/open?id=1t3gFJYl0SdysS2zEJxlRJsU0kD0CR0_J (Bright.vrt) , https://drive.google.com/open?id=1hbCyWGjqw4VwIJjk9d_bQKW1ElJ5ibxb (lat.vrt) and https://drive.google.com/open?id=1ni27bXVnQ0ejyHMmF47Hebba-FOFTP3x(lon.vrt) According to user guide of the dataset, lines appearing in the image should be removed after giving geolocation.

Kindly help me to figure out what can be wrong with it?enter image description here

  • Did you just copy the EPSG codes from the link you posted? If so, you may be using a projection that is not suitable for your location. It would help if you would post your code (and in this case also the output of gdalinfo on your tif). Also, it is pointless to share .vrt files as they only point to the location of data on your local disk (i.e. to your tiffs). – Jon Nov 7 '17 at 23:32
  • I had not copied the exact code from given link. I just warped VRTs without specifying projection system because it was mentioned in VRTs it self. Projection of all the layers is "WGS84" as mentioned in metadata. I am posting gdalinfo of .tif file before as you had asked. – vigna purohit Nov 8 '17 at 7:26

  • WGS84 is not a projection, it is a Geographic Coordinate System. You should try projecting your vrt to see if that doesn't improve the display--from your coordinates, it looks like you can use the same EPSG as in the tutorial (3411). The types of display issues you're having are similar to those I have when my data is in a different CRS than my display map. – Jon Nov 8 '17 at 14:57
  • Thank you for the suggestion.I had tried to project it with different EPSG but it is giving the same result. Please help me with something else if it can solve the issue. @Jon – vigna purohit Nov 9 '17 at 4:07
