Hi Ashish, re: > Here is the sample data: > https://lpdaac.usgs.gov/products/modis_products_table/myd11a1 > I downloaded from: http://earthexplorer.usgs.gov > > Screenshot shows the spatial extent and the location of source: OK, thanks for attaching a sample data file. I was able to open and display information from the file sent MYD11A1.A2013227.h11v04.005.2013228223748.hdf in the IDV with no problems. I did this as follows: - copy the HDF file to a directory that is accessible to the IDV - open the IDV (I tried v5.0 and v4.1 to make sure) and navigate the UI to the file: Dashboard -> Data Choosers -> General -> Files Find the file on the local file system and select it. - set the Data Source Type to 'Grid Files (netCDF/GRIB/OPeNDAP/GEMPAK) - click on Add Source - open the 2D grid in Fields and open MODIS_Grid_Daily_1km_LSTData_Fields - select the field that you want to display and then choose how you want to display it I chose 'Time of daytime Land-Surface Temperature Observation' and then displayed it with a color shaded plan view Comment: - the data in the file is _not_ an image; it is a gridded field created by compositing more than one MODIS band Can you try the procedure above and let us know if you have any problems?
