I have downloaded satellite imagery from GLCF website, it has downloaded with .L1G file extension, I am not able to open this file in ArcGIS as well in Erdas, so please let me know how to open this.
Here are the steps on how to do it in ArcGIS (Extract from online help)
- In ArcMap, click the Add Data button. Navigate to the location of the HDF file. Click the file and click Add.
- The Subdataset Selection dialog box opens. Click a single subdataset to add. Optionally, press and hold the CTRL key to select more than one.
- If you choose more than one item, you can optionally check Add as RGB layer to add them as a single raster dataset layer.
- Optionally, check the Do Not Ask Again check box if you do not want the dialog box to appear again. Choosing this option automatically loads the first subdataset for any HDF and all the subdatasets for any NITF that you add.
- Click OK
