Converting Data to GeoTIFF

1. Run the ASF Convert Tool.

2. Click the "Browse" button, and find the location of your .D files. You may use ctrl-click or shift-click to select multiple .D files to convert.

3. Click on the "Export" tab, and select "GeoTIFF" from the "Format" dropdown list.

   

   Figure 1. Selecting An Output Format

   The default export format is JPG. (That is why we didn't have to change it in the previous example.)

   Notice that when you select "GeoTIFF" the "Output Bytes" option becomes available. By default, GeoTIFFs are exported as floating-point data, since this is the most accurate. However, some GIS packages (in particular, ArcGIS) have trouble with GeoTIFF data in this format, so you may prefer to export the GeoTIFFs using a byte (0-255) format. You can do this by checking the "Output Bytes" box. (There are a couple different methods for scaling the floating-point data to byte, and you are allowed to select which you'd like. Normally there is no reason to choose anything other than Statistical 2 Sigma.)

   Exporting your GeoTIFF data as bytes instead of floating point will also result in substantially smaller files.

4. Click "Execute".

5. In this case, the "View Output" option is not available.
