PCIDISK, Silicon Graphics Alias / Wavefront  data in .pix files.  PIX files, like ESRI BIL, can contain multiple channels, which can represent photography imagery or other raster data, such as terrain elevations.  PIX files can also contain vector layers.  PIX format files intended for GIS use will often provide coordinate system information, so images may import with coordinate system automatically assigned.  



To import from PIX format:


  1. Choose File-Import from the main menu.

  2. In the Import dialog browse to the folder containing data of interest.

  3. Double-click the file ending in .pix for the data of interest.

  4. One or more images and tables will be created.



In this case, the PIX file imports as many images and tables.  


We can double-click on images that are created to view them.   For a more interesting display, we first create a new data source using a Bing street maps image server as shown in the Example: An Imageserver Tutorial topic.   We then create a map and drag and drop the Bing layer into the map, and then we drag and drop the image into the map.



It appears to show radar data for a region in Canada.  It has been imported with full coordinate system information.


We have used Style in the image above to assign a palette to the single channel used in the image.  The palette uses a transparent color for the color used in the "collar" of the image so that only data appears in the layer.  For an example of the technique, see the GRD, Northwood .GRC, .GRD  topic.





Another example, shown above, shows the irvine.pix file imported into Manifold, creating two drawing layers and also a variety of images.  All have correct coordinate system information provided.
