Hi Greg, > > I would like to display a Level III McIDAS Area file in IDV. It loads OK but > the display is black. Any thoughts? > There is actually data there but the range of the data is ~0-6 and that is only in a small part of the image. The rest is 0. With the default color table range of 0-255 you are getting mostly black (using the gray scale color table). Try changing the Color range - right click on the color bar and select "Change Range" You can also add a data probe or a data transect on this image to see the actual values. Don is out for a few days but I'll ask him to look at this file to see if there is anything wrong about the data or our reading of the data. -Jeff Ticket Details =================== Ticket ID: HJT-379438 Department: Support IDV Priority: Normal Status: Open
