I'm not sure if this behavior is expected or I am missing something.<br><br>I have a 1 band raster dataset (an elevation DEM) in TIF format. It has statistics computed from "gdalinfo -stats mydata.tif" However, when I open it in QGIS (both 1.6 and 1.7 trunk), and look at the Metadata tab in Layer properties, there are two sections that contain band stats information. The first section is labeled "Band 1" and lists the same stats as found using gdalinfo. The second section is labeled "Band" and says "No stats collected yet" for band 1. QGIS has to create the stats when I apply a color map or stretch. For large rasters, this takes a while, and must be done each time it's used in QGIS.<br>
<br>Has anyone experienced this behavior? Is this expected? Is there a way to let gdal compute all the stats that QGIS needs? Thanks.<br><br>- John<br><br clear="all">**************************************************<br>
