How can I assess the display speed of the various file formats within GeoView?
Simply download Geographic Transformer and run it in evaluation mode. Most Blue Marble applications allow for FREE display of most raster and vector formats. The Geographic Transformer is the one application that allows you to display DXF/DWG, DGN, MIF, TAB, VPF and ESRI Shape as an overlay to raster files such as TIFF, BMP, JPG, ADRG and NOAA (BSB) electronic charts.
