Open Header(.hdr) or DEM(.dem)

is used to open a FlyBy header file (.hdr) or Digital Elevation Model located on the local system. FlyBy currently reads only 1 Degree (1:250,000-scale) DEMs. FlyBy looks for the extension ".dem" to determine if a file is a DEM. This extension is not on files obtained from the USGS but must be added by the FlyBy user. DEMs are available from the USGS at either of:

• http://edcwww.cr.usgs.gov/glis/hyper/guide/1_dgr_demfig/index1m.html
• http://edcwww.cr.usgs.gov/glis/hyper/guide/1_dgr_dem
• http://edcwww.cr.usgs.gov/glis/hyper/guide/1_dgr_demfig/states.html

The Open Header dailog allows files to be selected from the local machine or from remote machines using FTP or HTTP.
