Can height data captured by my GPS with a track be used to replace DEM data
for my map.
If height data is downloaded with the track then it will be used in the track display.
It cannot be used to replace the elevations shown from the DEM data.
My heights do not agree with the contour lines on my map
The units (metres /feet) may not be correct, check that the units selected in
OziExplorer are the same as the units the contour lines are drawn.
We have seen DEM data files with incorrect data, use the "Elevation Adjustment" in
OziExplorer / Elevation Configuration to adjust the data. (Don't forget to reset the
Elevation Adjustment back to zero).
My operating system is Windows 95
Windows 95 and Windows 95a users may download OpenGL Version 1.1 from Microsoft's
website. Download it and place the files in the Windows\System directory. It should fix
OpenGL problems with the Win95a Operating System.
DO NOT run this program unless you have the original edition of Windows 95 AND you are
specifically getting the error message that you are missing OpenGL32.DLL.
Windows 95 OpenGL Update or Download Windows 95 OpenGL Update from Microsoft
My map doesn't look smooth, it has ridges which should not be there
You have turned off filtering in Elevation Configuration in OziExplorer and then you
have "oversampled". In the 3D Map Control dialog in OziExplorer, the value of the
grid delta (metres per grid) is a lot less than the elevation data grid. Change the
grid size in pixels using the drop down box until the metres per grid value is about
equal or greater than the resolution of the elevation data.
It is taking a long time to create my 3D map
The number of vertices is too many for your computer system to process quickly.
Reduce the number of vertices by increasing the "metres per pixel" or select a
smaller area of the map. Older computer systems will have difficulty processing
more than approximately 10,000 vertices.
