Member Function Documentation

checkLongitude()

void ossimRpfUtil::checkLongitude ( ossimGpt &  left, ossimGpt &  right  ) const

private

Method to test for 360 spread, 180.0 <–> 180.00 and set leftLon to -180 if both left and right are 180.0 degrees.

This adds a small tolerance to the test.

Parameters

left	Left hand side of scene. This is the value that will be flipped to -180 if test is true.
right	Right hand side of scene.

Definition at line 309 of file ossimRpfUtil.cpp.

References ossim::almostEqual(), and ossimGpt::lon.

   // Test for scene coordinates being 180 to 180 (360 degree spread) and
   // adjust leftLon to -180 if so.

   // NOTE:
   // Setting tolerance to 1/7200 about 15 meters.
   // Not sure if this is too loose or not. (drb)

getDotRfpFilenameForEntry()

void ossimRpfUtil::getDotRfpFilenameForEntry ( const ossimFilename &  outputDir, ossim_uint32  entry, ossimFilename &  outFile  ) const
