thanks Andrew,

When we get back to work, I'll load the PRJ into the ESRI suite.?ÿ With 9002 as the EPSG code, and lacking a DATUM tag, ESRI won't kick it out, but throw the file into "custom", which will force the end user to define projection.?ÿ This is getting pretty darn common in SfM software - putting the ONUS of metadata on the end user.?ÿ Not my cup of tea, but this will make for a good story next month.?ÿ Thanks.

?ÿ

Joel,?ÿ

Esri software is going to fail that prj string because we don't support LOCAL_CS nor LOCAL_DATUM.

Hi Lee,

Have you encountered any issues with manually entering the geoid seperation? I have a large project that was flown with an eBee RTK utilizing a base station, and I'm having issues with the vertical conversion in Pix4D.

Thanks,

Greg

Be sure to enter the correct?ÿunits and direction when you apply the manual GEIOD correction.

Input Coordinates enter is Meters and positive GEOID.

Out Coordinates enter USft and positive?ÿGEOID.

Hi Greg,

You have to use the advanced options under the output coordinate system and set?ÿthe geoid offset. Where I am located the offset is a negative number.
