Using NAD 1983 StatePlane Louisiana South FIPS 1702 (US Feet), NAVD 88. The file is not returning accurate Z values. I have double checked my antenna height and geoid separation. Any suggestions on how to get an accurate Z value?</SPAN></BODY></HTML> Tue, 09 Jul 2013 21:04:44 GMT https://community.esri.com/t5/arcpad-questions/arcpad-10-on-ashtech-mobile-mapper-10/m-p/93036#M714 MartinMajnerick 2013-07-09T21:04:44Z Re: ArcPad 10 on Ashtech Mobile Mapper 10 https://community.esri.com/t5/arcpad-questions/arcpad-10-on-ashtech-mobile-mapper-10/m-p/93037#M715 <HTML><HEAD></HEAD><BODY><SPAN>The horizontal accuracy of the MM10 is 1-2 meters, so the vertical accuracy will be roughly 2-4 meters.

I take two shot not even 50' apart and they have a difference in z value of +/- 40 which is incorrect. I have double checked my geoid height and antenna height as well.</SPAN></BODY></HTML> Fri, 12 Jul 2013 11:38:18 GMT https://community.esri.com/t5/arcpad-questions/arcpad-10-on-ashtech-mobile-mapper-10/m-p/93038#M716 MartinMajnerick 2013-07-12T11:38:18Z
