Python and Java API / Split in Chunks Script Quality and Filtering Settings

« on: November 15, 2017, 02:23:10 PM »

I have been trying out the "Split in Chunks" python script and it works well. However, it does not seem to give me the option to set the Quality and Filtering settings (my last run came out as High Quality with Aggressive Filtering). How can I set the Quality and Filtering settings to be what I want? Thanks

General / Re: Working with Elevations instead of Ellipsoid Heights

OK, I have made a stab at creating a custom PRJ file to get it to work.

Here is what I created:

COMPD_CS["NAD83(HARN) / Florida East (ftUS) + NAVD88 height",
PROJCS["NAD83(HARN) / Florida East (ftUS)",
GEOGCS["NAD83(HARN)",
DATUM["NAD83(HARN)",
SPHEROID["GRS 1980",6378137,298.257222101,AUTHORITY["EPSG","7019"]],
TOWGS84[0,0,0,0,0,0,0],AUTHORITY["EPSG","6152"]],
PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],
UNIT["degree",0.01745329251994328,AUTHORITY["EPSG","9102"]],
AUTHORITY["EPSG","4152"]],
PROJECTION["Transverse_Mercator",AUTHORITY["EPSG","9807"]],
PARAMETER["latitude_of_origin",24.33333333333333],
PARAMETER["central_meridian",-81],
PARAMETER["scale_factor",0.999941177],
PARAMETER["false_easting",656166.667],
PARAMETER["false_northing",0],
UNIT["US survey foot",0.3048006096012192,AUTHORITY["EPSG","9003"]],
AUTHORITY["EPSG","2881"]],
VERT_CS["navd88-12b geoid height",
VERT_DATUM["North American Vertical Datum 1988",2005,AUTHORITY["EPSG","5103"]],
UNIT["metre",1,AUTHORITY["EPSG","9001"]],AUTHORITY["EPSG","5703"]],
]

However, the program keeps giving me an error message stating "Unsupported Vertical Datum". Even the stock NAD(HARN) + NAVD88 Height that comes with AgiSoft Photoscan gives me the same message. I have all of the NAVD88 geoids downloaded into the geoids folder. I'm not sure what I am missing here. Any help is appreciated. Thanks,

General / Working with Elevations instead of Ellipsoid Heights

« on: March 22, 2017, 03:26:47 PM »

I am working on my first project with Photoscan Pro. I can see that I can change the horizontal datum and grid projection easy enough for the camera and marker positions (I'm working on NAD83(2011) datum with the Florida State Plane Coordinate System, East Zone in US feet). However, it appears that the program wants to use ellipsoid heights instead of the NAVD88 elevations that we typically work. I have downloaded the GEOID12B model to the geoid folder, but don't see how to tell the program to apply it. Can you help?

Thanks,
