Part 1 – Project Setup
The steps necessary to add a local geoid and custom Python scripts to MetaShape are described below.
In order to improve the horizontal and vertical accuracy of maps and 3-D models generated in Photoscan, it is sometimes necessary to apply a local geoid. Any geoids in the correct data format can be used or they can be downloaded from Agisoft here.
Once downloaded, they must be copied to the Agisoft geoids directory (e.g. C:\Program Files\Agisoft\MetaShape Pro\geoids) prior to launching the software. If MetaShape is running, after the geoid is copied, it must be restarted.
Python scripts are used to perform multiple sequential operations using a single command. They serve as shortcuts or give access to other functions of the software and data. The MetaShape Python script repository can be found here.
Click here to download a script used to adjust the altitude of input photos. This updates the altitude from heights relative to the WGS 84 ellipsoid to heights relative to the ground which are much more useful and relevant.
Any downloaded scripts must be copied into the MetaShape Scripts folder (e.g. C:\Program Files\Agisoft\MetaShape Pro\python\Scripts).
