Part 1 – Project Setup

Chapter 1.1 – Geoids & Python Scripts

Overview

The steps necessary to add a local geoid and custom Python scripts to Photoscan are described below.

Geoids

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\PhotoScan Pro\geoids) prior to launching the software. If Agisoft is running before the geoid is copied, it must be restarted.

Python Scripts

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 Agisoft Python script repository can be found here.

Any downloaded scripts must be copied into the Agisoft Scrpits folder (e.g. C:\Program Files\Agisoft\PhotoScan Pro\python\Scripts).
