HoudahGeo structures the geocoding process into three successive steps:
|Load:||Start by adding images and optionally GPS track logs to the project|
|Process:||Add or update metadata for the images in the project|
|Output:||Export or publish the newly created metadata|
The HoudahGeo project window thus has three states. One for each step. Use the first three toolbar buttons to switch between states. The toolbar will update to show buttons applicable to the current context.
HoudahGeo works on project files that may be saved for later use. A project file is essentially a list of image files. A project stores metadata for the images it references. Additionally GPS track logs can be loaded into a project.
