# Geocode manually

The second, "yellow", step of geocoding consists of providing HoudahGeo with information on where the pictures were taken.

## Using the built-in map

Click the third button in the yellow tab of the toolbar. You are presented with a map view.
You may drag and zoom the map in order to place the marker at the location where the photo was taken. Apply coordinates to the selected images by clicking the “Geocode” button. Depending on your settings, HoudahGeo will automatically proceed to the next.
Using the arrow buttons, you may proceed to the next or previous images. The “Jump to Selection” button moves the map view to the coordinates of the currently selected image.
The button in the lower left corner gives access to bookmark management. Bookmarks will also be available for offline use from the Inspector panel.

## Using Google Earth

In absence of a GPS track log, the most convenient method for geocoding involves Google Earth.
Click the "Earth" button in the yellow tab of the toolbar. A floating window showing the currently selected image will open.
Wait for Google Earth to launch. Once Google Earth is ready, the floating window will track the coordinates Google Earth is currently looking at. Once you have navigated to the desired location, you need to click the "Geocode" button of the floating window to attach the coordinates to your current HoudahGeo selection.
Using the arrow buttons, you may proceed to the next image without returning to HoudahGeo.

## Entering coordinates manually

You may also enter latitude, longitude and optionally altitude manually. This is done directly in the table view of the main window.
Latitude and longitude are displayed using decimal degrees. Altitude is expressed in meters above sea level. You may however enter values using other formats. HoudahGeo will recognise and convert those values. E.g. you might enter "31°15"12'" or "12° 14.35" or "535 ft"
Latitude values that are south of the equator are negative. Longitude values that are west of Greenwich England are negative. Consequently locations in South America have both a negative latitude and negative longitude.
