Data visualization is based upon an embedded Google Maps application. It provides all basic Google Maps functionality. By default the map will show the earth with dots indicating study reference locations. These dots are colored based on the users’ access permissions for each study: gray indicates that only the study name and summary information are visible to the public; light green indicates that one or more animal tracks can also be viewed; and dark green indicates that all of the animal tracks can be viewed. This same color scheme is used for the boxes next to each study in the study list. Note that if a user does not have permission to view a study name and summary, the study will not show up in the map or on the list.

When you select a study from the list, the reference location will be highlighted in pink and all measured locations along the study tracks will show as small pink points on the map. If you highlight one or more deployments within a study, these will be shown in blue, with lines between these points with arrows indicating the track and direction. The starting point of a track is shown with a red cross, the ending point with a green cross. In addition to the standard Google Maps zoom functions, you can select the zoom icon on the result grid to zoom to the bounding box of the selected study or deployment.

In addition to these default views, you may toggle between several visualization modes by selecting Options from the menu.

See below for more details on how to

Draw study markers

This option displays all study reference locations (selected by default).

Draw lines for selected animals

This option connects all data points of the selected tracks with gray lines and arrows indicating the direction of movement.

Draw lines for highlighted animals

This option connects all data points of highlighted tracks with lines and arrows indicating the direction of movement (selected by default).

Draw density

This option draws the density distribution of either data points or deployments (~= animals). It considers all data sets on the map, irrespective of whether they are selected or not. However, data points of animals that are not selected disappear. If you have one data set with a high sampling rate and another with a low sampling rate, then the point density of the combined data sets will be strongly biased towards data set 1, whereas the deployment density might make more sense.

Point size

This option allows you to change the size of location points (Small is selected by default).

Color schema

This option allows you to change the line color of selected tracks (Pink/Blue is selected by default).

More options

Use the rectangle selector tool  to select individual tracks from multiple studies. With your studies of interest visible on the map, click on this tool and use your mouse to draw a rectangle around the area of interest. All tracks that intersect with the selected area will be highlighted on the map and in the Result Grid.

Use the rectangle zoom tool  to zoom into an area on the map. Click on the icon and use your mouse to draw a frame around the area you want to see. The map will zoom in to display this area.

Use the link tool  to create a URL that you can cut and paste elsewhere. Following the link will load the same map view and tracks that are visible when you click the icon.
