With the map controls: You have a pan and zoom control on the top left of the map. It allows you to zoom in and out, and to pan the map.
With the mouse: you can zoom in and out using the mouse wheel. To pan the map, just left click on the map, stay pressed, and move the mouse.
Using the keyboard: the jeys + and - allow to zoom in and out, and the arrows to pan the map.
Advanced zoom: you can determine the sector on which you want to zoom : press the "shift" key, left click, hold it pressed, and move the mouse to draw a rectangle. The zoom will be set corresponding to the drawn area.
Notice that you have also available some shortcuts in the lateral panel.
On the top of the map, a toolbar reproduces those navigation controls: zoom max, zoom in/out, pan. Other tools are also available:
On the right is a lateral panelYou can fold/unfold the panel using the arrow next to the title of the block
The first block allows you to change the language.
The second one allows to switch between the 2D (default) and 3D (virtual globe) modes. Before switching to the 3D mode, we advise you to read the dedicated paragraph (see lower)
The "Layers" panel allows you to choose which layers are displayed in the map.
Each layer require bandwidth. Indeed, if you connexion is a bit slow, we advise you to limit the number of layers checked at the same time
You can perform various operations on the layers : you can reorganize them by drag'n'drop.
right clicking on a layer displays a contextual menu. It allows to to change its transparency, remove it or zoom to its max bounds.
the legend is linked with the layers panel : if a legend is available for the selected layer, it will be displayed here
The place finder allows you to search for a place (city, common place). It uses the geonames database. The search is dynamic : a drop-down list of choices is updated as you enter the name of the place.
The shortcuts allow you to position youself quickly, either on predefined views, or on given scales.
Enfin, the mini-map gives you the current position on the world, and le last panel gives the mouse position and the current scale.
The virtual globe requires some pre-requisites. that's why you should read this first.
The virtual globe is a java applet, based on the open source virtual globe WorldWind. For itto work properly, you shall have a java version at least equal to 1.5.07 running on your computer, and a reasonnably recent graphics card
during the applet startup, you will be asked to allow the applet execution : you must accept, as the applet needs it to store the cache data on your computer
Moving in the virtual globe is quite the same as in 2D, except you can also incline and rotate the view. You just have to right-click and move simultaneously the mouse
Last but not least, you have an additionnal option : adding WMS (Web map service) layers, using the top left "WMS" button. Two servers are preconfigured, and you can add some more clicking on the "+" tab
