Géoportail 3D: new data available on line
Géoportail has added new data to improve your 3D browsing. This new data includes: names of communes and place-names, roads, points of particular interest in a given geographical zone etc.
To view this new data, activate the relevant layers in the layer catalogue.
You will find these layers in the following sections: Administrative units, Transport networks, Built-up areas and Altitude.
Communes ("Administrative units" section)
 |
This layer enables the names of communes to be displayed on top of the relief. Place the cursor over the name of the commune and a screen tip will appear with the INSEE number, the number of inhabitants and the department in which the commune is situated. |
Roads ("Transport networks" section)
 |
This layer enables A roads, motorways, B roads etc. to be displayed. Each type of road is in a different colour: mauve for motorways, red for A roads, orange for B roads, yellow for minor roads etc. Place the cursor over the road displayed and a screen tip will appear with its name and classification. |
Inhabited places ("Built-up areas" section)

This layer enables the names of inhabited places to be displayed on top of the relief. |
Oronyms ("Altitude" section)

Areas of activity ("Built areas" section)

This layer enables areas of activity to be displayed; each different type of activity is in a different colour: mauve for education, red for health, grey for trade and industry. |
New vectorial data and TerraExplorerThese new data sets are called "vectorial data": the display is calculated dynamically in real time, so as to ensure smoother, faster on-screen display. To use this type of data, just install (or update) TerraExplorer software. You will automatically access the software download page (if it is not already installed on your computer or needs updating) when you go to the Géoportail 3D viewing page. |
