Résumé
A virtual landscape is a tool that is intended to help geo-scientists, cartographers, engineers, hydrologists, and decision makers to better understand the environment with which they interact. Visualisation in 2D or 3D involves the display of data for human interpretation. Since most humans are able to see in three dimensions, a three dimensional (3D) representation of reality may improve our ability to interpret two-dimensional (2D) imagery and plans ; viewing images in 3-dimensional perspective may also contribute to increased understanding of features and their relationship within data sets, (Toutin 2001). Three-dimensional representation can offer insights that would not be readily perceptible from a 2D image of the same data. For example, instead of imagining the presence of a mountain from the structure of contour lines, the viewer can really see the mountain, its shape, and its perspective from different directions. In this study remotely-sensed data has been investigated as the main source of information for the generation of a digital virtual landscape of Al-Madinah Al-Munawwarah city in Saudi Arabia, in an attempt to establish whether the use of remotely-sensed data is able to afford a plausible and convincing view of the city and its environment. Al-Madinah Al-Munawwarah is the second of Islam’s cities, after Makkah Al-Mukarramah. Al-Madinah Al-Munawwarah has a long and important history and also holds a distinguished place in the hearts of all Muslims. At the heart of the city is the second of the two Holy Mosques, The Prophet’s Mosque, and the final resting place of the Messenger of Allah. Three-dimensional Digital Terrain Models (DTM’s) have been created from Digital Topographic Maps (DTopMaps) at scale 1:1000. Data fusion has been applied to provide colour information to the overlay data in order to enhance the appearance of the landscape. 3-dimensional scene attributes such as buildings, mosques, and trees have been created and inserted onto the landscape. Appropriate textures obtained from fieldwork have been applied to each object. A digital virtual landscape has been produced that is available on CD or on the Internet. This virtual landscape is potentially available to all Muslims and non-Muslims around the world who may wish to visit Al-Madinah Al-Munwwarah but are prevented from doing so by logistical constraints
