imagerie obsolète et ancienne

<\/HEAD>

pourquoi les images satellites sont-elles si anciennes ? Existe-t-il un service qui peut fournir des clichés d'une zone tous les 2-3 jours ?<\/P>

De plus, comment savoir quand l'image vue sur esri a été prise ? elle semble assez ancienne cependant.<\/P><\/BODY><\/HTML>

Image date: simply use the info tool on the image to get the date information. Be aware that different tiles may have different dates.

For imagery that is taken on a frequent basis, you would probably need to look into sattelite imagery, and I do not know if the resolution would meet your needs.

If you need infrequent images, terraserver may meet your needs, although you will need to pay a nominal fee to search and view imagery, and a fee to acquire it.
