imagens desatualizadas e antigas

por que as imagens de satélite são tão antigas? Existe um serviço que pode fornecer fotos de uma área a cada 2-3 dias?

Além disso, como posso saber quando a imagem vista no esri foi tirada? Parece bastante antiga, no entanto.

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.
