画像が古くて時代遅れです

Question

<\/HEAD>なぜ衛星画像はこんなに古いのですか。2〜3日ごとにある地域のスナップを提供できるサービスはありますか？<\/P> また、esriで表示されている画像がいつ撮影されたかはどうやってわかりますか？かなり古いように見えます。<\/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.
