ECWP

Imagery in the Oregon Imagery Explorer also supports the ECWP protocol.

ER Mapper/Leica Geosystems has developed the ECWP protocol and describes it as "the fastest way of accessing large imagery datasets. The ECWP protocol transfers compressed blocks from the server to the client, providing realtime roam and zoom functionality on image updates. Many applications natively support ER Mapper’s streaming imagery protocol."

"ER Mapper/Leica Geosystems supplies free plug-ins for Internet Explorer and Netscape browsers as well as many major imaging packages to enable streaming ECWP access."
