In this paper,a web-based system of remote sensing information extraction was developed by combinating IDL and ASP.NET technique. The IDL language calling the ENVI secondary development library realize the extraction of RS information. The data transmission mechanism between the C# and IDL was analysed with several program examples. The visualization of RS data and the extraction of RS information were realized in this way. Meanwhile,the RS data and the extraction information can be downloaded from the system.

Key words:   IDL      ASP.NET      Web      RS information extractio
