Remote sensing in Iowa agriculture

The author has identified the following significant results. Photo-interpretive methods have been used for vegetation identification to include additive false color analysis using the I2S Miniadcol system. Enlarged black and white ERTS-1 imagery provides excellent synoptic coverage over large areas and this provides the vegetation type interpretor with a first tool. Analysis of field type using MSS bands individually gives the interpretor only shades of gray to base his decision. Combining the MSS bands and adding color through the I2S Miniadcol system provides the interpretor a greater degree of freedom in his decision making process. The information potentially available from ERTS-1 can be of great use in state planning and as an aid to the present crop survey programs.
