An improved global calibration was derived and image enhancement techniques developed to increase the image quality, sensitivity, and spatial resolution of maps from the Infrared Astronomy Satellite (IRAS) survey data. These goals were achieved by augmenting and extending GEISHA (Groningen Exportable IRAS High-resolution Analysis) system. A completely new calibration scheme using the zodiacal light emission as a standard candle has been designed and implemented. This calibration is better suited for smaller spatial frequencies. Comparison of the zodiacal light calibration and that of IPAC (IRAS Processing and Analysis), for point sources, gives very satisfactory results (
