Abstract
Seven 11.6' x 11.6' fields along the inner Galactic plane were imaged by th e Infrared Space Observatory's ISO-CAM camera to investigate the large scal e properties of the Galaxy. We present results from this GPSURVEY program a t wavelengths of 10 and 15 mu m as well as some complementary observations from the ISOGAL project at 7 mu m. Point source detection is complete to a limiting flux of about 10 mJy. There is generally good agreement between th e observed source counts and that predicted by the SKY 5 multiwavelength Ga lactic structure model. However, some discrepancies were found at certain G alactic longitudes, particularly near the Galactic center. Indications of t he nature of the excess sources are inferred from the colour histograms.
