    Some experimental studies on the classification accuracy of urban structures were conducted using local density average (LDA) and local dentity variation (LDV) as the combined features of spectral and spatial information which replace conventional pixel-wise spectral information, for the purpose of verifying new possibility of data analysis by high resolution satellite data such as Landsat/TM and Spot/HRV. Airborne MSS data were used for simulating pseudo-satellite data of various ground resolutions from 5 meters to 80 meters. By the airborne MSS simulation experiment, the feature LDA or LDA combined with LDV was verified to give higher classification accuracy then the pixel-wise spectral feature, if ground resolution is higher than 30 meters. In addition, the resolution of 20 meters or 30 meters was proved to result in the highest accuracy with the feature LDA combined with LDV. By the experiment using actual satellite data, Landsat/TM and MSS data resulted in the reasonable accuracy which was predicted from the airborne MSS simulation. However, Spot/HRV data showed lower accuracy about 20 percent than the airborne MSS simulation accuracy, which is considered to be due to the spectral variation caused by offnadir observation from satellite. These experiments suggest new data utilization for urban analysis with high resolution TM or HRV data.

    This paper reviews the bundle adjustments in non-topographic photogrammetry using non-metric cameras. Unlike the bundle adjustments using metric cameras, many factors that should be considered increase, i.e., dependency or independency of unknown parameters, possibility of their direct observation, camera performances and exposure configurations, etc., because these factors influence both accuracy and stability in evaluation of object space coordinates. These factors are detailed in relation to stability of the least squanes solutions.
    On account of the large volume of the paper, part (I) only describes how to set up observation equations, followed by the treatment of additional parameters, least squares solutions and resulting strength of the network configuration of photogrammetry and conventional surveying, etc.
