    A raw manuscript directly plotted by stereo plotter contains many mistakes and failures which should be edited and compiled manually. In the case of contour lines, editing process takes long time and needs high skills.
    Now analytical plotters and analogue plotters equipped with digital encoders became available and thus digital contour line data can be obtained, and an automatic method to compile digital contour lines has been studied.
    Compilation of contour lines is a kind of smoothing of the surface plane expressed by contour lines. Therefore, simple curved surface (named Local DTM, DTM=digital terrain model) is calculated to represent the local terrain within the neighborhood of the concerned point on a contour line. Then the point is to be moved horizontally so that the point is dropped on the computed surface.
    Local DTM of the neighboring points are so strongly correlated to each other that we can obtain smooth contour lines consist of the moved points.

    Exact determination of image coordinates of ground control points is very important for the geometric correction of satellite image data.
    A new method to determine the image coordinates of ground control points more accurately than an usual method is proposed in this paper. This method is an application of template matching method where real Landsat images are compared with computer simulated images representing land use of the exact area.
    Firstly, this method is clarified to be useful through computer simulation.
    Then, this method is applied to an actual image data of Landsat-5 TM. Comparing the RMSE (root mean sqaare error) around eight ground control points by an usual method with those by a new method, the RMSE decreased from 9.6m obtained by an usual method to 3.8m obtained by a new method.

    A new type of stereoscopic image display module has been developed, which has an ability to display both stereoscopic images and stereoscopic graphics simultaneously by using liquid crystal shutter glasses. Using this module a low cost PC-based stereoscopic image processing system has been developed. Two application examples using this system have been expressed. One is three dimentional measurement system and the other is GIS. It can be said that this stereoscopic image display module is very useful as man-machine interface of stereoscopic images.
