Each pixel is now represented by a vector P(x,y,z,/) where x is column, y line number, z is elevation and I is digital count of the pixel. The bird's eye view generation is divided into two steps. The first one is to find out a projected vector P'(x',y',z') given by azimuth angle, depression angleg , distance d between eye position and view plane. The second one is to assigned digital count to the newly computed pixel. depression angle image X View plane Figure 6. Bird's eye view image generation scheme The projection is then done by the following formulas: x'z xcosq — ysina y'=(xsina + ycosa )cos @ + z sin à z'=(xsina + ycosa )sin à + zcos à "n Uu d =x d+z' n Uu d VS d+z' Where X .. original column number y .. original line number z .. original elevation x .. transformed column number y .. transformed line number z ... transformed elevation x",y" ... projected coordinates in view plane d .. distance between eye position and view plane After the position of the pixel in view plane has been computed, we must assign to it digital count and to decide whether it belongs to hidden surface or not. This will be done by simple resampling algorithm applying for the farthest up to the nearest line from eye position. 4. REMOTE SENSING TRAINING ASPECT OF ASEAN The primary goal of the ASEAN is training and education. All of the functions were designed in a sequence that is intuitive and easy to understand. Many Windows control styles as graying or disabling menu items were used to prevent possible errors, for example, execution of a certain function is blocked when the input data is incomplete, or the print menu is always grayed when the computing process is not yet finished. 38 Figure 7. Bird's eye view image display The computation algorithms of ASEAN were carefully selected and developed to achieve maximal processing speed on PC computers and so ASEAN became a real interactive system. The Arithmetic Operation menu with capability to input arbitrary formula create very interesting module when the user can try various formula for image transform. This is very flexible approach not only for training but research as well. The manual of ASEAN is comprehensive. The help system follows Windows style and provides quick searching of guide for relevant functions. The most interesting feature of ASEAN that is very suitable for training is that most of major functions were recorded by Windows Recorder and sample data. Whenever the user click Tutorial and select a function, ASEAN will perform playback demonstrating visually how to use that function. By such an organization the training or self-training become more attractive. At the present time, the ASEAN is used for remote sensing training in many countries in the SE region and it is released through the annual Regional Remote Sensing Seminar on Tropical Eco-System Management organized by NASDA, UNCRD and ESCAP and other JICA training workshop as public domain software. Regional Remote Sensing Seminars and other NASDA Education on University , JCA Training Rsearch Organization ImaSOFT Lab. and Other Figure 8.
