You wrote a bundle? n Maintainability – – n Portability – – n modular approach input/output independent system independent scalability Expandability – – observation types resolution techniques Catherine Le Cocq IWAA 97

Description Catherine Le Cocq IWAA 97

Input Stage: Data Format typedef struct { int typ; char nam[9]; int sel; double x[8], sx[8]; int d[8]; int ilump; int iprimary; } edit_sta; typedef struct { int sel; char nam 1[9]; double h 1; char nam 2[9]; double h 2; double val, sval; int itime; } edit_mes; typedef struct { char nam[9]; int sel; double x[3], sx[3]; int d[3]; int ilump; int iprimary; } edit_tar; typedef struct { int typ; double r; double x. O[3]; double h. O; } model; Catherine Le Cocq IWAA 97

Competitive Analysis n Strengths – – – n data protection portability expandability blunder detection unusual features Weaknesses – – memory size limited earth model Catherine Le Cocq IWAA 97

Real Life Examples Catherine Le Cocq IWAA 97

How long for 1 iteration? Catherine Le Cocq IWAA 97

Future Directions n n Photogrammetry – thorough testing – integration with image acquisition New types of observations – – n point transfer coordinates differences New integrations Catherine Le Cocq IWAA 97
