There is a growing interest in the potential of synthetic aperture radar (SAR) for mapping and for gathering intelligence for map revision. This paper first gives a simple guide to the characteristics of SAR and then describes a study carried out to investigate the geometric properties of the imagery and the information content which is of interest for topographic mapping and the production of large scale plans. The conclusions cautiously indicate a potential although better quality images are required and more information must be known about the optimum conditions which should obtain when the data are recorded.

Ce texte commence par donner un simple rappel des caracteristiques de ces radars pour decrire ensuite une etude effectuee sur le contenu informatif et les proprietyes geometriques de l'imagerie radar, qui interesse la cartographie topographique et la confection de plans a grande echelle. Les conclusions font prudemment etat d'une potentialite mais soulignent qu'il faudrait disposer d'images de meilleure qualitye et avoir davantage d'informations sur les conditions optimales a respecter lors de l'enregistrement des donnees.

Different methods of analytical block adjustment are outlined and classified. Results of some practical experiments are summarized. A simple solution for block adjustment is discussed, where strips are divided into space sections. Air-station points are included in the solution to preserve, in the strips, their power of bridging. All sections are adjusted to the best fit with regard to each other as well as to ground control, by change of scale, rotations and shifts. To avoid the simultaneous solution of a very large number of equations in a corresponding number of unknowns, a simple iterative solution is used.

The algorithm presented assumes a preliminary determination of the elements of inner orientation and bases its mathematical model on the collinearity condition, from which projective equations are derived. Linearisation of condition equations is based on Taylor's expansion, whilst the subsequent solution follows iteration cycles. The method aims to derive composite corrections to image coordinates, with the aid of test field data. Resume L'auteur presente un algorithme ou l'on suppose determines au prealable les elements d'orientation interne. La modelisation mathematique s'appuie sur les conditions de co-linearite et sur les equations qui en resultent en projection. On linearise les equations de conditions en utilisant un developpement en serie de Taylor, et l'on obtient la solution correspondante par iteration. La methode vise a apporter des corrections aux coordonnees images en utilisant les donnees d'un polygone d'essai. Zusammenfassung Bei dem dargestellten Algorithmus wird die vorlaufige Bestimmung der Elemente der inneren Orientierung angenommen, und das mathematische Modell basiert aufder Kollinearitatsgleichung, woraus perspektive Gleichungen abgeleitet werden. Die Linearisierung der Bedingungsgleichungen erfolgt durch Anwendung der Taylor-Reihe, was fur die folgenden Berechnungen einen iterativen Prozess bedingt. Mit der Methode wird angestrebt, Bildkoordinaten mit Hilfe von Testfelddaten zu verbessern.

Analytical aerial triangulation is widely computed on electronic digital computers up to the block adjustment stage. Various possibilities for an analytical block adjustment are under consideration and one such method has been programmed at the Ordnance Survey of Great Britain. This paper briefly describes this adjustment and the trials so far conducted upon it. The trials suggest considerable economy without loss of accuracy when compared with the Jerie Analogue Computer at present in use.
