Narrow-angle photography poses special problems in the relative orientation procedures. These are investigated here by the properties of orthographic pictures which correspond to ultra narrow-angle photographs.
窄角摄影在相对定位过程中存在特殊问题。本文通过与超窄角照片相对应的正射影的性质来研究这些问题。

The paper describes the difficulties, both technical and administrative, in survey for title of small rural holdings in Uganda, and is a follow-up to a paper published in “The Photogrammetric Record” in 1959. No purely photogrammetrical method of survey is possible in present circumstances. In an attempt to reduce field costs and to undertake surveys on a sporadic basis for the more progressive farmers, a greater use of photo-enlargements is being made, without relying on the enlargement for the restoration of boundaries.

The author reviews the IGN map series to be revised, ranging from 1:25 000 to 1:500 000 scale. The present status of IGN map revision is summarised with the trends which can be noticed for increasing the rate of revision or improving the products. Data available for revision are mainly acquired from aerial surveys and from information continuously collected from local offices and agencies. Procedures for managing the series of map sheets and of being kept aware of their status are being computerised. In a similar way, data bases containing contours and names permit more automated derivation and easier renewal. Existing space data are starting to be used in revision but they will not be fully used for that purpose since Spacelab and SPOT products are expected to have better ground resolution and stereoscopic coverage. Information is given on future SPOT products and on the results of SPOT data simulation tests. It may be possible to merge all these data in a vast data bank so that new products, such as space maps, could be published easily. Resume Un apercu est fourni sur le portefeuille de cartes a reviser a l'IGN, allant du 1: 25 000 au 1:500 000, sur l'etat actuel de cette revision et les tendances que l'on peut relever pour en accelerer les rythmes ou ameliorer les produits. Les donnees disponibles pour la revision sont basees essentiellement sur les leves photographiques aeriens et les renseignements recueillis de maniere continue aupres des services et directions responsables localement.

During June and July 1981, synthetic aperture radar imagery was acquired of selected sites in ten European countries as part of the European SAR 580 campaign. Evaluation of this imagery in the UK will be carried out by 18 approved experiments (out of 56 for Europe) when the processed data becomes available to investigators. To assist the evaluation process, a review is given of some recent research on applications of imaging radar in agricultural and urban areas. Research is described which considered the effects of terrain parameters and radar parameters on crop classification accuracy. The relative merits of a quantitative or a qualitative approach in classification of radar data are considered. Combined use of radar and Landsat data achieves a marked improvement in classification accuracy. The development of spatial filtering techniques may assist in the problem in urban areas resulting from the dependence of image tone on the relative alignment of ground features and radar look direction. Resume Pendant les mois dejuin et juillet 1981, on a, dans le cadre de la campagne europeenne SAR 580, recueilli des donnees de radar imageur a synthese d'ouverture sur des sites choisis dans une dizaine de pays d'Europe. Ces donnees seront evaluees au Royaume-Uni au moyen de 18 experiences ayant ete acceptees (sur un total de 56 menees en Europe); ce travail commencera des que les donnees une fois traitees seront distribuees aux chercheurs. Pour accompagner cette procedure d'evaluation, on fournit une analyse de quelques recherches recentes sur les applications de l'imagerie radar aux zones agricoles et urbaines. L'une de ces recherches prenait en compte les effets des parametres lies au terrain sur l'exactitude de la classification des cultures. Les merites reciproques des approches quantitatives et qualitatives dans la classification des donnees radar sont egalement examines. Le recours a une combinaison de donnees radar et Landsat permet d'ameliorer de maniere significative l'exactitude de la classification. La mise en oeuvre des techniques de filtrage spatial peut aider a reduire, dans les zones urbaines, les consequences nefastes sur la tonalite de l'image, d'objets au sol en alignement relatif avec la direction d'observation du radar. Zusammenfassung Im Juni und Juli 1981 erfolgten Radaraufnahmen mittels synthetischer Apertur von ausgewahlten Gebieten in 10 europaischen Landern als Teil der Europaischen SAR 580 Kampagne. Die Analyse dieser Aufzeichnungen wird im Vereinigten Konigreich durch 18 (aus insgesamt 56 fur Europa) bestatigte Experimente erfolgen, nachdem die Daten zur Verfugung stehen. Um den Analysenprozess zu unterstutzen, wird ein Uberblick uber kurzliche Forschungen zu Radaraufzeichnungen in landwirtschaftlichen und stadtischen Gebieten gegeben. Es werden auch Forschungen beschrieben, bei denen die Einflusse von Gelandeparametern auf die Genauigkeit der Ernteklassifizierung untersucht wurden. Der relative

Evaluation of this imagery in the UK will be carried out by 18 approved experiments (out of 56 for Europe) when the processed data becomes available to investigators. To assist the evaluation process, a review is given of some recent research on applications of imaging radar in agricultural and urban areas. Research is described which considered the effects of terrain parameters and radar parameters on crop classification accuracy. The relative merits of a quantitative or a qualitative approach in classification of radar data are considered. Combined use of radar and Landsat data achieves a marked improvement in classification accuracy. The development of spatial filtering techniques may assist in the problem in urban areas resulting from the dependence of image tone on the relative alignment of ground features and radar look direction. \u0000 \u0000 \u0000 \u0000Resume \u0000 \u0000Pendant les mois dejuin et juillet 1981, on a, dans le cadre de la campagne europeenne SAR 580, recueilli des donnees de radar imageur a synthese d'ouverture sur des sites choisis dans une dizaine de pays d'Europe.

Since the occasion of the Thompson Symposium in 1979, two new members have joined OEEPE. These are France and the United Kingdom. The possibility of membership had been considered by the UK over the last decade on more than one occasion but, for one good reason or another, no application had been made. In 1980, however, W. P. Smith (Director General, Ordnance Survey) circulated organisations and individuals who might be interested and received an almost unanimous expression of support for an application for membership. This was also in line with the Ordnance Survey's intent to increase its links with other organisations, both nationally and internationally. The Foreign Office agreed that the UK should apply for membership and this was done. The UK became a full member of OEEPE in time for the Oslo meeting of the Steering Committee in 1981. There follows a background paper on the work of OEEPE and accounts of current OEEPE Commission activities.
