ABSTRACTThe Roman military presence at Dalswinton is reassessed using a range of remote sensing techniques (geophysical survey, LiDAR and aerial photography). At Bankfoot the absence of internal buildings suggests the postulated vexillation fortress was a more temporary structure; while numerous pits/ovens were identified across the interior of the large Stracathro-type camp. The primary fort at Bankhead was provided with in-turned entrances and two small annexes attached to the north-west and south-east quadrants of the fort. A third much larger annexe extended southwards down to the river. Only pits and furnaces were recorded within the annexes, two of which were expanded in Phase 2. Various buildings, including legionary and auxiliary barracks, were identified in the expanded fort of Phase 2, whose orientation remained unchanged. A mixed garrison of legionaries and auxiliary cavalry is indicated for both periods of occupation. Finally, the fort was deliberately demolished. The Roman attribution of the three nearby enclosures at Butterhole Brae can no longer be supported.

En los últimos años hemos asistido a un incremento exponencial del número de evidencias arqueológicas relacionadas con la presencia del ejército romano en el noroeste peninsular. En este trabajo analizamos un conjunto de recintos identificados en el oriente gallego mediante el empleo de una metodología específica que aúna técnicas de teledetección y métodos de prospección arqueológica convencional. Estos yacimientos podrían identificarse como asentamientos militares romanos, de acuerdo con sus particulares características morfo-tipológicas. En las siguientes líneas se describen las estructuras arqueológicas documentadas, se analiza su patrón de asentamiento y se estudian sus relaciones con el territorio circundante con la ayuda de diversas tecnologías de información geográfica. ENG:NEW ARCHAEOLOGICAL DATA FOR THE STUDY OF THE ROMAN MILITARY PRESENCE IN EASTERN GALICIAABSTRACTThe archaeological evidence related to the presence of the Roman army in NW Iberia has exponentially increased in recent years. In this paper, we analysed a number of sites identified in the Galician easternmost territories by using a specific methodology which combines remote sensing techniques and conventional archaeological survey methods. These enclosures could be identified as Roman military sites, according to their particular morpho-typological characteristics. The goal of this work is to describe the documented archaeological structures, but also to analyse the settlement pattern of these sites, and to study their relations with the surrounding territory, thanks to the help of various geographic information technologies. KEYWORDSArchaeology; Survey; Remote Sensing; GIS; Fortifications; Roman period; NW Iberia

AbstractThis paper outlines selected remote sensing techniques and their application to civil engineering surveys.In BS 5930, emphasis has been placed on the interpretation of black and white aerial photography to provide information. However, other techniques such as true colour and false colour infrared photography, thermal infrared, radar and landsat satellite imagery may be useful in appropriate applications.

Land is a main life support resource to third world countries. In Nigeria, a major limitation to sustainable land use resources planning, development and management is the unreliable assessment of t available stock and the level of utilization . In particular, the commonly adopted traditional techniques for the evaluation are as questionable as the sources and quality of data adopted and the results being generated. Th is paper is on evaluation of the per capita farm - size holdings by pre dominantly peasant farmers in a pure agrarian environment of the country, using the interactive remote sensing technique and Geo -Informat ion System, a computer -based approach for acquisition, integration and processing of spatially-referenced data and their geographical attributes. The area evaluated covers, in parts, six Local Government Areas (LGAs) in the North West Geo -political Zone of the country. The typical Sudano -Sahellian region is within the flood plains of River Sokoto, River Rima and their tributaries which drain the adjoining upland areas into the main River Niger. Remotely -sensed SPOT data of the area were interpreted to assess the extent of the agricultural land cover and uses. Collateral data were from administrative sources, literature searches and field activities. They were integrated to determine the total area extent of the farmlands within both the upland areas which are cultivatable only in a short wet season of les s than three month per annum; and the prime floodplain areas which are cultivable all year round. The results were in turn related to the farming population in the region to determine the average lands being cultivated per farmer over the two sub -regions. The findings show that 65.9% of the agricultural lands are in upland regions , and the remaining 34.1% within the floodplain. Farm holdings per head are determined at about 0.61 ha ( about 7m by 7m) and less than 0.1 ha ( about 3m by 3m) in the two areas respectively. The paper discusses the implication for food security and sustainability in the region.

AbstractHydrogen sulphide eruptions with their typical turquoise discolorations at the water surface are a unique phenomenon along the Namibian coastline. The remote sensing techniques of ocean colour sensors and microwave scatterometers were used for the investigation of such events. The studies with ocean colour sensors showed that the turquoise discolorations near the Namibian coast were neither linked to dust deposition into the water column by desert storms nor to the reflection of bright material in shallow water areas. In addition, other coloured marine events like algae blooms and river outflows were differentiable from the hydrogen sulphide eruptions by their special optical properties. Quasi-true colour images and spectral identification methods were utilised to monitor and investigate the spatial and temporal distribution of sulphide events. In the past years, they were sometimes and locally limited discovered. Newest remote sensing observations including our own investigations have established that the occurrence of sulphide events is more frequent and longer lasting. The north-westerly direction of propagation and their velocity between 12 cm s-1 and 15 cm s1 were derived from an event on 14 April 2004. Lastly, the microwave scatterometer remote sensing was applied to investigate the relation of sulphide events to oceanographic conditions. The events from May 2004 were clearly related to strong coastal upwelling.
