Before such remote sensing data can be used they have to be processed and prepared for facilitating meaningful interpretation. The scope and importance of image processing and enhancements depend on the sur-face conditions of study area. The peculiar geo-graphical configuration of the Talakadu area has made the greater part of an old township complete-ly buried under wind blown sand from the river Kaveri that skirts the west of Talakadu. Towards carrying out analysis in spatial, spectral and tem-poral domains, space imagery from Landsat Thematic Mapper, Multispectral images from LISS-IV sensor of Indian Remote Sensing Satellite (IRS) series and high resolution images from IRS CAR-TOSAT series were used. Several image-processing algorithms were employed to evaluate their effica-cy to identify linear features and geometrical shapes that might indicate presence of buried remains. These include enhancements and improve-ments in data quality, Pan sharpening, Principal Component Analysis for enhancement and change detection studies. These analyses were conducted after subjecting all the imagery to a common refer-ence frame through automated registration using non-linear methods with sub-pixel accuracy. This work presents the details of the various image pro-cessing techniques used to investigate their effica-cy in the context of identifying the different archae-ological details both known ones and possibly new potential locations. Our preliminary analysis indi-cates at least four likely locations for further archaeological exploration, thus suggesting a new approach in the light of the methodology available.

Airborne remote sensing for archaeological application : prehistorical landscapes in Gargano Area (Italy) / R. Salvini in Photo interprétation, European journal of applied remote sensing, vol 45 n° 4 (novembre 2009)

The geographical context of the project is the Promontory of Gargano (South-Eastern Italy), where the extraordinary availability of flint is associated with evidence of numerous extraction complexes (underground mines) (Galiberti 2005). According to the available data, the mining activities cover a time-span of almost three thousand years; among them, the most important is practiced in the Defensola hill, a mine- the most ancient in Europe- active from roughly 5.800 b.C (Tarantini, 2006). Differently from other European prehistoric min-ing complexes, in the Gargano area, mines were generally opened onto slopes with a convex mor-phology and had often produced extremely large conoidal heaps outside. Digital aerial photogrammetry was used in order to natural and archaeological features of recognize the prehistorical landscape near thr mines. Starting from present and historical geo-morphological evi--dences, thanks to the stereo interpretation of aerial photos that have shown earthworks and soilmarks, it was possible to recognize geological features interpreted as evidence of palaeodrainages and of ancient coastline. The integration between histori-cal references and geological researches through a GIS allowed to join different dataset, in order to highlight the spatial and temporal variations, and to produce thematic cartography.

Multitemporal Satellite High resolution images for the knowledge and the monitoring of the Iraqi archaeological sites: The case of Seleucia on the Tigris / G. Scardozzi in Photo interprétation, European journal of applied remote sensing, vol 45 n° 4 (novembre 2009)

(IBAM) in the "Iraq Virtual Museum" Project of the Consiglio Nazionale delle Ricerche (CM?); in partic-ular, it is focused on the activities for the creation of the section "Archaeological Sites", finalized to the contextual ization of finds stored in the Baghdad Museum. During this work the contribution of high resolution satellite images (Ikonos-2, QuickBird-2, World View-1) was very important, which were taken in 2001 - 2008 and used to document the modern situ-ation of the archaeological areas and tor monitoring their pre/post second Gulf War situations; very important were also the high resolution satellite pho-tos taken by USA spy satellites in 1960s and 1970s, that are useful for monitoring the transformations of the most important archaeological Iraqi areas in the last 30-40 years, before the first Gulf War. The multitemporal remote sensing data used in the Project for the contextualization of archaeolog-ical finds, also allowed to discover new data about ancient topography, urban layout and paleo-environmental context of many ancient cities and archaeological areas; for the study of these sites and territories some aerial photos are also used, taken in the 1920s, 1930s and 1940s by RAF pilots. In some cases, instead, the orthorectification of the recent satellite images and the vectorization of all archaeological remains and traces visible in the satellite images, allowed the upgrade of existing archaeological maps with new data about ancient urban layouts, monuments and roads. An illustra-tive example is that of Seleucia on the Tigris, whose urban layout has been studied in the 20s, 30s and 60s of the 20th century with the use of aerial photographs; the analysis and processing of several satellite images, taken in different moments between 1965 and 2007, allowed to acquire new data on the regular outline of the city's blocks, and to create a new archaeological plan of the site.
