Symposium on Remote Sensing for Dn ^^nrces Development and Environmental Management / Enschede / August 1986 569 Comparison between interpretations of images of different nature G.Bollettinari Morfogeo s.a.s., Ferrara, Italy F. Mantovani Ferrara University, Italy ABSTRACT: Data obtained analaizing images of different nature, are described to interprete from the neotectonic point of view some geomorphological feactures of the central and northern area of Perù. The purpose of this pa per is the research of the relations ship between photointerpretation, obtained data and their reliability. Particularly merits and shortages,interpretative limits, and the fitness use of each type of images for the over mentioned work, will be described. RIASSUNTO: Vengono descritti i dati ottenuti analizzando e confrontando immagini di differente natura, con lo scopo di interpretare in chiave neotettonica le caratteristiche geomorfologiche dell'area centro settentrionale del Perù. Scopo della presente nota è la ricerca dei rapporti intercorrenti fra fotointerpretazione, dati rica vati e loro attendibilità. In particolare vengono sottolineati i pregi e le carenze riscontrati, per ciascuna immagine, al fine di tracciare i limiti del dettaglio interpretativo e la destinazione d'uso più idonea. 1 INTRODUCTION The following note is in reference to the preliminary, photointerpretative phase of a multi-faceted study aimed at identifying the principle neotectonic featu res of a high plain area in the Peruvian Andes. In particular is here analyzed a photointerpreta tion process applied to different types of images and the morphoneotectonics classification also used. At the end, the various advantages and disadvantages of each type of image is underlined, indicating any limi tation in interpretative detail and, based on the re sults, the use to which it is most suited. 2 PHOTOINTERPRETATION PROCESS The area studied is in the Peruvian Andes N 10° Lat S within a 100-Km-wide area extending approximately 400 Km NNW-SSE and including the Andean high plain. The following documents were used: a- LANDSAT images, average scale 1:250,000, spectral band 7; b- LANDSAT F.C.C. (false colour composite) images obtained by automatic procedure of spectral bands 4, 5 and 7, average scale 1:250,000; c- SLAR black and white photomosaic images, average scale 1:100,000; d- Panchromatic black and white photomosaic aerial photographs, average scale 1:100,000. The procedure followed two successive phases of the photographic documents available. The first phase consisted of a field assessment of those photoalignm ents of certain natural origin to which a tectonic meaning could be attributed; that is association with faults or fractures. The second phase consisted of a classification of the natural, tectonically signifi cant photoalignments in the above-mentioned field: those which were not fully developed were eliminated unless fully aligned or associated with other alignm ents . 2.1 Phase 1. Assessment and distribution of total field For assessment and distribution of the tectonically significant natural photoalignments of the total field the procedure was as follows: a- Interpretation of the black and white LANDSAT images; b- Interpretation of the F.C.C. LANDSAT images; c- Interpretation of the SLAR images; d- Interpretation of the panchromatic black and white photomosaic. In particular the basically straight alignments as well as circular areas were separately identified for each type of image from their photographic and/or morphological expressions. The former were seen as variations in tone, texture, structure, contrast, glossiness, etc. of the object. The latter define va rious alignment patterns: lithological (contact bet ween different lithotypes), structural (dip and stri ke, faults, fractures, etc.), hydrographic and orogra phic (water courses, valleys, watersheds, escarpments, etc.). 2.2 Phase 2. Classification of photoalignments from the total field After assessment of the photoalignments had been com pleted they were classified on the following basis: a- continuous photoalignment planimetry; b- correspondence of the photoalignments in the dif ferent images used.
