The evolution of terminology in a given field of science and technology is a good indicator of the context in which inventions originated and how concepts have evolved. This is the case of photogrammetry, remote sensing and related methods, whose terminology evolved, first under the influence of the early inventors Laussedat and Meydenbauer, in French and German, respectively, and then in English and other languages as an international professional community developed. The development of space remote sensing and analytical photogrammetry led to the modification of old concepts and the renewal of terminology, and more recently, the advent of digital photography has blurred the boundaries between different fields and the meaning of the terms. This article proposes an analysis of the evolution of technical terms through the Google Ngram Viewer tool, which allows the visualization of the occurrence of terms in documents accessible on the web. Despite its biases, this tool allows an interpretation of the evolution of the terminology over a long period of time, as well as a comparison of the evolution observed in the different languages. In particular, it makes it possible to highlight the periods when these methods were very popular, as well as a recent decline in the use of classical terms such as photogrammetry and remote sensing in favor of a new vocabulary, due to the blurring of boundaries between disciplines and to the emergence of new solutions related to UAVs, computer vision, etc., which have renewed the potential of classical methods.

A method using remotely sensed data was developed to map the incidence of Q fever in the vicinity of Cayenne, French Guiana. A satellite image was processed to map land cover and generate a population density index, which was used to determine areas of high disease incidence during the 1996-2000 period. A comparison with results obtained using population census data showed strong concordance between the two incidence maps. All high-incidence areas identified using population census data were also detected using remotely sensed data. This demonstrates the potential of remote sensing as a new tool for rapid mapping of disease incidence in epidemiologic surveys. [ABSTRACT FROM AUTHOR]

The author discusses the technological innovations in the field of photogrammetry in France. In the area of photogrammetry and remote sensing, the French scientific community has always taken initiative to form a national society. Parallel to the outstanding developments of high resolution optical imagery, the French community has designed range of radiometers and imaging radar sensors in the supervision of the European Space Agency.

Within the framework of an environmental impact study of aquacultureactivities in the coastal marsh of Mahajamba (North-Western Madagascar), an assessment of the environmental conditions existing prior to the onset of aquaculture activities (production began in October, 1993) is essential. To this end, the area was mapped using SPOT-XS data,which made it possible to define the main ecodynamic tendencies of the mangroves before the development of the rearing ponds. The aim wasthen to implement fast, precise and reliable mapping methods, makingit possible to follow mangrove alterations resulting from these aquaculture activities. Analysis of the radiometric behaviour of the various plant formations of the marsh, based on SIR-C radar data, revealed that the discrimination between these formations is easier when thefrequency used is low and the polarization is crossed. Thematic analysis using textural classification was carried out with the L-band and polarization VH. The results generated are promising insofar as themapping of mangroves is concerned with a fast treatment time and acceptable precision of the results. [ABSTRACT FROM AUTHOR]
