Geographic information systems

It is now almost 40 years since Roger Tomlinson coined the term geographic information system (GIS), and led the development of the world’s first, the Canada Geographic Information System (CGIS), in the mid-1960s (for a history of GIS see Foresman 1998). Today’s technology would be almost unrecognizable to the pioneers of the 1960s, not only because of the almost unbelievable advances in information technology (IT) that have occurred since then, but also because of dramatic changes in the functionality, appearance, use, and societal context of GIS.

This model study was conducted in Antalya region greenhouses for the determination and registration of agricultural resources as a part of adjustment efforts for the European Union (EU) Common Agricultural Policy (CAP). The aim was to create new database systems based on remote sensing (RS) and geographic information systems (GIS), rather than conventional land measurement techniques.

The development of the coastline in Cua Viet outlet area from 1952 to 2015 was quantitatively evaluated using remote sensing technique and geographic information system (GIS). The result of the research shows that in the Cua Viet outlet area the accretion and erosion phenomena occur in a very complex manner, with erosion predominating over accretion in both scale and intensity, in which the coast sections with the largest scale and highest intensity of erosion are usually located near the outlet (both inside and outside the outlet).

The paper is based on the study of distribution of Rhododendron arboreum Sm. in Langtang National Park ranging from 600 m to 7234 m. The study was carried out the Remote-Sensing and Geographic Information System technique. SPOT Image and ERDAS Software have been used for the image processing. The program has detected different ecological parameters in tropical to alpine zone and verified ground truth Rhododendron arboreum of the study.

We describe the spatial distribution of the genus Acantholimon Boiss. (Plumbaginaceae) taxa in Turkey, and assess the role that environmental variables may be playing on this distribution. We collected a large number of specimens from 418 geo-referenced sampling sites between 2000 and 2004, and established a point database using geographic information systems (GIS) software.

The application of remote sensing and geographical information system for the analysis of morphometric parameters are found to be of immense utility in watershed prioritization for soil, water conservation and natural resources management at micro level. Geomorphological analysis is the systematic description of watershed geometry and its stream system. These parameters directly or indirectly reflect the response of entire watershed based on causative factors that are affecting runoff and sediment loss.

Morphometric analysis is important in any hydrological investigation and it is inevitable in development and management of drainage basin. Geographical Information System and image processing techniques can be employed for the identification of morphological features and analyzing properties of basin. The morphometric parameters of basin can address linear, areal and relief aspects.
