The topographical characteristic features of a land surface landforms, elevation, rocks, soils, and vegetation. The study was undertaken to prepare an inventory of terrain characteristics. The study area is North latitudes 17d27’00”: 18d18’00”and East longitudes 77d 28’00” and is included in Survey of India toposheets 56G6, 56G10, 56G13, 56G14, 56G15, 56K02, 56K03, 56K06, and 56K07).

The accuracy of thematic maps derived from remote sensing is often viewed negatively. This reflects difficulties in mapping but also issues connected with accuracy evaluation targets and assessment approaches. This paper focuses on the latter issues suggesting that the widely used target accuracy of 85% may often be inappropriate and that the approach to accuracy assessment adopted commonly in ...

We present a method for mapping the content of a text collection. This method uses linguistic analysis to relate terms extracted from the texts and clusters them into thematic topics mapped onto a 2D space. While the graphic display of domain topics is useful for several information-driven tasks, the focus of the paper is more on the comparison of journal ranking by productivity (number of publ...

The estimation of accuracy of thematic maps derived from remotely sensed data used in conjunction with a geographic information system is presented. A systematic random sampling techique is proposed to asses the accuracy. The main objective of this work is the determination of the optimal sampling intensity and the appropriate sample size used to assess the accuracy. The data set used is a Land...
