Topographic maps contain information related to roads, contours, landmarks, land covers and rivers etc. For any Remote sensing and GIS based project, creating a database using digitization techniques is a tedious and time consuming process especially for contour tracing. Contour line is very important information that these maps provide. They are mainly(More)
Texture describes the surface characteristics object such as plants, skins, terrains etc. This paper is based on the comparative study on various approaches to identify the gray scale texture of an unknown object from a set of texture of a known object available in the database. We have focused on three approaches of comparing the input gray scale texture(More)
Pattern Matching is useful for recognizing character in a digital image. Optical Character Recognition (OCR) is one such technique which reads character from a digital image and recognizes them. Line segmentation is initially used for identifying character in an image and later refined by morphological operations like binarization, erosion, thinning etc.(More)
Contour line extraction from a topographical map is an integral part of Geographical Information System. Traditional technique for contour line extraction include manual digitization, this is a time consuming, tedious and a costly process. In addition the effectiveness of the result highly relies on the ability and skill of the researcher responsible for(More)
— Area of classifying satellite imagery has become a challenging task in current era where there is tremendous growth in settlement i.e. construction of buildings, roads, bridges, dam etc. This paper suggests an improvised k-means and Artificial Neural Network (ANN) classifier for land-cover mapping of Eastern Himalayan state Sikkim. The improvised k-means(More)
Rainfall runoff is an important component contributing significantly to the hydrological cycle, design of hydrological structures and morphology of the drainage system. Estimation of the same is required in order to determine and forecast its effects. Estimation of Direct rainfall­runoff is always efficient but is not possible for most of the location at(More)
Automated information extracted from topographic sheet plays an important role in assisting researchers to extract identifiable features in the field of remote sensing and geographical information system. Extraction and representation of morphological patterns pertaining to an aspect of interest plays a pivotal role while making a quality assessment of the(More)
Perception and expectation of citizens is an important factor in urban planning, settlement and management. Hence, there is a need of a participatory citizen centric planning of urban settlement based on spatial data. These perception and expectation may be represented in terms of emotions. Determining Urban Emotions is an approach which can be used to map(More)
