—Systems interact with real world entities, and must hold internal representations of these entities in order to handle them appropriately. Physical-informatical essence duality (PIED) is the parallel existence of the entity as both the original, usually physical source, and its informatical representation, as held by each agent interacting with the entity.(More)
High Resolution satellite Imagery is an important source for road network extraction for urban road database creation, refinement and updating. However due to complexity of the scene in an urban environment, automated extraction of such features using various line and edge detection algorithms is limited. In this paper we present an integrated approach to(More)
These High resolution satellite data with metadata information is used to extract the height of the building using shadow. Proposed approach divides into two phases 1) rooftop and shadow extraction and 2) height estimation. Firstly the rooftop and shadow region were extracted by manual/ automatic methods using Example – Based and Rule – Based approaches.(More)
Geoinformatics is a highly specialized discipline that deals with Remote Sensing, Geographical Information System (GIS), Global Positioning System (GPS) and field surveys for assessing, quantification, development and management of resources, planning and infrastructure development, utility services etc. Indian Institute of Remote Sensing (IIRS), a premier(More)

—In this paper we deal with the development of a speech to speech system for tourism and emergency services in Indian languages.We discuss the development of the the speech synthesis (TTS), speech recognition (ASR) and machine translation (MT) subsystems of the speech to speech system.We also describe the evaluation of the system and present the results of(More)
The origin of the concept of using contextual information of Correlation in neighborhood of a pixel for change detection is the simple geo-statistical fact that the same geographical area (neighborhood window) on two dates of imagery will tend to be highly correlated if no or little change has occurred and uncorrelated when change occurs. The main objective(More)
Spatial analysis is the vital part of GIS. Spatial analysis in GIS involves three types of operations-attribute query (also known as non-spatial), spatial query and generation of new data sets from the original databases. Various spatial analysis methods viz. single/multiplayer operations/overlay; spatial modeling; geometric modeling; point pattern(More)
The handling of spatial data usually involves processes of data acquisition, storage and maintenance, analysis and output. For many years, this has been done using analogue data sources and manual processing The introduction of modern technologies has led to an increased use of computers and information technology in all aspects of spatial data handling.(More)
