Systematic Cadastral mapping in Nepal used to be carried out using local coordinates. Later National Reference Frame (NRF) and a map sheet layout is being improve the situation. Current trend of use GNSS establishing control points demands set transformation parameters. The coordinates NRF which are obtained by transforming results, does not give expected accuracy for large scale mapping. In ad...

How should a mobile robot explore its environment in order to build a high-quality world model as efficiently as possible? We address this question through experimentation with a sonar-equipped mobile robot. The robot is taken to be a delivery robot, such as could be used in an office, hospital or home. Its objective is to execute efficient collision-free paths between user-specified locations....

the efficiency of three statistical models, ahp surface-weighted density bivariate (semi-quantitative models), stepwise multivariate regression and logistic multivariate regression models were compared in chehel-chai watershed in golestan province, iran. in current study the hazard map was prepared according to the top model of landslide hazard map. chehel-chai watershed is located as one of go...

An essential aspect of map-based navigation is the determination of an agent’s current location based on sensed data from the environment. Formally, this amounts to specifying the current viewpoint in some world model coordinate system. This localization process has two distinct components: one involving the establishment of correspondences between aspects of the sensed data and the map or mode...
