ABSTRACT:GNSS/INS system composed of Global Navigation Satellite System and Inertial Navigation System together can provide orientation parameters directly by the observations collected during the flight. Thus orientation parameters can be obtained by GNSS/INS integration process without any need for aero triangulation after the flight. In general, positional uncertainty can be estimated with known coordinates of Ground Control Points (GCP) which require field works such as marker construction and GNSS measurement leading additional cost to the project. Here the question arises what should be the theoretical uncertainty of point coordinates depending on the uncertainties of orientation parameters. In this study the contribution of each orientation parameter on positional uncertainty is examined and theoretical positional uncertainty is computed without GCP measurement for direct georeferencing using a graphical user interface developed in MATLAB.
ABSTRACT:The studies of recent crustal movements are based on analyses of repeated geodetic measurements, and their combination with results of geophysical and geological investigations. It is obvious that a single data producer can not produce useful datasets and information without integrating data from others because one scientist's results become another's data. So, the problem to be solved naturally has an interdisciplinary character. However, Earth scientists traditionally work on one aspect of the problem and they have a tradition of sharing of data but they are willing to share it if asked. Because of this, the resources are being wasted in duplicative efforts. However, the goal is for data to evolve it into information, and then into knowledge as quickly and effectively as possible. In order to do this, calculations and analysis need to bring to the desktops of researchers, decision-makers, and educators. The aim of this study is to develop a service-oriented architecture (SOA) based Geographic Information System (GIS) that enables linking and sharing multidisciplinary Earth science data, tools, and software and to provide a wide range of users access to the system and in this way to build an easy-to-use interactive access to data and analysis environment to study earthquakes in Turkey.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
