Much local government has been using large scale digital maps with Geographic Information System (GIS). However, the updating method of a map is not established yet. The purpose of this study is the real-time renewal of the digital map for local government by collaboration of REAR TIME GIS and spatial data. In this study, spatial data means Remote Sensing imageries and Real-time Kinematic Globa...

The principle of categorial matching that has been invoked to mandate that transformations of theories by contraction removing some proposition h from a belief state K should include a specification of the entrenchment of the new belief state K − h as well as the entrenchment of the initial state K masks a substantial assumption that ought to be subject to critical scrutiny and which personally...

A “dynamic” geodetic datum is a datum that consists of coordinates and velocities of control points, which can provide users with the realistic positions of sites within the network that reflects the result of local or regional motion induced by a number of causes. A new ITRF-linked scheme is proposed and discussed in order to process available geodetic data in real-time to establish a dynamic ...

In this note, structural decomposition of linear periodic continuous-time systems is discussed. A fundamental problem to decompose a state of a periodic system into controllable and uncontrollable parts is conjectured to be achieved by a continuously differentiable and periodic coordinate transformation with the same period of the system, however there is a counterexample to this conjecture. He...

Nanopositioning and nanomeasuring machines are 3D coordinate measuring systems with nanometer precision at measurement volumes in the cubic centimeter range. The base is formed by an interferometer system a common mirror corner. orthogonality deviations of corner require transformation axes. uncertainty must be taken into account overall budget. Starting from complete model, result model simpli...
