Recently the total stations and the laser scanners can be available to measure road shape at road paving works by road construction companies. Meanwhile, recent digital camera products provide high-performance and there is a possibility that they will be the other measuring instrument. The purpose of our research is to elucidate the applicability of digital cameras to measure the road shape at the road paving works. In this paper, we report experimental results of applying 3D image processing with a digital camera to a road test piece of asphalt pavement surface with 30 cm square for the road shape measurement.
AxelGlobe is the Earth observation infrastructure for a new era. It will have the ability to image the whole civilized world with a resolution of 2.5m every day. Its advantage is not just in the always-fresh information it will provide, but also in the collection of its past data. Comparing older images and studying their evolution can lead to invaluable insights and predictions for the future. AxelSpace has launched first GRUS satellite as the first piece of AxelGlobe 28th December 2018. This satellite will provide Image products which are described in this document.
A cadastral survey system for mountain forest area using aerial and space remote sensing technologies has been established for solving a difficulty to make onsite parcel boundary demarcation by aged land owners. In the system, the parcel boundaries are interpreted and measured by cadastral surveyors utilizing remote sensing information as well as existing old parcel maps as basic reference data, after making limited amount of field survey with local authority, in order to make tentative parcel maps. Then, the tentative parcel maps are confirmed by land owners at a community center. If the tentative parcel boundaries are approved by the land owners, the boundary data are treated as official cadaster data. In case some tentative boundary data are not approved and onsite demarcations are requested, the data are corrected by field survey. In this paper, an overview of the system is given.
