This paper discusses two aspects of the new DTM generation project, the product view from the perspective of the owner (Ordnance Survey) and the technical solution for combining DTMs from the system supplier (Inpho). Ordnance Survey (OS) has a long history of providing height information in a national context from both precise geodetic levelling networks and photogrammetrically surveyed contour...

The Indiana Philosophy Ontology (InPhO) project is presented as one of the first social-semantic web endeavors which aims to bootstrap feedback from users unskilled in ontology design into a precise representation of a specific domain. Our approach combines statistical text processing methods with expert feedback and logic programming approaches to create a dynamic semantic representation of th...

We describe a decision support system to assist in the preparation and evaluation of agroindustrial investment projects, called Agriventure. This system has been specifically designed to address the special characteristics of agroindustrial projects. The system facilitates the laborious process of organizing the technical and economic information needed to assess a project’s financial feasibili...

This paper deals with the production of digital surface models (DSM) from high resolution images. The paper explains why the quality of the dense DSM depends on the quality of input data and data compilation. The INPHO GmbH software MATCH-T DSM has been redesigned to produce very dense DSM data. The most important improvement was the introduction of sequential multiimage matching. The point ext...

The application of digital humanities techniques to philosophy is changing the way scholars approach the discipline. This paper seeks to open a discussion about the difficulties, methods, opportunities, and dangers of creating and utilizing a formal representation of the discipline of philosophy. We review our current project, the Indiana Philosophy Ontology (InPhO) project, which uses a combin...

Image matching is currently gaining increased interest in the photogrammetric community to provide accurate and very dense point clouds for Digital Elevelvation Models (DEMs). Besides the traditional Digital Terrain Models (DTMs) the focus is more and more on Digital Surface Models (DSMs). It can be seen as an alternative technique or even competition to airboren laserscanning (LIDAR) which is ...

The Chinese Loess Plateau suffers from serious gully erosion induced by natural and human causes. Gully-affected areas detection is the basic work in this region for gully erosion assessment and monitoring. For the first time, an unmanned aerial vehicle (UAV) was applied to extract gully features in this region. Two typical catchments in Changwu and Ansai were selected to represent loess tablel...

This article describes the configuration and technical specifications of a multi-rotor unmanned aerial vehicle (UAV) using a red-green-blue (RGB) sensor for the acquisition of images needed for the production of orthomosaics to be used in archaeological applications. Several flight missions were programmed as follows: flight altitudes at 30, 40, 50, 60, 70 and 80 m above ground level; two forwa...

The explosion of semantic data on the information web, and within digital philosophy, requires new techniques for organizing and linking these knowledge repositories. These must address concerns about consistency, completeness, maintenance, usability, and pragmatics, while reducing the cost of double experts trained both in ontology design and the target domain. Folksonomy approaches address co...
