The benefits from the use of the features attributes and the availability of different types of features on images (pointor linear-features) have raised the importance of using different feature-based transformation models for satellite image registration and terrain modeling. In the last decades, several research works have been conducted to facilitate the use of pointor linear-feature based t...

First-order soil surveys (scales 91:12,000) are essential for detailed land use assessment. Recently developed technologies depicting landscape variability at high resolution are useful for first-order survey development. Our objective was to compare a first-order soil survey created using conventional techniques versus a multivariate firstorder survey developed using terrain attributes calcula...

The Kalman recursive algorithm has been very widely used for integrating navigation sensor data to achieve optimal system performances. This paper explores the use of the Kalman filter to extend the aggregation of spatial multi-criteria evaluation (MCE) and to find optimal solutions with respect to a decision strategy space where a possible decision rule falls. The approach was tested in a case...

At I/ITSEC 2015, we presented an approach to produce geo-referenced, highly-detailed (10cm or better) 3D models for an area of interest using imagery collected from cheap, commercial-off-the-shelf, multirotor Unmanned Aerial Systems (UAS). This paper discusses the next steps in making this data usable for modern-day game and simulation engines, specifically how it may be visually rendered, used...

Primary topographic attributes play a critical role in determining watershed hydrologic characteristics for water resources modeling with raster-based digital elevation models (DEM). The effects of DEM resolution on a set of important topographic derivatives are examined in this study, including slope, upslope contributing area, flow length and watershed area. The focus of the study is on how s...

In this exploratory study, we adopted an existing analytical framework, based on the assessment of resilience in complex adaptive systems. This approach has been successfully applied, for example in the management of complex social-ecological systems. It emphasizes the apparent self-organizational and transitional character of complex adaptive systems, and denotes an intervention strategy based...

There is a growing need for an area-wide knowledge of SOC contents in agricultural soils at the field scale food security and monitoring long-term changes related to soil health climate change. In Germany, maps are mostly available with spatial resolution 250 m 1 km2. The nationwide availability both digital elevation models various resolutions multi-temporal satellite imagery enables derivatio...
