Data capturing

Nowadays mobile devices are used for data capturing using Global Navigation Satellite Systems (GNSS) (e. g. GPS, GLONASS) in a standardized and formalized way (Dangermond, 2009; Brandt, 2007) to reduce effort in data conversion to implement and use the results in the
planning process. They are used e. g. to create tree cadastre (Pietsch, 2007; Brandt, 2007; GALK – DST, 2006), to collect species presence datasets (Dangermond, 2009), to reduce time and costs capturing land use types or habitats and for monitoring (e. g. checking mitigation measures). Depending on the hardware capacity and performance and the receiver accuracy improvements in data collections are possible. Using UMTS or other online services datasets might be send to a server (e. g. in the office) on the fly without necessary active copying or basic datasets like aerial images, top maps, thematic layers (e. g. streets) or the datasets that have to be checked can be received via Web Services (e. g. WMS, WFS) to be used online in the field. Digital cameras with a GNNS module facilitate documenting the investigation area. Images with coordinates are stored and some cameras and applications are able to analyze the viewing direction automatically. Using techniques like that enable the planner to create automatically documentations based on the existing images to present them e. g. online via Google Earth or to use them in the planning process (e. g. visualization, sketches, participation).
