Satellite Imagery Cadastral Features Extractions using Image Processing Algorithms: A Viable Option for Cadastral Science  [PDF]
Usman Babawuro,Zou Beiji
International Journal of Computer Science Issues , 2012,
Abstract: Satellite images are used for feature extraction among other functions. They are used to extract linear features, like roads, etc. These linear features extractions are important operations in computer vision. Computer vision has varied applications in photogrammetric, hydrographic, cartographic and remote sensing tasks. The extraction of linear features or boundaries defining the extents of lands, land covers features are equally important in Cadastral Surveying. Cadastral Surveying is the cornerstone of any Cadastral System. A two dimensional cadastral plan is a model which represents both the cadastral and geometrical information of a two dimensional labeled Image. This paper aims at using and widening the concepts of high resolution Satellite imagery data for extracting representations of cadastral boundaries using image processing algorithms, hence minimizing the human interventions. The Satellite imagery is firstly rectified hence establishing the satellite imagery in the correct orientation and spatial location for further analysis. We, then employ the much available Satellite imagery to extract the relevant cadastral features using computer vision and image processing algorithms. We evaluate the potential of using high resolution Satellite imagery to achieve Cadastral goals of boundary detection and extraction of farmlands using image processing algorithms. This method proves effective as it minimizes the human demerits associated with the Cadastral surveying method, hence providing another perspective of achieving cadastral goals as emphasized by the UN cadastral vision. Finally, as Cadastral science continues to look to the future, this research aimed at the analysis and getting insights into the characteristics and potential role of computer vision algorithms using high resolution satellite imagery for better digital Cadastre that would provide improved socio economic development.

Refinement of Cadastral Maps
Alena Berková
Acta Montanistica Slovaca , 2011,
Abstract: The amended cadastral ordinance takes effect from 1.7. 2009. Until this date the only cadastral maps for which two listsof coordinates for detailed survey points were filed were digitalized cadastral maps in stable cadastre coordinate systems. The entry intoforce of the amended ordinance has introduced the obligation to file these lists in all forms of cadastral maps. We have one file withcoordinates of image and a second one with coordinates of position. The accuracy of the detailed survey points is defined by a qualitycode. The quality code is indicated in only one of the lists: either that of the image coordinates or that of the positional coordinates.The type of quality code depends on the willingness of property owners to sign a substantiating declaration of consent regardingthe demarcation of a boundary line or the refinement of a boundary line. An integral part of the substantiating declaration is a surveysketch. The paper deals with survey sketch variants with regard to the amended ordinance.

Abstract: Osteoprotegerin (OPG) is a protein that inhibits of osteoclastogenesis. The aim this study was to evaluate the response of serum OPG levels to neridronate treatment in patients with Paget's disease of bone resistant to previous therapy. Nine patients (4 men) affected by active Paget’s disease of bone (6 polyostotic, 3 monostotic) not responsive to clodronate were studied. Serum OPG, osteocalcin, total and bone isoenzyme of alkaline phosphatase (AP and BAP, respectively), and urinary deoxypyridinoline (DPD) were measured before and 5 months after neridronate treatment (100 mg/day, i.v. for two days). A scintigraphic activity index (SAI) was also calculated before treatment. Mean baseline OPG levels were within normal values and were not significantly different 5 months after neridronate treatment. In contrast, there were significant reductions in AP (41.9%, p<0.02) and BAP (38.8%, p<0.04). Serum OPG levels correlated with DPD (r=0.925) and SAI (r=0.689). Although OPG is an important regulator of bone metabolism, in our series of already treated patients it was not a sensitive marker for diagnosing Paget's disease and for monitoring the response to pharmacological treatment, whereas AP and BAP confirmed their clinical usefulness. This preliminary study requires confirmation by a study with a larger population.

The creation of geometrical plan on the boundary of two cadastral areas with a digitized cadastral map.  [PDF]
Alena Berková,Ji?í Bure?
Acta Montanistica Slovaca , 2005,
Abstract: After reconstruction of communication passing through two cadastral areas, geometrical plans were made for the property dividing for each areas independently. The cadastral boundary is a water flow. The digitized cadastral maps of the former cadastre in the Cassini - soldner datum in the scale 1:2880, (the coordinate system St. Stephan), were used. The contact of drafting on the cadastral boundary was not adjusted. The changed boundary and reference points were surveyed in the field in the datum JTSK. The surveyed data were transformed into digitized maps separately for each cadastral area. The unadjusted cadastral boundary, many calculations and also the lack of reference points casued main difficulties. These problems are solved by digitized cadastral maps in datum JTSK with adjusted cadastral boundaries.

ATBU Journal of Environmental Technology , 2011,
Abstract: The study integrated and updated the entire Fadama-mada area with a comprehensive digital map and cadastral data. The raster image from the analogue maps was also fully utilised. Scanned images were sent to Auto CAD environment for proper geo-referencing. Positions of updated features were added using coordinate geometry (COGO). Drawings were properly edited using Arc view 3.2. Graphics were linked with non-spatial attributes data base. The result of this exercise was checked by some GIS operation and analysis; digital map of Fadaman-Mada was produced; and feature details shown in graphics and tables. Thus, for sustainable development, Cadastral Information System (CIS) has been made more effective for the monitoring, evaluation and management of cadastral records in government ministries, local government offices as well as other related government agencies.

Abstract: Remotely sensed imagery provides a useful tool for land managers to assess the extent and severity of post-wildfire salvage logging disturbance. This investigation uses high resolution QuickBird and National Agricultural Imagery Program (NAIP) imagery to map soil exposure after ground-based salvage operations. Three wildfires with varying post-fire salvage activities and variable ground truth data were used to evaluate the utility of remotely sensed imagery for disturbance classification. The Red Eagle Fire in northwestern Montana had intensive ground truthing with GPS-equipment logging equipment to map their travel paths, the Tripod Fire in north central Washington had ground truthed disturbance transects, and the School Fire in southeastern Washington had no salvage-specific ground truthing but pre-and post-salvage images were available. Spectral mixture analysis (SMA) and principle component analysis (PCA) were used to evaluate the imagery. Our results showed that soil exposure (disturbance) was measureable when pre-and post-salvage QuickBird images were compared at one site. At two of the sites, only post-salvage imagery was available, and the soil exposure correlated well to salvage logging equipment disturbance at one site. When ground disturbance transects were compared to NAIP imagery two years after the salvage operation, it was difficult to identify disturbance due to vegetation regrowth. These results indicate that soil exposure (ground disturbance) by salvage operation can be detected with remotely sensed imagery especially if the images are taken less than two years after the salvage operation.
