Study on spatial distribution of horizontal geodetic control points in rural areas

Abstract

The paper presents the results of research concerning the analysis of spatial distribution of detailed geodetic control points in rural areas in Poland. The analysis takes into consideration the relations between the number of geodetic control points and land cover type (built-up, agricultural, and forest) as well as the effective legal regulations in Poland with regard to the issues. The analysis results were referred to geodetic sections classified by the k-means method with respect to the number of the control points and the built-up, agricultural and forest areas. The research indicates that the number of the geodetic control points in an area depends to the extent of 35 % on the type of land cover (building, agricultural and forest land). Having this in mind, the authors recommend taking the land cover into consideration already in the phase of designing a geodetic control network.

Geographical data sets fitness of use evaluation

“…cartography (Steiniger et al 2008), photogrammetry (Zhang et al2013;Zhang et al 2010;Rau, Chen 2003), geodesy (Bielecka et al 2014b), urban geography as well as spatial and physical planning (Montero et al 2010), disaster damage assessment (Takashima et al 2003); -information on building locations and characteristics is of utmost importance to economic sustainable development (Li et al, 2014) and is essential for public administration and citizens (Frank et al 2004); -they are reference data for other data (e.g. address points) (D2.8.III.2, 2013).…”

GIScience Theory Based Assessment of Spatial Disparity of Geodetic Control Points Location

“…High-order geodetic stations are dispersed regularly [25,39,73,74], and this evenness is only slightly disturbed in densely urbanized areas [23] or those with challenging environmental conditions [75]. At the local level, based on Poland as a case study, the clustered distribution and its relation to land cover/land use is evident and well documented [22,29,30], and the analysis revealed high clustering along roads, water courses, and in dense urban areas. High-order geodetic control networks, with regularly dispersed reference stations, define the geodetic reference system in Poland [16].…”

“…Although there is a variety of studies considering the design and densification of geodetic control networks [16,24,25] as well as investigating the influence of topographic objects that hinder the visibility of the horizon, interfere with satellite signals, and, finally, affect the quality of geodetic control stations' positioning [26][27][28], a profound analysis of the spatial pattern of geodetic control points still requires investigation. The problem of geospatial distribution of geodetic control points was previously discussed in several publications [29][30][31]. However, these studies were concerned with the detail (third-order) of geodetic network point analyses in relatively small (less than 200 sq.…”

Spatial pattern of ASG-EUPOS sites

“…In geodesy, especially in analyzing the geographical location of geodetic control points, spatial pattern analysis is of utmost importance [8][9][10]. This is because the main goal of establishing a geodetic network is to determine the position of net points for positioning or monitoring the deformation of the Earth's crust [11].…”
