GCPs are used in the orthorectification process to augment the geometric parameters embedded in the raw image and improve the accuracy of the resulting orthorectification. Orthorectification is a process of removing distortion from an image caused by the curvature of the Earth and changes in terrain....
The construction sector is one of the biggest sectors responsible for the growth of the polymer industry, accounting for 19.8% of all plastic consumption in Europe [11]. In Canada, the number is even larger, with construction responsible for 26% of plastic entering the market [4]. Figure1sho...

geometric and technical point of view. Particularly demanding is the fact that the individual frame members all meet each other at different angles in space, as shown inFigure 1c,d. The consequence that arises from this is an individual design of each knot of the structure leading to a high...
Browse Figures Versions Notes Abstract The correct planning of investment costs and the effective monitoring of implementation process are significant problems in the management of investment projects. At the stage of construction works, it is worth determining the trend of the performed cost curve and...
candidates are compared pairwise according to the 1–9 relative ranking scale provided by Saaty to form a comparative judgment matrix. The scoring matrices of all experts are combined into a judgment integration matrix using the geometric mean method, and the weight value of each candidate relative...
This parameter can be predicted by the 3D geometric relationship, so relatively random influence is small and easy to handle in the control program. Therefore, the proposed compensation model ignores the influence of the quality of the radiation accuracy of the laser source. The conversion accuracy...
