Abstract:

Highlights New publicly accessible drainage design QGIS plugins were developed. These tools were successfully used to create topologically-sound subsurface drainage layout networks. The tools are easy to use and reduce the level of expertise required to prepare drainage networks that can be successfully sized and buried. Abstract. An important step in designing a drainage system is laying out the network. Successful installation and sizing of the system require that the network be topologically sound and unidirectional. Online digitization of drainage systems does not always result in networks

Abstract. Citizen science has emerged as a powerful way to involve the public in scientific research, especially in domains like environmental sciences, where participants actively collect data in the field. However, citizen scientists can contribute beyond data collection by engaging in data analytics to generate meaningful insights in collaboration with researchers. To support this broader participation, user-friendly and accessible tools for data visualization and analysis are essential. This study addresses this need in geospatial tools by introducing QGIS Light, a simplified version of th

In geoinformatics, spatial data detailing determines how detailed a particular object is representeda map image, and the detail score allows you to analyze the permissible accuracy of spatial objects for a specific user task. An approach to the definition of detailing concept is proposed. The evaluation of the object’s detail depends on its characteristics: geometric, semantic, and topological. A study is being conducted to select the geometric characteristics of the object that reflect its detail. For linear ob
