Development of Gis and Web Maps in Order to Extend Water Supply and Sewerage Infrastructure in Lechința Village, Iernut Town, Mureș County

Abstract

In Romania’s most rural parts, the urban networks are not sufficiently developed. In order to improve the living standards of the inhabitants of Lechinta village, Iernut city, Mures county, it is necessary to extend water supply and sewerage infrastructure. For a better visualization and understanding of the interest area, a database was created in which the constructions, buildings, electrical and optical fiber networks, infrastructure and access ways were digitized. Considering the created database and the digital elevation model of the terrain, it was possible to easily design the water supply and sewerage infrastructure that allowed a better management of the field measurements. In order to ensure a higher degree of details, but also to complete and verify the measurements made with GPS receivers, photogrammetric and LiDAR data were obtained using a UAS equipped with the TopoDrone LiDAR 100 Lite sensor and the Zenmuse X4S DJI camera. The field data were imported into the ArcGIS application and analyzed in order to achieve the water supply and sewerage infrastructure. In order to visualize the digitization of the elements in the field, web maps were made using ArcGIS online application. The first map allows a 3D view of the area of interest and the second map includes 5 applications: database visualization, selection of desired layers, determination of distances and surfaces, use of different basemaps as well as sharing information through email, Facebook, etc. Database and webmaps that were created contribute to an easier design of urban networks and the visualization of the land in real time.
