07-03: Will Drones Open Up New Ways of Mass Registration?
Comparative Evaluation of Type-Dependent UAV Performance in High-Precision National Territorial Surveying and Spatial Information Acquisition
LX Korea Land and Geospatial Informatix Corporation, Korea, Republic of (South Korea)
This study is mainly concerned with evaluating and comparing the level of accuracy and resolution of images taken from a fixed wing UAV and a rotary wing UAV at the same flying altitude. A test-bed was installed for image data collection using fixed wing and rotary wing UAVs of the same manufacturer. To evaluate the accuracy of UAV imagery, the imaged coordinates were checked against coordinates in cadastral records and coordinates obtained from terrestrial surveying.As a result of comparing UAV-imaged coordinates’ accuracy using an RMSE analysis, the rotary wing UAV was found to have slightly higher RMSE value. While no significant UAV type-dependent differences were confirmed in the digital surface models, both UAV types showed differences from the coordinates in the cadastral records, thus demonstrating the feasibility of UAV application to the project of inspecting cadastral non-coincidence. In resolution analysis, the rotary wing UAV was found to have a slightly higher spatial resolution due to camera orientation parameters, and the fixed wing UAV showed higher visual resolution due to weather conditions. In the comparison of processing time, fixed wing UAV was found to require 25% less time for the work from image acquisition to image analysis.
Could We Cadaster Faster in an Integrated IT System by using UAVs with GIS Services in a Cloud Infrastructure?
Teamnet Group, Romania
There is a significant number of geographies around the world where the percentage of land with cadaster and land books registered in an integrated IT system is rather low and increasing it is a real challenge for all stakeholders: the governmental institution managing the domain, surveyors, IT businesses and citizens.
In order to improve the duration and costs of mass registration we analyze the involvement of modern technologies along the process, automation of eligible registration sub-processes, usage of UAVs for faster field data collection and storing and sharing all work in progress in the cloud infrastructure. We measure the improvements and analyze their impact on quality and total cost of ownership to determine whether such improvements are a real “win” for all stakeholders and obtain promising results: comparing the mass registration process in several scenarios with different levels of automation on the sub-processes reveals a decrease of the duration or cost of sub-processes with 20-40%, a decrease in number of validation iterations with 25-50% and the improvement of public registration service transparency for the citizens.
Case Study On Using New Technology For The Cadastral Systematic Registration In The Republic Of Kosovo
Kosovo Cadastral Agency, Kosovo
Kosovo Cadastral Agency with the continuous support from the World Bank through the project for Real Estate Cadastre and Registration (RECAP) in Kosova, is carrying out the systematic registration activities of reconstruction of cadastral information. This activity consists of public awareness campaign, data collecting from the field, their analyzing and processing until their final registration in Kosovo Cadastre Land Information System (KCLIS).
This pilot project is being implemented in two phases, where the first phase has consisted on production of orthophotos using UAV technology and Open Source Software. This phase has started on December 2015, where for one cadastral zone the process is repeated on April 2016, because of poor weather conditions during the December. The second phase has consisted on data collection from the field through OSS and whole process of reconstruction of cadastral information in about 1,500 ha, in these two cadastral zones is completed by September 15, 2016.
This paper will show results and will give conclusions, recommendations on faster and cheaper collection of geoinformations, from the field, through preliminary signalization of parcel boundaries in the field. All recommendations will facilitate and improve greatly on new projects of reconstruction of cadastral information in the Republic of Kosovo.
