Abstract

Research topic: "Application of images from UAV (Unmanned Aerial Vehicle) to create a 1: 2000 cadastral map in Hoa Khanh Tay commune-Duc Hoa district-Long An province". The project was conducted in Hoa Khanh Tay commune, Duc Hoa district, Long An province from August 2017 to December 2018 with the goal of testing the establishment of 1: 2000 cadastral map from UAV images, with Trimble UX5 HP aircraft and SONY a7R camera; The purpose of the paper is to assess the accuracy when using digital images taken from UAV to create large scale cadastral maps for state management of land. The project carried out through steps: designing flight imagegraphy, measuring grid control coordinates by static GPS technology, processing images, digitizing, drawing pictures, surveying information and additional measurements by total stationary method in the field, editing and perfecting the cadastral map according to current regulations. Based on the results of the project: evaluation of the accuracy and applicability of UAV images in mapping.
