Advancement of technology provides high resolution data for mapping and analysis. Development of Geo Eye / Bird View satellite imageries for urban planning is a common aspects. Now a days the drone survey base high resolution imageries are being developed. The work of level and topographical survey which provides high grade accuracy are being taken up with a digital sensor levels and high resolution total station machines. The establishment of the control points either for drone or TSM survey are being done using DGPS.
Hence therefore, the digital survey provides high grade accuracy for the development of any image and preparing the mapping for any engineering, planning, revenue, architectural projects
