There are no electronic covers which are designed for land work professionals, which have the characteristics of the electronic land work tablet cover and which can be integrated with on-site measuring devices

SUBSTITUTE SHEETS (RULE 26) and an on-site tablet.

The control units in the market which are used together with land work measuring devices are used solely for the purpose of importing data and only the most basic functions can be carried out in terms of data processing; however, said units are not customized to obtain the final product. They do not possess critical characteristics such as the sufficient screen size, screen sensitivity and magnetic pen, which are required for obtaining the final product. Furthermore, they do not meet ergonomic requirements and they are not electronic covers; rather, they are devices with mobile computer circuits which operate as a whole with its own case.

There is no mobile digital platform in the field which is customized to draw on and which can communicate with land measuring devices. Nowadays, the data acquired from the measuring devices in the field of land works can be processed on paper, as was the case in the past. The drawings and reports obtained by processing the data on paper are archived by being scanned in high resolution in the office environment and the drawings are digitally redone in the office environment. Technical problems the invention aims to solve

In conventional documentation systems, in cases where measuring is performed on-site and data processing is performed in the office, problems in terms of obtaining the final product due to incomplete data recording; the requirement for scanning and digitally reconstructing drawings in the office in cases where measuring is performed on site and technical drawing is performed on paper on site; and the requirement for compiling the information and documents drawn paper on site or during the storage of used technological devices, and adapting said information and documents to the digital reporting and documentation system are time consuming efforts which are costly, which do not utilize technology efficiently and which cause the quality of the final product to be low. The system of the present invention solves the aforementioned technical problems by the integration of the electronic cover invention to land works.
