1. INTRODUCTION
Nowadays IT are involved in( almost) every activity of the human life, including the geodetic profession. Depending on the specific task in geodesy the percentage of the usage of IT may vary.
The implementation of the IT in geodesy is not only used directly for the completion of the task, but it simplifies the way we share the information with other colleagues and finally keep the data safe – create a backup. The ways how the IT could be implemented nowadays in geodesy was described in a number of papers [ 7 ], [ 2 ], [ 5 ] and others.
The possible usage of the modern technologies in geodesy was descried in several papers. e. g.; [ 9 ], [ 10 ]. Papers or topics, dealing with Nextcloud, geodesy and IT could not be found.
In general, today’ s geodetic activities consist of: field measurements( using the relevant equipment), transfer of the data( results) from the internal memory / flash card to the cloud via Internet and last but not least their fast and safe management in the server.
The aim of this paper is to show one specific application of the IT in geodesy, which was applied for storage, management, sharing and backup of data – in our specific case geodetic measurements and their results. Here, Nextcloud was involved, as“ Open source content collaboration platform”.
The reasons to use this platform were not limited to:
-convenient to use;-open source;-self hosted;-regular updates available;-beta and stable versions;-secure;-others.
This paper studies in details the technical implementation of the following key parts of the geodetic activities:
-check the availability of Internet at the area of performing of GNSS measurements;-control of the work of the controller( under OS Android)-data transfer in the cloud;-data processing and backup;-sharing the results with others, when required.
2. CONTEMPORARY GEODETIC INSTRUMENTS – REQUIREMENTS AND RELEVANT DATA MANAGEMENT
Depending on the object to be measured, the geodesist must decide what type of equipment and technology, or several of them to choose from for performing the field work. The instrument / s / could be e. g. GNSS rover, 3D terrestrial laser scanner, drone, total station, etc. One of the common points of the various geodetic instruments is the data storage and its relevant management. Regardless of the way, the instrument collects and stores data. A key moment of the geodetic work is its export( in the cloud) for further processing, analysis and backup.
Here will be given some of the requirements for the GNSS system and 3D terrestrial laser scanner. Similar examples could be given for the other surveying instruments. a) GNSS rover-Internet is required;-ensured in advance its connectivity with Internet at the region of measurements;-in case of lack of cell phone coverage – possible access to satellite Internet. b) 3D terrestrial laser scanner:-spherical / flat targets are required for( fast) station combination and georeferencing;-choosing of appropriate places for the targets( height, distance, etc.);-mutual geometry of the targets and visibility scanner-targets.
