SERVER OF GEODETIC AND CARTOGRAPHIC DOCUMENTATION CENTRE

The server of geodetic and cartographic documentation centre ODGIK is a specialized server mean for servicing the contractors performing geodetic and cartographic works. At the moment, execution of geodetic works is connected with having to pay several visits at the centre - first to notify about the work to be performed, then to collect the prepared materials, and finally, when submit the survey made. Should there be any mistakes or defects, noticed when checking the survey, there may be many more visits to pay. The task of the ODGIK server is to eliminate the obligation of paying visits to the documentation centre, or at least to reduce the number of such visits.

The structure of the ODGIK server is similar to the concept of internet mail server. The ODGIK server provides services consisting of data insertion and downloading by two parties.

One of those parties will be the contractors of geodetic works (further referred to as „contractor“), the other party will be the geodetic and cartographic documentation centres, (further referred to as „centre“). Each party has its own data buffer on the ODGIK server. That buffer will be further referred to as „mailbox“.

The contractor is entitled to record in the centre mailbox, as well as to browse/view, read, and delete in its own mailbox. Likewise, the centre is entitled to record in the contractor's mailbox, and to browse/view, read, and delete in its own mailbox. Servicing of the mailboxes is done on the basis of services available on the ODGIK server. The ODGIK server will make use of the server AUTORYZACJA to verify the contractor. Making use of specialized services enables servicing the process of notification, using both the network browsers, and dedicated software, which uses the services directly.

The course of the process of information exchange between the contractor and the centre may be presented in several steps:

1. Contractor notifies the proper centre about geodetic work to be performed, defining its parameters and area extension.
2. The centre collects the notification and carries out initial verification. In case of positive verification, it sends a positive answer, with the KERG number assigned, otherwise it send an error message (reason of refusal).
3. Contractor waits for the confirmation of notification and the KERG number. In case of refusing acceptance of the notification, the contractor has to make corrections in the notification.
4. The centre gathers the data required for the execution of work, and generates recommendations. The recommendations are accompanied by materials in digital form (e.g SWDE, DXF, SHP, or GeoTIFF files) from the area where the work notified about is to be performed, as well as information about the geodetic matrix and the documents possessed in the resource (matrices, sketches, topographic descriptions, etc.) which could be downloaded by means of OSN and OPE services.
5. The contractor collects the recommendations, together with information about materials that can possibly be used, and makes a decision, which data /she wants to download. (The OSN service enables collecting data about matrix points, whereas the OPE service allows to download data from the survey, e.g scans of specific pages of the survey).
6. The contractor executes the geodetic work and prepares the survey (documents), which are sent to the centre (using the traditional method or provided with electronic signature).
7. The centre receives the survey (downloads it if in electronic form) and performs the checking.

1. If the survey (documents, digital data) is correct, the centre accepts it to its resource and duly informs the contractor.
2. If the provided materials are faulty, the centre send to the contractor a report from the checking procedure, demanding correction of faults, (if need be, also the survey is returned).

8. The contractor corrects possible faults and sends explanations, addenda, possibly the entire survey results, to the centre.
9. The centre, after receiving the survey, enters the results of work executed to the system and the geodetic and cartographic resource of the centre.
