The present invention relates to the field of geographic information systems (GIS). The invention presents an apparatus and a method for automatic managing a database (1) of geolocation information and for providing this information to geoinformation systems of for example wireless communication systems. According to the present invention an automatic search agent is provided effecting the following steps for managing the database (1): searching (4) nodes of a network, detecting (13), if geographical position information and associate information of a location is present at the searched node, retrieving the geographical position information and the associated information of the location present at the node of the network, and automatically entering the acquired geographical position information and associated information to the geographic information database (1).

A method of creating conditions which enable assessment of traffic motion rate in a queue of vehicles and enables to construct reference positions for further concatenation of non overlapped segments of mapping sample to further enable more accurate statistical estimates, including either or both average arrival rate of vehicles to the queue and percentage of probes in the queue, wherein according to a predetermined protocol probes report characteristic values of their position to a mapping system which receives and processes the reports, the method comprising: (a) constructing a first mapping sample that includes at least one of said reports, (b) determining a range of said position characteristic values in which at least one of said reports was identified in the first mapping sample, (c) transmitting to reporters a response that according to a predetermined procedure disables transmitters that did not transmit a report within the chosen range of the first mapping sample from continuing to report; and wherein the process of gathering position related updates from probes, associated with the construction of mapping samples, is being made through a dedicated radio channel in which probes transmit signals in pre-assigned slots in accordance with their position and other criteria, determined by a pre determined protocol. 4. A method of determining an indication of length of a queue of vehicles on a road, using probe reports of probes transmitted according to a predetermined protocol, associated with the probe reports, to a mapping system which processes the probe reports, wherein a report includes a characteristic value of position of the probe, the method comprising: (a) constructing with the mapping system a plurality of mapping samples, (b) determining for each of the plurality of mapping samples a position that relates to the farthest probe position from a mapping focus; (c) choosing from the position determined in (b) the position which is the farthest from the mapping focus for determining an indication on length of the queue; wherein the process of gathering position related updates from probes, associated with the construction of mapping samples, is being made through a PLMN or a PDN, which allocates radio communication resources to pre-assigned slots, according to a predetermined protocol associated with the PLMN
