The embodiment of the invention discloses a road planning navigation system capable of automatically generating an investigation map. The system comprises a road environment modeling system, a simulation operation end and a user terminal. The user terminal uses a navigation system in the road environment modeling system to select an investigation route. The simulation operation end performs secondary editing and storage processing on the road environment modeling system according to the survey information. The road environment modeling system comprises a regional geographic database, a GPS navigation system and a GIS geo-science information system. The GIS geo-science information system and the GPS navigation system enable geographic distribution information in the regional geographic database to generate a three-dimensional map, and the GPS navigation system can display the three-dimensional geographic information in a two-dimensional mode. According to the scheme, the survey information is edited and built again in the GIS geology information system, the two-dimensional graph or the three-dimensional graph about the survey information is generated, and therefore manual drawing again is not needed, and errors caused by manual drawing of a survey route are reduced.

The invention relates to a sediment sampler for sampling bottom sediments under the water, in particular to a rotary sealing bottom type superficial layer in-situ sediment sampler. The sediment sampler comprises a sample bailer and is characterized by further comprising a casing pipe, a half cone-shaped underseal, a separation piece, a rotating shaft and a soft spring, wherein the casing pipe is connected with the top of the sample bailer and located on the outer side of the sample bailer, the bottom of the sample bailer is coated by the half cone-shaped underseal, the separation piece is arranged in the sample bailer, the bottom of the rotating shaft is connected with the half cone-shaped underseal, the soft spring is connected with the top of the rotating shaft, the rotating shaft is located in the sample bailer and the casing pipe, and the end portion of the soft spring extends to the outside of the casing pipe to be provided with a rotating handle. The soft spring can be rotated to drive the rotating shaft and the half cone-shaped underseal to rotate, during sampling, firstly the sample bailer is pressed into sediments, then the handle of the soft spring is rotated to enable the half cone-shaped underseal to rotate for 180 degrees to seal a sediment sample, and the sample bailer is lifted to obtain a complete semi-cylindrical sediment sample. The rotary sealing bottom type superficial layer in-situ sediment sampler has the advantages of being simple in operation, high in adaptability and sampling efficiency, small in sediment sample disturbance, convenient to take along and the like, and is particularly suitable for the in-situ accurate sampling of sediment samples of shallow water surface layers.
