The invention relates to a map scale setting method, a map scale setting device and a terminal and belongs to the field of map displaying. The map scale setting method includes acquiring at least one piece of feature information of a searched target, inputting the feature information of the reached target to a machine learning model to acquire a scale corresponding to the searched target, and determining the scale as the initial scale for displaying a search result of the searched target on a map. With the map scale setting method, the map scale setting device and the terminal, the problem that a map service program is incapable of determining a proper scale for displaying the search result according to actual conditions is solved, and the effect of determining the proper scale according to actual condition of the searched target is achieved.

The invention relates to a method for navigation electronic map pretreatment and display. The method for the navigation electronic map pretreatment and display includes that 1) a system for the navigation electronic map pretreatment and display is arranged, and the system for the navigation electronic map pretreatment and display comprises a computer and a navigator, 2) based on plotting scale information of a navigation software which is used in the navigator, layer index information of all segmentation points under each plotting scale is generated in sequence according to a size sequence of plotting scales, 3) judging if the layer index information of all the rest plotting scales except for a biggest plotting scale is generated in sequence is carried out, 4) layer index files are copied to a catalogue capable of being read by the navigation software of the navigator, 5) when a map is displayed by the navigation software, according to a current plotting scale and a display central point, display road network layers which are optimized are read from the layer index files, and road data which is reasonable in density is achieved and displayed. The method for the navigation electronic map pretreatment and display is capable of being widely used for vehicle navigation.

The invention provides a surrounding hotspot road condition display method. The surrounding hotspot road condition display method is applied to a first client side, and comprises the following steps of: sending a current position and a hotspot road request signal of a user to a server side, so that the server side obtains a peripheral area of the current position of the user, and judges whether a hotspot road exists in the peripheral area or not according to the received current position and the received hotspot road request signal of the user; when the hotspot road exists in the peripheral area, receiving road condition information needing to be displayed returned by the server side according to a hotspot road; and, according to the received road condition information needing to be displayed, automatically and dynamically adjusting a scale map needing to be displayed, so that the map area is displayed. The invention further provides the first client side, the server side and a surrounding hotspot road condition display system. By means of the surrounding hotspot road condition display method, the first client side, the server side and the system provided by the invention, the scale map needing to be displayed can be dynamically adjusted; and thus, the user is rapidly helped to decide a trip route.

The invention discloses a road condition rendering method, device, equipment and medium. The method comprises the following steps: receiving a road condition request sent by a client, and sending theroad condition information used for describing the road condition to the client, so that the client renders the road condition information based on the shape data of the base map. After the embodimentof the invention is adopted, the matching degree of the road condition and the road can be improved.

The invention discloses a method and device for regulating display of a navigation map. The method comprises the steps of: determining a next magnification point; acquiring a vehicle position attribute and road condition information from a current vehicle position to the next magnification point; according to the vehicle position attribute and the road condition information from the current vehicle position to the next magnification point, determining a regulation occasion for a proportional scale of the navigation map; and according to the regulation occasion, regulating the proportional scale of display of the navigation map. By the method disclosed by the invention, the regulation occasion for the proportional scale of the navigation map is determined according to the vehicle position attribute and the real-time road condition information, so that the proportional scale of display of the navigation map is regulated to be fitter with demands of a user and user experience is promoted.

The embodiment of the invention provides a method for adjusting a navigation map scale, and a navigation device. The method comprises the following steps of: acquiring the current position of the navigation device and road condition information from the navigation device to a destination; setting a path selection point to be displayed by a navigation map of the navigation device according to the acquired road condition information, wherein the path selection point comprises any one or more of a corner point, a lane, a traffic light, a one-way street, a traffic limiting street, a crowded street and a traffic control street; and displaying the road condition information between the navigation device and the path selection point on the navigation map at a proper scale according to the set path selection point and the scale of the navigation map on the navigation device at the current position of a vehicle. By implementing the method, the navigation map of the navigation device is automatically adjusted according to user demand and inflexibility of manual operation of a user is avoided.
