Description

Visualization method for acquiring real estate information through frame selection map Technical Field The invention belongs to the technical field of visualization, and particularly relates to a visualization method for acquiring real estate information through a frame selection map. Background Most real estate websites are leased or purchased, the selection area is a text matching search or drop-down frame selection area, the operation is inconvenient and the experience is not good, the selection of the area is carried out in a mode of determining city-urban area-street each time, and the real estate information in the area is obtained on the basis of the boundary of the area, and the defects of the mode are that: 1) Inconvenient and inconvenient The method needs to know the wanted area, if the user only knows that the price of a certain area is proper, but only can see the specific information of the cell during selection, the area and the position of the area cannot be intuitively seen from the map, if the user does not know the area, misjudgment easily occurs, and the information searching time is increased. 2) Not efficient The number of the floors in one city is not good, the old floors are good, the new floors are good, the old floors are good, the new floors are the price which is one from one point, and the new floors are not two points selected by a user, for example, the range of the radius 5m around a working place can be determined, but the area can be determined only in the prior art, the user searches for information needed by the user in massive information through the determined area, and the information of the floors needed by the user in the areas cannot be visually checked from a map. 3) Poor experience It can be further understood from the above that the conventional manner is not experienced well, referring to fig. 7, the search result shown in the figure is the result obtained by the conventional text matching search or the drop-down box selection area, but in fact, if a certain area is not familiar with it, a specific point is needed to be taken into the matching of the map view periphery of the cell, although the prior art can also obtain the corresponding information through the cell name search, the manner is not the manner of searching the cell but the manner of searching the cell for the cell, the experience is not good, and most commonly, the search is completed to a proper re-point to the view position, and so on, which is quite time-consuming. The applicant has therefore proposed a visualization method which solves the above-mentioned drawbacks, the visualization (Visualization) being a theory, a method and a technique for converting data into graphics or images to be displayed on a screen, and then performing interactive processing, using computer graphics and image processing techniques. And a map interception function application based on visual operation in the real estate network by utilizing the visual application. In the prior art, a map house searching technology is also used, such as a resident map house searching technology, the user can look up the cell information of a required area through the map, but the user still needs to confirm the area or enlarge the map, and the user can look up the required information from the map step by step. Disclosure of Invention Technical scheme (one) The invention is realized by the following technical scheme that the visualized method for acquiring the property information through the frame selection map comprises the following steps: The server receives the first query condition and judges whether a map meeting the first query condition exists or not; If no return non-queried instruction exists; If yes, accessing a map meeting the first query condition to perform gridding processing; generating a drawing interface to draw a graph on the gridded map; Forming a boundary instruction based on the drawing graph and transmitting the boundary instruction to a server; Judging whether a query result meeting the boundary instruction exists in the server or not; If not, returning an unoccupied instruction; and if the query result data exist, extracting the query result data for visualization processing. As a further illustration of the above, the method further comprises: sending a boundary condition modification instruction to generate a drawing interface; Forming a boundary instruction based on the drawing graph and transmitting the boundary instruction to a server; The server judges whether a query result meeting the boundary instruction exists; If not, returning an unoccupied instruction; and if the query result data exist, extracting the query result data for visualization processing. As a further illustration of the above, the method further comprises: the visualization processing result is fed back to the gridding map, and the server receives a second query instruction; Judging whether the visual result of the second query instruc
