[0002] With the exploration and practice of applied geological work, the cross-integration characteristics of applied geological work and various fields are becoming increasingly obvious. A large amount of multi-source heterogeneous data from various fields has poured into applied geological work. The idea of ​​applied geological work needs to change from single-type data survey to multi-source data survey. In the process of applied geological work, it is necessary to consider the storage, call, fusion, display, and evaluation of multi-source heterogeneous data including geological information, hydrological information, geological disaster information, geophysical field information, mineral information, remote sensing information, forestry information, traffic information, and surveying and mapping information. However, the use of applied geological information has problems such as difficulty in integrating multi-source heterogeneous data, low efficiency in applied geological information collection, difficulty in displaying applied geological products, and difficulty in intercommunication of applied geological data from different units. In addition, there are many factors that affect data application, which are restricted by data type, scale, scale, format, and mapping software or basic geographic information system software platform. The existing software platform design is difficult to meet actual needs, and the problem of developing software matching applied geological survey work needs to be solved urgently.

Click the element query function, stop the mouse at a point in the view, and the mouse will display the brief information of the element at the point. If the point contains multiple elements, they will be displayed separately. Click the mouse to pop up a detailed attribute list. If it contains multiple elements, click the mouse to pop up a dialog box to display which elements are included. You can view the attributes of a certain element by selecting it.

[0006] Step 2: Click anywhere in the view with the left button of the mouse, and the system will automatically query all feature information within a 50-meter range with the point as the center, and display it in the dialog box. The element OID dialog box will display brief information about the feature;

[0007] Step 3: Click any element in the OID of the graphic element to display all the information of the point in the dialog box below. At the bottom, there is a brief explanation of the point, and field photos and record tables of the point are provided. When the mouse is placed on the photo or record table, it will be enlarged in the view;

[0008] Step 4: Double-clicking any element in the graphic element OID will flash the position and boundary of the point in the view to perform the graphic attribute linkage function.

[0009] Preferably, in step one, the attributes of the graphic element include attribute information, military explanations, photos, and record tables, etc. The attribute information includes its military analysis, photos, and table information, etc. It is necessary to establish an object class data set of the spatial database to call and display the classified object data set.

[0010] Preferably, the classification query method is:

[0011] Step 1: Select all sub-maps that provide a single element for attribute query, input data through the data import function, and establish a spatial database organized with different types of survey points as the basic data source for classification query and display;

[0012] Step 2: Display and summarize the relevant attributes and other information according to different types of survey data;

[0013] Step 3: In the data classification selection, select the data classification you want to view, and the system will automatically close other layers of the same nature in the view. For example, if the survey point is selected as rock mass, all the points seen in the view are rock mass survey points, and other point files will be closed.

[0014] Preferably, in step one, the selected elements include rock survey points, soil survey points, resource survey points, well survey points, spring survey points, river survey points, collapse survey points, subsidence survey points, landslide survey points, debris flow survey points, tectonic lines, soil survey areas, rock survey areas, water survey areas and transportation facilities.

The present invention, this query display method takes into account the characteristics of applied geological data, extracts and displays applied geological data, and is faster and more effective than traditional data display methods. This query display method is based on GIS maps for map display, adds data location information, and is more intuitive and clear than traditional data display methods.

[0017] 2. The present invention, based on GIS data query, divides different types of applied geological data into point elements, line elements and surface elements for query, and provides all sub-graph attribute queries of a single element. Through the above two methods, all applied geological element information can be fully and reasonably displayed. BRIEF DESCRIPTION OF THE DRAWINGS
