Description

The invention relates to geographic information systems, in particular to systems for generating a graphical user interface with functions for inputting, displaying and modifying spatial data on computing devices equipped with a display and a mouse or touch screen data input device.

In the modern world, a person daily generates a significant amount of heterogeneous information that needs to be analyzed. Having access to the accumulated text, graphic, video, geodata, another task arises - presenting the results to an end user who is not an expert in the field of big data analysis, cartography, or geographic information systems. The analysis of spatial data requires knowledge of the query or programming language, the creation of a simple representation in any well-known geographic information system requires an understanding of the principles of the operation of map services, manual connection of the required data sources, and skills in working with database tools by which the relevant entities are connected and the necessary attribute information is displayed . This approach does not involve automation of the process of preparing heterogeneous data for analysis and visualization, which ultimately reduces the efficiency of using the accumulated spatial data.

Known methods for visualizing geographic data based on color palettes, for example, a height scale or heat map; point cloud allows you to visualize areas with a high population density, display the intensity of Internet traffic; clustering can increase the visibility of data depending on the map scale and prevent the intersection of a large number of closely spaced elements, and when used together with a color scale, visualize another parameter based on it; cartograms allow you to link a geospatial parameter (for example, the area of the country) to the analyzed value (population) and display a slightly distorted map, but provided that the geographic data are unimportant for this case or can be neglected.

To increase productivity, they use the splitting of raster and vector images into a large number of small images (that is, building a pyramid of scales), which underlies all mapping services.

Implementations of such technical solutions are described in US 20050091223 A1 (IPC G06F 7/00, Kevin B. Shaw, Miyi J. Chung, Maria A. Cobb, 04/28/2005). It proposes an object-oriented system for creating and storing a spatial data structure for use in multi-tier applications. The data is organized into a database that contains the coordinates of geospatial objects, attributes, and metadata in a hierarchical relational structure. The system provides for the creation of objects and levels that make up the database, and spatial indexing of data between objects by hierarchy levels. Data can be updated and exported to vector formats of relational databases.

In the patent US 20110316854 A1 (IPC G06T 17/00, Bryan Vandrovec, December 29, 2011), a process for optimizing layer detail at different scales is described, which consists in lowering the degree of discretization of the height grid to the minimum allowable distinguishable value. In accordance with the level of detail parameter, a new layer-scale pyramid is built. This approach allows you to increase the performance of the geographic information system, reduce the minimum level of RAM on the client PC.

US20130321456 A1 (IPC G09G 5/00, G06F 3/041, Jeffrey P. Hultquist, James A. Howard, Aroon Pahwa, Christopher Blumenberg, December 5, 2013) describes methods, systems, and apparatus for displaying a multi-layer card. A map consisting of geographic data of raster and vector formats can be generated by a map service and sent to a client device. The client device can receive input by changing the zoom level of the displayed map. Some implementation options allow you to receive updated data from a client in a raster format.

In the application for invention US 2014/0047409 A1 (IPC G06F 9/44 (2006.01), Edward Yang, Robyn J. Chan, Hanju Kim, 02/13/2014), which is selected as a prototype, describes a system and device that implements a means of developing corporate applications. The application development system includes a user interface that allows the user to select and change widgets, display the properties of the application program interface on the attributes of the widget, and also create user interfaces for applications using widgets. To change widgets and create applications, the system can change the source code associated with the widget or application based on data received from the user through the interface of the application development system.

The disadvantage of these analogues and prototype is the significant time spent by the user on configuring the electronic atlas with spatial vector data from various sources by generating data for the electronic atlas and applying input, editing, selection, connection, aggregation, filtering, sorting operations to them, which reduces the quality making decisions based on the results.

The technical result of the proposed system is to reduce the operator’s time spent on configuring an electronic atlas with spatial vector data from various sources by generating data for the electronic atlas and applying input, editing, selection, connection, aggregation, filtering, and sorting operations to them.

The listed new set of essential features provides the ability to generate program code for the functional parts of the user interface that implements the input / output functions for the user-defined sets of elements from the final set of vector spatial data that allows to achieve the claimed technical result.

The analysis of the prior art made it possible to establish that analogues that are characterized by a combination of features that are identical to all the features of the claimed technical solution are absent, which indicates compliance of the invention with the condition of patentability "novelty".

Therefore, the claimed invention meets the condition of patentability "inventive step".

FIG. 3. - A visual representation of the spatial query designer in the original user interface.

FIG. 4. - Visual representation of a new set of spatial data and current elements in the created user interface.

Carry out the invention as follows.

In FIG. 1 shows an embodiment of a computing system with a set of blocks and devices that can be used to perform the above processes. The system includes: an input / output unit, one or more central processors, and a memory unit. The input / output unit is connected to a display, a keyboard, a mouse-type pointing device, a data storage device, and a multimedia storage unit. The multimedia disc unit can read / write machine-readable media that contains program and / or data.

At the first stage, from the data storage device with the database of vector spatial data, data on the requested sample is read and written to the metadata storage unit about the initial vector spatial data (block 1, Fig. 2).

At the second stage, the spatial query designer is called (Fig. 3), and for each set of elements (fields) of the initial set of vector spatial data included in the created query, one or more spatial unary logical operations (spatial functions) are set, and / or for the set ( several sets) of two sets of elements (fields) of vector spatial data define one or more spatial binary logical operations (spatial functions), and / or for a set (several sets) of one set of elements (fields) of vector spatial data and a user spatial element define one or more spatial binary logical operations (spatial functions), on the basis of which the program code of the functional parts of the new user interface is generated: data models of an object-relational projector, visual representation of spatial data and the controller according to the architecture of the MVC application: “Model” - “Presentation” - “Controller” (blocks 2-16, FIG. 2).

At the third stage, the user, using the created interface (Fig. 4), carries out, if necessary, actions for entering, selecting, aggregating, filtering, sorting and viewing elements of ordinary and vector spatial data and visualizing the final set of elements on the screen in a tabular form with a map display current items.

The implementation of the claimed invention is explained as follows.

The metadata storage unit for the source vector spatial data, the intermediate data storage unit, the metadata storage unit for the output vector spatial data can be implemented on the basis of computer-readable media - random access memory (Veniaminov V.N. et al. Chips and their application: Reference manual. - M .: Radio and communications, 1989. - 240 p., Pages 145-152).

The control unit for processing the set of initial vectorial spatial data, the unit for generating program code for the functional parts of the user interface can be implemented on the basis of computing devices - microprocessors controlled by a program written on a machine-readable medium (Veniaminov V.N. et al. Chips and their application: Reference manual . - M .: Radio and communications, 1989. - 240 p., Pages 161-167).

The vector spatial data display unit may contain a monitor, and for manual work of the user with data, use a mouse input device or a touch screen (V. Broydo, O. Ilyina. Computer and system architecture. - St. Petersburg: Peter , 2009 .-- 720 p., Pages 245-278).

Vector spatial data is stored on a data storage device, which can be implemented on the basis of a computer-readable medium of large capacity, reading and writing to which is carried out under the control of an input / output unit (V. Broydo, O. Ilyina. Computer and system architecture. - St. Petersburg: Peter, 2009 .-- 720 p., Pages 218-220).

"Industrial applicability" of the invention is due to the presence of the element base, on the basis of which actions can be performed that implement this system to achieve the destination specified in the invention.

The implementation of the system is carried out using the created programs, which can be included in the package of application programs on the principle of nesting the modules into each other and function in both self-sequential and parallel execution mode.

The architectural templates of applications that have appeared in recent years, object-relational projectors, and development automation methods make it possible to apply their capabilities when working with spatial data, when any task always implies the implementation of new functionality. So, each point of a spatial object is characterized by coordinates. The features themselves are a point, line, polyline, polygon (closed polyline), or a collection of the listed geometries. Spatial functions (logical operations according to this description) involve the operations of calculating the intersection areas of vector spatial objects, combining them, finding the area of the object, its length, perimeter, neighborhood of a certain radius, and the like. The object-relational projector allows you to create a metadata query about the fields of the new sample and the data itself from the database of vector spatial data in the language of queries to the data storage device. In accordance with the architectural template, the generation of the code of the application elements and user interface is a formalized task, since its components are strictly structured and standardized. Accordingly, the "Model" is consistent with the storage structure of spatial and ordinary data. The "controller" controls the process of calling the "Model" and returning data from it to the user interface ("View"). The proposed system allows you to simplify the work with spatial data and get the necessary functionality in a few minutes. Once requesting a selection with spatial data types and creating an interface, it becomes available to other users (if they have rights to it).

The proposed system forms an intuitive user interface for displaying operator-defined sets of elements from a set of vector spatial data with the possibility of setting the spatial function applied to the original sets of elements and / or a given user spatial element, conditions for filtering and sorting the set of output spatial elements and visualizing them on electronic atlas based on user interface generated by generating code of its functional parts. The system also provides an opportunity to modify the selected spatial data element from the user interface by adjusting it on the map using a mouse input device or a touch screen, and then save the changes to the data storage device.

The advantage of this approach is confirmed experimentally by comparing the time spent on the formation of a test configuration of the electronic atlas with the ArcGIS geographic information system.

So, the time spent writing and debugging in "ArcGIS" an SQL query with spatial functions for a DBMS by an experienced user in manual mode is 15 minutes, the time to add a layer with vector data is 5 minutes.

In the case of using the capabilities of the developed system, the operator spends 5 minutes creating a view with spatial functions through the user interface of the system and generating a new interface based on it. Therefore, the proposed system saves the user from manually writing queries to select spatial data or attracting a programmer, which saves from 15 minutes of work for each unique task.

Thus, the proposed system reduces the operator’s time spent on configuring the electronic atlas with spatial vector data from various sources by generating data for the electronic atlas and applying input, editing, selection, connection, aggregation, filtering, and sorting operations to them.
