Description

Error compensation method digital map using matching with output draft}

The present invention relates to a technique for producing a digital map, and more particularly, to a method for correcting an error of a digital map by using matching between a drawing displayed through a transparent touch screen and an output drawing modified through field inspection.

In general, a digital map is a computerized drawing process based on the secured aerial photographing image, and then computed a map made in the form of paper completed by the drawing work by indicating the position and shape of the terrain, features and names as coordinate data. This means that digital maps are created by displaying them in a digital format that can be processed and interpreting and editing numerically various topographical data.

In the process of constructing the old digital map, first, the paper map is digitized or scanned to generate a digital map, and then the coordinates are converted to the actual map to meet the user's purpose. Convert to Thereafter, this is done by inputting the attribute data into a numerical map that establishes a topological structure to grasp the inter-location and correlation between spatial objects. At this time, the attribute data includes various identifier information. As an example, a unique feature identifier (UFID) is used as an identifier for a feature of a digital map of the National Geographic Information Institute. This is a single identifier that indicates the location information, management authority, and other attribute information that is given to the feature. It is the unique identifier of the feature, and consists of an organization code, leaf number, feature identification code, and serial number field. It is used as an identifier for linking with other geographic information or cross-referencing between features for management, retrieval and utilization of features.

However, the drawing is performed based on aerial photographs taken by aerial photographs and satellite images, and the aerial photographs are plane images of the ground photographed by aerial photographs. There is a difference between the appearance and the difference, which makes it difficult to guarantee the accuracy of the feature of the drawing. Accordingly, a problem arises that it is difficult to guarantee the accuracy of the attribute data assigned to each feature.

For this reason, digital map makers are making digital maps by correcting errors in drawing through field surveys to ensure the accuracy of digital maps.

1 is a flowchart illustrating a conventional digital map production process.

Referring to FIG. 1, a digital map maker prints a drawing generated through digitizing or scanning such as surveying maps, aerial photographs, and satellite images on paper (S10), and corresponding regions of the printed drawings. Perform a site survey to (S20).

At this time, in the field survey, various artificial features and natural terrain such as buildings, roads (paved, unpaved), railroads, parks, rivers, mountains, rice fields, and fields indicated in drawings printed on actual places actually exist, or actual places Check whether the size, direction, and shape of the artificial features and natural topography that are located in the drawings are correctly displayed in the drawing, and if there are other parts, modify them manually in the drawing. In addition, attribute data such as the name of the artificial feature and the natural topography, name, and basic information (the number of floors of the building, the width of the road or the river, etc.) are manually indicated at the corresponding position in the drawing.

When the marking of the artificial features and natural topography that are incorrectly depicted in the drawing and the attribute data of each artificial feature and the natural topography through the field survey is completed, the above-mentioned drawing is manually generated by computerization. By modifying and supplementing the drawing and map input performances by displaying the change information, an exact position editing to grasp the geographical correlation of the terrain and the feature is performed (S30).

Subsequently, after establishing the geometric structure of the points, lines, and surfaces defined by the Geographic Information Institute, the terrain and features edited through the in-situ editing, and then manually inspect the incorrect attribute information of each artificial feature and natural terrain surveyed through field survey. Perform structured editing to edit (S40). At this time, in the structured editing, the attribute data of which only points, lines, and surfaces are displayed in the drawing is edited in a hidden state (not stored on the screen).

When the structured editing is completed as described above, the digital map is produced and printed using a software program provided by the National Geographic Information Institute and provided to the National Geographic Information Institute requesting the digital map production (S50). In this case, the software program is a program for changing the structured and edited data into a defined form, which generally uses a known program provided by the National Geographic Information Institute.
