DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method for visualizing geological information and a method for providing geological information according to the present invention will be described in detail with reference to the drawings. The database used in these methods is data obtained by a boring survey conducted at a predetermined place and a predetermined depth in advance, for example, geology,
It consists of a data group in which data representing information on the presence / absence of groundwater, electric properties, presence / absence of seismic waves, temperature, presence / absence of gas, etc. is accumulated for each measurement point represented by three-dimensional coordinates.

The geological survey for obtaining the data for constructing the above-mentioned database includes the geology such as the presence or absence of bedrock, the presence or absence of groundwater and, if necessary, the chemical composition of groundwater, and the presence or absence of gas and if necessary. Although it is not particularly limited as long as it is a method usually performed for investigating the composition of a gas or the like, an investigation conducted using a boring machine (hereinafter, referred to as “boring investigation”) is preferable.

In the boring survey, as shown in FIG. 1, first, a boring 110 having a depth D is hit at an arbitrary position on the land 100. At this time, what kind of geology, what kind of geology, whether there is groundwater, and whether there is gas at a depth of several meters to several meters is dug and checked, and recorded as described later. Here, “geology” refers to the state of a bedrock layer, a clay layer, a topsoil layer, a sand layer, a basement layer, and the like.

If there is groundwater, the groundwater is taken out and the chemical components contained in the water are analyzed. Similarly, if there is a gas, the gas is taken out and the chemical composition contained in the gas is taken out. Perform an analysis. Conventional methods are used for this analysis. Such a boring survey is performed at a predetermined distance L, and data obtained by each boring 110 is recorded as described later.

Further, as shown in FIG. 2, the sensors 120 are arranged at predetermined intervals D1 in the boring 110 and at predetermined intervals L1 on the ground surface. This sensor 120 can detect vibration generated by the oscillator 130 arranged at a predetermined place, for example, by arranging electrodes together with each sensor 120, and detecting the state of conduction between the electrodes,
Further, a temperature in the vicinity is detected.

In the vibration detection, one oscillator 130 is operated, and the vibration detected by all the sensors 120 is recorded.
From this result, the seismic wave velocity is calculated, and the seismic wave velocity at each point is recorded as described later. To detect the energized state, select any pair of electrodes, energize between these electrodes, calculate the specific resistance as an electrical property from the detected result, and record this value as described later. Keep it.

From these physical properties, an index such as the geology between the sensors 120, for example, hardness, the presence or absence of groundwater, and the like can be obtained. In addition, it is preferable from the viewpoint of data handling that one data group is configured using the data in the following table format, and the data of each item is associated with each other.

[0027]

[Table 1]

In this table, the position is represented by latitude,
Although indicated by longitude and depth, they may be indicated by relative coordinates for specifying a certain position. Regarding the presence or absence of groundwater, “0” indicates no state and “1” indicates a certain state. Therefore, the table shows the state of "there is groundwater". The geology is
It is preferable that A is represented by a bedrock layer and B is represented by a clay layer, for example, from the viewpoint of reducing the amount of accumulated data.

When groundwater is contained, a separate table is provided for the chemical composition contained in the groundwater with chemical formulas or names such as Na, S, Cl, and trihalomethane. Or if it is known as a candidate containing a predetermined chemical substance, these substances are registered as master data as shown in the table below, and for each candidate, “include (1)”, It may be indicated by expressing “not included (0)”.

[0030]

[Table 2]

The chemical composition of the gas containing the gas is also recorded in the same manner as described above. These chemical composition data may be associated with each of the position data represented by latitude, longitude, and depth, or may be associated with each of groundwater and gas that exist or are assumed to exist in a certain range. Good. In the latter case, data indicating a range for specifying the corresponding groundwater or gas is also registered in association with the data.

By constructing such a database, it is possible to simply specify a desired place with predetermined coordinates,
It is possible to extract geological information associated with the coordinates. In addition, it is preferable to further relate the measurement date and time to these data. In this way, it is possible to extract the current geological information and the data indicating the geological information at one point in the past, such as the geological information one year ago, at the same place. By performing visualization described later using these data, it is possible to obtain an image representing a temporal change of geology from the viewpoint of, for example, environmental conservation.

Further, by using a map as a coordinate for specifying a range, a point on the map is designated by an appropriate pointer or the like, thereby specifying the latitude and longitude of this position, and further depth by hand. You may enter it. In this way, by specifying one point on the map, instead of inputting data for specifying a place, it is easy to specify the area range and the range can be specified while looking at the map. Can be specified exactly.

At this time, the order of inputting the coordinates is not important, but for example, first, input a range on a plane,
Next, the depth may be input. Also, display the map,
The same can be performed by specifying any two points on the map, specifying the position on the plane, and inputting the depth separately. In this way, by displaying the map and inputting it on the map, the input operation is simplified, and even when accurate position data (latitude, longitude, etc.) is not known, a desired position can be determined.

If, for example, information on seismic wave velocity is selected from the extracted data group using data on the type of information as a keyword, data on seismic wave velocity is extracted.

Here, the range determined according to the type of the image is shown in FIG. 4 so that when a vertical sectional view is desired, a vertical sectional view can be created in an image creation step (step S30) described later. As shown, the starting point (latitude x1, longitude y
1), end point (latitude x2, longitude y2), depth z1 to z2, if specified in step S10, point A (x1, y1, z1), point B (x2, y2, z1), point C (X1, y1, z2), point D (x2, y
The outer edge of the quadrilateral having the vertex of 2, 2, z2) and the inside thereof, and the extracted data group is a data group at a position falling within this range.

When the timing is specified in step S10, a data group corresponding to the timing is extracted.
For example, if it is designated as 1990, the position,
A data group having data of 1990 is extracted in addition to the type of information and the type of image. Step S3
At 0, an image corresponding to the type of image specified in step S10 is created using the extracted data.

This image is an image showing a place where the layer changes as a contour line, and the contour line is a curve obtained by simulating data existing at points near the place where the layer changes. is there. This simulation uses an appropriate approximation method such as a non-linear least squares method for approximating a line from a set of points. In step S40, the image created in step S30 is output to an appropriate output unit, for example, a display, a printer, or the like.
