Embodiment Construction

[0013] The invention uses the GIS graphic file as the template of the histogram of the geological exploration drilling, and realizes a set of function codes to deal with the changeable histogram schema. The method is: the graphic file in GIS format contains both spatial data and attribute data. Based on this feature, a fixed code is assigned to the primitive in the histogram, and the code is stored in the corresponding attribute structure of the primitive. The mapping system By retrieving these codes, the contents and positions of the primitives to be displayed in the histogram are obtained, and then the specific values ​​of the primitives are set to achieve different histogram formats.

[0014] Specifically include the following steps:

[0015] 1. Formulate coding rules: collect and sort out the possible expression content of the geological exploration borehole histogram, and formulate a unique code for each item to facilitate identification by the mapping system, as shown in...

Abstract

Method for composite drawing histogram of geologic examination is as following: graphics file in GIS format includes spatial data and attribute data in same time; based on the said point, fixed code is assigned to primitive in histogram, and code is placed to attribute structure relevant to primitive; through searching codes, cartography system obtains content of primitive and location to be represented on histogram; then setting up specific value for primitive in order to realize different formats of histogram. Since the method assigns and saves specific value for relevant primitive in histogram, the cartography software can obtain represented content and location of histogram through codes so that function code and drawings formats in cartography module can be separated. The invention possesses portability and reusability of software. Moreover, using editing environment for GIS primitive conveniently, user can adjust format of histogram visually.

Description

technical field [0001] The present invention relates to the computer arrangement of achievement data in the field of geological prospecting (including regional geological survey, mineral prospecting, hydrogeological survey, engineering geological survey, disaster geological survey, etc.). Background technique [0002] In geological exploration work, it is necessary to compile a large number of borehole histograms. At present, this work has been generally implemented by computer, and the histogram compilation software (or system) has been used to realize the automation of the drawing process. However, due to differences in industry requirements and normative standards between construction units and management units, there are different requirements for the format of histograms, and it is necessary for the histogram compilation system to be able to adapt and draw histograms with rich formats. [0003] Most of the histogram editing software (or systems) currently in use are for...
