According to the invention, the change condition of land resource information within a time span can be expressed, the change rule of the land resource can be analyzed and predicted, and thus, the historical data management problem of the geographical information system can be solved well.

Description

The time management method of a kind of soil information

Technical field

The present invention relates to information management, relate in particular to the time management method of soil information.

Background technology

Geographic Information System is a kind of collection, storage, management, analysis and expression of space data computing machine system of being specifically designed to.It is expression, the world, simulating reality space and the instrument that carries out the spatial data Treatment Analysis, also is " science and technology " about the spatial information Treatment Analysis, can also can be regarded as people are used to solve the resource of space problem simultaneously.Land information system is the Geographic Information System that comprises the soil data, be in the land management process to the application of Geographic Information System hi-tech, be the important means in qualitative, quantitative, location and visual research soil.

Soil information had both comprised spatial information, comprised attribute information again, and the spatial information and the attribute information in soil constantly change in time.The soil is as natural resources, human transformation activity and the displacement transition that all can bring its natural form to it; The soil is as assets, and in socio-economic activity, its spatial shape and attribute can be because reasons such as the cutting apart of soil, merging, purposes variation change.In recent decades, it is swift and violent to be accompanied by the urbanization Rapid Expansion, and the soil is obviously in short supply as non-renewable resources, and the city state-owned land is accompanied by socio-economic development, changes frequent day by day.At this moment, relevant unit is in order rationally to utilize land resource, and to the demand surge of soil information, the requirement of soil information being carried out advanced treating also improves constantly.

The soil has produced the historical data of magnanimity as resource and assets in constantly changing.The processing of mass data has proposed new requirement to geographical information technology.In one's early years, the development restriction of computer software and hardware and cost performance problem have limited the reservation of historical data, and therefore traditional Database Systems majority is just stored current data.In the recent period, though hardware condition allows,, therefore be difficult to realize the function of the situation of change of display space entity in a period of time equally owing to lack comparatively perfect historical data management mode.In work of land management, all kinds of historical datas especially soil are utilized the inquiry of historical data more and more frequent with retrieval, data management has proposed the high request that space-time data is managed to work of land management person to the soil.

Summary of the invention

The objective of the invention is to solve the high request of in the work of land management soil space-time data being managed.

General land use planning system all can realize functions such as data acquisition, management, processing, inquiry, editor, demonstration, drawing, conversion, analysis and output.The present invention mainly pays close attention to is time management function in the land use planning system, and by concrete experiment realize to the key element of the trend of the times and historical data obtain, functions such as version derivation, version submission.

The present invention is achieved in that

In the 1st step, system environments is prepared and primary data imports;

In the 2nd step, design detailed experiment content according to space-time model Data Structure Design, modelling restriction and version designing requirement;

In the 3rd step,, in experiment, finish the space-time management of data according to the version management content;

The 4th step, the compile script statement, the basic function of integration GIS platform utilizes experimental data, realizes the application scenarios in the real work, and intuitively shows achievement.

Of the present invention possess the tense analytic function, can rationally express the situation of change of land resource information in certain time span, can analyze and predict the Changing Pattern of land resource reasonably and accurately.Thereby can solve the historical data management problem of Geographic Information System well.

Accompanying drawing is a journey process flow diagram of the present invention.

Embodiment

Below the present invention is done concrete case study on implementation introduction:

At first, system is prepared.1., set up new project file this process was divided into for three steps:; 2., prepare primary data; 3., add the time management field.

An important part was exactly that data are introduced during primary data was prepared, and for integrality, accuracy and the historical consistance that guarantees data, will control the history of legacy data simultaneously to georeferencing, spatial dimension, geometric type inspection when importing data.

Realize the space-time management function in the land use planning system, a main application is that version key element and old version key element are obtained in success, and present embodiment will be realized this function in special scenes.Successful realization that it should be noted that the space-time management function must be based upon on the basis of problems such as effectively handling version is created and edited, conflict mediation well.

As shown in the figure, first, second, the third three people all have the authority of upgrading trend of the times storehouse.But because trend of the times version is the root of version tree, therefore three people all must not directly edit trend of the times version, can only upgrade trend of the times version by the submission of descendants's version.They successively derive version three versions, editing and processing separately successively by trend of the times version V0.After editing and processing after a while, three people submit to trend of the times storehouse at different time, and submit to version to solve by the back and submit collision problem to.

Show in Geographic Information System land use planning system for function, need in the Geographic Information System environment, carry out writing of script sentence, realize selecting to such an extent that load atural object, intuitively embody the space-time management function practical operation.Relate to database section in the space-time management function exploitation of Geographic Information System land use planning system and will use SQL statement.In addition, can also be chosen in that the compile script statement carries out functional development in the environment of " Visual C++6.0 ".

The present invention has at first carried out comprehensive thinking to Spatio-Temporal Data Model for Spatial, has proposed the Spatio-Temporal Data Model for Spatial of Geographic Information System, and contents such as its model restriction, application scenarios, data structure, version, version management are designed comprehensively.The present invention simultaneously, simulates real positive activity situation, design application scenarios, preparing experiment data, and utilize script sentence and SQL statement, in the environment of land use planning system, intuitively showed time management to the land use planning system data.
