Project Task and Survey Purpose
Project Task
With the approval of the People's Government of Tuquan County, the Land and Resources Bureau of Tuquan County cooperated with the Land Survey and Planning Institute of Hinggan League to jointly complete the registration of rural land rights and the establishment of a database in Shuiquan Town, Tuquan County.
Purpose of Rural Cadastral Survey
The purpose of the cadastral survey is to obtain basic information such as the location, ownership, boundaries, quantity, use, and grade of each land, and to provide evidence for land registration. Cadastral survey is a substantial investigation in land registration to determine land ownership and clarify property rights. The results of the investigation are important evidence for protecting the legitimate rights of landowners and land users and resolving land property disputes. At the same time, the cadastral survey also can grasp the land type, quantity, distribution and utilization of a region, as well as the distribution of land among various economic componentsand among various departments ofthe national economy. It provides information gufrantee fortheeytaMihhment of scienoificlaad mtmagement system, the rational use and protection of knd, the realization dftfynamic ba^fce df total cultivated land, the regulation oflyind dupply dnd dcmend,aad tim standardization of land market.

Rural Cadastral Survey
Technical route
Focusing on the overall goal of the cadastral survey, the rural homestead survey of Shuiquan Town in Tuquan County is based on the unified national land use classification
standards, survey contents, investigation technical methods and processes, combined with the actual situation of Shuiquan Town, makes full use of the existing land survey results, and converts the existing data results in coordinate system. By using the global satellite positioning, geographic information system, database and network communication technology, through the comprehensive investigation means of internal interpretation, field investigation and verification, data collection and processing, the technical process of homestead investigation is formed, which integrates information acquisition, processing, storage, transmission, analysis and application services.
Ownership survey
Homestead ownership survey refers to the investigation of land ownership source and rights of homestead owners or users, the homestead location, boundary, area and use. The boundary point and boundary line of the land ownership of the homestead are plotted on the survey base map or the land use status map, which is identified by the landowner or user as the basis for registration and certification.
The technical requirements
(1) Surveying and mapping the base map
According to the survey scope, large scale digital status map measurement (1:500) was first completed, and main topographic elements were mapped and taken as the base map of the ownership survey.
(2) Acceptance of application documents
The application for land registration and the supporting documents of power source are the basis for carrying out the ownership investigation. The proof of homestead right source refers to the proof material of obtaining the right to use homestead legally. The investigation team shall check and count the application documents.
(3) Division and coding of districts, streets and neighborhoods
The districts shall be arranged with one letter code, and the first phonetic capital letter of the first Chinese character in the current administrative region is used as the letter code, which shall be corresponding to the 6-digit character code specified in the code table of national administrative divisions when building the database. According to the jurisdiction of the current administrative street, the street code is encoded by the method provided by the administrative division code. The street code is only used as a statistical summary, not as a part of the formal cadastral number. The neighborhood is divided into natural linear objects such as roads and rivers, which are relatively stable. The 2-bit digital code is used to compile the neighborhood number from «01». The neighborhood code is used as a part of the cadastral number. In principle, the original neighborhood division and numbering are used in this update.
(4) Parcel number and obligee code
The parcel code adopts 3-bit digital code, which is arranged according to serpentine from «001» in each village.
(5) Cadastral numbers
The cadastral number consists of «district code + administrative village code + parcel code». The district code is one-letter code, the neighborhood code is two-digit code, and the parcel code is three-digit code.
(6) Classification of land use
The classification of land use adopts the land classification standard "National Land Use Classification" promulgated in 2001, which is mainly based on land use. For a land with multiple uses, one of the main uses is the category of the land. Parcel map

Entryof cadastral attributes
Using the Southern CASS7.1 software, the parcel attribute, the boundary point, and the boundary line attribute are entered into the database and the attribute information is loaded into the graphic CoSo to automatically generate the cadastral survey electronic form.
Data storage
Before doto storage, according to She requirements of the "Land Use Database Standards" and the "Second National Land Survey Database Construction Technical Specifications", comprehensive quality inspection shall be carried out on the data, and qualified data shall be put into storage. The rural land survey database of Shuiquon Town, Tuquan County was built using the "Village Cadastral Management Information System" GIS software of Nanjing Guotf Company.
Application software and database system
The « Rural Cadastral Management Information System « GIS software is developed based on ArcGIS in Nanjing Gutu Information Tngineering Co., Ltd. The system uses the
large database of Oracle ArcSDE as the data storage and management platform. ArcSDE is the spatial data engine of ArcGIS, which is the path to store and manage multi-user spatial database in relational database management system. ArcSDE uses a client/server architecture.
System architecture
The rural homestead survey of Shuiquan Town in Tuquan County adopts ArcGIS platform. The combination of its spatial database engine SDE with Oracle, SQLServer and other large databases is the first choice of large spatial database solution, which can realize the integrated management of spatial and non-spatial, vector and raster data. The database platform adopts Oracle 10g and Microsoft Access (Personal Geodatabase) database, and uses ArcSDE as a spatial data engine for spatial data invocation and management, supporting multi-user and concurrent operations.
The application system in the C/S part is developed by ArcEngine component, which includes the desktop application system and the network application system. C/S: Client and Server are usually located on two computers that are far apart. The Client program's task is to submit the user's requirements to the Server program, and then display the results returned by the Server program to the user in a specific form. The task of the Server program is to receive the service request put forward by the Client program, conduct corresponding processing and then return the result to the Client program.
