Study of setting up County Forest Resource Management Information system based on Web and GIS
(4) Statistic and Analyzing Data
This module provides all kinds of statistical results of forest resource things of sub-compartment, compartment, forestry farm and forestry bureau for forestry units; for example, information system can compute the forest resource data of sub-compartment, compartment and forestry farm for forestry farm, and can compute the forest resource data of sub-compartment, compartment, forestry farm and all county forest resource data for county forestry bureau., moreover, the computing types of data can be customized by users’ needs, the computing results can be output in report forms or thematic map.
(5) Making Thematic Map
The system can make thematic map based on the attribute data of sub-compartments, compartments and stock map or result of statistics, the types of the thematic map is individual values maps, ranged maps, dot density maps, bar chart maps, pie chart maps, and so on.
(6) Outputting Report Forms and Management Users
- Outputting Report Forms: output results in report forms
- Managing Users
In order to assure integration and safety of system and data, considering works of forestry workers, the system has four groups to manage the forestry works, every group has some rights to deal with forestry works that the users can do and have to do on their own responsibility. The users of first group are administrator, who mainly initialize the system and maintain database. The users of second group are leaders of forestry units, they can add, delete and edit users because they have the right to arrange the forestry workers what to do. Different users have different right to deal with different forestry works, the leader of the units can query, compute forestry information and print the report forms, and moreover they can attain data from the technology satrap. The users of third group are technology satraps, who are the forestry experts, they verify and check the data in order to assure their correctness and availability, after that, they will report the data to superior units like county forestry bureau; with the need of forest management, they can query and compute all the forestry data in order to make the management project. The third group users play an important role in forestry units, they are all forestry expert. The users of fourth group are data inputting workers, they input data into database.
6. Discussion and Conlusion
In this research, the forestry thematic GIS have been developed with the OO programming technology and component GIS, it overcomes the disadvantages of high cost and difficult operation of professional GIS; integrated secondary development can take advantage of the function of management spatial data and strong function of space analysis of GIS but also take advantage of the high efficient & convenient of the OOL, so it can highly improve the efficient; a WebGIS system based on MapXtreme with Asp and VBScript in the system is a good test to accelerate GIS technology popularization in society.
Based on web technology and integrating the models of B/S & C/S, the research realizes the need function of forestry units and the public with the models of B/S and C/S, meets the need of all users of forestry units and the public; at the same time, the paper study the model of forestry data flow transferring, computing and reporting based on studying the subject relation of forestry units, which change the tradition forestry information flow model and improve the efficiency.
Setting up forest resource management information system based on GIS and web is the trend of forest resource management in new age. With the experience of developing and actualizing this kind of system, some following suggestions are proposed:
(1) Strengthen research on all kinds of model
When this kind of management information system is set up, forest resource information can be shared, so what firstly should be done is to study model in order to resolve professional problems, only in this way, forest resource management information system based on web and GIS can exert all function.
(2) Unify data standard and information encoding
How to unity the data standard and gain the basic forest data is a big problem and the first thing to resolve is to set up this system. Only in this way the forestry data can exchange and share efficiently.
(3) Change ideas
Forestry construction, ecological environmental and construction are things closely linked with every citizen, every citizen should care for forest resource managing, issue one's own opinion, and give advice for the forest resource management, which will make the forest resource management information system based on WEBGIS to play its full function.
