Data Publishing
The system has various data layers and Oracle/SQL tables. In order for end users to access the data database internally and externally, two different types of data publishing are anticipated. One is to deploy Vector data layers and Oracle tables and dbf files. A Customized Net based user interface shall be developed to provide an internal streamlined interface for accessing the land records database with full security. A Internet based GIS server shall be used for this specific purpose. For the general public, Zamabandi data (land ownership) and basic statistic information including vector images will be published onto the Web. An query interface will be written to generate spatial web pages for different data types. A full security system will be developed. If user demands for the downloading the spatial data, he may charged electronically.
Systems Functions
JAIPUR-GIS would provide the separate module for the GIS user group and Net-user group. It would consist a user-friendly front-end for natural resource managers and public users to perform routine GIS functions on geographic data that are distributed across the Internet. The JAIPUR-GIS server will create a unique directory for each remote client according to its machine IP address. Requests from a remote client might generate maps, documents, and new coverages that will be stored in the unique directory.
GIS Server - Functional Specifications:
The system will aid the planner by mapping the desired information in the following different forms:
Views
In this the desired information will be represented on geographical maps, which will be of great help in viewing distribution of desired item.
Tables
In this the desired information will be represented in the form of figures which will help in making comparison of tabular data of different years.
Graphs
In this the desired information will be represented on the graphs of either area, bar, column, line, or pie etc.
Inquiries:
Inquiries can be made by selecting the Inquire button from the toolbar on Software desktop.Response to inquiries will depend on the current active theme.
Queries:
Queries can be made by selecting the Query button from the toolbar on software desktop. Response to queries will depend on the current active theme.
Tables
System should also provide the facility of browsing the attribute values in any flexible manner.
- When the user selects the Tables option form the Software pull-down on the menu bar, a dialog box [Table Picker] pops up asking the user to select the Year, of which to use the tables, and tables. Here, the Year is a multi-selection list box, meaning that it will allow the user to choose more than one year of information which will be very useful while comparing the figures of different years.
- Another dialog box, [Field Picker] pops up asking the user to select the fields out of the tables selected.
- After pressing OK button, the results are shown in the tabular form with the facility of getting hard copy.
Graphs
Software should also provide the facility of building graphs out of the selected tables and fields. It should provide the facility of plotting these different graphs:
- Area chart,
- Bar chart,
- Column chart,
- Line chart,
- Pie Chart
- When the user selects the Graph option form the Software pull-down on the menu bar, a dialog box [Table Picker] pops up asking the user to select the Year, of which to use the tables, and tables. Refer section "Tables" above for the view of dialog box.
- After the user selectes OK button, another dialog box [Graph Builder] pops up asking the user to input requisite values.
After pressing OK button, the result is shown in the selected graph type.
Net/Web Server - Functional Specifications
Map: Allows user to create and display maps based on the user's selected distributed geographic data.
New Map: Enables users to create a new map from the available coverages or coverages generated from a spatial analysis function.
Add Themes
Allows users to add more themes (coverages and georeferenced images) to an existing map.
Update List
Updates the list of available themes for the user to display and analyze.
Distance
This tool measures the distance and area of user defined regions. The JAIPUR-GIS client automatically keeps track of the corresponding geographic location in response to the mouse location, while in this mode.
Query
This function displays the attributes of themes selected by the user. The result is displayed as table(s) in a HTML document on a new browser window. The spatial query is currently handled by GIS server. Spatial Analysis JAIPUR-GIS would supports the following spatial analysis functions: buffer, intersection, union and erase. The GIS server handles these functions. The resulting new coverage is stored in the unique directory created for the remote client. Currently, the user has to update the theme list in order to view the results of a spatial analysis function.
Security:
This server would fully secured for unauthorized entry. Most of data and maps would be available for the general user. Th e restricted data can only usable after entering proper User-Id and Password. The downloading of spatial as well as non-spatial data would be available after the payment of desired amount through e-transaction method.
