Chapter 6 Installation of GIS


6-1 Plan for GIS Installation

Installion planning is divided into three phases; planning, anlysis and implementation.

The First Phase : Planning
Step 1 : Proposal of Plan
The objectives, rationale, system configuration, database, budget, scheduling etc. should be proposed.

Step 2 : Review of Plan
The proposed plan should be circulated and explained at the related departments or divisions to obtain the consensus in the bottomup approach.

Step 3 : Approval of Plan
The plan should be approved by the top-manager particularly with respect to the policy and strategy of GIS installation.

Step 4 : Organization of Project Team
A project with well defined terms of reference should be organized.

The Second Phase : Analysis
Step 5 : Pilot Scale Feasibility Study
A pilot scale feasibilitiy Study should be made by the project team in consultation with GIS experts.

Step 6 : Approval of Pilot Project
The pilot project will be approved particularly with respect to the budget.

Step 7: Drafting of Specification
Specifications for hardware and software, as well as database structure should be made.

Step 8 : Selection of Vendor
A vendor will be selected through bidding.

The Third Phase : Implementation
Step 9 : Design of Database
Data acquisitions, maintenance and updating with well defined data format and database model should be designed.

Step 10 : Implementation of Pilot Project
A small scale GIS project should be tested as a pilot project in coorperation with the selected vendor

Step 11 : Review of Pilot Project
Database design, data input cost, performances of hardware and software and so on should be reviewed and improved.

Step 12 : Purchase Order of Systems
Hardware and software should be purchased.

The following steps are common flow of the last stage.

Step 13 : Training
Step 14 : Data Input
Step 15 : Daily Operation
