PRODIGE Project

###
PROduction D'Information GEographique

###
Production Center for Geographic Information

### Background

In June 1996, Spot Image-Toulouse, France signed a contract with the Remote Sensing Center of the General Department (GDLA) in Hanoi, Vietnam. The scope of this project, is to set up an Imagemap production centre and to train the staff of GDLA to Remote Sensing and Geographic Information new technologies. The aim is to realize a successful technology transfer allowing the GDLA to create a nationwide Geographic Information System (GIS).

SPOT IMAGE has developed in house capabilities to design and implement large projects around the world based on Remote Sensing data.

### Some figures about Vietnam

The Vietnam is a country of 72 millions inhabitants with an area of 332,000 square meters. The total coverage of the country requires 168 SPOT images and 818 map sheets at the scale of 1/50 000.

### Use of satellite imagery

Since 1980s satellite data has been used in several applications for mapping (scales 1:50,000 to 1:100,000), Land Management with land use maps, forestry (change monitoring and development plan) and for geology mapping.

### New needs

However, new needs are now coming in the field of geographic information in order to have available an overall tool to help decision makers involved in Vietnam quick development process. Such a tool should be set up in short time and is expected to provide an homogeneous and up date information over the whole national territory. Moreover this new facilities should allow the integration of existing information such as old maps or old data base.

### Components of the project

The project will include different components. The main three parts will be the supply of satellites images, the setting up of a processing centre and a comprehensive training programme.

### 1- Satellites images

170 Multispectral images will be acquired over Vietnam providing an updated and complete coverage of the country with a resolution of 20 meters. In addition some selected areas will be covered with the acquisition of Panchromatic with a resolution of 10 meters.

These satellites images will be used to produce

SPOTView imagemaps at the scale of 1/50 000.

### 2- Production Center

The production centre will include two main components, a SPOTView production line and a Geographic Information System.

The GDLA will produce more than 800 SPOTView. The SPOTView are based on digital format which is designed to allow a direct integration inside most of GIS software. The SPOTView are also produce in analog format such as film and photo prints.

The GIS will integrate information extracted from different sources: the imagemaps, the existing maps, the existing data base and the ground survey.

These information will be used to process to the map updating and later on to produce new set of topographic maps for the coverage of the whole country.

### 3- Training Programme

A specific training programme had been designed including the main technologies used inside the scope of this project. The main topics are: Remote Sensing and GIS, Project Management, SPOTView production, Map up dating using GIS, Photographic process, System management, Software and hardware maintenance.
