FeedbacksFeedbacks

The system has been implemented for 4 different districts

Mr. Le Viet Cuong: SPPD Hai Phong said:

The system is user friendly, It is not difficult for DDP staffs to use functions in web. The web gis application is very helpful for the decision-maker to know the overview of plan, good insect or pest in the field. The report is flexibility based on the administrative area. It would be great for local council leaders who have quickly visual real-time information to make decisions.

Conclusion Conclusion

It is difficult to apply the project to many districts at the same time because it is complex problem. Our purpose will design one by one; and improve slowly after testing carefully.

The 2nd phase is designed to add more types of pest (Scirpophaga incertulas) and disease (Rice blast disease and leaf whitening) for PPD in Quang Ninh province.

The remote sensing images will be used in a larger area.

Conclusion Conclusion

If other districts would like to use this system, it could save more time and money to build it up, only transferring fund would be spent.
