A R&D Program for Prompt Response about Forest-Protection Information with Platform Display System
The System Functions
This research performs the whole system to an executive file, which is operated independently. This system can be carried to install in any computer or Notebook computer. The following functions are included:
The Functions of Digital Map
Digital maps operate the system mainly. The digital map has the followed functions:
The Overlay of Map Layers
At anytime, the system combine forest topographies and forest cadastral maps as basic map, and then join in the administrative district map (Fig 8), hydrographic map, gradient map, imaging map, forest patrol-trail map (show as Fig 9) and forest calamity place coordinates etc, to construct an integrated GIS on the map layers for rescuing.
Basic Operation
The Basic functions of digital map are enlargement, reduction, displacement and revolution.
Information Inquiring
While clicking mouse on digital map screen, the system will display the clicked point interrelated information immediately, or one can key-in some data in inquiry item to filtrate the place and information which is required.
Fig.8 Administrative district map
Fig. 9 Forest patrol-trail map
Map Printing
Printing the map in needed scale from plotter for analyze and consulting.
The Sub-system Function for Forest Patrol
The Essential Maintenance Data of Forest Patrolmen
Includes the ID, name, department of forest patrolmen, which would be identify and match the transmitted coordinates.
The Data Receiving of Portable GPS Receiver
The system provide two ways to get GPS data, one can immediately transmit the coordinates information which obtain from GPS receiver to forest workstation computer by radio modem, or download GPS data to computer from GPS receiver directly, when coming back to the office.
The Sub-system Function of Forest Disaster Prompting Propagation
-
The Forest Disaster Prompting Propagation Data Maintaining
This operation includes forest disaster information, calamity region coordinates, instant scene pictures etc. The collecting information will be distinguished in primary file and detailed files. The primary file record essential information of calamity region, the detailed files record post-conduction after forest calamity.
- The Forest Disaster Prompting Propagation Data Transmitting
This system compress recorded files to transmit the data by Internet or compact disks.
- The Identification Number Maintenance of Forest Disaster
This operation includes each type of forest disaster identification number.

DGPS Base Station Establishment
This research project intent to promote the positioning accuracy, to establish a DGPS base station in Tahu Forest Work Station, receiving GPS message for whole time in everyday, and link with main system, so get the better differential correction value in computer. While hand-held GPS receiver's data of the patrolman has been linking to computer, the patrolling trail correction data has been done automatically.
Before establishing GPS base station, the base station setup the Leica system 300 GPS receiver, in the mean while also setup same model instrument in 5 known coordinate control point located around the base station within 3 kilometers, while performing static GPS surveying more than one hour, then post-process the GPS observations with Leica Ski software to get the local coordinate of Tahu base station.
Web inquiring forest calamity
Through the network to display the forest calamity, then establishing the common sense of protect forest.
