1.        Khái niệm

Hệ thông tin địa lý (HTTĐL)- Geographical information system ( GIS) là một tổ chức tổng thể của bốn hợp phần: phần cứng máy tính, phần mềm, dữ liệu địa lý và con người điều hành được thiết kế hoạt động một cách có hiệu quả nhằm tiếp nhận, lưu trữ, điều khiển, phân tích và hiển thị toàn bộ các dạng dữ liệu địa lý.
