Application of GIS technology and remote sensing image to draw digital topographic map of Khanh Hoa province

Abstract

Nowadays, GIS technology, digital maps and digital map platforms have been applied widely in many industries and fields to contribute to the country's development. Digital map is an essential tool in not only scientific research but also territorial management, planning and designs. Thanks to digital maps, administrative officers of the government can clearly understand the terrain, environment and other characteristics of a particular region, thus making right decisions for the territorial development and management. Terrain is the most stable as well as the most important component of the natural geographical environment, where close interrelationships occur among other components such as climate, rivers, soil, organisms,... Terrain is also the place where human production and living activities take place on the Earth's surface. Therefore, the establishment of digital topographic maps is very necessary. The digital topographic map of Khanh Hoa province illustrated in this article is the product of the application of GIS technology combined with the use of Google remote sensing images
