Abstract
With the popularity of Web technology and handheld devices with location sensors, every citizen can generate information and data about objects, phenomena, or natural processes occurring on the land surface and voluntarily provide for the governing bodies. This method is called Volunteered Geographic Information (VGI) and is considered to be effective, practical, economical, timely and suitable for the Internet of Things era. Many countries worldwide have used VGI in surveying and obtaining geographic information for mapping. However, in Vietnam, this is a relatively new method. In this paper, we will mention the basic issues of VGI in collecting voluntary geographic information for fundamental investigation in natural resources and environment, including issues of technology platform, volunteer community, type of data information and especially the quality of VGI. Through these issues, we introduce VGI as a complementary approach to support the fundamental investigation of natural resources and the environment
