Digital mini\|area is the microcosmic description and reification of the digital earth and can be simply defined as a digital and virtual small area in concept. Based on the theory and strategy of Digital Earth

the concept of Digital Mini\|area is proposed. To develop and establish a digital mini\|area with the related technologies of the digital earth and such technologies as three\|in\|one integrative network system

intelligent mini\|area

intelligent house system and digital neural system

the general structure

the physical infrastructure

the network structure

the information structure

the function structure

the model structure

the key technologies and the integrative applications of Digital Mini\|area are then discussed. At the end

some methods and guidelines on how to develop the digital mini\|area are also given out.
