Geospatial Technology definition:

Set of tools for mapping and data analysis related to the Earth, including atmosphere, hydrosphere, biosphere and noosphere.

These tools can be grouped into four main categories:

1. GPS: global positioning systems

2. Remote Sensing: observations of the Earth from space

3. Geographic Information Systems: manipulation, analysis and visualization of geographic data

4. Internet Mapping and Analysis: interactive integration of GPS, Remote Sensing and GIS data over the Internet.

Historical Development of Geospatial Technologies in 20-21 Century:

Geospatial Technologies would not be possible without the development of computer industry since 1970s, but many principles and functions in these tools were used and developed more than 3,000 years. For example, geometric measurements and algebraic computations were known in Ancient world of Egypt and Asia. Earth measurements were conducted by Eratosthenes in 150s BCE, revolutionary geographic principles of navigation were in use in 18^th and 19^th centuries during great geographic discoveries. But only in 20 century computer technology allowed geospatial technologies to become what they are today.

Geotechnology Development Challenges:

Two major challenges of geotechnology:

1. People are knowledgeable in their discipline but lack an understanding of geotechnology;

2. People understand geotechnology but do not know how to apply it in their discipline.
