To sum up the paper there is need to better enhance and update the GARS systems that are currently being used to extract and derive information. This need to embrace technological dynamism is quite evident as demonstrated by the shift of the GARS Program towards using a stereo model. This is generated from remote sensing data that comprises of the JERS-1 RADAR data and SPOT image data. Whereby this data is integrated with the data from land use, angle of the slope, geology, landslides, exposure to rainfall and drainage patterns. After which obtained data is entered in a GIS to develop geoharzard susceptibility maps.  Major useful data is obtainable at the Canadian, European, Japanese and the USA Space Agencies

This geological application of remote sensing in the global world is vital and fundamental on the three grounds. These grounds are reducing vulnerability of communities at risk to natural hazards, managing natural resources in a sustainable and environmentally sound way and contributing to understanding of global environmental changes and geodynamic. These quantifiable reasons capture the earth’s population welfare and economical dimension.

Despite this progress in the GARS as an application of global remote sensing as a tool of geological surveys, there are still various obstacles and challenges to reach greatest height. These obstacles are in terms of Geoscientific organizations have a challenge in adopting remote sensing technology in their operationalization activities due to high cost involved in terms of fast changing technology, computer and software costs also lack of adequate qualified persons.  Especially in developing nations is a major challenge.

Secondly, there is challenge in coordinating process between providers and users of remote sensing technologies that makes it extremely difficult for obtaining and usage of the data for meaningful purposes. While in the industrialized nations there is no wide and extensive use of remote sensing technologies, since their benefits are perceived to be low benefits. Hence there is underestimation leading to lagging behind in research directions.
