In the late 1990s, Critical GIS was built on the discussion which was emerged soon after the quantitative revolution in Geography and it is therefore a key stone in the history of Geographical research. Additionally, it has been known that Geography has also a long tradition of critical Geography (e.g. feminist Geography, Marxist Geography). As a result, critical GIS has become a research subject on the basis of the papers published by Schuurman and Kwan in the end of 1990s. This conference proceeding paper includes a review of literature on critical GIS in order to answer following questions:
a) What is Critical GIS? and How is it evolved in the historical perspective and what are the main research topics on which the Critical GIS focus?
b) What are the ethical issues facing GIS in the literature?
In order to address the questions above, a detailed literature review to be undertaken by focussing on the subjects in the prestigious journals of this field such as Progress in Human Geography, Geographic Information Science, Transactions in GIS and Cartography. Having the papers published in these journals being reviewed in detail, a critical perspective on the literature has been reflected.
