The paper outlines geographic search technology as the future of research methodology. Due to the importance of geographical environment in the routine issues, the close connection between spatial extension and most of the phenomena running over the world, the geographic query process turns to be key factor in overcoming hazard decision-making and evalu-ation. We describe a two step process where derived output from spatio-textual research could be largely disseminated by spatial replication techniques. Spatial research differs in that it requires a combination of text and geographical data. The mathematical formula to calculate distances derives from the assertion that the Earth is nearly spherical (ignoring ellipsoidal effects) so great-circle distance formulas give the distance between points on the surface of the Earth correct to within 0.5% or so. Based on the search range and limit, we introduce the Cosine algorithm who offers better speed performance and data retrieval accuracy. Retrieved data exploit spatial replication technique potentiality. When it comes to spatial data we deal extensive amount of information. Web Gis Albania is an informative platform initially structured for academicals purposes further enriched with modules which support the spatial data circulation.
