Geo-informatics is a useful tool for the environmental applications that comprises of Remote Sensing (RS), Global Positioning Systems (GPS) and Geographic Information Systems (GIS). In recent times large amount of geospatial datasets have been efficiently manipulated and analyzed with the help of these technologies which allow the combination of real-time data with the information of their precise positions. Data from GPS survey, Satellite Imageries of different resolutions, photographs and secondary sources. These data area analyzed by different GIS and Statistical Techniques. Results include the frequency, density, diversity and spatial distribution of flora within study area. Simpson's Diversity Index for the Site 1 is 0.096774 and for the Site 2 is 0.068263. Similarity Index for both sites is, 30%. With the help of the resulting maps and inventory most precious plants will be preserved and could be helpful for many researchers and planners.
