Question

FACILITY FOR INTEGRATING THE LOCATION WITH MAPS OF MP, MAHARASHTRA, CHTTISGARH, SHALL BE PREFFERED. COLORED SCREEN, AREA CALCULATION FACILITY WITH GOOD ACCURACY

Answer 1

I recommend looking at the Garmin GPSmap 60Cx, 76Cx, or eTrex Legend HCx.  They all have color screens, accept memory cards for saving data or maps, and can calculate areas.
