The Emphasis In This Research Is On Understanding Principles And Techniques For Representing, Processing And Visualizing Sp<1tial Data In GIS. The Work Aimed To Optimize The used Of ARC/INFO .Package Through Simple Macro Language (SML). Implementation Of GlSis ARC/Info package In Digital Mapping Is Investigated This Work Introduces Concepts Of spatial Analysis And Describes Some Of tic Methods, Creating buffer zones using boundary operations performing polygon overlay and manipulating Tabular data simple commands from ARCPLOT and tables of ARC/INRO package will be used to view both the intermediate and. Final results. A practical case is studied, the Potential Sites For A Hospital Are Identified, And Data Is Prepared To Produce A Final Map And Tabular Report.
