Abstract

Data format of CAD often don’t accord with requirements of GIS. The paper analyzes the existent problem during data format transformation from CAD to GIS. And logic organization , layer and attribution design are studied when basal relief map and layout data with CAD data format are transformed into GIS by Geodatabase data model of ARCGIS .There , however, is still a urgent need for “National spatial data format standard ” to frame in order to solve related problem ultimatly.
