With development and the putting forward of digital earth at full speed of the geographical information system,the spatial data shows strong vitality day by day in many fields such as aviation,remote sensing,surveys and draws,the traffic,water and electricity etc.There are a lot of means that the space data are gathered,digital papery map is one of the means.Combined scanning and vector practices of the tap pipe network,this paper introduces the whole produce of accomplishing vector data of tap water network by scan method using ArcGIS,each working procedure of this practice method includes image process,adjusting,digitalization,checking,the join of drawing and so on. In this paper,the facture of the warehouse of map signs is emphasized.This practice shows that this scanning and vector method is convenient and practical.
