Capillary electrophoresis digitized fingerprints of Sophora flavescens Ait.;

HPLC digitized fingerprints of Radix et rhizoma seu caulis Acanthopanacis senticosi;

The digitized fingerprints of the pedicel of Cucumis melo L.by capillary electrophoresis;

HPLC digitized fingerprints of Fructus Gardeniae and its normalization;

A method of selecting coordinate transformation model in map digitization;

A variance analysis method is used to estimate the synthesis variance of coordinate data in map digitization.

Maps as being the most fundamental and essential data sources of database as well as GIS and RS, data precision of map digitization has become a matter of common interest to all related disciplines.

Combined with the digital map system of Heilongjiang provincial mobile communication,this paper discussed the function of digital map product in the GSM network programming and optimizing and the application of GIS in the mobile communication area.

Mapping with GIS, RS and GPS that relates to data collecting, inputting, compiling, and it can form digital maps with varied information and relative database.

A digital map should be corrected for elimilating the systematic error of spatial data in GIS caused by the deformation of the map and scanning digitizing.
