The present invention provides an
electronic information system and a method thereof, and constructs two sets of subsystems of
field data collecting and indoor
data processing. The
field data collecting
system is based on a Mobile GIS platform and is combined with
GPS positioning, GPRS network,
bluetooth communication, etc. The
field data collecting
system realizes high-precision positioning of earth monitoring, uses different methods for executing difference positioning, digital information collecting, eraser
list constructing, photograph taking / camera shooting evidence obtaining and
terrain hyperlinking for realizing
electronic information of field land surveying at the state with / without VRS network. The indoor
data processing system is based on SuperMap GIS developing platform and Browser /
Server structure, and is combined with
XML data interchange, spatial geographical
coordinate projection switching, overlapping analyzing, etc. The indoor
data processing system realizes multiple functions of indoor multi-source map data expression and operation, combined inquiry,
report generation, land monitoring
database updating, property formwork customizing, etc., and realizes
electronic information of indoor land monitoring operation.
