The using of the color graph digitizing processing technology of the precipitation autographic record paper

is to convert color scanning graph to the digitizing data of precipitation per minute.It’s important to the research of precipitation intensity and characteristics of heavy rain

especially to the 24-hours refined intensity analysis on the observation of heavy rain.The color graph digitization of precipitation autographic record paper

is the only way to change the current situation

and it makes full use of the implications of the informations

so as to reflect the value fully. The color graph digitizing technical processing of the precipitation autographic record paper

using its system software to extract dropdown curve

can finally form the standard file of precipitation intensity per minute and hour by color graph scanning of the precipitation autographic record paper.
