今天就跟大家聊聊有关Python中怎么实现数据转换,可能很多人都不太了解,为了让大家更加了解,小编给大家总结了以下内容,希望大家根据这篇文章可以有所收获。
import pyfme FME_GEOMETRY_TYPE={ 0:"FME_GEOM_UNDEFINED", 1:"FME_GEOM_POINT", 2:"FME_GEOM_LINE", 4:"FME_GEOM_POLYGON", 8:"FME_GEOM_DONUT", 256:"FME_GEOM_PIP", 512:"FME_GEOM_AGGREGATE", } session=pyfme.FMESession() dialog=session.createDialog() pr=dialog.sourcePrompt("","") reader=pyfme.FMEReader(pr[0]) reader.open(pr[1],pr[2]) pw=dialog.destPrompt("","") writer=pyfme.FMEWriter(pw[0]) writer.open(pw[1],pw[2]) theend=True while theend: feature=pyfme.FMEFeature() theend=reader.readSchema(feature) if theend: print "\n------------%s----------" % "Schema Feature Infomation" print "Geometry Type: " + str(FME_GEOMETRY_TYPE[feature.getGeometryType()]) print "Feature Type: " + str(feature.getFeatureType()) print "CoordinateSystem Name: " + feature.getCoordinateSystem() csm=pyfme.FMECoordSysManager() csp=csm.getOGCCoordSys(feature.getCoordinateSystem()) print "CoordinateSystem Information:\n%s\n" % csp writer.addSchema(feature) theend=True while theend: feature=pyfme.FMEFeature() theend=reader.read(feature) if theend: print "\n------------%s----------\n" % "Data Feature Infomation" print "GeometryType: " + str(FME_GEOMETRY_TYPE[feature.getGeometryType()]) print "FeatureType: " + str(feature.getFeatureType()) print "CoordinateSystem: " + feature.getCoordinateSystem() print "CoordinateSystem List:\n%s\n" % feature.getCoordinates() writer.write(feature) reader.close() writer.close() del reader del writer
