摘要：This. paper. focuses. on. the. validation. as pect. of. the. geometric. calibration. approach. as. implemented. for. the. Multi- angle. Imaging. SpectroRadiometer. (MISR),. a. part. of. the. payload. for. NASA's. Terra. spacecraft.. The. MISR. instrument,. launched. in. December. 1999,.continuously.acquires . a. systematic ,.global,.multi- angle.imagery.in.reflected.sunlight.in.order.to.support.and.improve.studies . of. Earth's. ecology. and. climate.. Moderate- resolution.data. acquired. with.a. unique. configuration. of.nine.fixed. pushbroom.cameras . need. to. be. autonomously. georectified. prior.to.use.in. subsequent. scientific.retrievals..A.robust.data. production. algorithm.is. bas ed. on. in- flight. generated. calibration. datasets. produced. at. the. beginning. of. the. mission. and. operationally.validated. in.the. first. two. years..However,. in.order.to.maintain.required.subpixel.co - registration.accuracies,.globally.and. throughout.the.life.of.the.mission,. data. production. operations. are. complemented. with. a. quality. monitoring. system.. This. system. has . been. critical. in:. 1). resolving. impact.issues.that.georectification.quality.may.have.on.subsequent.retrievals,.2).providing.bases.for.decisions.regarding.updates.of. the.calibration.datasets.and.production.algorithm,.and.3).evaluating.and.summarizing.overall.pointing.stability.and.georectification. performance.. With. the. series. of. quality. investigations. focusing. on. the. georectification. requirements,. it. was. determined. that. the. pointing. stability. of.one. of.the. cameras. is. not.as .good. as. the. other.eight. cameras.. As. a. res ult,.the. data. production.algorithm. has . been. updated.to.assure. uniform.georectification.and. co - registration. performance.prior.to.processing.a. final.data.collection.for.the. entire. life.of. the. mission.. Presented. in.this. paper. will.be:.an. overview.of. the.calibration.approach.and.related.quality.monitoring. system,.operational.results.prior.to.and.after.the.final.implementation.and.the.global.summaries.on.geospatial.data.accuracies
