简介:GPS定位技术已广泛的应用到国家基础建设的各个领域,尤其对测量学的各个方面产生了极其深刻的影响,突出地显示了GPS定位技术在测量工作中的优越性。随着GPS产品的国产化,GPS接收机迅速普及。由此,GPS接收机的检定问题就突出地显现出来。河南省现有GPS接收机上千套,而目前还没有GPS接收机的检定场所。为了更好地行使测绘行业管理职能,确保计量法规的严肃性和科学性以及计量标准的有效性和可靠性,加强测绘仪器计量标准管理的力度,河南省测绘局根据GPS测量的发展需要,决定建立河南省GPS接收机检定场,由河南省测绘产品质量监督站具体实施。
简介:【 摘要 】 目前,城镇公共排水管网建设主体多元化,竣工后的排水管网,无法正常移交到专业单位进行规范化管理。为了解决城镇排水问题,实现水环境质量根本性好转,改善城市生态环境,促进城市生态文明建设,通过先进的技术方法和仪器设备,查清城镇排水管道的健康状况并进行评估,为排水管道养护维修提供重要的基础数据和参考依据。 【 Abstract 】 At present, the main body of urban public drainage network construction is diversified. After completion, the drainage network can not be transferred to professional units for standardized management. In order to solve the problem of urban drainage, realize the fundamental improvement of water environment quality, improve the urban ecological environment and promote the construction of urban ecological civilization, through advanced technology, methods and equipment, the health status of urban drainage pipelines is checked and evaluated, which provides important basic data and reference basis for maintenance of drainage pipelines.
