Abstract While beginning to establish a German Civil GPS Information and Observation Service in 1990, the actual and (near) future GPS market in Germany was analyzed. In addition, the feasibility of using GPS for water authority tasks has been studied during past years. Typical capabilities in this area are real‐time positioning for hydrographic surveying (kinematic application) and precise transfer of levels to tide gauges and verification at offshore positions. The article describes the user interests, the requirements, some of the test campaigns, and the derived concepts for future applications. 相似文献

针对信息化海洋测绘这一重要问题进行了探讨,就目前存在的一些模糊认识进行了分析澄清。对相关文献涉及的数据信息准确性、语言表述严谨性和学术观点合理性问题,进行了核实和讨论,提出了我们的观点:一是认为对一些重要数据的引用有误,容易误导读者,影响到引用数据的权威性;二是认为海洋测绘一直就归属于测绘学科,而不是游离其外,更不宜将其纳入海洋学;三是认为不能简单用海图集合这个概念来代替海洋测绘的成果或数据集合,海图集合论不是海洋测绘的核心理论;四是认为海洋测绘一直就是按照纵向分离、横向融合的理念和模式发展的,不依信息化进程而改变,改变的只是它的发展深度和广度。 相似文献

This paper reviews differences and overlaps between hydrographic surveying and marine scientific research in the exclusive economic zone (EEZ), including the concept of military surveying. It concludes that recent trends with technology, the utility of hydrographic data and State practice suggest that hydrographic surveying in the EEZ should be under the jurisdiction of the coastal State. Paradoxically arguments for military surveys in the EEZ being outside coastal State jurisdiction appear stronger than those for hydrographic surveying. The paper offers some guidelines related to the conduct of hydrographic surveying in the EEZ. 相似文献
