According to the solutions of transformation parameters and corresponding residuals between DHDN and ETRF, detail analyses for global and regional transformation are performed, which show that the global accuracy of the transformation between DHDN and ETRF is \u00b15 m with WRMS (weighted root mean square) of\u00b10.64mand regional transformations have much better fitting. Through the comparisons of estimated parameters of each state, the systematic differences in definition and observation among regional systems of DHDN have been confirmed. Practical usage of 7 parameter similarity transformation and some suggestions are pointed out.<\/p>\n<p><a href=\"https:\/\/www.jstage.jst.go.jp\/article\/eps1998\/52\/11\/52_11_947\/_pdf\/-char\/ja\"><\/a><\/p>\n\n<div class=\"wp-block-button\">\n<a  data-e-Disable-Page-Transition=\"true\" class=\"dlm-download-link dlm-download-button wp-block-button__link wp-element-button\" title=\"\" href=\"https:\/\/jsapt.net\/ja\/download\/17381\/?tmstv=1791167457\" rel=\"nofollow\" id=\"download-link-17381\" data-redirect=\"false\" >\n\t&ldquo;The systematic analysis of the transformation between the German geodetic reference system (DHDN, DHHN) and the ETRF system (DREF91)&rdquo; \u3092\u30c0\u30a6\u30f3\u30ed\u30fc\u30c9\t<span class=\"dlm-button-meta\">ja\t\t&ndash; 855 \u56de\u306e\u30c0\u30a6\u30f3\u30ed\u30fc\u30c9\t\t&ndash; 1.21 MB<\/span>\n<\/a>\n<\/div>\n\n<p><!--------------\nType : URL\nURL : \u30c0\u30a6\u30f3\u30ed\u30fc\u30c9\u6b04\u53c2\u7167\nCategory 1 : \u30ab\u30c6\u30b4\u30ea\u30fc\u6b04\u53c2\u7167\nCategory 2 : \nTag : \u30bf\u30b0\u6b04\u53c2\u7167\nOption : \n--------------><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Jianqing Cai [ Link to j-stage ] Abstract -
