      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hello,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I'd like to officially add the transformation to ArcGIS.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Name: CEM_ED50_ITRF96&lt;/P&gt;&lt;P&gt;METHOD = Position_Vector&lt;/P&gt;&lt;P&gt;X_Axis_Translation = -84.0&lt;/P&gt;&lt;P&gt;Y_Axis_Translation = -103.0&lt;/P&gt;&lt;P&gt;Z_Axis_Translation = -127.0&lt;/P&gt;&lt;P&gt;X_Axis_Rotation = -0.1714909&lt;/P&gt;&lt;P&gt;Y_Axis_Rotation = 0.0&lt;/P&gt;&lt;P&gt;Z_Axis_Rotation = 0.3995087&lt;/P&gt;&lt;P&gt;Scale_Difference = 1.0454368&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I tried a search as you suggested but didn't find any confirmation. If I can find an official/governmental website, I can ask &lt;A href="http://www.epsg-registry.org/"&gt;EPSG&lt;/A&gt; to add the transformation to their dataset as well.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Do you know what the accuracy is? Can you provide a test point? It doesn't have to be a control point, just something that we can confirm that the method is correct.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks,&lt;/P&gt;&lt;P&gt;Melita&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;If you want to check on the status of adding the transformation to ArcGIS, I've added a bug/enhancement request for it: &lt;SPAN style="font-family: 'Times New Roman','serif'; font-size: 12pt; mso-fareast-font-family: Calibri; mso-fareast-theme-font: minor-latin; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;"&gt;BUG-000083449&lt;/SPAN&gt;. &lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Thank you very much for your reply and interest,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;These are not officially approved values which are derived from experiences.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Please contact with ESRI TURKEY, I think they may test it easily and tell you the the method is correct or wrong.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;If it is correct, you can add this transformation to ArcGIS.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;If it has some small deviations, please request them to send you the correct values.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;ED50-ITRF96 conversion is a really big problem in Turkey and must be solved as soon as possible.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Regards..&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Cem KIRLANGIÇOĞLU&lt;/P&gt;&lt;P&gt;PhD.

      <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Cem Bey Merhaba,&lt;/P&gt;&lt;P&gt;yazdığınız datum dönüşümü için teşekkürler. Dikkat edilmesi gerektiğini düşündüğüm konuyu buraya aktarmak istedim. Datum dönüşümleri bölgesel olarak kontrol edilmelidir. Farklı bölgelerde Değişkenlik gösterebilir. ortak noktalardan yararlanarak kontrol edilmesi gerekir (sadece 4 ortak nokta her daim yeterli olmayabilir). Muhakkak biliyorsunuzdur ama yazdığınız gtf dosyası içindeki parametereleri genel olarak algılanacağını düşündüm ve kontrol edilmeden kullanılabilir olduğundan, dikkat edilmesi gerektiği için yazdım.&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>

Belki cm hassasiyetinde hatalar olabilir. Ama çok aşırı doğruluğa ihtiyacı olmayan herkesin işini göreceğini düşünüyorum.&lt;/P&gt;&lt;P&gt;Saygılarımla...&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
