topic How can I transform my projection system Colombia Bogota zone to WGS84? in Data Management Questions https://community.esri.com/t5/data-management-questions/how-can-i-transform-my-projection-system-colombia/m-p/530134#M30059 <HTML><HEAD></HEAD><BODY><P>I have a shapefile for whole Colombia, but that shape file projected with Colombia Bogota zone and that boundary is not matching with google eart or google or osm boundary. So, I transform into WGS84 system but it is shifted little bit from the previous boundary and still it is not matching. I did what ever i found in ESRI tutorial. Please help me out.&nbsp;&nbsp; </P></BODY></HTML> Thu, 04 Aug 2016 04:25:27 GMT AnkuMaiti 2016-08-04T04:25:27Z How can I transform my projection system Colombia Bogota zone to WGS84? https://community.esri.com/t5/data-management-questions/how-can-i-transform-my-projection-system-colombia/m-p/530134#M30059 <HTML><HEAD></HEAD><BODY><P>I have a shapefile for whole Colombia, but that shape file projected with Colombia Bogota zone and that boundary is not matching with google eart or google or osm boundary.

We have several Bogota to WGS84 transformations, but only one is for the entire country: Bogota_To_WGS_1984. The Bogota_To_WGS_1984_2 is for a few oil fields, and the others are for various districts, not the entire country. </P><P></P><P>Bogota_To_WGS_1984 is not a particularly accurate transformation, maybe 10 m.</P><P></P><P>You might also try one of the "Region VIII" transformations. Region VIII covers the eastern half of the country to see if gives a better overall fit.</P><P></P><P>Melita</P></BODY></HTML> Thu, 04 Aug 2016 21:34:10 GMT https://community.esri.com/t5/data-management-questions/how-can-i-transform-my-projection-system-colombia/m-p/530135#M30060 MelitaKennedy 2016-08-04T21:34:10Z
