You can't reproject an Esri basemap.</P><P>But, if you are working on ArcGIS Desktop, you could transform the basemap on the fly to a desired Projection system. You could follow these steps.</P><P>1. Open a blank Map Document.</P><P>2. Add a data (with BNG projection) to the data-frame/ or change the Projection System to BNG from Data-Frame Properties.</P><P>3. Add the desired Basemap to ArcMap.</P><P></P><P>If prompted, choose an appropriate Transformation method.</P><P></P><P>In case it is a different basemap, please provide further details about it.

Hence we cannot permanently project the basemaps to another spatial reference, however, you can change the projection of the basemap by changing on-the-fly projection ArcMap data frame properties (If viewed in ArcGIS Desktop) or can be changed from code side (is it is being consumed in some application)</P><P></P><P>I hope this helps!</P><P></P><P>~Shan</P></BODY></HTML> Thu, 07 Sep 2017 12:46:55 GMT https://community.esri.com/t5/cartography-and-maps-questions/how-to-project-the-basemap-in-bng/m-p/822516#M485 shan_sarkar 2017-09-07T12:46:55Z Re: How to project the basemap in BNG? https://community.esri.com/t5/cartography-and-maps-questions/how-to-project-the-basemap-in-bng/m-p/822517#M486 <HTML><HEAD></HEAD><BODY><P>Thank you to you 2, it works almost but my points with the basemap in BNG are now located in the sea instead of being located above London.</P><P>With the WGS1984 projection system, the points are well located.
