Using ArcGIS Desktop 10.x and ArcGIS Pro 2.1 I want to do what&nbsp;I think should be straightforward enough and carry out an analysis, like calculate Euclidian Distance, on port locations across the globe.</P><P></P><P>With this analysis, I want to see the calculation results continue across the max/min line of longitude (e.g. 180 and -180 degrees) so that the whole sphere is covered. For example, the results should show spatial relationships between Auckland and Los Angeles.</P><P></P><P>I assume this analysis not running spherically is because a raster analysis works in a 2D space where the left-hand side does not relate to the right-hand side.</P><P></P><P>Is there the possibility within ESRI software to run a raster analysis where the "left" and "right" are "aware" of each other?</P></BODY></HTML> Fri, 03 Aug 2018 11:42:00 GMT https://community.esri.com/t5/coordinate-reference-systems-questions/how-to-run-raster-analysis-globally/m-p/758532#M99 SimonKettle 2018-08-03T11:42:00Z Re: How to run raster analysis globally? https://community.esri.com/t5/coordinate-reference-systems-questions/how-to-run-raster-analysis-globally/m-p/758533#M100 <HTML><HEAD></HEAD><BODY><P>I am not sure even a 0-360 spatial reference would help for all locations, but you could try shifting the raster 180 degrees or something first</P><P><A class="link-titled" href="http://pro.arcgis.com/en/pro-app/tool-reference/data-management/shift.htm" title="http://pro.arcgis.com/en/pro-app/tool-reference/data-management/shift.htm">Shift—Data Management toolbox | ArcGIS Desktop</A>&nbsp;</P></BODY></HTML> Fri, 03 Aug 2018 12:11:41 GMT https://community.esri.com/t5/coordinate-reference-systems-questions/how-to-run-raster-analysis-globally/m-p/758533#M100 DanPatterson_Retired 2018-08-03T12:11:41Z Re: How to run raster analysis globally? https://community.esri.com/t5/coordinate-reference-systems-questions/how-to-run-raster-analysis-globally/m-p/758534#M101 <HTML><HEAD></HEAD><BODY><P>I did change the tool environmental settings to run the analysis 0 - 360 longitude but I just moved the edges to Greenwich Meridian rather than 180 in the Pacific Ocean...</P><P></P><P>The only real workaround I see is to run the analysis twice and present static images not a global map or globe with the results. But with the ability to show data on ArcGIS Earth etc I would prefer to show the raster calculations globally without the edges being present.</P></BODY></HTML> Fri, 03 Aug 2018 12:24:08 GMT https://community.esri.com/t5/coordinate-reference-systems-questions/how-to-run-raster-analysis-globally/m-p/758534#M101 SimonKettle 2018-08-03T12:24:08Z Re: How to run raster analysis globally? https://community.esri.com/t5/coordinate-reference-systems-questions/how-to-run-raster-analysis-globally/m-p/758535#M102 <HTML><HEAD></HEAD><BODY><P>Simon … That seems about the only solution in the interim... think of the cup half full... thankfully you didn't have similar issues with latitude <IMG src="https://community.esri.com/legacyfs/online/emoticons/wink.png" /></P></BODY></HTML> Fri, 03 Aug 2018 12:31:10 GMT https://community.esri.com/t5/coordinate-reference-systems-questions/how-to-run-raster-analysis-globally/m-p/758535#M102 DanPatterson_Retired 2018-08-03T12:31:10Z
