It is a legitimate question to ask! In ArcGIS Online, like in most online mapping platforms, Web Mercator is the default coordinate system. As many of you know, Web Mercator is not designed to minimize distortions for distance and area calculations. To address this concern is my motivation for writing this blog post.<\/p>\n<p>The good news is that you don\u2019t have to perform spatial analysis in the same coordinate system used by the web map. ArcGIS Online handles projection for you during analysis behind the scenes. Let us elaborate more on this.<\/p>\n<ul>\n<li>\n<h3>The Default Behavior<\/h3>\n<\/li>\n<\/ul>\n<p>In ArcGIS Online Map Viewer all layers in a web map inherit the coordinate system from the basemap. Web Mercator is the coordinate system of the default basemaps. However, this does not mean that data used for analysis must have the same projection as the basemap. Thanks to the ArcGIS \u201cProjection on the Fly\u201d algorithm, when a feature service with a different coordinate system and projection is added, it is re-projected on the fly onto the web map. It is important to point out that &#8220;Projection on the Fly&#8221; does not change the original data\u2019s projection. It merely displays the features in the web map coordinate system for visualization purposes.<\/p>\n<p>When you run the <a href=\"https:\/\/doc.arcgis.com\/en\/arcgis-online\/analyze\/perform-analysis.htm\">spatial analysis tools<\/a> in ArcGIS Online, the original coordinate system of the input feature layer is used for the calculations. Note that the input for analysis tools in ArcGIS Online can also be feature collections. Items such as CSV files and map notes can be added to a web map as feature collections. The published feature collections have the same coordinate system as the basemap. When the input features are not projected (that is, when coordinates are given in latitudes and longitudes), distances in tools such as \u201cFind Hot Spots\u201d are computed using chordal measurements. Within a small area (for example, a 700 km wide region), chordal distances provide a good proxy (within 0.05%) for relative geodesic distances between features and allows for faster computation within the tool applications.<\/p>\n<p>In ArcGIS Online the analysis output result layers are stored with the same projection as the input. Some online analysis tools such as merge, overlay, and find locations require multiple input layers. In these cases the output result layer will use the same projection as the input target layer or the first input layer. The only exception is the \u201cAggregate Points\u201d tool. Since the output layer from \u201cAggregate Points\u201d is a polygon layer, the projection for the output layer will be the same as the input polygon layer when there is one provided.<\/p>\n<ul>\n<li>\n<h3>Overriding the Default Projection<\/h3>\n<\/li>\n<\/ul>\n<p>With Map Viewer analysis tools, <span data-contrast=\"none\">you can set<\/span><span data-contrast=\"none\">\u00a0<\/span><span data-contrast=\"none\">the output coordinate system\u00a0<\/span><span data-contrast=\"none\">parameter<\/span><span data-contrast=\"none\"> in the <a href=\"https:\/\/doc.arcgis.com\/en\/arcgis-online\/analyze\/environment-settings-mv.htm\">analysis settings<\/a> for your web map or any selected tool. <\/span><span data-contrast=\"none\">\u202f<\/span><span data-contrast=\"none\">The output coordinate system sets both the coordinate system for analys<\/span><span data-contrast=\"none\">is, and the\u00a0<\/span><span data-contrast=\"none\">coordinate system<\/span><span data-contrast=\"none\">\u00a0for the output layers<\/span><span data-contrast=\"none\">.\u00a0<\/span><\/p>\n<p>Overriding the default behavior for the results layer\u2019s coordinate systems is also possible when calling the ArcGIS Online spatial analysis services via the REST API. With the REST API you can specify an <a href=\"https:\/\/developers.arcgis.com\/rest\/analysis\/api-reference\/spatial-reference.htm\">output spatial reference system<\/a>.<\/p>\n<ul>\n<li>\n<h3>Using Projected Basemaps<\/h3>\n<\/li>\n<\/ul>\n<p>There are times when you may want to use a basemap in a local projection or a coordinate system that is more tailored to your data instead of the default Web Mercator. This can be accomplished with a few extra steps in ArcGIS Pro. You can create your own basemap with whatever data and coordinate system you like and publish it to ArcGIS Online. An administrator can <a href=\"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-online\/mapping\/custom-basemap-gallery\/\">configure the custom basemap<\/a> gallery for your organization to enable everyone in the organization to use basemaps with coordinate systems other than Web Mercator (learn more about <a href=\"https:\/\/www.esri.com\/arcgis-blog\/products\/arcgis-online\/mapping\/here-are-some-equal-area-projected-maps-for-arcgis-online-and-how-to-make-them\/\">creating projected basemaps)<\/a><\/p>\n<ul>\n<li>\n<h3>The Geodesic Buffer<\/h3>\n<\/li>\n<\/ul>\n<p>Buffer is a commonly used analysis workflow in ArcGIS Online to generate an area around input features at a given distance. When performing a buffer operation with a dataset that has features covering a large region or when using a very large buffer distance, it is important to remember that projection distortion can have a serious effect on the results. The ArcGIS Online \u201cCreate Buffers\u201d tool creates <a href=\"https:\/\/www.esri.com\/news\/arcuser\/0111\/geodesic.html\">geodesic buffer<\/a> by default. The advantage is that this will always produce results that are geographically accurate because geodesic buffers are not affected by the distortions introduced by a projected coordinate system.<\/p>\n<ul>\n<li>\n<h3>The Equal Sized Bins<\/h3>\n<\/li>\n<\/ul>\n<p>Tools like \u201cGenerate Tessellations\u201d and \u201cAggregate Points\u201d or \u201cSummarize Within\u201d with custom binning options involve an operation to create equal sized area bins in the web map. To ensure that the areas of the bins are equal in size and appropriate for the analysis extent, these analysis tools choose an appropriate equal-area projection behind the scenes. In the next step, the generated bins are projected back to the original input spatial reference. Finally, when the result layer with the equal area bins is added to the web map, it is projected on the fly to Web Mercator for display (the default) or to the projection of your custom basemap.<\/p>\n<p>A Web Mercator projection may cause the shapes of the bins to appear distorted, especially for large bins or bins near the polar regions. However, these distortions are part of the display only and do not reflect an inaccurate analysis. This is an example when the Web Mercator basemap just isn\u2019t the best for visualization. You may want to consider a basemap in an equal area projection instead.<\/p>\n<p>In summary, although the default ArcGIS Online web map uses the Web Mercator coordinate system, ArcGIS Online spatial analysis tools support measurements in local projections and geodesic distance. You can easily specify your preferred coordinate system for map viewer analysis tools. With some extra steps, you can even make your own non-Mercator web maps.<\/p>\n<p>Happy analysis!<\/p>\n"}],"authors":[{"ID":5241,"user_firstname":"Jian","user_lastname":"Lange","nickname":"Jian Lange","user_nicename":"jzlange","display_name":"Jian Lange","user_email":"jlange@esri.com","user_url":"","user_registered":"2018-03-02 00:16:53","user_description":"Jian Lange is a principal product manager with Esri\u2019s Product Management team in Redlands, California.
