Shift between my published services and ArcGIS Online Base Maps

HaniDraidi — Wed, 11 Feb 2015 22:41:18 GMT

I have a map that contains a layer in “Palestine 1923 Grid WKID= 28191”, when publishing this map via ArcGIS online and adding it to an ArcGIS online map, the layer of the map service is shifted from the ArcGIS online base map.

The same thing happens with services published by ArcGIS Server!

This is better illustrated with the screenshots below

How can I publish my services and add them to ArcGIS online maps with no shifts between them and ArcGIS online base maps?

Note: The coordinates of the features in the layer are accurate and have been verified by an accurate GPS

Any help is appreciated,

Hani

1- The map in ArcMap

2- The map is published as ArcGIS online service

3- This ArcGIS Online service is added to the ArcGIS online map, and there is a shift between it and the imagery base map.

There might be something weird going on when ArcGIS Online re-projects your data to fit to its coordinate system.

Have you tried doing that yourself before you publish it? ArcGIS Online uses WGS 1984 Web Mercator (auxiliary sphere).

Hope this helps!

I have a similar problem with portal. Did you find a solution?

Many Thanks for the prompt contribution Tim,

Do you mean that I should project all my layers into AGOL Coordinate system (WGS 1984 Web Mercator (auxiliary sphere)), before plugging them into AGOL maps or apps?

Thank you again,

Hani

DeShawn,

Up to now, I did not resolve this problem, I'll keep you posted with any updates

Thank you

Try changing your dataframe in Desktop to WGS 1984 Web Mercator (auxiliary sphere) and export your feature class to a shapefile or FileGDB, be sure to click "The data frame" when the export window opens. Then open a new .mxd and bring the exported file in so both the feature and the dataframe are set WGS 1984 Web Mercator (aux sphere) and publish the service from there.

Hi Hani,

The basemap in ArcGIS Online sets the projection for the webmap. If you are using an out of the box basemap provided by Esri, then the projection of your web map will be Web Mercator Auxiliary Sphere. If your data needs to be transformed in order to display correctly in the Web Mercator Auxiliary Sphere then please perform the correct projections and transformations prior to publishing.

You can also create a tiled basemap in the projection that your data is in and set it as a basemap. This will ensure that all data in the web map is the same projection as your basemap and your data will line up.

Here is some documentation regarding Basemaps in ArcGIS Online:

Many Thanks for the suggestions Kelly,

I used my own basemap, and this solved the problem!

Thank you for your valuable response Tim,

Actually, I have multiple map services which contain layers in "Palestine 1923 Grid" PCS, and it will take me a long time to re-project them to WGS 1984 Web Mercator (auxiliary sphere) GCS.

I think that Kelly's solution (using my own basemap) can resolve the problem with minimum changes.

I tried your suggestion for a single map service, but still, there is a shift between Esri standard basemaps and my services, I think that this happened because I did not use the right transformation (which I do not know). By the way, do you have an idea of how I can find the right transformation between two coordinate systems. For example between the "Palestine 1923 Grid" and the WGS 1984 Web Mercator (auxiliary sphere)?

Once again, thank you very much for the contribution

Unfortunately, I don't know which transformation to use during the re-projection, there are no suggested transformations listed in ArcMap when doing the export. I see that the Palestine 1923 Grid is based on a Cassini projection and a Clarke_1880_Benoit spheroid, which will come into play with the transformation, but you may need to work with someone at Esri to get some guidance on this.

Hani,

Have you found the right transformation for your data (with GCS_Palestine_1923 WKID: 4281 Authority: EPSG) to be converted into WGS 1984 Web Mercator auxiliary sphere (WGS_1984_Web_Mercator_Auxiliary_Sphere WKID: 3857 Authority: EPSG)?

If not yet, please try 'Palestine_1923_To_WGS_1984_1' in ArcGIS

Many Thanks Larry

You are right! I tried this transformation and it worked fine!

Hi Kelly,

Does this mean that if our data is in a datum like NAD 1983 HARN, we need to select a transformation in the ArcMap Document before publishing or that ArcMap will automatically select one when we bring the data in? This page https://enterprise.arcgis.com/en/server/latest/publish-services/linux/author-feature-services.htm

claims a transformation will automatically be performed if one is not selected, but when I look at the 'Transformations' box in the data frame properties, it reads 'None'. I want to be sure I am testing my GNSS units against control points properly.

Thanks,

Mitch
