Downloads not in correct projection system

MattCashen — Tue, 18 Dec 2018 16:01:59 GMT

I'm trying to set up an ArcGIS Hub site and I have the ability to download data in local projections enabled. The projection system used for my data is NAD_1983_StatePlane_Indiana_West_FIPS_1302_Feet
WKID: 2966 Authority: EPSG

However, whenever I download anything off the open data site the download is in this projection system:

NAD83_Indiana_West_ftUS_deprecated
Authority: Custom

This is a major problem as this custom projection system is around 2,000 feet off from the correct projection system. Is this a known problem or is there something I need to be doing to make sure my downloads are in the right projection? I have tried uploading layers to AGO using both ArcMap and ArcGIS Pro and both methods give me the same wrong download projection.

Hi Matt, would you mind sharing a URL to your dataset?

https://data1-lakeingispro.opendata.arcgis.com/datasets/centerlines

I just posted this dataset this morning as I'm still trying to trouble shoot this. This was a feature class that I exported to a shapefile before uploading to AGO using ArcMap. I've also uploaded feature classes without exporting them to shapefiles first. Both methods have produced the same end result.

Sorry, I accidentally deleted the layer I sent you the first URL to. Here is a link to an active layer that is still downloading in the wrong projection.

Hi Matt, the Service URL associated with https://data1-lakeingispro.opendata.arcgis.com/datasets/lakecounty-centerlinestakes me to https://services5.arcgis.com/8CXRnvSfSpwdf0R6/ArcGIS/rest/services/LakeCounty_Centerlines/FeatureServer/0. I can see there that the ArcGIS hosted service layer has WKID 2245, rather than 2966 as you note in your initial comment. WKID 2245 is "NAD83_Indiana_West_ftUS_deprecated". So the problem here isn't with Hub, as it is downloading the data according the projection system defined for the layer on the service.

Can you check the source data for that ArcGIS service and confirm its spatial reference? Perhaps it was uploaded as 2245 mistakenly?

I see what you are saying. When I look at the URL for the service it does say 2245 is the spatial reference. However, the source layer I'm publishing from ArcMap is showing 2966. As seen in the screenshot below. Is it possible that there is some error happening in the publishing process to cause this? And if so, is there a way to fix that? I'm using ArcMap 10.6 to do this publishing.

Hi Matt -

I'm probably not the best resource for your issue now that we have determined that the problem occurs in the transfer from ArcMap -> ArcGIS Online (I am a Hub developer) . You may want to repost under a more appropriate GeoNet topic.

Indeed, it looks like your ArcMap data is in 2966. What is the spatial reference of the map that it is a layer in (in ArcMap)? Perhaps the map is in 2245, while the layer is in 2966; perhaps the publishing process use the map spatial reference rather than individual layers spatial reference.

The data frame properties of the map also show the correct projection system. Thanks for helping me narrow down where the problem appears to be occurring. I'll post in a more appropriate topic to hopefully get it solved

Hi Rich,

I was wondering if you would have some insight into something else I noticed. When I publish a layer on ArcGIS Pro and check the box that allows others to export to different formats, it makes a file geodatabase download option available on the ArcGIS Hub layer page. If I download the file geodatabase, it downloads the layer in the correct projection system. If I download the shapefile, it is still the incorrect projection system. Do you know of why that might be happening? Or is there a way for me to turn off the shapefile download option?

Hi Matt,

Does any data in WKID 2966 display the same behavior? Or just this one service? Has this happened with any other projections that you've seen? Hopefully that will narrow down the issue; and it's possible that this is a bug. Are you able to contact Esri Support Services to see? I'm hoping so!

Can you post the link to the Hub page that has a geodatabase download? I don't see such an option here: https://data1-lakeingispro.opendata.arcgis.com/datasets/lakecounty-centerlines

Hi Matt -

I would keep trying to determine why the publish process creates services with 2245 when your data begins in 2966. Hub will generally obey the SRID of the service.

You're right that the FGDB download at https://data1-lakeingispro.opendata.arcgis.com/datasets/lakein-lgim-sdedata-corp-polydoes comes back as 2966, which is different than that stated by the serrvice. But your hub site is V2 and it runs some older code to generate this FGDB. It's scheduled for automatic upgrade.

This is only speculation, but perhaps hosted services doesn't yet support 2966 and it's instead grabbing 2245 because it is the closest match (again, that is a total guess). I would reach out to Esri Support Services.

Hi Matt,

Just discovered exact same issue here in Southern Indiana. I tested on the newer version of the Hub Open Data Portal, and received the same NAD83_Indiana_West_ftUS_deprecated system for the shapefile download. Did you ever determine a resolution?

Re: Downloads not in correct projection system

LauraGillespie — Wed, 05 Jun 2019 17:11:10 GMT

ESRI has determined this is a BUG, #BUG-000122648 ArcGIS Online converts feature services published in NAD_1983_StatePlane_Indiana_West_FIPS_1302_Feet (WKID 2966) to NAD83_Indiana_West_ftUS_deprecated (WKID 2245).

Are any other Indiana Counties having this same issue?
