Hi, I am trying to perfom a Spatial Join using this layer. I copied and pasted URL layer onto my ArcGIS Pro. When I perform a spatial join, it yields no results. I tried downloading one state (CA, 4 GB) which took 4 hours to download. The Spatial Join worked perfectly. I was just trying to do this analysis without having to download all the state datasets (I am working at a national scale). This is the URL I used. Thanks! https://services2.arcgis.com/FiaPA4ga0iQKduv3/arcgis/rest/services/USA_Structures_View/FeatureServer

Hi Collective Energy. The dataset you are trying to do a spatial join with is very large (125.6 GB) and that may be why you are getting no results. I would recommend you search the Esri Community (https://community.esri.com/) to see if someone else had a similar issue and a resolution. Also, you may contact Esri Technical Support (https://support.esri.com/en-us/contact).

Hello. Is there a way to read this feature layer in FME or download it offline ? I've tried many different methods and keep failing to do so.

Esri_US_Federal_Data Item Owner commented 2 months ago Delete

Hi Aaron. Yes, you can download the data by using the Export Data dropdown menu on this Items Page. However, the dataset is big and it will take a long time to download. It is better to download a subset of the dataset. You can do this using ArcGIS Pro. Zoom to an area, select the features that you want and run the Copy Features tool (https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/copy-features.htm) to download them.

What is the update frequency of this dataset? Is there a particular cadence, or is it constant?

Esri_US_Federal_Data Item Owner commented 4 months ago Delete

Hi Stace. The is no particular update frequency for this layer. We plan on updating the data after FEMA updates the data sources on their website (see the Data source statement in the Items Page).

I am unable to filter this layer by County FIPS codes e.g., 06085.

Esri_US_Federal_Data Item Owner commented 4 months ago Delete

Hi Sandra. I just tried to reproduce your issue but was unable to. I filtered using the FIPS field with the value "06085" and it displayed structures in Santa Clara County, California.

Can you clarify the year of the imagery that was used to classify the structures? To JAMALEK79 comment below on Houston -- it would be helpful to know what point in time these structures reflect. Especially valuable for disaster management and understanding what homes may have been built (or destroyed) since this dataset was produced

Hello, FEMA processed ~90,000 images, approximately 1.2 PB with collection dates ranging from 2011–2021. Another reference for the USA Structures dataset would be: A baseline structure inventory with critical attribution for the US and its territories | Scientific Data (nature.com) : https://www.nature.com/articles/s41597-024-03219-x
