Hello Josh, thank you for your ideas! I do have Spatial Analyst and I thought of using Zonal Statistics, but I don't know how to efficiently create a bunch of zones along the line. Any thoughts on that? Regarding the distance for the spatial join, there isn't an option to do that. I *wish* there was an option, but the only options I get when I do the spatial join is intersect or nearest points. (I don't want the intersect because the hazard layer has the road represented in it and it's just 0 - I want the hazard rating around the line). Thanks again for your idea. I will research more to see if I can come up with a way to use the zonal stats.

Hello Dan - thanks for thinking through this. You are right. I don't need an average. The most frequent hazard rating would be closer to what I need. Thanks!

Follow up: here's what I ended up doing: Buffered my roads by 200 feet With that buffered layer, extracted by mask from the hazard raster Convert those to points (deleting any that were less than 1 or null) Then I split my roads into 200 foot sections (its just a manageable distance to use) Lastly, I did a spatial join, joining the point data to the lines and used the nearest option (instead of intersect) and computed the average only. This will work for now, but I don't know what 'nearest' means. Does it just use the ones it encounters first all along the line or does it use a set distance? Would be cool to be able to set a distance. If anyone else has a more elegant way of doing this, please let me know!

I have almost the same question! My idea was to create points along the line, extract the values from the raster to the point, and then spatial join the points to segmented portions (regular intervals) of the line. But I need an average of the raster value around each point (since the roads are already represented in the raster and a value under the point themselves would just return 0).

Hello, I searched for this, but I just can't find a solution. Here's the problem: I have roads as a vector line file (geodatabase). I have a hazard layer as a raster file (values are from 0 to 10). I would like to assign a hazard rating (1 to 10) to each road. However, hazard changes dramatically from one place along the line to another. So, I know I need to segment the lines. I'll probably do them in 200-foot intervals. With that in mind, I created points along the roads every 100 feet. My idea was to extract the values from the raster layer to the 100-ft interval points, then do a spatial join to the 200ft-segmented roads. However, where the roads are, in the hazard layer, there is no hazard (0) because its a road in the raster too. Is there a way to extract the average of all the cells in a 200ft centered radius around each of the points? And can I somehow ignore 0 values? I suspect I need to do this in python, but hoping there's a tool I'm not aware of. Thanks in advance...

Yes! Sorry I didn't come back to let folks know. What I ended up doing was re-doing the join and *not* creating a view out of it. I created a new feature service layer. That worked fine. However, the attachments didn't come along. That's another hurdle I have to figure out. 😕

I'm having this problem too. The bug page says that it has been fixed. But I just performed a join and the attachments didn't come through. Has anyone figured out an elegant work-around?

Hello James, Sorry I didn't respond until now. I've successfully been able to join the two databases and create an entirely new feature service, but some stuff gets left behind. Here's what I'm doing : In an online map, I add both databases (one is the request for the evaluation, the other is the matching evaluation) I click on Analysis, then Summarize Data, then Join Features. The Target Layer is the evaluation because it has the geopoint and the picture. The layer to join to the target layer is the request - has the owner's name. I then click on the 'Choose the field to match' option and pick the street address in both. This is a one to one option, so that's all good. I get it a name and uncheck 'Use current map extent' and I leave the 'Create results as hosted feature layer view' unchecked. Then I click on RUN ANALYSIS. After a little bit, my new feature layer is added to the map (yay!). I can then create a new survey using this feature layer from within Survey123 Connect (desktop) - another yay! Unfortunately, not everything comes across to the new feature service. Most importantly: the pictures from the evaluation and all the domain/list stuff for all the attributes (over 70 attributes!). Is there anyway for all that to be copied over to the new feature service (without me adding it one record or one attribute at a time)? Thanks, Esther

Here's the set up: I have a vegetation layer I'm showing on a web map. When zoomed out, I have the data categorized in broad vegetation categories (conifer forest, hardwood forest, shrubland, grassland, etc). When zoomed in, I then have the map switch over to another view of the vegetation layer (using the visibility limits for each layer view) showing more specificity (species name, actually). Here's the problem: how do I get the color scheme I have in ArcMap (took forever, there's 70 species) up onto ArcGIS Online in a format I can then apply to that "zoomed in" vegetation layer? I don't want to re-publish the layer because it is rather large. I just want to use the color scheme. Trying to pick colors for more than 70 categories in ArcGIS Online may likely kill me. And the random colors are terrible. And the species colors need to closely match the broad category colors which was relatively easy to do in ArcMap.

Hello, I'm having trouble joining surveys and making them available while still retaining all the features from the original surveys (i.e. multiple choice options). I've tried joining them and creating a feature service *view* and creating a new survey based on that view, but that doesn't allow me to share the new survey with a group in my organization. (I just want them to be able to filter the data and create reports, not add new records or edit the database, but maybe that would be good too.) Anyway, when I join without creating a feature service view (creating an entirely separate feature service layer), I lose all the back-end stuff like whether the question was a multiple choice question or drop-down. All the fields are just text. Which is fine, but when I create a report, I don't get the option to get those nifty check boxes. Plus, some of the text answers are obscure, like, 10_20_feet when it should show as 10 - 20 feet. What work flow would you all suggest to maintain the data and functionality of the original surveys?

Thank you, Zach! I'll try that. I did share the contents of the Survey's folder with my group, hoping that it would show up for this automagically, but that didn't work. However, I didn't try deleting that stakeholder file. I might try that. But, while trying to figure it out, I realized I created the join as a 'feature layer view' - which means no editing. But I don't want to edit. I like the fact that folks can't edit it. I just want them to be able to use the Data and Analysis tabs in Survey123. I'll figure it out, one way or another. Either I'll try deleting the stakeholder file in the folder or just creating a new join that isn't a 'view'. Thanks again!

Hello, In ArcGIS Online, I have joined two survey databases on a common field and saved it as a new feature service layer. (Yay! So happy that worked.) Then, in Survey123 Connect, I created a new survey form based on that new feature service layer. I was able to successfully publish it. (Another yay!) But, now I can't share it with anyone. I get this message: Any clues?

Add on question, what if the surveys are already published and currently in use? Might I still be able to somehow merge the two? They wouldn't have to use the merged database as a survey, but rather just generate reports from it. Any advice for that scenario?

Hello, I'm putting together an Experience site for a public document. The document (a community wildfire protection plan) will be presented in a series of pages. Some of the pages will be text, others will just be links to documents and/or other website pages. Some will be interactive maps (of course). We'd like for some of the pages/maps/links to be password protected until they are ready to share with the public. Does anyone know if that's possible? I've organized my pages/links into two folders: Public Content and Stakeholder Content. As far as I can tell, the folders are just extra text. I can't actually set any properties for those folders. Is that correct? Can anyone suggest another way I should be organizing the Experience?
