You will want to try the GP tool Spatial Join. It will allow you to set a suitable match option (such as Within a distance or Boundary touches). You can all choose which attributes fields you would like to include (default choice is to include all of them)

Hi Jason Thanks for your feedback. I have already tried many of your suggestions but still I receive the error. I noted from the Drone2Map help file that "The level of detail (LOD) mesh is a representation of the 3D mesh that contains multiple levels of detail, decreasing the complexity of the model as it is divided into more levels. Fewer details are available as you zoom out in the model. For large projects, it is possible that a level cannot be generated for a high number of levels as there is a maximum number of 20,000 triangles that can be generated for each level of details." Perhaps the memory error is related to the 20,000 triangles limit being exceeded (in my case) and the irregular shape of the 3D mesh (lots of vegetation in mine). I wonder what Esri consider to be a large project? It would be nice if Esri could chime in on this discussion .... Pretty please?

Hi Paul Something's amiss with your settings. I took a look at the same area and my profile graph differs in terms of reporting elevation units. Can you confirm that your elevation units are set to "meters" under the Settings menu?

Hi Andrew Without signing in, I have access to the all the basemaps and even others if I click on the + Add New button. I was only prompted to sign in when I tried to add the Sentinel 2 views image service (which is only available to those to have a Organizational account). For me the resolution is as great as it is with ArcGIS Pro or any other of the Esri products consuming the imagery service in a 3D view. I suspect there is a problem with your installation.

Hi Xuewen I have just installed ArcGIS Earth 1.8 and all the SLPKs are loading perfectly now .... and I really like some of the new functionality. Awesome! The link to the blog post appears broken Thank you.

I forgot to add that I also found that I had to delete two fields from my input points feature layer that contained slope and aspect values in degrees (eg. 44°). Including these values was causing ArcGIS Pro to crash when trying to run the tool.

I was also struggling to get my Points Solar Radiation GP tool to run. Initially same errors as reported above. What worked for me was ensuring that my point data was in the same projection as my DEM (which was not in geographic coordinates) and then changing the Environment settings to match that of my DEM (Processing Extent, snap raster and coordinate system). I also found this link useful ArcGIS Desktop Help 9.3 - Points Solar Radiation

I have created several slpk files in Drone2Map and I could view these in ArcGIS Earth 1.6, until the latest release of ArcGIS Earth that was based on the new quartz runtime engine. With version 1.7, I could view some slpks and others not. So today I tested 14 slpk files of various sizes (26 MB through to 1.1 GB). I am able to view all of these in ArcGIS Earth 1.6.1. In ArcGIS Earth 1.7, I am unable to view slpk files larger than 450 MB and I start have trouble with files from about 170 MB. Some of them it opens and others it cant (may be related to scene layer package texture quality and size or levels of detail). I realise that 1.7 has been removed for downloading for other reasons, but I just want to make a plug for ensuring that the newest version is cable of loading the larger slpk files as the version 1.6 was able to. As a side note, ArcGIS Earth easily loads the large DSM, DTM and ortthomosaics that Drone2Map creates. DSMs and DTMs with hillshading work well, and orthomosaics too, I am just unable to visualise any variation in raster values in the DTMs and DSMs. One would need to apply a stretch function to these rasters which is currently not an option. Hopefully it will be in the near future. Otherwise thanks for a great product.

Hi Dirk Support for point cloud scene layers should be in the next release, which I think I read was due at the end of August!

Sorry about my previous posting, I was still writing that message and saving seemed to post the message. The project I was working on has 300 images and when I tried to create a slpk with HIGH texture quality and 5 levels of details, I received the below error message (Not enough memory to texture the LOD: 16646 MB < 42 864 MB). I then changed the settings to a HIGH texture quality with 4 levels of detail, and I received a similar error message (Not enough memory to texture the LOD: 14952 MB < 19 568 MB). It finally ran successfully when I used the MEDIUM texture quality option and 4 levels of detail. As I have 32GB of RAM, why the error message? Or do I need to upgrade my graphics card in order to process this imagery? I would appreciate a brief explanation as to why I received this error message and what can be done to avoid it in the future?

Is there any update as to this error? I received the same error and i am not sure whether the error message is a RAM or GPU related error message? The problem seems to arise when selecting the HIGH texture quality option when creating 3D textured mesh outputs. I have a decent laptop with 32GB RAM and 4GB GeForce GTX 1050 graphics card. option to create a slpk with a high level of detail smad I left CUDA setting checked on and with 8 CPU threads.

This caught me too some time back. You need to actually use the drop-down menu on the right to select the raster you want the function to be applied to. Selecting it in the TOC is not enough. In the below image the function is applied perfectly.

Building on from what Dan suggested, what you have provided are three independent or explanatory variables (1 - high number of households receiving food stamps, 2 - low median household income, 3 - high number of children under 18). If you want to start exploring for statistical relationships then you need a feature layer with a dependent variable that varies in abundance. If you do have access to a layer with a dependent variable, then Ordinary Least Squares (OLS), Geographically Weighted Regression (GWR) or Forest-based Classification and Regression may be useful tools in exploring your data. Do take a look at Regression analysis basics—ArcGIS Pro | ArcGIS Desktop for more information.

You wrote "I want to get polygon files of slope/aspect, then overlay/tessellate them into polygons". You seem to have Spatial Analyst extension, why not just use the Zonal Statistics as Table or the Zonal Statistics tools to populate your polygon file with the raster slope values? Be cautious when working with aspect as a summarising aspect values (0-360) will not work. For example, summarising a northerly aspect (315 to 45 degrees) may give you an average of a southerly aspect.

Hi Gunter I too would find such a toolbox useful. I have a DJI Phantom 4 Pro. I have suggested that a similar function to be added to Drone2Map whereby the user needs to provide (1) a fixed altitude of Drone takeoff site, and (2) the height of the flight, and then the image properties would accordingly be corrected. Do see https://community.esri.com/ideas/15040 . However I don't know if this will ever be implemented as it is not yet in product plan. So your proposal sounds like very useful functionality to have.
