Hi David Are you using ArcGIS Pro or ArcMap? Do your point records have any abundance data associated with them. The data points need to contain numeric values that vary in abundance and across space for the ArcGIS regression methods. If you are using ArcGIS Pro, do take a look at Forest-based Classification and Regression—ArcGIS Pro | ArcGIS Desktop and How Forest-based Classification and Regression works—ArcGIS Pro | ArcGIS Desktop for an alternative regression approach. For visualizing relationships between two variables, correlation and not regression, I frequently use scatter plots Scatter plot—Charts | ArcGIS Desktop

The process I would follow would be to right-click on the layer you plan to clip, and which has the desired symbology applied, then select the Save As Layer File option. This saves the symbology. Then do your clip and then apply the symbology from the layer file you have just saved. To do so, open the Layer Properties, then Symbology tab, then click on Import.. and browse to your layer file.

Could you check and confirm the procedure for taking maps offline? You will be provided with two blue squares in two separate steps. You use the 1st one to define your work area (study area), then you use the second one to define the level of detail that you want to take offline (the map details). So in the second option you need to zoom in to the finest level (largest scale) at which you would like to take data offline. You will notice that the estimated size is provided below this second blue box and it increases significantly as you zoom in.

You could also try a Spatial Join, with the option to summarise the attributes from your solar panels (see below screenshot). You will need to right-click on your Buildings layers and then select Joins and Relates > Joins...

What license do you have? ArcGIS Desktop Advanced? Tabulate Intersection requires the advanced license and can do the same thing. But if you have a Basic license, then you may need to do this in a few steps: (1) an Intersection, then (2) use Summary Statistics to extract the statistics you require. You could optionally Calculate Geometry between steps 1 and 2 if you are not saving to a geodatabase.

The Summarize Within GP tool should do this for you. Do take a look at Summarize Within—Help | ArcGIS Desktop You should be able to use a building name or number (if you have one, or anything similar) if you want to calculate the extent of solar panels for each building as well, just make sure to use the Group Field option. You can then link the output table back to building layer if needed.

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?

Re: elevation profile units seem amiss · ‎10-14-2018

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.
