Hi John An approach I have used is to reclassify the land cover into quantitative scores of suitability, ranging from 1 to 100, and then transform to values between 0 and 1. Getting suitable quantitative values on the suitability of certain land cover classes for your bird species can be tricky. If your observations are not heavily biased to sampling locations that may skew land cover counts, one approach would be to first use the Extract Value to Points tool, using your land cover as input raster. There is an option to append all the input raster attributes to the output features, so you will get the raster value as well as land cover class name. You will need the latter. Open attribute table and summarise on the land cover filed name. The Case field with be land cover name and under Field name again select the land cover class name and count as statistic type.  This will provide you with a count of the number of times your bird species was observed in each of the land cover types. You can now convert these counts to a value out of a 100 so that you can use the Reclassify tool to reclassify your land cover raster into a new raster with scores ranging from 1-100. One cant use decimals in the reclassify tool, so once you have done this, add a column as float data type and divide by 100 to covert to values between 0 and 1. To counteract the effect of land cover class size, for example where there is twice as much cropland to forest, then it is best to also determine the size of the different land cover classes and then normalize your count data against the size of the land cover class sizes.  This will give you a rate of suitability or preference, which would be a better measure to use in your model.  ...

If I understand the problem, then you could also try simply using a negative buffer distance (i.e. -250 m) and only those parcels large enough will have buffer fragments remaining within them. ... View more

Have you tried the Merge tool? Perhaps this can do what you are looking for. ... View more

I had the same problem as I also frequently use the identify tool to extract coordinates from the map view.  I posted a similar question a few months ago (https://community.esri.com/thread/174549 ) and Joshua Bixby kindly responded with a Pro add-on that works really well. It still works in Pro 1.4.1. Joshua wrote:  Check out the Coordinate Conversion Addin (.NET).  It is put out by one of the Esri teams on GitHub.  It has a version for ArcMap and ArcGIS Pro.  It doesn't integrate into the Explore tool like you would like, but it does provide a quick way to get coordinates of screen cursors/locations and even have them in multiple formats. ...

Thanks Dan. Yes, same approach it seems. I had trouble after creating folders using File Explorer and then these not showing up after trying to refresh. Avoiding browsing via default project folder solved this.  ... View more

There is a refresh option when adding data. The tool is the circle-like icon on upper right of the Add Data window. See the below screencapture with arrow on right.  However I did notice that refresh option does not work if you choose to browse to a folder using the default project folders when browsing (I put a X here in the below image).You have experienced the same thing it seems. Best to browse using "Computer" browse option below. This does refresh the folders and updates it to show latest files and folders. No need to restart Pro this way. ... View more

Thanks Drew but in my situation this was a relatively fresh install of Esri software on a new laptop using Pro 1.4 and Desktop 10.5 only (together with ArcGIS Earth and Add Studio). No custom installations or changes made to python. Server not running on laptop. Pro was initially installed on a laptop where the graphics card had a faulty driver. Every time Pro need to work hard and access the GPU, I woudl get a Windows error message saying that Pro was being blocked from accessing my GPU. Googling this error resulted in a fresh install of the NVIDIA driver (after even cleaning it from registry) and then error message disappeared, but then I experiences the new failure to load system tools error that is now under discussion. I was therefore under the impression that Pro and ArcMap are somehow tied to the GPU installation and any substantial changes to the GPU or configurations could compromise the installation of the Esri software. ...

Hi Ed This worked! I uninstalled all Esri software, ran a registry cleaner, and then re-installed software and now ArcMap and Pro 1.4  work perfectly. Thanks so much. ... View more

Dear Ed (and Dan) Ed, I have the same problem after purchasing a new laptop and then upgrading windows 10 from home to pro version, and then experienced some GPU driver issues. This may be the cause but I cant figure out how to work around it. After uninstalling Pro 1.4 a couple of times, I then chose to install Pro 1.3 and this runs perfectly, but as soon as I update to Pro 1.4, I get the same error "Failed to load system tools. Please restart ArcGIS Pro".  Dan, I tried resetting my application profile as suggested but that did not work. But even though I had uninstalled Pro 1.4, my computer knew what colour scheme I last used and my recent projects. So uninstalling and changing profile did not remove all pro 1.4 system information. It is storing my setting somewhere else.  Any assistance will be most welcome. I am loath to run Pro 1.3 until the next release of Pro. Thanks ... View more

You should also consider Circuitscape (http://www.circuitscape.org/) for modelling multiple paths (this does work well but be careful of cell size as it takes an inordinate amount of time to run and requires LOTS of RAM). Then if you are using Pro 1.3 and above, or ArcMap 10.5 (possibly 10.4), consider using the new "Cost Connectivity" tool that can connect up multiple patches using corridors and a cost surface. Not sure of the limits. See https://pro.arcgis.com/en/pro-app/tool-reference/spatial-analyst/cost-connectivity.htm ... View more

I would start by making a copy of your input feature layer and work with the copy. The tool I propose in your first step, Integrate, changes the geometry of your input file. So be careful. So open Integrate, and set the distance at which you would like to summarise your points i.e. your input distance will be 100 m. After running this tool, all your accident incidents within 100 m of one another will have the same geometery. Next run a Spatial Join on your input layer, using the same layer for both your Target Features and Join Features inputs. The join operation should be one to one. The resulting output will contain a field called Join_Count. This field will contain the number of points (accidents) occurring at each point on the map. ... View more

For me this error is frequently resolved when if I select to save to a geodatabase, but as Dan points out, there could be many reasons. ... View more

Thanks Dan, I agree. I took a look at this site before writing through GeoNet but I did not find any similar add-ins or scripts. ... View more

Hi Dan There was a street view add-in for Pro 1.1 that I used for a while, but this add-in is no longer compatible with the newer versions of Pro. For the life of me I cannot recall where I got this add-in from!  If I now try and run the add-in, the resulting error message seems to be written in Italian (based on Google Translate). The add-in was called PAMStreetView and there are no contact details with the associated files.  The ReadMe.txt file contains the following text: Double click on PAMStreetView.esriAddInX file for install. Note: Street View requires WGS84 so add-in projects from your coordinate system current of Map to wgs84 (for now only coordinate system based on a datum wgs84) Tested with ArcGIS Pro 1.1.1 For a bug of ArcGIS Pro 1.1.1 I use a rest service for projection in wgs84. In arcgis pro 1.2 I will use arcgis pro api Version 1.0: initial version So not to worry about this any further. I am hoping that there may be other Pro users out there that are aware of this add-in, or other similar 3rd party add-ins, that may be of assistance.  ... View more
