When I have had erase or intersect tools fail with ArcMap, I usually try: Splitting those polygons with too many vertices by running the Dice tool with a vertex limit of around 20 000. Unfortunately this tool is only available with the ArcInfo license level.  Running the Repair Geometry GP tool (it is surprising how many errors creep into the geometry during a workflow) Saving to a geodatabase But I also noticed your error message referred to "Invalid Topology [M coord limit exceeded.]" You can try converting your shapefile to a new one with M Values set to Disabled under the Environment settings. It has been many years since I opened ArcMap 9.3 so what I have written above applies to ArMap 10.x but I am hoping this functionality was available In 9.3 ... View more

This is a datum issue I suspect, not a projection one. You may find that in ArcMap a transformation has been set on your data frame, but not in ArcGIS Pro. In Pro you need to right-click on the Map properties heading, then select Transformations and try and find a suitable transformation method between the datum of your basemap and that of your shapefile.  I found a great tech video from Dev Summit 2017 on introducing projections and coordinate systems here (and includes a great overview of vertical coordinate systems)  Introducing Coordinate Systems and Transformations - YouTube . Perhaps this may help. ... View more

This really depends on what shape geometry you want to create. A circle is the easiest and can easily be created using the Buffer the GP tool for a point feature and you just need to define your radius (e.g. 50 m).  ... View more

I would also like to load a raster and a mosaic dataset into a Mobile Map Package (MMPK) but it seems one is unable to do so. Only vector data or Vector Tile Packages (that also only consume vector layers) can be used to create MMPKs. It does not look like traditional tile packages are supported within MMPKs either? Is there a workaround to load rasters/mosaic datasets/image services into a MMPKs? Ideally one would want to query them but being able to load them as a tile cache or tile package would still be helpful.  Thanks. ... View more

I would recommend you take a look at this video from the 2014 or 2015 Esri UC entitled "Spatial Data Mining A Deep Dive into Cluster Analysis". It discusses Hot Spot analysis in detail.  Video can be viewed here: Spatial Data Mining A Deep Dive into Cluster Analysis  ... View more

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
