Hi Rob It is possible to just click and drag items under the Legend list. You may need to click on the side triangle to expand the list, or the Legend may be locked (clicking on the lock symbol either opens or locks the legend items). In my example below, I could easily drag items and that changed the order in the legend display. Regards Mervyn ​ ... View more

Your categorical data is on an ordinal scale from low to high so I suspect it is OK to use in these tools. I am not aware of any specific scale requirements, it simply needs a range of high and low values. For each of your variables, do you want to identify statistically significant clusters of high values, and statistically significant clusters of low values? If so then the (Optimised) Hotspot and Cluster and Outlier Analysis tools are the ones you need. Run both as both tools tell you something different about your data (I am not aware than any one is better than the other, they just tell you something different about your data). But these tools will run on individual datasets so they would need to be run on each of your 5 variables. I am not sure of the question you are trying to solve but if you have several datasets (for each of you variables) that you want to combine in one analysis, then consider running the Group Analysis tool to create groups that share similar values. You may want to try this on your 5 raw categorical values as well as from the outputs from the (optimised)  Hotspot Analysis. So in the latter analysis, use the z-values from each of the 5 runs in the analysis field. Before you do so, you would need to create a new feature class, or add them as columns to your existing one, and import the z-values from each of your Hotspot/Cluster and Outlier Analysis runs (which ever you prefer). The z-values represent the strength of the clustering that is observed in your data, not the areas with highest and lowest values, so it will tell you something different about your dataset that is perhaps statistically more significant. Lastly, there are some great resources from the previous years UCs that you should watch if you have not already done so.

Hi David Will it be available any time soon? Like Pro 1.3? Thanks ... View more

Hi Scot Have you tried running the Repair Geometry tool? It should fix your error but not really tell the cause. Regards Mervyn ... View more

Hi Dane So you would need to create a new shapefile or geodatabase feature, and then to this add rectangles. To do so you can run the Create Features Class geoprocessing tool. If you to not direct output to a geodatabase, then the new file will be a shapefile. Cheers ... View more

Hi Dane I am on the road so difficult to reply in detail, but I had a similar problem but solution is very easy. With the create features side panel active, open the templates window and there is an option to define the editing tools for that layer. Here you simply click on the boxes that would activate drawing tools such as rectangles, circles, etc. I am not sure why they are not all activated by default. Good luck. ... View more

Did you manage to get Multidirectional hillshading to work in Pro 1.2?  I am having the same problem importing the custom python code. ... View more

Hi Jay I think the Tabulate Area tool under the Zonal Stats toolbox will do the trick. Cheers ... View more

Hi Christopher This is the link you are looking for http://video.esri.com/watch/4702/simple-ways-to-do-more-with-your-data-using-spatial-statistics. It is still active and a great tech session. Regards Mervyn ... View more

Hi Jessie I have run this tool on a lot more polygons. I suspect something else my be at play, as Dan suggests, perhaps overlapping polygons. I gather you would have linked the zonal stats table back to your polygon data. Select those with zero values and run zonal stats tool just on these to see if perhaps now the balance of the units can be populated with soil data. Cheers Mervyn ... View more

Hi Jessie I would convert my soil data to raster, and then use *Zonal statistics as table tool* to and Majority statistics type to sect the most common soil type in each polygon. Regards Mervyn ... View more

Hi Curtis The new interface is really great ... and I like the similarity to model builder as a workflow. I have made the suggested changes my elevation raster function. I have also been trying to apply symbology to my custom raster functions and it is unfortunate that it does not accept Layer files. I am struggling to have my color ramps applied to my raster function. Thanks for advice. ... View more

Hi Joshua This add-in works like charm! Thank you. Regards ... View more

Sorry, hit send to soon. For those of you interested in this discussion and using Raster Functions to extract values, I will end by adding in a screenshot of the Function Editor where I was able to use the Greater than and Con functions together that returned the actual elevation values above a certain threshold (1400 m in this example). If there a simpler way of doing so, I would love to hear from you, but it was possible :-). Thanks to Dan, Adrian and Curtis for helping. ... View more
