HI Tim Pro does have hatching, and an improved range of options I think. 1. Open the symbology pane. 2. Right-click on the colour/feature that you want the hatched symbology. 3. Select Format symbol(s) 4. The Format Polygon Symbology pane will open. 5. Select the middle icon (Layers) 6. Under the drop-down, select hatched (default is solid) 7. From there you can change the Pattern or Appearance. It really works very like a charm... Regards Mervyn ... View more

Hi Litan If you have access to the Spatial Analyst toolbox, one approach may be to convert each polygon to its own raster, then use the *Band Collection Statistics* tool to calculate the statistics for the set of 3 rasters. Make sure to tick the optional Compute covariance and correlation matrices option. The output is text file providing various statistics. The correlation matrix is useful in that you can now compare (via correlation) how similar each of the rasters are to one-another (and your "standard" layer). For a quick whirlwind tour of every tool in the Spatial Statistics toolbox, do watch this tech session video from last year's Esri User Conference http://video.esri.com/watch/4702/simple-ways-to-do-more-with-your-data-using-spatial-statistics Good luck.

Hi Antonio If you want to* create* a polygon shapefile from scratch, as your question was titled, then you need to run the Create Feature Class tool and* only provide the name of the folder where you would like the shapefile stored* under the Feature Class Location. Then provide a name under Feature Class Name (you can add the .shp extension if you want, but it will still create a shapefile if you dont), select Polygon as Geometry type (it is the default I think), select your coordinate system then hit run.

Hi Peter A crude solution may be to limit the cost surface to the road network only. You could buffer the road network by a suitable distance, convert to raster, and convert the non-suitable areas in your slope cost raster to NoData. I am not sure if it work but worth a try. ... View more

Are you saving output to a geodatabase? When I receive this error, saving to a geodatabase sometimes resolves the error. ... View more

Hi Tsan Yes, it is possible from what I recall. Do check out this ESRI technical video from the 2014 UC where this is demonstrated. http://video.esri.com/watch/3883/arcgis-pro-whats-new-in-mapping-and-visualization Regards ... View more

Hi Michael I think this can be achieved by using spatial joins. First you need to use a spatial join between the polygon and "all points" shapefiles. This will summarise the point values within each polygon. Next you can create a spatial join between your centroid file and the polygon file to get the summarised values from the all the points which would now be stored in the polygons. Not sure how familiar you are with spatial joins, so to start you right-click on polygon data, go Joins and Relates/Join.. then select the option to "Join data from another layer based on spatial location" The rest is really self explanatory but this process should work. Good luck. Regards Mervyn ... View more

Hi Jeremy Thank you for the explanation. I do understand and I will follow up with tech support. Regarding the fact that by design Pro's project packages include the entire geodatabase, regardless of whether the layers or data are actually included in any of the layers or layouts within a project, it would be nice if there was an option to only include data that is being used in the project. Perhaps there is an opportunity to do so in future releases. Regards Mervyn ... View more

Hi Jeremy Thank you for the response. I gather a "repo case to Esri support" would be a map or project package of my data to you or tech support? I am using ArcGIS Pro 1.1. I had not used ArcGIS Pro's packaging functionality before, so I tried to do so this morning to share the necessary file with you. I was eventually able to creat a very large project package (ppkx). I cannot create a map package because I am including my A0 map layout and doing so is only available under the project package option. For anybody else interested in this thread, do read he following helpful link for more info on various "packages" that you can create in Pro: Share a package—ArcGIS Pro | ArcGIS for Desktop A few notes to ArcGIS Pro developers ... ArcGIS Pro crashes if you do not have an internet connection and you try and create a project package. In Pro you have two options, (1) creating a project package and uploading to ArcGIS Online, or (2) creating a project package and saving locally. I repeatedly tried to do the latter without internet and it failed. I would naturally expect the geoprocessing tool to still run but only to provide for the save locally option if there was no internet connection. I realise that one of Pro's default options is to create a new geodatabase for each project. I don't do that and I provide each project with the default geodatabase. The problem is that when one creates a project package, it seem to me that the entire geodatabase is packaged up as well. Any file or link that is included in Pro's "project" structure seems to be included within the project package. For example, all my feature within this project probably amount to less than 500 mb if in the were in a "shapefile format". Bearing in mind a project package is a compressed file ... the project package that I created for you is over 3 GB in size. I am pretty sure my entire geodatabase is included in that file!. My geodatabase contain some sensitive information on threatened species hence I cannot share this map package with anyone.  So I need to know whether you have managed to recreate my map labeling and resolution problem when exporting to TIFF format, or whether I should go ahead and create an entirely new project with a new geodatabase that I can comfortably share with you to show the labelling problem I described in my first post? I may be wrong, and I apologise if I have misinterpreted the information at hand and unfairly critised ArcGIS Pro, but if I am correct, then I strongly suggest that a map package only include the features or layers that are included under the table of contents for the various maps and layouts within a project. Not the entire geodatabase. For the record, I really do enjoy using Pro ... most of the time. Perhaps we should take this discussion offline? I noticed your email address is not included under your profile, mine is, so please make contact? Regards, Mervyn ... View more

Hi William Try changing the font size on the scale bar, then the scale bar should re-size automatically. Regards, Mervyn ... View more

Hi Rebecca If one pays for the online streaming option, do you know if you can download the videos? One can do so from Esri's http://video.esri.com/channels  site? To me it may be worth it if I can download them and watch them again ... and again ... at a later stage. The tech sessions are a fantastic resource. Matthew, based on past experience, a limited set of technical presentations should be made available on above link in about October. ... View more
