IFC is an important open data format used in the construction industry and should be supported natively the way support is already provided for Revit within ArcGIS Pro. It is not as complex an integration but would have a huge impact on GIS in construction. Open formats like IFC are often adopted by government agencies in Australia as deliverable formats and giving Esri software the ability to read and write them natively will go a long way towards BIM-GIS integration at a project level. I whole heatedly support this idea and I am surprised there hasn't been more movement here.

I've been working through the 'update real-time data' example on :Update Real-Time Data with Python | Learn ArcGIS and have run into the same problem. The first tool the script accesses is arcpy.management.CreateFileGDB and that gives a runtime error "RuntimeError: Object: Error in executing tool" but it works within ArcGIS Pro. Initially I thought it was something to do with my setup as I've had problems with ArcGIS Pro licensing, so it is good to know I'm not alone.

Currently the symbol for unshared content in portal is a locked lock : Please change this as it is not intuitive and implies 'locked' content. It should be something like a red exclamation symbol

I wanted to find out if its possible to execute a tool and if the tool has a problem processing a particular feature within a feature class will through an exception, report the feature that it has a problem with, but at least will move to the next feature within the feature class and continue processing. Ok so from this I take you want to do 2 things: 1. Loop through each feature and report problems if they occur, and 2. Continue processing all the remaining features. You can narrow you exception reporting by doing the following: try:
# place your code here for looping through each feature
except Exception, e:
print "feature error: %s" % e
sys.exc_clear() You may want to consider writing out a text file to store these feature errors. The last line should allow the script to continue and is preferable to 'pass' Anyway without seeing you code it is difficult to provide a generic solution so you probably want to test this on a small dataset first. Hope it helps.

Has anyone had success using stacked charts in 3d analyst? I've added a point feature class from a file geodatabase to ArcScene - yep visible no problem I've created a join to a table in the same geodatabase - yep smooth sailing As soon as I try to symbolize the 3 fields using Charts>Stacked, the points vanish... I'm running 10.1, although I might as well be blind Interestingly this also happens in ArcGlobe

I have created a relate (1-M) to a table in a geodatabase but now would like to symbolize the data in the related table. I want to use the Charts (stacked) symbology to show multiple values over a single point. Is there any way of doing this in ArcGIS without adding heaps of fields to the feature table? I have always imagined (until now) that this was straight forward in ArcGIS but now I'm begining to doubt whether it's possible......someone please restore my faith! I might have to resort to expanding the feature class table to hideous proportions (ugly)....

At first glance I think you could solve the first part of the problem using Tarboton's 'Upslope dependance function' as this would give you an upslope 'catchment' for every grid cell. This would mean using the Dinf flow direction grid (which less restrictive than D8 (used in ArcHydro) in terms of angular direction of flow). However, this would mean computing it for every cell and for some cells this would be null (top of mountain). By the second part "downstream distance to a point grid" I assume you mean maximum drainage distance to a cell? http://hydrology.usu.edu/taudem/taudem3.1/index.html I'm still using version Taudem 3.1 on ArcGIS 9.3.1 Anyway, hope my comments help.

Hi Cadence, You'll need good topographic data, good river profile data, good landuse data as well and a good hydrologist who knows how to use HEC-RAS (a 1-D modelling that has a plugin for ArcGIS called HEC-GeoRAS). Also, you will need historical rainfall data as the sorts of flood boundaries you're interested in are statistically calculated. Doing this for a whole country using these tools and data is a big task so you're probably better off starting with a small part of one major river system. Hope this helps.. regards Colin Constance

Hi Jamie, I've been using TauDEM plugin (ver 3.1) for ArcGIS (9.3) developed by David Tarboton at USU. He has developed a number of specialist functions including 'Down slope influence' which does exactly (I presume) what you are looking for. It is limited to a grid size of 7000 x 7000 cells and it's accuracy is controlled by the accuracy of your DEM. I'm using it on 1-2m resolution LIDAR dems for culvert sizing. www.hydrology.usu.edu/taudem/taudem3.1/index.html It also has many functions that are similar to ArcHydro but is not really comparable. Hope this helps.... Regards Colin Constance
