It definitely is different that the previous help.  Much more context for how processes work.  However, more to wade through compared to the old when already knows the process and is just trying to find one specific setting.  But that's a minor drawback. Chris Donohue, GISP ... View more

Some questions/ideas that may help elucidate things: What version of ArcMap are you using and what license level?  I ask as the available tools vary considerably depending upon what version and license level you have.  Also, the Python version typically changes with ArcMap version. Is the source data in a File or Personal Geodatabase, Enterprise Geodatabase (SDE), shapefile, etc?  What format are you writing the outputs to?  The Calculate Areas task may be unnecessary if your data is going into a geodatabase, as it updates automatically. For your Question #2, the way to make it a feature class again so you can run Calculate Areas against it is usually via the Copy Features tool.  Here's the quote from the Make Feature Layer Help: The temporary feature layer can be saved as a layer file using the Save To Layer File tool or saved as a new feature class using the Copy Features tool.

Visual of some potential issues specific to the image you posted: Chris Donohue, GISP ... View more

Based on the image you provided, I'll throw out a guess as to what the issue is for the one you provided.  It appears the Destination that is highlighted is on a divided highway, with one-way traffic flow.  If the data is for a country with left-hand drive (like the United States), the segment it is on is going "South".  At least given the image shown, there is no way to reach that destination given the only segment visible is one-way away from the destination - i.e. the destination is "North" but the only segment near it goes "South". Also, the traffic lane going the other way also appears to be reversed from the expected travel direction, at least the arrows on your data make it seem so that way on the last segment approaching the Destination.  It appears the directionality of that segment is reversed from all the other segments - it is going "South" while all the other ones connected to it are going "North".  So traversing the network to the point the other way (via the "Northbound" lane will not be workable either (and this will defeat a search or snap distance to some extent). And if your data is for a place like England, my apologies for the fact that the Brits do everything backwards... Chris Donohue, GISP ... View more

Bruce: I'm curious - are the 10.x locators using a different process that produces better results?  I only know bits and pieces of this.... Chris Donohue, GISP ... View more

This gets a bit trickier, then.  It sounds like the issue is likely that different departments use the enterprise license to different extents, so is not as simple as "we have 10 departments so the total license bill is divided by 10" approach to paying for the license. Some possible approaches: - More usage equals more cost.  However, I'm not sure what tools ESRI has to check usage.  There might be some in the ArcGIS SDE Administrator tools and other areas. - Certain functionality of an enterprise license may only be used by one Department.  They pay more to cover for that.  For example, only one department uses the Network Analyst Extension, so they toss in more to cover that.

To tag onto the idea Darren Wiens posted, you may want to explore the advantages/disadvantages of having an enterprise license.  Having this information formulated will help buttress your choice - it is not uncommon for decisions on funding to be questioned.  What does your organization use if for, and what are the alternatives?  Does it serve your organizations needs?  Is it sufficient or insufficient for what is currently needed and what is planned in near future?  For example, what if the organization changed to just ArcGIS Desktop licenses - would that impact things?  For better or worse? Also, licenses vary, so you may want to provide some specifics on what your enterprise license currently includes.  This will help the GeoNet folks you are appealing to in providing good examples that match your situation. ArcGIS Platform | Pricing If it is determined that an ESRI enterprise license indeed is very valuable, you may additionally want to talk with ESRI for suggestions on helping to explain the value.  They may have already developed resources that you may be able to tap into.

To elaborate upon the suggestion by Darren Wiens ,here's how you check the Results for errors or other informational messages: Here's the Results windows that comes up.  Click on the plus signs to expand.  Drill down to the specific run you did and then expand the Messages.  If there is an error, there will be red x's.  Oftentimes the Error message will have a link to further explain the error (though admittedly some links just say you got a generic error, which isn't much help).

Some ideas: With Iterators, all the processes will get run each time it iterates.  So the solution here is typically to break the functions up into separate models and then link them with another model. The Build Network probably only needs to be run once, so break that out into a separate model (Model 1). Based on what you are trying to accomplish, the iteration looks like it should be run against the apartment shapefile.   Most of the processes will be in this model (Model 2). Not sure with your specific tests, but if you find that running the Solve for each apartment to then find both the closest farmers market and the closest grocery store doesn't work in a single model, one solution may be to create two models - one that iterates apartments to find closest farmers markets and then a separate model that iterates apartments to find closest grocery stores (so maybe Model 3 besides Model 2).  Caveat - if there is a correlation that I am not seeing where the closest grocery store influences in some way the closest farmers market chosen for the apartment searched, then there may be additional changes needed. To tie multiple models together, you can create another model - the "main run model".  When in Edit mode in Modelbuilder, drag in the existing models into this model from ArcCatalog.  Then connect them.  Make the inputs and outputs Parameters so the information will be "share-able" between the models.  Preconditions can be set to ensure they trigger in the correct order.  Once you have all this set up, to run the process you would run this "main model run", which will then run all the other models (Main Run Model).

I'm not sure exactly how GenMentors are able to count their experience towards GISP certification, but generally there is a process in the GISP application to capture that experience.  I believe it is under the heading "GIS Volunteer experience" in the "Contributions to the Profession" area in the Applicants Procedure Manual.  However, review the whole document to see if your experience might count in a different area (the requirements change from time to time).  Also, be sure to note the documentation requirements so can have the needed information ready for when you do the application.

To state what Jay Sandhu is saying in a different way, is there a specific set of goals you are trying to achieve?  For example, an advisory or regulatory limit on how fast apparatus can respond?  I mention this as our City's Fire Department has a set response goal time they want to meet, and since our City is growing, they are constantly re-evaluating their coverage so they can see if that goal can continue to be met.  Additionally, they need to plan out new Fire Stations so the new developments can also be covered while continuing to provide the same (or better) response times to existing areas.  So knowing the goals and the context that goes with them is critical to formulating a good analysis.
