Sorry, Eric, there is no tool in ArcGIS to permanently re-order fields. Although it has been much requested, I understand there are some technical difficulties in maintaining integrity with relationship classes, networks, etc. There are some workarounds, depending on how much data you have and any dependencies between feature classes. There does not seem to be a way without creating a new feature class. If you have stand-alone feature classes, you could create an empty template feature class in a file geodatabase that has the fields in the order that you desire, and then make one copy for each feature class you want to rearrange. Then you can load your existing data into the new classes. About loading data into existing feature classes and tables—ArcGIS Help | ArcGIS for Desktop I believe there is also to a way to "rebuild" any relationships if you have relationship classes. A third party app, ET GeoWizards, will reorder shapefiles. It will create a new shapefile (with a different name). Some of the ET GeoWizard capabilities are not free, but the reorder fields is free. Hope that helps, Cheryl

Duh! Sometimes you forget the simple things -- it simply needed a reboot! Thanks all, for the help. Cheryl

Thanks for the ideas. I'll try these out when I get a chance.

I recently installed ArcMap 10.3.1 to a new computer on a network. I have a map in a shared location which shows the correct symbology on my computer (which also has 10.3.1), but when the map is accessed from the new installation the symbology is all messed up for point features. For example, a fire hydrant showed a large number "4", whereas it is supposed to be one of the symbols that looks like a fire hydrant. If I search for fire hydrant in the symbol selector, the options are all wonky and include this number "4". Any help in knowing what's going on and how to fix it would be greatly appreciated. Cheryl

I would second this recommendation. I found it to be a fun, face-paced, challenging course. It was a single course when I took it, but now they have broken it into two--not sure if the time frame is a little more relaxed.

Guess that's why I am learning Python! Thanks to both Johannes and Scott for your responses. I think I'll go the Python route.

I have a model which iterates through a dataset, renames the shapefiles in the dataset and puts the new name of the shapefile into a "source" field in the shapefile. (The new name, used both in Rename and Calculate Source, is '%Name%_%Date%') When I run it in the Model Builder window, it runs fine. When I run it outside of model builder as a tool, it renames the first file and incorrectly calculates "source" as the new name of the second file, and it renames, but doesn't put any source, in the second file and then errors out saying the first renamed file already exists (which it does because it already created it). Why is it trying to rename the first file again? And why is it putting the new name for one file into the source field for another file? I thought the iterator takes the first file, runs it through the rest of the model, then the second file, and so on. At least that seems to be how it runs in Model Builder. At any rate, how can I fix this. I need to be able to run it as a tool outside of Model Builder.

Thank you Lauren, for your detailed reply. It really helped me. It turns out that due to small sample size, I am unable to use Getis-Ord Gi*, 24 positives out of 120 tested, scattered across 40 households (apparently I need at least 60). It looks like there is some tendency to clustering but I cannot visibly tell if it is different from the clustering of individuals tested. I used Kernal density on all individuals tested and on pos/neg individuals. The outputs are very similar, and changing the distance or using None, doesn't make a lot of difference except in the overall size of the "hotspot", except of course if the distance is so small that each house is a hotspot. From this I am concluding that there is no evidence for clustering. As an additional test, I conducted a Poisson goodness-of-fit test for the number of individuals in each household that were positive, trying to determine if the presence of one individual in a household that was positive made it more likely that a second individual would be positive. This came up "Not significant". I am not a statistician, so I am not certain that this is a valid test. Is the Poisson an appropriate test? I have another similarly sized dataset, that does appear to have clustering of positive individuals that is different from the clustering of individuals in general (i.e., that hotspots are not in the same location). From what you have already indicated, I think you are saying, "Let the maps tell the story." I cannot say anything about the significance of this, but I can say the maps suggest there might be something going on. The Poisson test was not significant in this case, as well. We have 8 more villages to look at, ultimately. Unfortunately, all of them have small sample sizes, but perhaps looking across the 10 different communities, we can visually get some idea if anything is going on. Are there any kind of significance tests that I could use with these small sample sizes? The data was collected several years ago for a different study and spatial analysis was not being considered at the time. Consequently, considerations for spatial testing were not made. We are just trying to use what we have available to see if a spatial component can be detected.

Hi Hunter, Wow! I'd given up on getting an answer! What you suggest is ultimately what I did. I haven't had a chance to work more with it to see how well it works--sidetracked by other projects Thanks for answering even though it was an old post. This one I think I have figured out, but there are others out there which I haven't. Maybe, someday, someone will find them and have an answer! Cheers! Cheryl

For anyone looking for a solution, follow the instructions in article: Geodatabase Attachments are not Automatically Included in the Output of Geoprocessing Tools http://support.esri.com/cn/knowledgebase/techarticles/detail/40289

Thanks, Tim, I have spent hours trying to find a solution, but I guess I never used quite the right search to find this! This looks like it should solve the problem. I won't be able to try it until tomorrow; if it works, I'll mark it as answered. Thanks, again, Cheryl

I have several feature classes for which I attached photos to points using the Attachment tools. I need to project the feature class to another coordinate system, but when I do the relationship is lost. If there were only one photo per point, I perhaps I could store the path to the photo as an attribute in the feature class table , but I have multiple photos for some points so that won't work. Is there any way to get the relationship class rebuilt for the projected feature class. Re-creating the attachments one by one is not feasible. If there is not a way, I am going to have to dump attachments, they are just too limited!

I have data from a village along the Amazon River, where homes were visited and individuals tested for having had particular disease. In most homes, all the people tested were negative but in some homes 1 or more people tested were positive. Determination of study area questions? I want to see if there are clusters of those that have had the disease, so I am trying to use the nearest neighbor tool. I have a question in regards to the calculation of the area for this tool. Most of the village is on one side of some fields, around the corner of an L-shaped road, but another group of about 10 houses is over 150-m away from any houses in the rest of the village, across some fields. In addition, one side of the village is bounded by the river. I am trying to find out the most statistically-valid way to define the study area which has resulted in several questions. 1. Since no houses will ever be in the river, should that be the boundary on that side -- if I use a convex hull to define the boundary, part of the village area would be considered to be in the river since the shoreline is irregular? 2. Should a do a boundary around the main part of the village and a second boundary around the separate group of 10 houses, and add the areas together; or should I make it a single boundary around everything? 3. Because of the arrangement of the village around an L-shaped corner, using a convex hull to define the boundary includes a lot of space with no houses between the arms of the L. Instead of using a convex hull, would it be appropriate to use a more L-shaped boundary to match the shape of the village, or is there a reason to use the convex hull? Getis-Ord Gi* questions If Average Nearest Neighbor does not indicate clustering, is there any reason to use Getis-Ord Gi*? The frequency of individuals that have had the disease is about 1/4 of all those tested. In more than half the homes have no one has had the disease, and no home has had more than two with the disease. Consequently, the frequency of homes with 0, 1, or 2 individuals who have had the disease is skewed towards homes with 0, definitely not a normal distribution. Is this appropriate data to use with Getis-Ord Gi*? If not, can you suggest a statistical test that would be more appropriate to analyze cluster in this data? Thanks, Cheryl

Finally I have hit upon a solution. If I reproject the feature classes that I want to export to CAD into a custom coordinate system in which the units are changed from feet to inches, then everything exports correctly. The seed file, as it came from CAD, didn't need any units changed. The block inserts exported at the proper size relative to the line features, without using a scale factor of 0.08333, and a 76' line in the GIS exports as a 76' line in CAD. If anyone knows a better way to do this, I would like to hear about it. Cheryl

I am having the same problem (see: https://community.esri.com/message/446321#446321 I am using a seed file because I am using block definitions for my point features. The drawing units in the seed file have been defined as: Length Type: "Architectural" and Units: "Inches" (or Length Type: "Architectural" and Units: "Feet"-which CAD clearly says it does not like), but the scale is still exported wrong in the CAD interface (it has correct lengths when viewed in GIS). Is it a problem with the seed file or the tool?
