Dear all We feel a need to save data in the NIS, for which there are no Feature Sub Type (FST) in the standard schema. Example (EEZ): The EEZ is a Polygon in the NIS. But we build the polygon from a Line, that is defined in our national legislation. To make sure we preserve the original data we would like to save also the EEZ Line feature in the NIS. Esri have placed the EEZ polygon in: "RegulatedAreasAndLimitsA (50) 'EXEZNE' Exclusive Economic Zone" Obviously a line can not be saved in a polygon feature layer, and the other obvious option: RegulatedAreasAndLimitsL have no FST for EEZ Question: Can I just invent a FSC and decide that I want to use e.g. no. 500 for it: "RegulatedAreasAndLimitsL (500) 'EXEZNE' Exclusive Economic Zone" If this is the way forward, could we (the Esri community) agree to always use e.g. 500-600 for 'local use', so I don't risk future conflicts? Or, should I rather use UserDefinedFeaturesL and e.g. invent "UserDefinedFeaturesL (2) 'EXEZNE' Exclusive Economic Zone" Any body have any experience here? Are there any 'best practise' to be pointed out? Best regards Martin

I'm talking about the latter: ...or, for spatially coincidence features there is the Duplicate Geometry check: http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#/Finding_duplicate_geometry/010200000022000000/. But this check assumes that the 'duplicates' are in seperate feature layers. My 'duplicates' are all in the same feature layer - and they are not found by this check. Best regards Martin

I need to check a if a point feature class contains any double (or triple) points. The points initially come from a number of sources, and have been merged. There is a chance that the same point was in several of the original feature classes, and therefore now exist in multiple copies. What data reviewer check can I use to check for redundant points in a feature class? Best regards Martin PS I use 10.1 and the data are in a NIS data base, but that is unlikely to be relevant...

I have exactly the same issue. If I import the same data into a file geodatabase there are no issues. Do I really need to unregister my data as versioned? That will create other issues for me because we replicate our data to another SDE geodatabase for our users. Any suggestions would be great. You can't "Version" a file geodata base, only a 'real' SDE data base. That is why you don't have the problem the second time.

There are no way arround. You can't create a topology in a versioned data base. Sorry.

Thanks Michelle Your RE. is perfect, thanks for that. Also thanks for the link. 🙂 Martin

Dear Forum I???m trying to use Data Reviewer to catch invalid dates in a string (TEXT) field. I use the "Regular Expression Check Properties" in "Table Checks". My field holds date values of form YYYYMMDD, e.g. 19660313 I tried to write a Regular Expression to fit this, some thing like: ([0-9][0-9][0-9][0-9])(0[1-9]|1[0-2])(0[1-9]|[12][0-9]|3[01]) But Data Reviewer keeps returning all records as errors, so obviously I???m doing something wrong. Can anyone help me to a good R.E. expression, which would identify only the dates that do not match the YYYYMMDD format? Best regards Martin

I very much would like to have this overview... 🙂 Martin

do you have an ArcInfo license? All have ArcGIS on the computer. Some have version 9.3 others version 10. Some have ArcInfo others less. It would be optimal if the solution could run on an ArcGIS9.3/ArcView license, or higher. If your solution requires specific license levels or extensions it is okay, though not optimal. Most Universities have campus licenses tith 'all included'. 🙂 Martin

We are a project, between some European Universities, and we lack a small helper script. Some of us could do the script, but don't have the time (budget), others are not programmers. Therefore we are looking for somebody who will do us a favor, for the fun of it. The Problem. We need to do analysis on many points, the analysis include buffering. Since the points are often much closer than buffer distance, the buffers hugely overlap. As they cut each other the number of small fragmented pieces explode. Partly Solution. If we can process the points in groups we could solve the issue. Each group, which is a sub-set of the original point swarm, have no points closer to each other than 2 buffer radi. This ensure no overlapping buffers, while processing this sub-set. Problem eliminated! Your Part. Write a script that reads a point shape file, and outputs a number of new point shape files. All points have to be preserved, with all attributes. Each output file will meet the requirement that no points in the file are closer than 2 buffer radi, Input files can contain several millions of points, though more likely 100.000. Buffer radi is 1km, but must be relatively easily adjustable. Salary We can't pay you any money. But we will credit your for being a superior programmer, as well as our friend.
