Have you tried ETGeowizard? It does all sorts of conversions, also Polyline to point (vertices), and it can probably also put the M-values into an attribute. Hope this helps, Kathi ... View more

Yes, yes, yes! Minimize and separate tables, please ... View more

You can also turn off the display of mini toolbars on the General tab of the Editing Options dialog box. Thank God I've found this thread, or my computer, monitors, mouse and everything might have gone right out the window! Seems like docking the feature construction toolbar and then turning mini toolbars off does the trick for me, it stays docked, at least for the moment. Quite obviously, those people designing new features (or should I call them annoyances?) for ESRI never actually work with any kind of data. They must think "Ha, wouldn't it be handy to have that toolbar jumping in your face every time you click somewhere?" Guys, just try to imagine writing a letter by hand while your toddler daughter tries to put a big dictionary right in the middle of your page after every word you write... Sounds like great fun to me, very productive, plus you're sure to score 100% on calligraphy... ... View more

If I add the shapefile directly to ArcMap (no symbology applied), I can snap to it. But not if I use the .lyr file. Must be something wrong with that, then... ... View more

You will need to merge your shapefiles and then build a new map from that. For starters, you can move the data between different mxd's using drag-and-drop or by right-clicking>copy, then "Paste Layers". Now, using ArcToolbox, search for a tool called "Merge" (I think it's in Data Management, but I'm not sure any more) and use this to merge the county-Shapes into a new State-shape. Important: If the attribute tables of the county-shapse have identical field names, this will work well. If the field names don't match, you'll end up with empty fields and missing information, so you might want to check that first. ... View more

I have no idea whether this behaviour is relaed, but every now and then, my table of contents goes completely grey (like the background of a window with no content). Clicking anywhere in this grey area will reveal the one layer at the clicking location but not the rest of the TOC. I have to switch between the different tabs of the TOC to have its appearance return to normal. (This is in ArcView 9.3) I put this behaviour down to ArcGIS not redrawing the screen properly upon certain actions. (Same as lines dissapearing from the attribute table when you save edits, for example.) Not that this is going to help you, I guess... ... View more

could it be that your polygons have self-intersection resulting in tiny additional slivers or minute holes that make the buffer tool stumble? ... View more

Interesting idea, I would have thought all those people working with floorplans would use CAD software. But I guess you could do the same thing in GIS. You would have to make sure you have a watertight data model before you start. I don't see too many problems putting a single level of a building on GIS, or even several levels. But I'm not sure how I would go about those features that connect those levels, like stairs. I'm also not sure how I would model a door to show which way it opens. I guess it also depends on what you eventually want to be able to do with your floor plans: does it suffice to know Mr. Smith's office is in Miller Hall, 3rd floor, room 302, or do you need to plan fastest evacuation routes etc.? Is the end product a piece of paper or an online application? Who are the users, what level of knowledge do they have or need? How detailed do the floorplans need to be? Hope these questions and thoughts help point you in the right direction! ... View more

... After the poster has drafted it, she could be presented with a synopsis of closely related materials already in the forum and asked to indicate which, if any, appear to be related.  Links to those could appear with her initial message.  ... If these links would work cross-language then they would cover exactly what I mentioned earlier in this thread about double-posting in different forum sections. ... View more

Every thread has a unique and somewhat human readable and RESTful-style URL.  Nothing stopping the original poster or anyone replying to include links into both of the threads to cross-reference them to the other. Not sure that's a task we can always count on a moderator to do, due to the obvious language skill needed. Great idea though, of course. I can fully understand the language problem. Maybe one could include an invitation to cross-reference in the "code of conduct" (if there is such a thing, I don't know). ... View more

I've no idea if this would be feasable or not, but recently I've experienced several times that someone posts a question in the German Forum and the exact same question - in English, obviously - in one of the English fori. I think it would be helpful to have a link between these two, so anyone considering posting on one thread can quickly check if there is such a "sister thread" and if maybe the question has already been answered. At least the poster should have the ability to mark a question as answered or no longer relevant (even if there was no answer to it). ... View more

Open the attribute table and highlight the column in question, then click on the "Options" button at the bottom of the attribute table window. You'll find the option to search or search-and-replace there. I think you have to be in an editing session, but I'm not sure about that. Hope this helps. ... View more

Nobbir, what you say is correct, but I think you haven't quite understood the problem. Look at the screenshot in Johns first post: It should be clear that there are roads that have been photographed and others that haven't. In the absence (I assume) of any kind of list stating which roads haven been covered and which not, John wants to use GIS to filter the roads according to photo coverage so that he can find "holes" in his coverage and plan further photo routes accordingly. Call that process "filter" or "see, which ones" or "selection process" or whatever you like. You have hit the point that photos near (or at) road junctions are the tricky ones and it's definitely not clear which road segment they should be assigned to. But if you think of the process - you drive along a road and take photos every 10 m, obviously also taking shots on or near intersections - I think in this case it's irrelevant which road you assign the intersection shot to. I would simply exclude those and concentrate on the ones that one can clearly assign to one single road segment. To account for the above-mentioned uncertainty in GPS points and road data I suggested to use a reasonably-sized buffer for the selection process. Yes, it's all about translating an idea or action from everyday life that seems quite simple into a GIS environment. Whether you use the "correct" terminology (if it exists) to describe your problem is in my eyes quite secondary. But to translate the issue into a GIS concept in a correct manner is the critical part - and the part that makes working with GIS interesting. ... View more
