I would  use the definition query.  Just make it simple and use a wildcard like function for contours ending in 0 (zero) something like [Elevation-Field] like '%0'  or [Elevation-Field] like '*0' whatever your elevation field is.  This will look for all the contours that end in 0 or whatever number you put in there. The % sign and the * are wild cards.  * works for geodatabases and % works for shapefiles and or SDE I forget which. If one does not work try the other., Thanks for the responses so far, I take it I need to use the 'Definition Query' function in Properties when right clicking on the contour layer? 🙂 ... View more

In an edit session it is the little tool that looks like an black arrowhead.  If you hover over it then it will highlight as Edit Tool.  Outside of an edit session you can use one that looks like a square that is half light blue and half white.  It has an arrow running diagonally though the lower left corner.  If you hover over it the popup will say Select Features. Once you get a little more advance you can add other selection tools like Select by Lasso Select by Circle Select by Line Select by Polygon Select by Rectangle You can also try Select by Attributes or Location.  But those may be a little more tricky than this particular situation requires. If you use one of these tool you can select any single feature in the ArcGIS session.  However, you need to have the layer selectable. I would suggest runnig through some of the tutorials that ESRI has available.  One of them should detail on how to select features using the various tools on ArcGIS. Robert: What do you mean by "Selection Tool"?  I don't see an ArcMap-like tool to select only some of my features upon which to run the buffer tool. Please do enlighten! ... View more

Or pull them both into Access and do a unmatched Query.  However, this will only result in a tabular answer. The first suggestion is the one I would run with as the quickest answer. Model builder is not the solution here.  Just to cumbersom for this small of a task. Do the join and keep all.  Before hand you can create a new attribute.  once it is joined you can perform a query to find those that are not null and field calculate to put in a designator saying it exists in the shape. If they have a common unique ID attribute that matches in both databases, then a standard join and a selection where the FID of the shapefile IS NULL will get you the answer of which IDs do not exist in the shapefile that do exist in the geodatabase.  However, for the set that did match on the common ID, this won't tell you if they have changed geometry or other attributes, so it is not a complete comparison. If the only relationship is spatial it is nearly impossible if they are complex polygon shapes that have to have identical geometry.  Line geometry is also difficult to process, but with an advanced license there are some tools that make it much easier.  Points can use Spatial Join, provided there is no overlapping points in a the shapefile. So what constitutes a match for your data? ... View more

Or use the selection tool and and select the feature to be buffered and it will only buffer what is selected. Tami: Still somewhat tedious, but you can zoom in on each station so only one is visible in the map frame then run the buffer tool making sure that the Use Current Map Extent option is check on.  That will buffer features only found in the current map extent.  See attached.

Your best bet is to try and find street centerlines that you can bring into your map.  then join the address points to the centerline that is closest to it to create a new point feature. Otherwise, if it is only 5000 points that need to be joined to the street names you should be able to edit that out in no time. I would suggest creating a separate street name column for the points.  then with a definition query make it so only points wiht a null street name are visible.  For your street name points make only the street name visible and with the exact same attribute name as the address point. then select points and street point and transfer attributes. or create a model that will update the selected street name in the address points based on the street name  point. Sounds daunting but you should be able to knock it out in a day or two. HI! I've been struggling with this problem for a few days now and would like some suggestions or advice so I don't have to edit over 5k records by hand. I have cad drawings of city lots (labeled by house numbers) and street names. I can import these into ArcMap without a problem and spatially join house numbers (as pts) to the corresponding lot polygons (Also- as you can see in the img, the house numbers are on the side of the lot adjacent to the street they belong to). I attached an image of what I want to do. [ATTACH=CONFIG]34264[/ATTACH] I imported the street names as pts into Arc as well, however I can't join these logically as 1:many since my "road polygon" is one continuous polygon. What I wanted to do was spatially join these by boundary eventually. What I need to do is somehow add these street names to the house numbers. I was thinking of adding polylines to the CAD dwg however this would take me a very long time and I wouldnt be able to ensure integrity of the new dwg. Does anyone have any suggestions? Thanks!! ...

Kind of against ESRI shipping any 3rd party items from a liability point of view.  If it is not something they provide support for perhaps they should provide a link for you to go get it or provide some sort of vehical. ... View more

Just buffer only the clusters I would like to show clusters of points, and then export this information into a feature class or layer. I have tried the buffer tool, which gave me the information that I wanted. However, I do not know how to only export the buffers that have the point clusters. In other words, I am tracking areas in a city where there are clusters of a feature. I want to show where these clusters are in order to streamline our workflow. Any tips? ... View more

use select by location. Select all the points in the smaller feature that intersect the larger.  Then do a switch selection.  you now have selected all the smaller point features that are not identical to the larger. I have one large point feature class and another smaller point feature class.  The larger FC contains most, but not all, of the features that are in the smaller FC. I would like to extract the few features in the smaller class that are not in the larger FC and append them to the larger FC, essentially  a union of the classes (but for point FCs, not polygons).  I would prefer to do this using attributes; the two FCs have some matching fields, but in this case, Select By Location is not precise enough (there are some matching features in the two classes that are not completely aligned with one another). Ideas? Maybe I am overlooking something, this seems like it should be pretty simple.  Thanks, J ... View more

Using the From Raster Tools under Conversion Tools in Toolbox you can export your rasters as polygons or points or polylines.  The exported point will retain the raster cell value. Hello I think this should be an easy problem. I have multiple rasters that I would like to assess on a pixel by pixel basis and create a new raster of just the maximum values. How would I accomplish this? I tried using the Local Tool Highest Position but that isn't what I wanted. Thanks Bruce Burwell Saudi Aramco ... View more

Switch to Classic snapping and hold down the space bar while tracking.  It disables snapping. Often I have found that the trace tool will not jump a gap in features, so you may have to manually place a vertice at a gap. The trace tool in ArcGIS 10.2.1.3497 does not work all the time, or is very finicky about it when it does.  I have been trying the whole day to encompass an area that is about 100 sq meters using the trace function from parcel lines so that I can create an easement.  However, no matter what I do, the trace tool never even shows that its tracing.  The few remote random times I do get it to start tracing, I have to pan around and this causes it to "break".  I have shutdown and restarted numerous times, and am completely frustrated at this point.  I even tried to use the old method (which worked all the time ESRI *cough, cough) of selecting what I'd like to trace and it still will not pick that it is supposed to be tracing that.  I've come to the point where I am drawing multiple polygons and merging them together, but still have not managed to finish off this area. I have checked for geometry issues and have checked to make sure that all nodes are snapped together.  I have also tried drawing a polygon in another layer in the hopes that I could just get that to work and then copy/paste/merge them.  No go on that either. Please fix your tools so they work the way they are supposed to. ~a frustrated GIS Senior Analyst ... View more

I work with non spatial data quite a lot and incorporate it into my GIS. The key is you have to have some sort of identifier to link that non spatial data to a real world location. Without some sort of relation to locate it to something in the real world the idea of using non spatial data in a GIS is kind of moot and I would ask why you simply don't use Access, Excel, or Word to display your data. Gaëtan/Sean, The dev team has tabular dataset support planned for the next major release in July and is interested in hearing about how you'd like Open Data to support this type of dataset. It would be great if you could please post some comments here about how you'd like to add and work with tabular data -- direct upload of a CSV, referencing a CSV by URL that is already on a web server, sharing directly from Esri Maps for Office, etc.?  Which are your most important workflows that you'd like to see supported? ...

If you do not have a start or end point how can you possibly calculate a route? does your data have weights built into it? Weights in this case would be used to determine the cost adder to go through a particular area.  If the pipeline is going through a flat area and not crossing any roads it would have a lower resistance.  etc... If it does not you may need to have to build in weights to get NA to calculate a route of least resistance. My main concern is knowing if network analyst tools can help me to find the shorts distance between three town from the 25 towns locations. Do I always need a reference or destination point? like for example closest facilities or best route. For example it will be easy to calculate de best route to get from town 1 to 4 or 25 and to 9 but for these I need to start at 1 and specify that I am going to 4, 25 and 9 or if I wanted to know the closest town from town 5 also have to enter the reference first and find the closest town based on distance. In this case where I don't have a starting point nor an end point. I have to compare each against all others and find three towns that are closer to each other than the others. What tool does these? ... View more

IF you create subtypes for your new feature class and the subtypes have the name of an existing symbol it should automatically symbolize it based on that subtype name.  Or you can create a custom symbol and give it the name.  However, then you would need to save that custom symbol everywhere else. Hi, I am developing a customized python script tool in arcgis desktop. An output feature class is created after running the tool. More than one field are added to this output. However, I want to automatically symbolize one of the multiple fields added (e.g., the first one) when the feature class is added to arcgis. A similar example in the spatial statistics tool "Hot Spot Analysis". After running the tool, two fields are added: "GiZScore" and "GiPValue", but "GiZScore" is the one automatically symbolized. Can anyone tell me how this is implemented? Thanks in advance. ... View more
