Are you getting an error or is it just not doing what you want it to do? ... View more

edit: the following is to extract the word between parentheses. If you are looking to simply select features based on the word between parentheses, follow Jake's advice below. Using Python in field calculator: !Place!.split('(')[1].split(')')[0] Basically, split your original string by the character '(', take the second part of that, split it by ')', and take the first part of that. ...

I was being very tongue-in-cheek. I've generally had good support, although I have had a few dead-ends that required reinstallation, after prolonged sessions of shipping data back and forth, sharing screens, attempting to skip steps by showing I'm not a complete idiot (that never works), reconfiguring system, etc. ...

In experience, the flow chart goes something like: 1.) Do you have any third party tools installed? - Yes: uninstall those - No: go to #2. 2.) Do you have ArcGIS installed? - Yes: reinstall ArcGIS ... View more

If you're using python, I think you mean: def calculateRadius(x1,y1,x2,y2):    radius = (( x2 - x1 )**2 + ( y2 - y1 )**2)**0.5    return radius print calculateRadius(x1, y1, x2, y2) ... View more

Mike, Since you mention Network Analyst, would you please clarify whether you require the distance between points along a line (e.g. along a winding road), or the straight-line distance between pairs of points? ... View more

Thanks for pointing out this tool, Sephe (I wasn't aware of it). It solves most of the problem, but not the case where the point is not perpendicular to the line (see below), although that can be handled through other means. It's much easier to connect points to end vertices than to the line geometry itself. The script you linked to promises to do both cases, but I haven't tried it. ... View more

If you're asking because Basic and Standard licenses only allow two inputs for Intersect, you can get around it by running the tool once between feature classes 1 and 2, then again with the output and feature class 3. ... View more

Check out the Polyline object, specifically the measureOnLine method:http://resources.arcgis.com/en/help/main/10.2/index.html#/Polyline/018z00000008000000/ This will give you the measure of the point on the line, from the start of the line. Repeat for both points and find the difference. ... View more

Depending on how many polygons you have, this semi-manual method may be suitable. 1.) Run Intersect on the polygons as the only input, specifying line as the output type. This creates boundary lines shared between polygons. Unfortunately, there will be two copies of each line, one for each participating polygon. 2.) Dissolve the duplicate lines, turning off create multipart, and unsplit lines. Now you'll have one boundary line between polygons. 3.) Symbolize the lines as an arrow underneath a line. See below - I added an arrow layer in the line symbology as a character marker symbol from the Arial font (↑). 4.) Inspect your lines. They will be symbolized according to the line orientation saved in the shapefile. 5.) If a line is not symbolized in the orientation you want, start editing, select the line, edit vertices, right-click the line, and choose Flip. ... View more

Also, would it be possible to have rectangular pixel? I guess why not... Your pixels must be stored as squares, however you can trick ArcMap into displaying rectangular pixels on-the-fly by changing the data frame projection to one which introduces significant distortion. Of course, this doesn't help your case, but you should abandon the plan to specify rectangular pixels. ... View more

Not sure if this applies to 10.3 or not (I'm at 10.2.2), but see this blog post, which largely refers to this knowledge base article. TLDR summary: start a new MXD, add your basemap, add your unreferenced image, georeference. ... View more

Unfortunately, there are several warnings indicating that editing feature classes in Access is risky and may corrupt the geodatabase, such as: http://support.esri.com/cn/knowledgebase/techarticles/detail/31599 ... View more

Your first task is to get a polygon shape for Louisville (either from an existing data source or digitize it yourself). From there, you can apply Data Frame clipping through Data Frame properties (Data Frame tab) to display only the basemap (and all other data) inside the Louisville shape, and Select By Location the census data intersecting your Louisville shape. Regarding the basemap, if you're using a web mapping service, you can never fully extract the data, just change the display extent. ... View more

If you have Standard or Advanced licensing, use Snap. Make a copy first, because this changes the input data (no backsies). ... View more
