You're almost there! Using the standard buffer tool, enter your desired distance as a negative value, then set the line_side parameter to OUTSIDE_ONLY. This will generate areas inside of each polygon, giving the nice look of country borders on a political map when combined with a transparency setting: Taken from my other answer

Super simple. Change side type to 'Outside Only' and you got it:

I did not know that the FID was not preserved by this tool. Strange. As Chris recommended, calculate a unique ID for each point before you use the buffer tool. The unique ID I use for all my points is a concatenation of the X and Y coordinates in a text field I call XY_LINK. You should be able to create a join field without creating any new feature ...

This really depends on a number of factors. Are you talking about a large number of features? Do you have 100 neighborhoods and 1000 point locations, or a thousand times that number? Is your precision requirement high enough that you'll need to take Great Circle calculations into account? At less than 10 miles the error will be around 10-30 meters, ...

To determine what the river currently is outside the existing river use Euclidean Allocation to 'spread' the value of the river out. Then add the river rise value and select cells less than that: RiverSmear = EucAllocation(Rivers,Arbitrary_Distance,RiverElevation) RiverRise = RiverSmear + HowHighTheRiver NewRiver = Con(DEM < RiverRise,1,0) If you don't ...

You may want to use a Geometry Service on your server to accomplish this. See the example here: https://developers.arcgis.com/javascript/jssamples/util_buffergraphic.html That will allow you to create a buffer that's the same shape as the geometry you're creating a buffer for. However, it is possible to create a circle based on a polygon because a polygon ...

To do this in turf, you would do the following: // assume neigborhood is a geojson polygon feature // assume pt is a geojson point feature var turf = require('turf') // < require turf if you are using it from node.js var buffered = turf.buffer(neighborhood, 10, 'miles') var isInside = turf.inside(pt, buffered) console.log(isInside) If you want to do ...

Change your toolbox to Advanced interface. The tool v.buffer.distance is in the GRASS vector tools: These screen grabs are from QGIS 2.6.0 (Brighton) but it works the same in QGIS 2.0.1 (Dufour). The Doufour toolbox for v.buffer.distance resembles the link shown but the new one is slightly different.

This is just an idea it would need further experimenting as it may be flawed? How about looking at some sort of ratio value of length/perimeter? Imagine you had a line that is 10m long and has its full buffer which you had buffered out by 2m then the perimeter of the buffer would be approximately 20m. so 10/20 = 0.5. Now imagine you had a line that was ...

When you ran the Buffer tool you let the workspace to the Output Feature Class default to C:\Users\Cezar_ka\Documents\Default.gdb so you should be able to use the Catalog window to locate your roads_Buffer2 feature class to drag and drop it onto your map (or Table of Contents). My recommendation would be to choose a specific workspace for your outputs ...

This question is a year old but this alternate solution may be helpful to others. If you are using the Popup class you can set the Popup to a global variable so that you can set it not to show the window while updating. To prevent getting the "No information available" window, just set visibleWhenEmpty to false and hideDelay to 0: var popup = new ...
