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

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

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 ...

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 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 ...

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, ...

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 ...

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 another idea, by looking at the opposite angle to your question, to find centrelines first as explained one of the methods in here and then search for matching line features. Of course this approach will give robust results if the road lines are at the 'centre' of the polygons. Maybe adding thin ('how thin' is another issue of course) buffers to ...

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 ...

I'm going to suggest two alternative tools/methods to consider - both do require an Advanced license though, just like Near. Neither make use of buffers, as given the sheer number of records you're working with those would be complicated to work with in a spatial capacity without using a model and iterator. The Near tool only finds the single nearest ...

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 ...

you can create your buffers, then use the Spatial join tool, with the join one to one option. In addition to the optional field statistics, you will have a count field. JOIN_ONE_TO_ONE —If multiple join features are found that have the same spatial relationship with a single target feature, the attributes from the multiple join features will be ...

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 ...

The function (Locate Features Along Routes) should locate any lines within the search radius without any need for buffering. Be aware that the function will give you results against both branches for the part north of the intersection, as both "legs" will be within the radius. The result will be a table with the from-to measures from your routes per object ...

One of the plugin frameworks (the Processing framework) that's used by a lot of plugins, including Buffer by Percentage, changed the structure of its files slightly starting with QGIS 2.5. Most of the plugins using this framework have to be adapted to work correctly with QGIS 2.5 and 2.6. A new version (0.2.1) of the Buffer by Percentage plugin was released ...

This can be achieved in several steps. Run a Spatial Join for your buffer polygons and road network layers (right-click the buffer polygons layer in the TOC and choose Join and Relates > Join). You will get an output polygon feature class which contains information on how many road features were located (even partially) within the buffered polygons. ...

I think you want to exclude the intersection of the buffer in the where clause. WITH subq AS ( SELECT p.id, p.name, unnest(ARRAY(SELECT q.name FROM w_point q WHERE p.id != q.id AND NOT ST_Intersects(q.geom, ST_Buffer(p.geom, 0.1)) ORDER BY ST_Buffer(p.geom, 0.1) <#> q.geom LIMIT 5) ) as name FROM w_point p ) SELECT ...
