You can get your feat geometry and create buffer using Topological operator. These code can use for you. double bufferDistance = 0.0; // Note: set buffer distance as you want. For eg:200 or 500 var featShape = feat.ShapeCopy as IGeometry; var topologicalOperator = featShape as ITopologicalOperator; var featureBuffer = ...

I had the same problem with a similar file and found that it was due to complex polygons and polygons that only contained NA values. In particular there were one or two countries in my case that were causing it to crash - you can see these by looking at where the zonal statistics data ended before it stopped. To fix this I: Deleted all polygons from the ...

As you only have 2 buffer distances, you could do this in 2 easy manual steps (if you had more buffer distances I would recommend using the code from Polygeo). Step 1: Use the "Buffer" tool to create a 6 km buffer around all your points. Make sure you set Dissolve to "None" Step 2: Use the "Multiple Ring Buffer" tool to create a 6km buffer around the ...

To do this I think that you will need to use ArcPy with: a Search Cursor to read the geometries of your points one at a time buffer each point geometry twice (6km and 12km) and then use the 6km buffer to erase (using difference) from the 12km buffer to create an annulus polygon. an Insert Cursor to write a new polygon feature class for your annulus ...

Original dataset showing flood depth and polygon I've created along it: Let's produce points on the boundary of flood plain using flood level raster called RL, raster calculator plus some tools: Next - assign proximity areas to above points and convert those areas into corresponding flood level: Final step using raster calculator to define flood ...

Using QGIS and the Multi-distance buffer plugin, your buffer zones around the locations of traffic intersections would be non-overlapping, and each zone would be identified in the attribute distance by the distance to the outer border of the zone. That means that you can do a simple spatial join or point-polygon overlay to get the buffer zone added to your ...

I would go as below- Use "Dissolve Option" to "ALL" in "Multiple Ring Buffer" tool. Split this buffer layer into several layers by buffer distance- have a look here if needed. Use CountFeatureWithinLocation tool where "Search Radius" is set to "Zero". It create a field in the "Input" Feature's table that shows count. N.B. Give feedback if needed.

Adjusting with what @Vince was saying... Buffer does not accept an array in its out_feature_class property. However, you're kind of on the right track with a for each loop. Taking part of your code, here one way to do it. I am using a List instead of an Array because I don't care about memory usage and initializing my Array properly. There are numerous ...

I believe this tool will accomplish what you are trying to do. From description: "Converts closed polygons (commonly used for representing roads and rivers) to centerlines using the Thiessen polygon method. There is a Densify Distance parameter that you will likely need to adjust to optimize your results. Some post-processing editing is probably also ...

This is the script that solves the problem. Credit and many thanks go to david_p who wrote it. I just added a few missing parentheses. import arcpy, math, gc # Workspace, overwrite arcpy.env.workspace = r"YOUR_WORKSPACE" arcpy.env.overwriteOutput = True # INPUTS objects_input = "objects.shp" # must be polygons objects = "objects_lyr.shp" ...

Can you work with arcpy in Python a little bit? You could use some script to generate these zones in specific direction. I made some similar few weeks ago, I could post part of my script to help you. import arcpy, math, gc # Workspace, overwrite arcpy.env.workspace = r"YOUR_WORKSPACE" arcpy.env.overwriteOutput = True # INPUTS objects_input = "objects.shp" ...

Option A: Create the buffer using the buffer tool Select all the features in Buffer feature class Use warping tool and designate some important corners and perform warping Option B: Create the buffer using the buffer tool Enable Editing and Select all the features in Buffer feature class Use 'Move' tool, fill the X and Y offests in the window and ...
