arcgis overlapping polygons in same layer

Access Case Notes on the Esri Support App!

The name of the output layer to create on your portal. The count of overlapping features is written to the output features. I can't have anything overlapping, because the area calculations will be off for the County (if I were to sum the area of all the different land uses and roads). The output is a planarized union of the inputs.

Please provide as much detail as possible. The geometry type of the output is the same as the geometry type of the input, with the exception of point geometry. For example, you may want to find all features that intersect a zip code, county, or city boundary, merge the data, and discard all of the others.

I have a polygon layer of roads (I buffered the roads to a certain width based on 3 road classes).

However, this file is pretty large, and I do not want to be deleting these segments individually. In this tutorial you will use the Overlay Layers tool to intersect and merge zip codes with different datasets in the Santa Monica Mountain area. Run the rules and they will catch /not allow overlapping polygons in the same layer. I have a layer with more than 5000 polygons .

Please try again in a few minutes. For example, with a map that has a polygon layer representing states and a point feature representing cities, use this to calculate how many cities each state contains.

I need a seamless layer that does not have overlapping polygons of different road classes. In the 'Join' dialog box, specify the 'Join data from another layer based on spatial location' option.

Use the Overlay Layers tool to intersect and merge the Zip Codes in Boundary and the Trails layer. The following code demonstrates how to use the CountOverlappingFeatures function to get the overlap count for three overlapping cellular service provider networks and use the min_overlap_count parameter to limit the output to only those areas where all three cellular service providers have coverage. Use the Map Viewer to create a Map Notes layer and manually draw a polygon graphic that can be used to intersect the Trailheads layers. Use the Map Viewer analysis tools to overlay, intersect, and merge features.

The count of points within each polygon is always returned. If you don't supply dissolve fields, polygons that share a common border (that is, they are adjacent) or polygon areas that overlap will be dissolved into one polygon.

There may be a way to do the analysis without creating buffers that end up looking bad.

Uncheck all of the layers to make them invisible except the Boundary layer. The quickest method is to select the poly that will do the clipping, go to the editor menu drop down, use the clip tool, and use the discard (default) option. Please rate your online support experience with Esri's Support website. The process is probably best to be done manually to clean up though. So if this is your dataset fabric, the time now manually to do this will pay off down the road. The output table containing records for each individual overlapping geometry. I know of, and have used the Count Overlapping Polygons model.

If two or more fields are specified, the values in these fields must be the same for the boundary to be dissolved. Cartography - Graphic Conflicts - Resolve Building Conflicts.

The tool requires an input layer (the layer you wish to extract features from), an overlayer layer (the layer defining the area to extract), and a specified overlay (merge) operation: intersect, union, or erase.

In the panel click Manage Data > Overlay Layers and select the following: In Contents, click Open Space with Zip Code > Change Style and select the following: In the map, click on some features and view the merged data.

How To: Remove overlapping areas of a polygon without using the Erase tool Summary. The polygon should represent an area that overlaps the trailheads that you would like to merge and extract.

Learn more about how to create Map Notes and graphics in the Draw graphics tutorial. I have tried this solution anyway, but due to the size of the input shapefile (more than 200 MB due to large extent and high resolution), it is not possible to make such operation.

Running Feature To Polygon on these 67 overlapping polygons results in 18,733 unique polygons with a maximum Join_Count of 65.

Use the Overlay Layers tool to intersect and merge the Zip Codes in Boundary and the Parks and Open Space layer. For example, with a map that has a polygon layer representing states and a point feature representing cities, use this to … All rights reserved.

The result is a new hosted feature layer. I tried to find an answer to this question but I didn't seem to find what I was looking for. Generates planarized overlapping features from the input features. | Privacy | Terms of use | FAQ. To count overlaps on these 18,733 polygons using the spaghetti and … ArcGIS Online includes a powerful set of tools for performing spatial analyses and managing data. It needs to match the actual area of the County.

I will try and incorporate that! However, because I did that, I have some roads that are overlapping each other.

A list of field names and statistical summary type that you wish to calculate for all points within each polygon. You could try Resolve Building Conflicts in the Cartography Toolbox.

Use the Map Viewer analysis tools to create spatial queries and extract features. Instructions provided include step-by-step instructions for adding a field containing a count of overlapping features in another layer. Be warned that this will clip everything that is visible and editable. In Contents, click Trails with Zip Code > Change Style and select the following: In the map, click on some trail features to view the merged zip code data. The following fields are included with the Output Overlap Table: This table allows you to relate each overlap back to the input and output features.

New comments cannot be posted and votes cannot be cast.

This operation can be accomplished in the Map Viewer with the Overlay Layers tool. For example, if you have a layer of counties and each county has a State_Name field, you can dissolve boundaries using the State_Name field. Features that participate in geometric networks can also be merged. Copyright © 2020 Esri. The following Python window script demonstrates how to use the CountOverlappingFeatures function in immediate mode. For example, if you have a layer of counties and each county has a State_Name field, you can dissolve boundaries using the State_Name field. Specify the location and name of the output feature. One or more fields from the input layer that control which polygons are merged.

Instructions provided include step-by-step instructions for adding a field containing a count of overlapping features in another layer. Overlay Layers performs the function of the Intersect, Union, and Erase tools.

The statistics include sum, average, minimum, maximum, and standard deviation. Content feedback is currently offline for maintenance. I only want to remove one of them.

This is what I originally was going to do, but I was hoping if there was somewhat of a quicker way. New areas are created where polygons intersect. When merging, you choose which feature's attributes are preserved during the operation.

Usually topology checking tools will spit out a list of errors under one category (ie overlapping polygons) and you can get a count and then click/zoom through the list to clean them up. Checking the Merge into a single COGO line check box ensures that the newly merged feature has a single straight line segment or a single circular arc segment. For polygon geometry, any area that is occupied by two or more features is considered an overlap.

Run the rules and they will catch /not allow overlapping polygons in the same layer. The overlay operation determines how features are extracted and how the attributes are merged together.

When an Output Overlap Table is generated, it includes one record for each overlap. Looks like you're using new Reddit on an old browser.

If you select line features with COGO fields and those features can be formed into a single COGO line, two extra options are available on the Merge dialog box. How can we make this better?

You will learn: how to use the Map Viewer analysis tools to overlay, intersect, and merge features. The overlay function splits features in the input layer where they are overlapped by features in the overlay layer. Overlap between vertically offset features (geometry with various z-values) is evaluated as if all features are flattened onto the same plane.
