The example below uses a 300-mile buffer around cities with populations above 10 million. Geodesic buffers may appear unusual on a flat map, but when displayed on a globe, these buffers will look correct. Distances are calculated between two points on a curved surface (the geoid) as opposed to two points on a flat surface (the Cartesian plane). Geodesic buffers account for the actual shape of the earth (an ellipsoid, or more properly, a geoid). The Create Buffers tool uses a geodesic method for constructing buffers. Limitationsīuffers cannot be created using a Euclidean distance. If unchecked, all features in the input layer will be buffered, even if they are outside the current map extent.Ĭlick Show Credits before you run your analysis to check how many credits will be consumed. If Use current map extent is checked, only the features that are visible within the current map extent will be buffered. Larger buffers in multiple-distance buffers include areas within one or more smaller buffers. Larger buffers in multiple-distance buffers do not include areas within one or more smaller buffers. Single-distance buffers around area features exclude the buffered features in the result buffers. Single-distance buffers around area features include the buffered features in the result buffers.

The right side of the line is determined based on the direction of the line from its start coordinate to its end coordinate and may not represent the right side of the line as seen in Map Viewer Classic.Īt the end of the line, the buffer is rounded.Īt the end of the line, the buffer is straight across. The left side of the line is determined based on the direction of the line from its start coordinate to its end coordinate and may not represent the left side of the line as seen in Map Viewer Classic.Ī buffer is created only on the right side of the line feature. Together into a single multipart feature, removing anyĪ buffer is created along all sides of a line feature.Ī buffer is created only on the left side of the line feature. When using Dissolve, all buffers are dissolved These defaults can be changed using the Options drop-down menu.įor any buffer that is on top of another buffer, the areas in common are kept.įor any buffer that is on top of another buffer, the areas in common are combined. When there are multiple input distances, the default is to create rings. When the input features are areas, the default is to include the input area in the buffer. When the input features are lines, the default is a rounded buffer on all sides of the lines. You can create a multiple-ring buffer using the Distance option by entering multiple constants separated by a space.īy default, the Create Buffers tool will create overlapping buffers when the buffer areas meet. The size of the buffer can be entered as a constant using the Distance option (all buffers will be the same size) or using values from a field (different features can have different-sized buffers). See the Mixed-use development case study for the complete The development will have to be conveniently located within a quarter mile of shops, restaurants, or a light rail stop. See the Proximity to schools case study for the complete workflow.Ī development company is looking to make some money by creating a new mixed-use development in an urban center. The council also wants to restrict new liquor licenses to buildings that are more than 1,000 feet from schools, parks, and libraries. In an effort to keep liquor out of the hands of children, the council decides to place regulations on advertising in liquor stores within 1,000 feet of schools, parks, and libraries. See Coordinate systems, projections, and transformations for more details.Ĭity council has noticed a high number of liquor stores per capita in the city. Uses mathematical formulas to relate spherical coordinates on the globe to flat, planar coordinates.
