NIM047424 - Donut geometric effect will fail to draw all polygon parts when Method is set to True Buffer. NIM047606 - The Java PointPluginDataSource sample will cause ArcMap to hang and become unresponsive if two plugin datasource layers are added from the same directory sequentially (i.e. one after another rather than in one add-data operation). Buffers are proximity functions. When you use this geoprocessing tool, it creates a polygon at a set distance surrounding the features. For example, a buffer is a polygon or collection of cells that are within a specified proximity of a set of features. Buffers can have fixed and variable distances.

To change the shape of the line used to cut the polygon, click a construction method type on the Editor toolbar or on the Feature Construction mini toolbar.

Splitting is both easier and harder than polygon clipping. Easier because you only clip against a line instead of a rect or another polygon; harder because you need to keep both sides. Create an empty list of output polygons Create an empty list of pending crossbacks (one for each polygon) Find all intersections between the polygon and the line. shape file by using another polygon shape file (like using a cookie cutter) to create a new clipped version of the original shape file. If you use the selection method, you will come out with entire features, e.g., entire parcels, or entire road segments, so some of these may extend beyond the area you want.

Mar 17, 2016 · Basic ArcGIS for the amnesia-stricken student Posted on March 17, 2016 by jlhizzett As I’ve been moving through my Ph.D, the use of GIS systems has become increasingly important to process the data I have been collecting or have been given. I have a shapefile which seems to have a small polygon digitized on top of a larger polygon. I would like to cut a hole in the larger polygon the same shape (and location) as the smaller polygon. How can I do that? Do I use the "Create Cookie Cut" tool? If so, where can I find documentation on this tool? Thanks, Bob

Mar 14, 2011 · The Cut Polygon Features task can be used to sketch a line that will split one polygon into two. This is a tool specifically useful for parcel management. The sketched line must intersect both sides of the polygon feature to cut it. Polygons A polygon is a plane shape with straight sides. Is it a Polygon? Polygons are 2-dimensional shapes. They are made of straight lines, and the shape is "closed" (all the lines connect up).

With polygons, the Placing Linear Array tool enables you to place polygons in a line at any angle. This feature uses the Set Separation Distance tool. With lines, the Placing Linear Array tool enables you to place multiple lines as a single line without restriction. Create a new polygon layer named Buildings by going to Layer ‣ New ‣ New Spatialite Layer. Once the Buildings layer is added, turn off the Parks and Roads layer so the base topo map is visible. Select the Buildings layer and click Toggle Editing. Digitizing buildings can be a cumbersome task.

You now have two polygons. Select only the inner polygon and press the DELETE key. The Clip command is another way of using an existing overlapping polygon to cut the shape of the hole. When using this method, keep in mind that all editable features underneath the feature you are using to clip with will be clipped. Select the inner polygon. You can use ArcGIS editing tools to make a polygon representing the full extent of your map and cut a hole in it for the area that was precached. The resulting donut polygon is the area where tiles should be deleted. See Cutting holes in existing polygons for an explanation of how to cut a hole in a polygon using the Clip command in ArcMap.

Another question is how successful this will be - not that many roads cross a county without intersecting another road. This document describes a procedure that will help you to split a polygon dataset with a polyline dataset using an ArcView license and the functions available in ET GeoWizards.

Click Trace on the Editor toolbar palette. Click and trace along the existing line or polygon. As you are tracing, you can change which features are being traced by pointing to them and clicking or dragging. Regular Polygon Formulas. A regular polygon is a polygon that is both equiangular and equilateral. All sides are equal length placed around a common center so that all angles between sides are also equal. When the number of sides, n, is equal to 3 it is an equilateral triangle and when n = 4 is is a square. .

You now have two polygons. Select only the inner polygon and press the DELETE key. The Clip command is another way of using an existing overlapping polygon to cut the shape of the hole. When using this method, keep in mind that all editable features underneath the feature you are using to clip with will be clipped. Select the inner polygon. For any two simple polygons of equal area, the Bolyai–Gerwien theorem asserts that the first can be cut into polygonal pieces which can be reassembled to form the second polygon. The lengths of the sides of a polygon do not in general determine its area. However, if the polygon is cyclic then the sides do determine the area. But it could be useful to export the viewshed data alone, either in raster or shapefile vector format, for use in other GIS programs. More generally, the need might arise to convert a general raster image of an area into a polygon shapefile. You can do this with the Spatial Analyst extension for ArcGIS, but the two together are pretty expensive.
