How are polygons used to summarize a feature?
The polygons used to summarize the features, or portions of features, in the input summary layer. The point, line, or polygon features that will be summarized for each polygon in the input polygons.
What is the output polygon feature class in ArcGIS?
The output polygon feature class containing the same geometries and attributes as the input polygons with additional new attributes about the number points, length of lines, and area of polygons inside each input polygon and statistics about those features.
How to extract feature centroid in shapefile using FME?
Yes, you can use the CentrePointExtractor transformer which will return either the centre point of the bounding box, the centre of gravity, or any point guaranteed to be inside a polygon (not always the same as the centre point). I don’t know how you have feature code stored.
How to summarize a feature in ArcGIS Pro?
If the input summary features are polygons, specify an areal unit. Attribute field from the input summary features that is used for grouping. Features that have the same group field value will be combined and summarized with other features with the same group field value.
How to calculate the total area of a flood zone?
The total area of each land-use type in the flood zone can be calculated by selecting all polygons within the flood zone (using the Select Layer By Attribute tool, for example) and summarizing the area by land-use type (using the Frequency tool). Following is a chart illustrating the result of this calculation.
How are new polygons created in overlay analysis?
New polygons are created by the intersection of the input polygon boundaries. The resulting polygons have all the attributes of the original polygons. Overlay analysis is often used in conjunction with other types of analysis.
How are lines and polygons overlaid in ArcGIS?
In the illustration below, logging roads (lines) and vegetation types (polygons) are overlaid to create a new line feature class. The lines have been split where they were intersected by polygons, and each line feature has been assigned the attributes of both original layers.
