The boundary input must be area features.If unchecked, all features in both the input layer and the layer to be summarized will be analyzed, 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 those features in the input layer and the layer to be summarized that are visible within the current map extent will be analyzed. If Add minority, majority is also checked, two additional fields are added to the result layer listing the percentage of the count of points, total length, or total area that belongs to the minority and majority values for each feature. When Add percentages is checked, a new field is added to the result table listing the percentage of the count of points, total length, or total area within each feature that belongs to each value from the group by field. The fields list the values from the group by field that are the minority and majority for each result feature. When Add minority, majority is checked, two new fields are added to the result layer. The minority and majority values are the least and most dominant values, respectively, from the group by field, where dominance is determined using the count of points, total length, or total area of each value. The Add minority, majority and Add percentages check boxes are enabled when a group by field is entered. A summary table listing each feature and statistic by group by field value is also created. When a group by field is selected, the pop-up for each feature in the output layer contains charts showing each summary total and statistic by field value. Optionally, you can select a group by field so that statistics are calculated separately for each unique attribute value. You can view the summarized data in the result layer's table or pop-ups. Each time a Field and Statistic are entered, a new row is added to the tool pane so that more than one statistic can be calculated at once. There are five options for statistics that you can calculate on numeric fields in the layer to be summarized: sum, minimum, maximum, average, and standard deviation. Standard setting) or Square Kilometers (Metric setting) Standard setting) or Kilometers (Metric setting) If you are aggregating into squares, the bin size is the height of the square, which is equal to the width. If you are aggregating into hexagons, the size is the height of each hexagon and the width of the resulting hexagon will be 2 times the height divided by the square root of 3. The bin size specifies how large the bins are. You can provide the area layer to use for analysis, or you can generate bins of a specified size and shape (hexagon or square) into which to aggregate. The inputs for Summarize Within include one area layer that serves as the boundary for summarizing features and a point, line, or area layer to be summarized.
See the Mixed-use development case study for the complete workflow. The company can use Summarize Within to summarize the qualifying zones within the city's boundary to find the total area of potential development zones. See the Districts with low income families case study for the complete workflow.Ī development company is considering creating a mixed-use development in an urban center. The Summarize Within tool is used to determine the number of low-income families in each college district so the cable provider can choose an appropriate district for its pilot program. See the Facility inventory by district case study for the complete workflow.Ī cable provider is starting a pilot program in which it provides low-cost internet access to low-income community college students. The Summarize Within tool is used to count the number of streetlights and miles of bike routes in each district so that the projects can be prioritized effectively. The Summarize Within tool calculates statistics in areas where an input layer overlaps a boundary layer.Ī city has a backlog of maintenance projects and wants to involve the maintenance assessment districts in projects related to streetlight and bike route maintenance. It will be available in a future release of Map Viewer. This functionality is currently only supported in Map Viewer Classic.
