An example of a spatial expression is that the parcel must also be within a certain distance of a river (Parcels within a distance of 0.75 Miles from Rivers).The Derive New Locations task is very similar to the Find Existing Locations task, the main difference is that the result of Derive New Locations can contain partial features.In both tasks, the attribute expression where and the spatial relationships within and contains return the same result. This is because these relationships return entire features.When intersects or withinDistance is used, Derive New Locations creates new features in the result. For example, when intersecting a parcel feature and a flood zone area that partially overlap each other, Find Existing Locations will return the entire parcel whereas Derive New Locations will return just the portion of the parcel that is within the flood zone.

summarize_within¶

analysis.summarize_within(summary_layer, sum_shape=True, shape_units=None, summary_fields=[], group_by_field=None, minority_majority=False, percent_shape=False, output_name=None, context=None, gis=None)¶

The SummarizeWithin task helps you to summarize and find statistics on the point, line, or polygon features (or portions of these features) that are within the boundaries of polygons in another layer. For example:Given a layer of watershed boundaries and a layer of land-use boundaries by land-use type, calculate total acreage of land-use type for each watershed.Given a layer of parcels in a county and a layer of city boundaries, summarize the average value of vacant parcels within each city boundary.Given a layer of counties and a layer of roads, summarize the total mileage of roads by road type within each county.

sum_within_layerRequired layer (see Feature Input in documentation): A polygon feature layer or featurecollection. Features, or portions of features, in the summaryLayer (below) that fall within the boundaries of these polygons will be summarized.
summary_layerRequired layer (see Feature Input in documentation): Point, line, or polygon features that will be summarized for each polygon in the sumWithinLayer.
sum_shapeOptional bool: A boolean value that instructs the task to calculate count of points, length of lines or areas of polygons of the summaryLayer within each polygon in sumWithinLayer.
shape_unitsOptional string: Specify units to summarize the length or areas when sumShape is set to true. Units is not required to summarize points.
summary_fieldsOptional list of strings: A list of field names and statistical summary type that you wish to calculate for all features in the summaryLayer that are within each polygon in the sumWithinLayer. Eg:[“fieldname1 summary”, “fieldname2 summary”]
group_by_fieldOptional string: Specify a field from the summaryLayer features to calculate statistics separately for each unique attribute value.
minority_majorityOptional bool: This boolean parameter is applicable only when a groupByField is specified. If true, the minority (least dominant) or the majority (most dominant) attribute values within each group, within each boundary will be calculated.
percent_shapeOptional bool: This boolean parameter is applicable only when a groupByField is specified. If set to true, the percentage of shape (eg. length for lines) for each unique groupByField value is calculated.
output_nameOptional string: Additional properties such as output feature service name.
contextOptional string: Additional settings such as processing extent and output spatial reference.
gis :: Optional, the GIS on which this tool runs. If not specified, the active GIS is used.
