Tasks contained in the GeoAnalyticsTools service

The GeoAnalyticsTools service contains a number of tasks that you can access and use in your apps. GeoAnalytics Tools are available in your ArcGIS Enterprise portal's Map Viewer, ArcGIS Pro, the ArcGIS REST API, and the ArcGIS API for Python. The categories are logical groupings and do not affect how you access or use the tasks in any way.

Tasks that summarize data

TaskDescription
Aggregate PointsAggregate Points diagram

This tool works with a layer of point features and a layer of areas features. Input area features can be from a polygon layer or they can be square or hexagonal bins calculated when the tool is run. The tool first determines which points fall within each specified area. After determining this point-in-area spatial relationship, statistics about all points in the area are calculated and assigned to the area. The most basic statistic is the count of the number of points within the area, but you can get other statistics as well.

Join FeaturesJoin Features diagram

The Join Features task works with two layers. Join Features joins attributes from one feature to another based on spatial, temporal, and attribute relationships or some combination of the three. The tool determines all input features that meet the specified join conditions and joins the second input layer to the first. You can optionally join all features to the matching features or summarize the matching features.

Reconstruct TracksReconstruct Tracks diagram

This tool works with a time-enabled layer of either point or polygon features that represent an instant in time. It first determines which features belong to a track using an identifier. Using the time at each location, the tracks are ordered sequentially and transformed into a line or polygon representing the path of movement over time. Optionally, the input may be buffered by a field, which will create a polygon at each location. These buffered points, or if the inputs are polygons, are then joined sequentially to create a track as a polygon where the width is representative of the attribute of interest. Resulting tracks have a start and end time, which represent temporally the first and last feature in a given track. When the tracks are created, statistics about the input features are calculated and assigned to the output track. The most basic statistic is the count of points within the area, but other statistics can be calculated as well.

Summarize AttributesSummarize Attributes diagram

Summarize Attributes takes an input layer and summarizes and calculate statistics on like values. The most basic statistic is the count of the number of features with a specified value, but you can get other statistics as well.

Summarize WithinSummarize Within diagram

The Summarize Within task finds features (and portions of features) that are within the boundaries of areas in the first input layer. The following are examples:

  • Given a layer of watershed boundaries and a layer of land-use boundaries, calculate the 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.

Tasks that find locations

TaskDescription
Detect IncidentsDetectIncidents diagram

The Detect Incidents task works with a time-enabled layer of points, lines, areas, or tables that represents an instant in time. Using sequentially ordered features, called tracks, this tool determines which features are incidents of interest. Incidents are determined by conditions that you specify. First, the tool determines which features belong to a track using one or more fields. Using the time at each feature, the tracks are ordered sequentially and the incident condition is applied. Features that meet the starting incident condition are marked as an incident. You can optionally apply an ending incident condition; when the end condition is true, the feature is no longer an incident. The results will be returned with the original features with new columns representing the incident name and indicate which feature meets the incident condition. You can return all original features, only the features that are incidents, or all of the features within tracks where at least one incident occurred.

Geocode Locations

Batch Geocode diagram

The Geocode Locations task geocodes a table from a big data file share. The task uses a geocode utility service configured with your portal. If you do not have a geocode utility service configured, talk to your administrator. Learn more about configuring a locator service.

Find Similar LocationsFind Similar Locations diagram

The Find Similar Locations task measures the similarity of candidate locations to one or more reference locations.

Tasks that analyze patterns

TaskDescription
Calculate DensityCalculate Density diagram

The Calculate Density task creates a density map from point features by spreading known quantities of some phenomenon (represented as attributes of the points) across the map. The result is a layer of areas classified from least dense to most dense.

Find Hot SpotsFind Hot Spots diagram

The Find Hot Spots task analyzes point data (such as crime incidents, traffic accidents, trees, and so on) or field values associated with points. It finds statistically significant spatial clusters of high incidents (hot spots) and low incidents (cold spots). Hot spots are locations with lots of points and cold spots are locations with very few points.

Create Space Time CubeCreate Space Time Cube diagram

Create Space Time Cube works with a layer of point features that are time enabled. It aggregates the data into a three-dimensional cube of space-time bins. When determining the point in a space-time bin relationship, statistics about all points in the space-time bins are calculated and assigned to the bins. The most basic statistic is the number of points within the bins, but you can calculate other statistics as well.

Note:

Create Space Time Cube is not available in the Enterprise portal's Map Viewer. Create Space Time Cube is available through ArcGIS Pro and the ArcGIS Server REST API.

Tasks that use proximity

TaskDescription
Create BuffersCreate Buffers diagram

Buffers are typically used to create areas that can be further analyzed using other tools. For example, if the question is What buildings are within 1 mile of the school?, the answer can be found by creating a 1-mile buffer around the school and overlaying the buffer with the layer containing building footprints. The end result is a layer of those buildings within 1 mile of the school.

Tasks that manage data

TaskDescription
Calculate Field

The Calculate Field task works with a layer to create and populate a new field or edit and existing field. The output is a new feature service, that is the same as the input features, with the newly calculated values.

Copy to Data StoreCopy to Data Store

Copy To Data Store takes an input layer and copies it to a data store. Data is copied to ArcGIS Data Store and is stored in your relational or spatiotemporal data store.
