Exploring the spatial relationship between features in the same or different datasets is possible with the Proximity Analysis tool.
Configured by a step-by-step wizard, the Proximity Analysis tool allows users to rapidly answer spatial questions such as:
- how many households are within 5 miles from a hospital?
- do any highways fall within 500m of a stream?
- how many property lots fall within a selected zoning area?
The proximity tool allows Administrators to customize results in a report using variables from the results table, and also choose how the results can be viewed and downloaded.
The Proximity Analysis tool lets you build powerful spatial queries to determine the relationship between selected points or features and neighboring points or features.
Configuration
To activate Proximity Analysis for your web map, open your toolbox and activate the tool.
Tool Name
Give your tool a custom name that is specific to the use case of your map.
Description
Give a custom description that gives the end user an explanation of the tool or brief instructions.
Measurement Units
Set the units displayed in the search.
Highlight Color
The color of the highlight that will be applied to selected features and features in the results.
Queriable Layers
Choose which layers will be used for the analysis. For each layer you enable, you can set the limitations or scope of the search on that layer. Open the Layer Settings to configure each layer.
You must activate every layer you wish to use in the query. For example. If you have a polygon layer and a point layer and wish to calculate the number of points that fall within the polygons, you must enable both layers in the Queriable layers.
Layer Query Settings
Layer Name indicates how the layer will be named in the tool. It’s best to use brief, descriptive names so that it is clear to users what data they are querying.
Filter Options To ensure a targeted search, you can filter and enable only relevant fields to be available to the search user for each layer.
Enable Filter by data fields, and select the fields you wish to be queriable. Unselected fields will not appear in the search filters, nor be shown in the search report.
Any attributes checked in the “Attributes in Filter” dropdown will be displayed as filter options to the end user for the selection or results set.
Results Options
The results output of the search allows you to tailor the results to the user’s needs. You can allow users to view results as a table, view a pre-configured report using the report builder, or download results in a spatial file.
Report Builder
The Report Builder allows you to configure meaningful summarized results that provide instant insights for users.
Custom Widget
Configure your own custom report using result, and custom equations with javascript syntax. For details on creating a custom report, please read this article.
Aggregate Table
Returns a table of values for the selected field.
