Esri Map Areas

This package contains a Lightning component that draws polygons read from a Salesforce related list onto an Esri map embedded in a record page. The component allows the user to choose between street, topological, and satellite views of the map.

EsriMapAreas in Action

Configuration

The component pulls coordinates from records in a related list. The related list object can be any Salesforce object, but must contain the following custom fields:

Field API Name Description
Item_Color__c The color of the polygon to be drawn using standard HTML/CSS format. For example, red or #f48723.
Coordinates__c A comma-separated list of two-member latitude/longitude arrays in JSON format that represent the polygon to be drawn on the map: [lat-1,lon-1],[lat-2,lon-2],...[lat-n,lon-n]
Formatted_Tab_URL__c A string that should evaluate to a URL path name (without the "https" or server portion, for portability) that will take the user to this record's page. I use a formula field to generate this based on the object API name and ID field: "/lightning/r/Property__c/" & Id & "/view"

The package includes a sample object called Property__c which contains all of the required fields. You can either use it as a reference or as a starting point for your own custom object (or even delete it altogether; it is not required by any other part of the package):

Sample Related List Object

From here, you can simply drag the component onto a Lightning App Builder page:

Most of the properties of the component default to reasonable values, but you must supply these two:

  • The API name of the related list object that contains the required fields described above.
  • The API name of the lookup field on the related list object that looks up to this object.

You may also specify up to nine additional fields to be displayed on the related list from the related list object. The strings in the component properties must be a "|"-separated sequence consisting of

  • (Required) The column header for the field you would like to show.
  • (Required) The API name of the field on the related object for that column.
  • (Required) A type string that identifies a type property of the Lightning datatable specification; for example, number, text, date, etc.
  • An optional JSON string that contains cellAttributes for the column in a form consistent with the Lightning datatable specification.
  • An optional JSON string that contains typeAttributes for the column in a form consistent with the Lightning datatable specification.

For example, the string for the purchase date column for the properties example above is:

Date Purchased|Date_Purchased__c|date|"alignment":"center"|"day":"numeric","month":"long","year":"numeric"

and the string for the acreage column is:

Acreage|Acreage__c|number|"alignment":"center"||

You can optionally sort the related list based on any field in the related list object in either ascending or descending order.
