Cartegraph has the ability to use an Esri locator service. This allows organizations to use a custom geolocation service specific to their community, ensuring a higher level of accuracy with geocode and reverse geocode operations.
The areas of the system using the geolocation functionality are:
- Address Search: In all cases a user performs an address search in Cartegraph, a geocode event is initiated and the appropriate geolocation service is called. World Geocode service from ArcGIS Online as the default or an Alternate Esri Locator service if Cartegraph configured to do so.
- Create a point Asset or Request: In those cases where a user is creating a point asset or request location, the location of the Asset or Request (pin position) will initiate a reverse geocode event to obtain the address of that location.
When using an alternative Esri locator, the city may be required in the Address Search in order to find the entered address.
Click here for the steps to set up the Esri Locator.
The URL, Reverse Geocode Distance, Address Search Tooltip, and locator format fields are part of the locator setup. The candidate fields and examples may vary depending on the type and version of your locator.
Esri Locator Candidate Fields
Esri geocode services present candidate fields that requests for geolocations can be made against.
These candidate fields vary by the locator template used, but the following are a list of typically used candidate fields:
The REST Service URL for the organization. The URL typically follow this format:
https://<arcgis server address>/arcgis/rest/services/<locator service name>/Geocode Server/
Reverse Geocode Distance
This value determines how far from a pin location the service looks to find a street segment with an address. This value is measured on the map in meters, and should be entered in meters.
Address Search Tooltip
When a user searches for an address in Cartegraph, and if the address is found, the map pans and zooms to that address location. A pin is dropped on the map reflecting that address location and a map tool tip displays with the address, per the location service, of that pin location. These settings allow you to define what address items display in these map tips, and in what format and order. The user must populate these fields using the locator’s Candidate fields. which are returned from the Location service and display in the bottom part of the Geocode Settings screen.
For example, if a user-defined the following Address Search Tooltip with these candidate fields:
- Address Search Tooltip, Line 1 Format: AddNum StPreDir StName StType
- Address Search Tooltip, Line 2 Format: City, State
The results are:
3600 N. Digital Dr.
Locator Format Fields
These fields control two things:
- What Locator’s Candidate fields are used to populate their corresponding locator fields on a record in Cartegraph.
- How the map tooltip displays on reverse geocode events. For example, during the create process for assets and requests.
The same mapping process as used for the Tooltip definition fields should be followed here as well, filling in the appropriate candidate fields
A typical example: If a user-defined the following Locator fields with these candidate fields:
- Locator Address Number Format: AddNum
- Locator Street Format: StPreDir StName StType
- Locator City Format: City
The results would be:
Locator Address Number: 3600
Locator Street: Digital Dr.
Locator City: Dubuque
Select the appropriate secured GIS server from the Security Server list, only if the Esri Geocode web service/server is secured; or else leave it blank. You can set up the Esri Geocode Server in Manager Servers used for GIS Integrations, where the Geocode service was published. When setting up for a secured Esri geocode server in Manager Server, select either ArcGIS for Server credentials, ArcGIS Online credentials, or Portal credentials.
