Parcels

Accela GIS provides a set of API's that query an agency's GIS parcel data source and returns parcel information using a standard parcel data model used across Accela Civic Platform solutions.

Which Search Parcels endpoint to use

Use the Search Parcels endpoint that is specific to the type of query object criteria.

The Accela GIS API provides separate Search Parcels resource endpoints for each type of query object. Although they all return the same parcel resource object model, the separate endpoints are provided for efficiency and performance purposes. If an application wishes to query parcels that are associated with a specific address, it is more efficient to use Search Parcels by Address instead of Search Parcels by Multiple with an address query object. Similarly, to search parcels based on parcel fields, use Search Parcels by Parcel; to search parcels associated with a specific owner, use Search Parcels by Owner. Search Parcels by Multiple performs combinations of spatial queries per address, parcel, and owner object attribute specified in the request body and can execute longer than the other type-specific resource endpoints.

Configuration

  • The Search Parcels API's require that the XAPO data source fields are mapped to Civic Platform APO fields. The XAPO field mapping is defined on the GIS Admin Site > {agency} > XAPO Configuration page.

  • A GIS agency administrator can set the XAPO configuration setting Feature Count Limit which defines the maximum number of returned results. The feature count limit is defined on the GIS Admin Site > {agency} > XAPO Configuration page. The default is 200. If the search results are greater than the feature count limit, the API returns an error indicating the exceeded feature count limit; in this case, the API caller should re-submit the query with a narrower criteria or set the maxRows page setting to a number less than the feature count limit.
