Spatial Data Create/Update API

Spatial values retrieved from the database are formatted per the GeoJSON specification.

POINT Values

Consider the following table schema in Backendless database. Notice the pickupLocation and the dropoffLocation columns. Both are of type POINT:

The following code demonstrates how to create a new object with POINT properties in the Order table:

Notice the formatting of the dropoffLocation and the pickupLocation properties - they follow the structure of the Point GeoJSON  geometry.

Request method:

POST

Request header:

Content-Type:application/json

Request body:

{  
  "orderName": "Fun times",  
  "dropoffLocation": {  
    "type": "Point",  
    "coordinates": [ 37.6189, 55.752917 ]  
  },  
  "pickupLocation": {  
    "type": "Point",  
    "coordinates": [ 37.578639, 55.782309 ]  
  }  
}

Make sure to replace xxxx in the domain name in the sample request below to the one assigned to your application.

curl \

When you run the code, you will see the following in the database:

LINESTRING Values

Creating objects with LINESTRING properties works similarly to the example shown above - request must use the GeoJSON format to describe a linestring value. For example, the code below creates an object in the Travel table with a LINESTRING route:

Notice the formatting of the route property - it follows the structure of the LineString GeoJSON  geometry.

Request method:

POST

Request header:

Content-Type:application/json

Request body:

  "route": {

When you run the code, you will see the following object in the database:

POLYGON Values

Creating objects with properties of type POLYGON can be done by using the corresponding GeoJSON format. Consider the following example, it is a data table called Building with a schema which includes a column named shape of type POLYGON:

The code below demonstrates how to create a new object with a POLYGON property in the database:

Notice the formatting of the shape property - it follows the structure of the Polygon GeoJSON

Request method:

POST

Request header:

Content-Type:application/json
