ee.Algorithms.ObjectType

  • ee.Algorithms.ObjectType() returns a string that represents the type of a given Earth Engine object.

  • It accepts a single argument, the object whose type you want to determine.

  • This function can be applied to primitive types (like numbers and strings), Earth Engine objects (like ee.Number and ee.String), and even properties within ee.Feature or ee.Image objects.

  • Examples demonstrate how to use this function in JavaScript and Python to obtain the object types.

 Returns a string representing the type of the given object.

UsageReturns
ee.Algorithms.ObjectType(value)String
ArgumentTypeDetails
valueObject, default: nullThe object to get the type of.

Examples

Code Editor (JavaScript)

print(ee.Algorithms.ObjectType(1));  // The string "Integer"
print(ee.Algorithms.ObjectType(ee.Number(1)));  // The string "Integer"
print(ee.Algorithms.ObjectType(ee.String('a string')));  // The string "String"
print(ee.Algorithms.ObjectType(ee.List([1, 'a string'])));  // The string "List"

// ee.Algorithms.ObjectType can be used to get the type of properties
// of ee.Image or ee.Feature objects.
var feature = ee.Feature(
  null,  // No need for geometry in this example.
  {
    'int': 42,
    'int8': ee.Number(-3).int8(),
  });

// The string "Integer"
print('int:', ee.Algorithms.ObjectType(feature.get('int')));
// The string "Long"
print('int8:', ee.Algorithms.ObjectType(feature.get('int8')));

Python setup

See the Python Environment page for information on the Python API and using geemap for interactive development.

import ee
import geemap.core as geemap

Colab (Python)

print(ee.Algorithms.ObjectType(ee.Number(1)).getInfo())  # The string "Integer"
print(
    ee.Algorithms.ObjectType(ee.String('a string')).getInfo()
)  # The string "String"
print(
    ee.Algorithms.ObjectType(ee.List([1, 'a string'])).getInfo()
)  # The string "List"

# ee.Algorithms.ObjectType can be used to get the type of properties
# of ee.Image or ee.Feature objects.
feature = ee.Feature(
    None,  # No need for geometry in this example.
    {
        'int': 42,
        'int8': ee.Number(-3).int8(),
    }
)

# The string "Integer"
print('int:', ee.Algorithms.ObjectType(feature.get('int')).getInfo())
# The string "Long"
print('int8:', ee.Algorithms.ObjectType(feature.get('int8')).getInfo())
