ee.ErrorMargin
Stay organized with collections
Save and categorize content based on your preferences.
Returns an ErrorMargin of the given type with the given value.
| Usage | Returns | ee.ErrorMargin(value, unit) | ErrorMargin |
| Argument | Type | Details | value | Float, default: null | The maximum error value allowed by the margin. Ignored if the unit is 'infinite'. |
unit | String, default: "meters" | The unit of this margin: 'meters', 'projected' or 'infinite'. |
Examples
Code Editor (JavaScript)
// Construct a variety of error margins.
print(ee.ErrorMargin(0)); // unit: meters value: 0
print(ee.ErrorMargin(1)); // unit: meters value: 1
// Negative margin yields a positive value.
print(ee.ErrorMargin(-1)); // unit: meters value: 1
// Large values are turned into an 'infinite'
print(ee.ErrorMargin(1e8)); // unit: infinite
// A very large error margin does not quite trigger infinite, which is 2.0e7.
print(ee.ErrorMargin(1e7)); // unit: meters value: 10000000
// Being explicit about the units of the error margin.
print(ee.ErrorMargin(1, 'meters')); // unit: meters value: 1
print(ee.ErrorMargin(1, 'projected')); // unit: projected value: 1
print(ee.ErrorMargin(1, 'infinite')); // unit: infinite
