Temporal Landsat 8 Collection: Resolving the Error in Image Multiplication

The Google Earth Engine (GEE) is a powerful platform for analyzing and processing large-scale geospatial data. One of its key features is the ability to create temporal collections, which allow users to analyze and visualize data over time. However, when working with temporal collections, users may encounter errors related to image multiplication. In this article, we will discuss the error "map(ID=0) Image.multiply: If one image has no bands, the other must also have no bands. Got 0 and 1" when using the Landsat 8 C2L2T1 temporal collection in GEE.

The error "map(ID=0) Image.multiply: If one image has no bands, the other must also have no bands. Got 0 and 1" occurs when trying to multiply two images in a temporal collection. This error is caused by the fact that one of the images in the collection has no bands, while the other image has one or more bands. In GEE, images with no bands are represented by a value of 0, while images with one or more bands are represented by a value of 1.

Landsat 8 C2L2T1 Temporal Collection

The Landsat 8 C2L2T1 temporal collection is a collection of Landsat 8 images that have been processed to Level 2 (L2) and are available in the Google Earth Engine. This collection includes images from 2013 to the present and is updated regularly. The collection is useful for analyzing and visualizing land surface temperature (LST) over time.

Error in Image Multiplication

When trying to multiply two images in the Landsat 8 C2L2T1 temporal collection, the error "map(ID=0) Image.multiply: If one image has no bands, the other must also have no bands. Got 0 and 1" occurs. This error is caused by the fact that one of the images in the collection has no bands, while the other image has one or more bands.

To resolve the error, you need to ensure that both images in the collection have the same number of bands. You can do this by:

Filtering the collection: Filter the collection to only include images with the same number of bands. You can use the filter function in GEE to filter the collection based on the number of bands.
Merging the collection: Merge the collection to create a new collection with the same number of bands. You can use the merge function in GEE to merge the collection.
Using a different collection: Use a different collection that has the same number of bands. You can use the select function in GEE to select a different collection.

Here is an example code that demonstrates how to resolve the error:

// Define the Landsat 8 C2L2T1 temporal collection
var collection = ee.ImageCollection('LANDSAT/LC08/C01/T1_L2')
  .filterDate('2013-01-01', '2014-01-01')
  .filterBounds(ee.Geometry.Point(-122.08, 37.38));
// Filter the collection to only include images with 6 bands
var filteredCollection = collection.filter(ee.Filter.eq('BANDS', 6));
// Merge the collection to create a new collection with 6 bands
var mergedCollection = filteredCollection.merge(collection.filter(ee.Filter.eq('BANDS', 6)));
// Multiply the images in the merged collection
var result = mergedCollection.map(function(image) {
return image.multiply(image);
});

In conclusion, the error "map(ID=0) Image.multiply: If one image has no bands, the other must also have no bands. Got 0 and 1" occurs when trying to multiply two images in the Landsat 8 C2L2T1 temporal collection. This error is caused by the fact that one of the images in the collection has no bands, while the other image has one or more bands. To resolve the error, you need to ensure that both images in the collection have the same number of bands. You can do this by filtering the collection, merging the collection, or using a different collection.

Use the select function: Use the select function to select a different collection that has the same number of bands.
Use the filter function: Use the filter function to filter the collection to only include images with the same number of bands.
Use the merge function: Use the merge function to merge the collection to create a new collection with the same number of bands.
Use a different collection: Use a different collection that has the same number of bands.

Error in image multiplication: The error "map(ID=0) Image.multiply: If one image has no bands, the other must also have no bands. Got 0 and 1" occurs when trying to multiply two images in the Landsat 8 C2L2T1 temporal collection.
Missing bands: One of the images in the collection has no bands, while the other image has one or more bands.
Inconsistent collection: The collection is inconsistent, and the images have different numbers of bands.

Check the collection: Check the collection to ensure that it is consistent and has the same number of bands.
Check the images: Check the images in the collection to ensure that they have the same number of bands.
Use the select function: Use the select function to select a different collection that has the same number of bands.
Use the filter function: Use the filter function to filter the collection to only include images with the same number of bands.
Use the merge function: Use the merge function to merge the collection to create a new collection with the same number of bands.
Frequently Asked Questions (FAQs) about Temporal Landsat 8 Collection: Resolving the Error in Image Multiplication

A: The Landsat 8 C2L2T1 temporal collection is a collection of Landsat 8 images that have been processed to Level 2 (L2) and are available in the Google Earth Engine. This collection includes images from 2013 to the present and is updated regularly.

A: The error "map(ID=0) Image.multiply: If one image has no bands, the other must also have no bands. Got 0 and 1" occurs when trying to multiply two images in the Landsat 8 C2L2T1 temporal collection. This error is caused by the fact that one of the images in the collection has no bands, while the other image has one or more bands.

A: To resolve the error, you need to ensure that both images in the collection have the same number of bands. You can do this by:

Filtering the collection: Filter the collection to only include images with the same number of bands.
Merging the collection: Merge the collection to create a new collection with the same number of bands.
Using a different collection: Use a different collection that has the same number of bands.

A: Filtering a collection involves selecting a subset of images from the collection based on certain criteria, such as the number of bands. Merging a collection involves combining multiple collections into a single collection.

A: You can use the select function to select a different collection by specifying the collection name and the bands you want to select. For example:

var collection = ee.ImageCollection('LANDSAT/LC08/C01/T1_L2')
  .select(['B1', 'B2', 'B3', 'B4', 'B5', 'B6', 'B7']);

A: You can use the filter function to filter the collection by specifying the criteria you want to use. For example:

var collection = ee.ImageCollection('LANDSAT/LC08/C01/T1_L2')
  .filter(ee.Filter.eq('BANDS', 6));

A: You can use the merge function to merge the collection by specifying the collections you want to merge. For example:

var collection1 = ee.ImageCollection('LANDSAT/LC08/C01/T1_L2')
  .filter(ee.Filter.eq('BANDS', 6));
var collection2 = ee.ImageCollection('LANDSAT/LC08/C01/T1_L2')
  .filter(ee.Filter.eq('BANDS', 6));
var mergedCollection = collection1.merge(collection2);

A: Some common issues that can cause the error in image multiplication include:
