  • JavaScript code editor
  • Map display for visualizing geospatial datasets
  • API reference documentation (Docs tab)
  • Git-based Script Manager (Scripts tab)
  • Cabinet turnout (Console tab)
  • Task Manager (Tasks tab) to handle long-lengthwise queries
  • Interactive map query (Inspector check)
  • Seek of the data archive or redeemed scripts
  • Geometry draught tools

The Code Editor has a sort of features to help you trespass of the Earth Engine API. View example scripts or save your own scripts on the Scripts tab. Query objects placed on the map with the Inspector tabloid. Expose and chart numeric results using the Google Visualization API. Parcel a unique URL to your script with collaborators and friends with the Get Link button. Scripts you explicate in the Code Editor are sent to Google for processing and the generated map tiles and/or messages are sent back for display in the Map and/surgery Console tab. All you ask to run the Code Editor is a web web browser (use Google Chromium-plate for best results) and an net connection. The following sections key out elements of the Earth Engine Encrypt Editor in more detail.

JavaScript editor

The JavaScript editor will:

  • Format and highlight code every bit you type
  • Underline code with problems, offer fixes and other hints for correct syntax
  • Autocomplete pairs of quotes, brackets and parentheses
  • Offer code completion hints for Earth Engine functions

In a higher place the code editor program are buttons for functional the script, saving the script, resetting the output map and console, and getting a relate to the script. When the Get Link button is pressed, a unique linkup will appear in the web browser's address ginmill. This link represents the code in the editor at the metre the button was pressed.

API source (Docs tab)

Happening the left side of the Code Editor is the Docs tab, which contains the complete JavaScript API documentation. The documentation can be searched and browsed from the Docs tab.

Script Director (Scripts tab)

The Scripts tab is close to the API Docs in the socialist panel of the Code Editor in chief. The Script Manager stores private, shared and example scripts in Git repositories hosted past Google. The repositories are set by access level, with your tete-a-tete scripts stored in a repository you have in the Owner pamphlet: users/username/default. You (and only you) throw entree to the repositories in the Owner folder unless you share them with somebody else. The repositories in the Writer folder are repositories for which write accession has been granted to you away their owner. You can add new scripts to, modify existing scripts in, or change access to (you may not take away their owner) the repositories in the Author folder. The repositories in the Reader pamphlet are repositories for which say access has been granted to you away their owner. The Examples folder is a special repository managed away Google which contains codification samples. The Archive folder contains legacy repositories to which you cause approach but have non yet been migrated by their owner from an older version of the Hand Manager. Look through with your scripts using the filter bar at the top of the Scripts tab.

scripts
Figure 2. The Script Coach.

Dawn the button to make a new repository in the Proprietor leaflet or to create folders and files within a deposit. You can rename scripts with the ikon and blue-pencil them with the picture. You can motility scripts and organize them into folders victimisation drag and sink (Figure 2). If you drag a script to another monument, information technology gets copied.

All scripts and repositories defend full version history. Click on the ikon next to a playscript or repository to compare Beaver State revert it to an older version. To delete a repository, click the picture. To configure approach to a repository, click the icon incoming to the repository name. Note that if you parcel a repository, the person with whom you'Re sharing volition need to accept the monument by clicking the link shown in the settings dialog. Previously accepted repositories can embody hidden aside clicking the icon following the repo name in the Playscript Manager.

Repositories can be accessed using Git, soh you can superintend and delete your scripts outside the Code Editor, or sync them with an external system like GitHub. (Learn more about Skunk from this teacher). Click on the icon next to the repository name for instructions on cloning the secretary. Note that you can browse the repositories to which you have access by expiration to earthengine.googlesource.com. For some Git operations, you may need to make over authentication credentials by going to the Generate Password connectedness at the superlative of the earthengine.googlesource.com page.

Playscript modules

It's good exercise to write modular, recyclable code that can be shared betwixt scripts without extensive copying and pasting. To enable modular development, Earth Engine provides the ability to share code between scripts. For example, speculate you write a function that performs a useful set of operations. Rather than copy the code of the function into a new script, it's easier for the new script to load the function directly. To make a function or object disposable to else scripts, you add information technology to a special object called exports. To use the code in some other script, use the require function to load the exports from some other script. For example, suppose you define the following faculty in a Indian file titled FooModule.js which is in a folder named Modules:

Code Editor in chief (JavaScript)

/**  * The Foo module is a demonstration of script modules.  * It contains a foo function that returns a greeting string up.  * It also contains a bar object representing the current escort.  * @module Modules/FooModule  */  /**  * Returns a greeting string.  * @param {ee.String} arg The name to which the salutation should be addressed  * @return {electrical engineering.String} The complete salutation.  */ exports.foo = function(arg) {   riposte 'Hello, ' + arg + '!  And a good day to you!'; };  /**  * An ee.Date stamp physical object containing the time at which the object was created.  */ exports.bar = EE.Date(Escort.now());

Observe the use of the exports keyword in the form of exports.objectToExport. You can make use of this mental faculty in some other script by using the require function. For example:

Code Editor (JavaScript)

var Foo = require('users/username/nonpayment:Modules/FooModule.js');  print(Foo.physician);  print(Foo.foo('earthly concern'));  print('Clock time now:', Foo.bar);

The require function expects a string that describes the absolute path to the location of the mental faculty. Specifically, the contention of require() is of the constitute 'pathToRepository:pathToModuleScript'. You can only load modules from repositories that you own and/or have scan admittance to. If you want others to embody able to use your faculty, the repository must be shared with the other users you want to have access. You may wish to papers your module to help others sympathize how to usage it; we recommend victimisation JSDoc style with the @module tag.

You can utilise the Universal resource locator parameter ?scriptPath={repo}:{book} to share a reference to a lodge in your repo, e.g. https://code.earthengine.google.com/?scriptPath=users/username/utils:utils. Upon visiting the URL, the referenced file and its repo will be added to either the Reviewer operating theatre Writer directory on the Scripts tab, depending connected your permission level for the shared repo.

Asset Director (Assets tab)

The Asset Manager is in the Assets tablet in the left panel. Use the Asset Manager (Figure 3) to upload and manage your own prototype assets in Earth Engine. See the Plus Manager page for details.

Code Editor scripts can be shared via an encoded URL. The succeeding sections line various ways to generate a script URL, available options, and methods for managing script URLs.

The "Get Link" button at the top of the Write in code Editor (Figure 4) provides an interface for generating script URLs and mount script behavior options. Note the distinctions between snapshot and redeemed script URLs described below.

link
Figure 4. The "Get Link" button.

Code in the Editor in chief can be shared via an encoded snapshot URL that gets created upon clicking the "Beat Data link" release at the top of the Code Editor in chief. When the Uniform resource locator is visited by someone with an Solid ground Engine account, the browser will pilot to the Code Editor and copy the environment equally it was when the colligate was created, including code, imports, map layers, and map out position. Clicking the "Get Link" clitoris wish automatically copy the script link to the clipboard. Additionally, a dialog box will appear providing options to control the execution of the shared handwriting, along with buttons to copy and visit the generated connexion. The control options include preventing the script from mechanically functional, and hiding the code pane when someone opens the shared inter-group communication. The draggable panel can be dismissed via the "Esc" key surgery a click elsewhere on the page.

Saved scripts have an selection to percentage a link that will always load the most Holocene epoch saved reading and is only accessible by you and others with live access to the repository containing the script. To use of goods and services this feature, load a saved script from the Script Director tab, dog the dropdown arrow to the right of the "Get Link" button and select "Copy Script Route". A dialog box will appear presenting the shareable script URL. Notice that the script URL has likewise been set in the browser's handle bar. For guidance on communion your repository with others, please see the Script Handler incision.

The dropdown button to the right of the "Get Link" clitoris has an option to "Manage Links". Clicking this option loads a new web browser tab with an user interface for you to recall, remove, and download previously generated script links. Selecting a handwriting and pressing the download button will download a zipped folder ("code_editor_links.zip") to your organisation containing a .txt file representation for each selected script.

The ui.url module allows programmatic manipulation of the script URL's fragment identifier via get and set methods. This means that Cipher Editor scripts and Earth Railway locomotive Apps can read and store values in the Sri Frederick Handley Page's URL. Notice the end of the following ii URLs, the first sets the debug covariant as false and the second sets information technology as true; impose both links and notice that the debug checkbox in the console is non checked in the first, and is checked in the irregular, changing the doings of each script.

https://code.earthengine.Google.com/5695887aad76979388a723a85339fbf2#debug=false;        
https://code.earthengine.google.com/5695887aad76979388a723a85339fbf2#debug=true;        

This feature give the sack be used to set correspondenc zoom and center, as well as new behaviors you might want to customize when sending links to particular proposition people or groups.

To find datasets to use in your scripts, you can use the search tool for the information archive. The search tool is the textbook box at the top of the Code Editor that says 'Hunt places and datasets...' Type the name of a data product, sensor, OR other keyword into the explore bar and tick the button to meet a list of matching places, raster and table datasets. Click on any raster or table ensue to see the description for that dataset in the archive. To spell the dataset directly into your script, click the import link or the button from the dataset description.

Imports

The results of importing datasets to your script are organized in an imports section at the upmost of your script, hidden until you import something. Once you have created some imports, you should envision something similar to Figure 5. To copy imports to other script, or convert the imports to JavaScript, click the ikon succeeding to the Imports header and copy the generated code into your script. You can delete the import with the icon.

Map out

The Map object in the API refers to the map reveal in the Encode Editor. For exemplar, Map.getBounds() will return the geographical region visible in the Code Editor in chief. Confirmation the Correspondenc functions in the API to see other customizations for this expose.

Layer Manager

Use the Level Manager in the upper right corner of the correspondenc to adjust the expose of layers you added to the map out. Specifically, you can on-off switch the visibility of a layer or adjust its transparency with the slider. Click the icon to adapt visual image parameters for individual layers. The visualization tool that appears (Figure 6) allows you to interactively configure layer exhibit parameters. Click the button on the right of the tool (which performs a Custom stretch to the supplied Amoy and max range by default) to linearly stretch the display to either percentiles or standard deviations of image values in the display windowpane. Statistics are computed from totally the pixels in the Map windowpane at the prevalent zoom level. Habit the sliders to adjust da Gamma and/or transparency. Mouse click the Palette wireless button and specify a tailored palette by adding colors (), removing colors () surgery manually entering a comma separated tilt of hex strings (). Click Give to apply the visualization parameters to the current exhibit. Click Import to load a visualization parameters physical object as a new variable in the imports section of your hand.

Note that to the right of the Layer Manager are toggle buttons for different map backgrounds. Customize the background using Correspondenc.setStyle().

Inspector tab

The Inspector tab next to the Task Manager lets you interactively query the map. When the Inspector tab is reactive, the pointer becomes a crosshair which will display the location and layer values under the pointer when you pawl on the map. For instance, Figure 7 shows the results of clicking on the map with in the Inspector tab. The cursor location and zoom level are displayed on with pixel values and a list of objects on the map. The objects number is mutual. To see more information, expand the objects in the Examiner yellow journalism.

Console Yellow journalism

When you print() something from your script, such atomic number 3 text, objects or charts, the result will Be displayed in the Console. The console is interactive, so you can flesh out printed objects to get more details about them.

Tasks tab

Earth Engine Tasks are operations that are capable of running game a great deal longer than the regular API request timeout. These drawn-out-running tasks are the only mechanism for creating persistent artifacts in Ground Engine and adjacent systems (Google Cloud Storage, Google Ram, etc.), and they fall into two categories: Import and Exportation.

Import tasks can be used to upload images or upload tables into Earth Railway locomotive from a variety of filetypes (.csv, .tif, etc.). Export tasks can be wont to execute and write results from the EE computation system of rules (see the guide for exporting data ).

For exports, each call to an Export affair in the Code Editor will populate an ledger entry in the Unsubmitted tasks segment of the Tasks tab. To submit an export task to the server, click the Track down button next to the task. A configuration dialog will appear that allows you to specify a variety of parameters for the task. If the project is full specified at creation time (that is, the call to Export has all necessary parameters), hold ctrl surgery while clicking Run to submit the project without showing the dialog.

For imports, file upload happens locally before the task is submitted to the server. Import tasks in the upload phase will show their build in the Unsubmitted tasks plane section and mechanically submit to the waiter once the file upload is complete.

Unsubmitted tasks only seem on the foliate which created them, and they are lost when the page is closed. Once a task is submitted to the server, clicking on its row in the UI will provide additional information and options about the task status, including the selection to request cancellation.

To view, search and cancel many tasks in a gas-filled-page view (including connected mobile clients), use the Task Manager.

Profiler

The profiler displays information about the resources (C.P.U. time, memory) used-up aside specific algorithms and other parts of a figuring. This helps to name why a book is pouring slowly Oregon failing due to memory limits. To use the profiler, click the Run with profiler option in the dropdown on the Scarper button. As a shortcut, hold down Alt (or Option along Mac) and chink Run, or press Ctrl+Alt+Enter. This activates a Profiler tab on the right side of the code editor. As the script runs, the Profiler check will video display a table of imagination utilisation from the script. Clicking the Run button (without profiling) will take the Profiler tab disappear and disable the profiler.

The profiler displays information about CPU and storage usage (per algorithm and asset) resulting from computations invoked aside the script and the display of every tile presently panoptic in the map. Each row in the profiler production corresponds to an algorithmic rule, computation, plus load or operating cost operation as described in the 'Description' column. The columns in the profiler are:

Description
A matter description of the computation, algorithm, asset load Oregon overhead operation beingness profiled.
Count
An index number progressive to the number of multiplication the performance delineated in 'Description' was invoked.
Reckon
An indicator of CPU time taken by the functioning(s).
Current Mem
This tower appears only if at that place was an error because the script used too some memory. It shows the amount of memory in manipulation on any single figure out node at the moment the error occurred.
Tiptop Mem
Maximum computer memory used on any man-to-man compute guest for the surgical operation.

You can also import geometries to your script by drawing them on screen. To create geometries, use the geometry drafting tools in the upper left turning point of the map out video display (Figure 8). For drawing points, use the placemark icon , for drawing lines, use the line icon , for drawing polygons, use the polygonal shape icon , for drawing rectangles use the rectangle icon . (Note that rectangles are planar geometries, so they cannot be placed on a layer with geodesic geometries same lines and polygons.)

Victimisation any of the drawing tools will automatically create a new geometry layer and add an signification for that layer to the Imports section. To ADD geometries to a new layer, hover on the Geometry Imports in the represent display and detent the +spic-and-span layer link. You lavatory besides toggle visibleness of the geometries from the Geometry Imports division. Note that worn geometries are geophysical science by default, except for rectangles, which are planar only. Practice the Geometry constructor to convert them to planar geometries. Learn more about geometries in Earth Engine on the Geometry varlet.

geometries
Figure 8. The geometry drafting tools are in the high left field corner of the map display.

To configure the direction geometries are strange to your script, pawl the icon next to the layer in the Geometry Imports section happening the map surgery in the Imports section of the code editor. The geometry layer settings tool will be displayed in a panel which should look something like Figure 9. Eminence that you give the axe import the drawn shapes American Samoa geometries, features or feature collections. The geometry import settings also countenance you to change the color with which the layer is displayed, add properties to the stratum (if it is imported as a Feature or FeatureCollection) or rename the bed.

geometry_import
Figure 9. The geometry shape puppet.

Finally, to prevent geometries in a bed from being emended, you prat lock the layer aside pressing the icon adjacent to the stratum. This wish preclude adding, deleting, or editing whatsoever geometries connected the bed. To unlock the layer again, printing press the icon.
