The JavaScript editor will: 1. Format and highlight code as you type 2. Underline code with problems, offer fixes and other hints for correct syntax 3. Autocomplete pairs of quotes, brackets and parentheses 4. Offer code completion hints for Earth Engine functions Above the code editor are buttons for running the script, saving the script,resetting...
On the left side of the Code Editor is the Docs tab, which contains thecomplete JavaScript API documentation. The documentation can be searched andbrowsed from the Docstab.
The Scripts tab is next to the API Docs in the left panel of the CodeEditor. The Script Manager stores private, shared and example scripts inGit repositories hosted by Google. The repositories arearranged by access level, with your private scripts stored in a repository youown in the Owner folder: users/username/default. You (and only you) haveacce...
It's good practice to write modular, reusable code that can be shared betweenscripts without extensive copying and pasting. To enable modular development,Earth Engine provides the ability to share code between scripts. For example,suppose you write a function that performs a usefulset of operations. Rather than copy the code of the function into a ...
The Asset Manager is in the Assets tab in the left panel. Use the AssetManager (Figure 3) to upload and manage your own image assets in Earth Engine.See the Asset Manager pagefor details. Figure 3. The Asset Manager.
Code Editor scripts can be shared via an encoded URL. The following sectionsdescribe various ways to generate a script URL, available options, and methodsfor managing script URLs.
To find datasets to use in your scripts, you can use the search tool for thedata archive. The search tool is the text box at the top of the Code Editor thatsays 'Search places and datasets...' Type the name of a data product, sensor, orother keyword into the search bar and click the searchbutton to see a list of matching places, raster and table da...
The results of importing datasets to your script are organized in an importssection at the top of your script, hidden until you import something. Once youhave created some imports, you should see something similar to Figure 5. To copyimports to another script, or convert the imports to JavaScript, click thesubject icon next to the Imports header an...
The Map object in the API refers to the map display in the Code Editor. Forexample, Map.getBounds() will return the geographic region visible in the CodeEditor. Check the Mapfunctions in the API to see other customizations forthis display.
Use the Layer Manager in the upper right corner of the map to adjust the displayof layers you added to the map. Specifically, you can toggle the visibility of alayer or adjust its transparency with the slider. Click thesettingsicon to adjust visualization parameters for individual layers. The visualizationtool that appears (Figure 6) allows you to ...
