Use our web-based code editor for fast, interactive algorithm development with instant access to petabytes of data. Scientists and non-profits use Earth Engine for remote sensing research, predicting disease outbreaks, natural resource management, and more. Earth Engine for commercial use: now in preview with Google Cloud.
Code Editor scripts can be shared via an encoded URL. The following sections describe various ways to generate a script URL, available options, and methods for managing script URLs. Note the distinctions between snapshot and saved script URLs described below. When the URL is visited by someone with an Earth Engine account, the browser will navigate to the Code Editor and replicate the environment as it was when the link was created, including code, imports, map layers, and map position.
Additionally, a dialog box will appear providing options to control the execution of the shared script, along with buttons to copy and visit the generated link. The control options include preventing the script from automatically running, and hiding the code pane when someone opens the shared link. Saved scripts have an option to share a link that will always load the most recent saved version and is only accessible by you and others with current access to the repository containing the script.
A dialog box will appear presenting the shareable script URL. For guidance on sharing your repository with others, please see the Script Manager section.
Clicking this option loads a new browser tab with an interface for you to recall, remove, and download previously generated script links. The ui. Notice the end of the following two URLs, the first sets the debug variable as false and the second sets it as true ; visit both links and notice that the debug checkbox in the console is not checked in the first, and is checked in the second, changing the behavior of each script.
This feature can be used to set map zoom and center, as well as other behaviors you might want to customize when sending links to particular people or groups. To find datasets to use in your scripts, you can use the search tool for the data archive.
The search tool is the text box at the top of the Code Editor that says 'Search places and datasets Click on any raster or table result to see the description for that dataset in the archive. To import the dataset directly into your script, click the import link or the button from the dataset description.
The results of importing datasets to your script are organized in an imports section at the top of your script, hidden until you import something. Once you have created some imports, you should see something similar to Figure 5. To copy imports to another script, or convert the imports to JavaScript, click the subject icon next to the Imports header and copy the generated code into your script.
You can delete the import with the delete icon. For example, Map. Check the Map functions in the API to see other customizations for this display. Use the Layer Manager in the upper right corner of the map to adjust the display of layers you added to the map.
Specifically, you can toggle the visibility of a layer or adjust its transparency with the slider. Click the settings icon to adjust visualization parameters for individual layers. The visualization tool that appears Figure 6 allows you to interactively configure layer display parameters. Click the button on the right of the tool which performs a Custom stretch to the supplied min and max range by default to linearly stretch the display to either percentiles or standard deviations of image values in the display window.
Statistics are computed from all the pixels in the Map window at the current zoom level. Click the Palette radio button and specify a custom palette by adding colors add , removing colors remove or manually entering a comma separated list of hex strings edit. Click Apply to apply the visualization parameters to the current display.
Click Import to load a visualization parameters object as a new variable in the imports section of your script. Note that to the right of the Layer Manager are toggle buttons for different map backgrounds.
Customize the background using Map. The Inspector tab next to the Task Manager lets you interactively query the map. When the Inspector tab is activated, the cursor becomes a crosshair which will display the location and layer values under the cursor when you click on the map. For example, Figure 7 shows the results of clicking on the map with in the Inspector tab.
The cursor location and zoom level are displayed along with pixel values and a list of objects on the map.
