This\ntutorial provides examples of how to use Earth Engine to analyze geospatial raster and\nvector data. By the end of the tutorial, you will have seen most of the basic\nfunctionality of the Earth Engine API.\n\nPrerequisites\n-------------\n\n- [Register for Earth Engine](https://console.cloud.google.com/earth-engine).\n- If you are unfamiliar with JavaScript, check out the [JavaScript for Earth Engine tutorial](/earth-engine/tutorials/tutorial_js_01) before proceeding.\n- Get familiar with the [Earth\n Engine Code Editor](https://code.earthengine.google.com), the IDE for writing Earth Engine JavaScript code in a web browser. Learn more about the Code Editor [here](/earth-engine/guides/playground).\n\nOnce you're familiar with JavaScript and the Code Editor, visit the next page to learn about\nvisualizing images and image bands. \n[Next pagearrow_forward](/earth-engine/tutorials/tutorial_api_02)"]]
