Images with a bounding box, location or geometry using theĮe.Filter.bounds(). Filter by location: You can select the subset of.Particular date range using filters such as Filter by date: You can select images in a.Image metadata using filters such as ee.Filter.eq(),Įe.Filter.lt() etc. Filter by metadata: You can apply a filter on the.We will learn about 3 main types of filtering techniques Select aįilter and then run the filter() function with the filter There are many types of filter functions, look atĮe.Filter. We use filters to select theĪppropriate images. TheĮntire collections are not very useful. The collection contains all imagery ever collected by the sensor. The X and Y coordinates with the coordinates of your city and click (longitude), Y coordinate (latitude) and Zoom Level parameters. Map.setCenter() which sets the viewport to a specific In the code snippet, You will see a function Click Run and you will see the image tiles load in Click theĬopy Code Sample button and paste the code into theĬode editor. Is a great starting point for your work with this dataset. Level 1C page and see Explore in Earth Engine section toįind the code snippet to load and visualize the collection. Sentinel-2 Level 1C dataset and you will find its id You can load a collection by searching the Earth Engineĭata Catalog for the ImageCollection ID. The length of a path drawn around the ring road of MRU is 1.55 km (see yellow path on image).Most datasets in Earth Engine come as a ImageCollection.Īn ImageCollection is a dataset that consists of images takes atĭifferent time and locations - usually from the same satellite or data Figure T5: Using the ruler tool to measure the length of a path, rather than a simple straight line. Click clear to erase the line or path you measured. Notice that you can change the unit of measurement by using the drop down menu. Figure T5 shows a measured path along the ring road around MRU. You can also measure the length of a path, rather than just a straight line. This example shows that the length of two soccer fields at MRU is 151.47 m (see yellow line on map). The dialogue box will tell you the length of the line you are measuring. Figure T4: Using the ruler tool to measure distances in Google Earth. What distance did you measure? In Figure T4, the length of the line measured represents a real distance of 151.47 m. Click once to start measuring and click again to stop. Let’s use a line to measure the length of the two soccer fields at MRU. A dialogue box should pop up (see Figure T4). In Figure T1 below, the entire length of the scale bar represents a real distance of 230 m, and each division along the scale bar represents a real distance of 57.5 m.Ĭlick on the ruler icon in the toolbar located at the top of the screen. A scale bar helps you determine the actual, on the ground, distance between points or along lines. The bar in the bottom left corner of the image shows the scale bar (inside the orange box in Figure T1).In Figure T1, north is toward the top of the image (in the direction of the blue arrow). In the top right corner, the compass shows which direction is north in the current view.The red place marker shows the name and the exact location of the place you typed into the search bar.Let’s point out a few things you should know about Google Earth. From what altitude are you looking down on MRU? Figure T1: Annotated Google Earth map view of Mount Royal University (MRU), highlighting where to find the location marker for MRU (red box), the scale bar (yellow box), and north (blue arrow and compass in upper right corner).
