![]() You will need it to be able to use your shapefile extent to search for data. If you don’t have a login already, create an account.īe sure to create an account. ![]() Next, go to the Earth Explorer website.Lucky for us there is a zip file already zipped up and ready to go in your week 8 data! data/week-08/vector_layers/fire_boundary_box_shp.zip Be sure to use a square extent, if you have too many vertices it won’t work. Zip up extent file that you want to use.If you have too many vertices in your extent polygon, the website won’t accept it as an extent file. Important: Be sure to use a square / rectangular extent polygon. In the case of vector data - this represents the minimum and maximum x and y values for each corner boundary of the dataset. Remember that the spatial extent of a spatial object, is the geographic area that your data cover on the ground. You could type in the x,y vertices of each corner of the boundary, but if you have an Earth Explorer account, you can upload a ZIPPED up shapefile that contains the boundary instead. ![]() Your AOI for this week, is defined by the boundary of the Cold Springs fire extent. When searching for data, the first thing that you need to do is to define your area of interest (AOI). How to Download Landsat Remote Sensing Data from Earth Explorer Step 1: Define Your Study Area (AOI) IMPORTANT: Be sure to order your data several days ahead of time or else you won’t have it in time to finish your homework. Here you can find many different types of remote sensing and other data for both the US and in some cases, the globe. The Earth Explorer website is a data portal run by the USGS. In class this week, you will review how to grab data from the Earth Explorer website. You will need a computer with internet access to complete this lesson and the data for week 8 of the course. Filter data by cloud cover to find datasets with the least amount of clouds for a study area.Find and download data from the USGS Earth Explorer Website.After completing this tutorial, you will be able to: ![]()
