Split comparison is a widely used feature in geospatial analysis. As you might have understood from the name, this feature helps you compare two raster files in a split view. You need at least two date mosaics created in the current AOI to split compare. You will be given the option to choose the mosaic on the left and right-hand side of the split view. To make it more useful, Aurora provides you with an option to choose between visualization styles of raster on each side of the slider. Let’s try this out:

  1. Go to an AOI containing images from two different dates.
  2. Once you reach there, go to the Split Compare button on the right-hand side of the screen and click on it.
  3. You will find a list of already created visualizations, if no visualization is present, you need to create the visualization by clicking on the + Add Visualization button
  4. Select a visualization and you’ll see a raster with a slider along with the date select option below on each side of the slider.
  5. Select the dates you want to split and compare from the dates dropdown.
  6. After selecting the dates, you can change the visualization style of both sides of the slider in the visualization panel on each side.
  7. Now, you can use the slider to compare the changes in both dates
