Happy #MapInfoMonday.Today, we will play a bit with raster in MapInfo Pro again.Sometimes you need to understand the coverage area for specific values in your raster, or an overview of how much of a place is covered by what value from your raster. For a raster with floating point data, it's hard to do as very few values will be the same. They will vary slightly but enough to not be the same. For classified raster grids, it's much easier. The Raster Statistics panel gives you an overview of the coverage per class.Luckily, you can easily classify a floating point raster grid by specifying buckets of values that you want to group. Let me show you.I'll be using a digital elevation model in this example. Often the data you are using here would be values you have measured and not just an elevation grid. That could be noise, air pollution, rainfall, temperature, or data captured from a wireless network. The process is the same no matter what the source of your data is.
Sometimes I take things for granted. I forgot that not all raster formats are as versatile as our MRR.The Multi-Resolution Raster, MRR, format is actually one of the few raster formats that support various types of data, such as imagery, continuous, and classified.Read more about the Multi-Resolution Raster format in this support article: Multi Resolution Raster (MRR) - Revolutionizing Raster Performance and usage
