These are stored in PySAL shape objects, which can be used by PySAL and can be converted to other Python shape objects. They typically have a few methods.
      • The quantile of a value is the fraction of observations or population less than or equal to the value. With quantile statistics we are very highly confident that the median value is not greater than zero.
      • The primary purpose of 3D Tiles is to improve streaming and rendering performance of massive heterogeneous datasets. The foundation of 3D Tiles is a spatial data structure that enables Hierarchical Level of Detail (HLOD) so only visible tiles are streamed - and only those tiles which are most important for a given 3D view.

    • 2012 election data. We use choropleth maps most of the time, but as we have mentioned in the preceding section, It has its limitations. Let us first make a choropleth map out of the data to create a benchmark for the data visualization.
      • The Quantiles scheme is one map classification method that GeoPanda includes, which are in turn based on PySAL. This has improved the visualization, but there are still questions. For example, how many different colors (hues) do we see?

      • Similar to the global case, there are more local indicators of spatial correlation than the local Moran’s I. PySAL includes Getis and Ord’s \(G_i\) and \(G_i^*\), which differ only on whether to exclude the self-value in the calculation or not, respectively. The way to calculate them also follows similar patterns as with the LISA above.
      • This generator uses the python-sld and pysal libraries to generate classes for map classification, and returns a StyledLayerDescriptor class object. This class object may be serialized to an SLD XML file, which is useful for many GIS and mapping software packages.
