Measuring Geographic Distributions with GeoPandas: Standard Distance

Leave a Comment / GeoPandas, GIS /

Table of Contents Introduction The Standard Distance, also know as the Standard Distance Deviation, is the average distance all features vary from the Mean Center and measures the compactness of a distribution. The Standard Distance is a value representing the distance in units from the Mean Center and is usually plotted on a map as a circle for a visual indication of dispersion, the Standard Distance is […]

Leave a Comment / GeoPandas, GIS /

Table of Contents Introduction Also known as the Center of Minimum Distance, the Median Center is a location that is the shortest total distance to all features in the study area (not to be confused with the Central Feature, which is the feature that is the shortest distance to all others). It can be used to find a suitable

Measuring Geographic Distributions with GeoPandas: Central Feature

Leave a Comment / GeoPandas, GIS /

Table of Contents Introduction The Central Feature is the point that is the shortest distance to all other points in the dataset and thus identifies the most centrally located feature. The Central Feature can be used to find the most accessible feature, for example, the most accessible school to hold a training day for teachers from schools in a

Measuring Geographic Distributions with GeoPandas: Mean Center

Leave a Comment / GeoPandas, GIS /

Table of Contents Introduction The Mean Center is the average X coordinate and Y coordinate for all features in a study area and is the simplest descriptor of a geographic distribution. The Mean Center is generally used to track the changes in a features distribution over time and can also be used to compare the distribution of multiple features.
