Geospatial

Walkthroughs of common operations on geospatial data.

📄️ Buffer Analysis

Buffer analysis is a geospatial technique used to extract meaningful insights from location-based data. It helps determine which objects fall within a certain distance of Areas of Interest (AOIs) and account for possible inaccuracies in GPS data. This technique has various applications such as visit attribution and proximity analysis.

📄️ Point in polygon

Point in polygon operations ask whether a given set of points in a map falls within a polygon. This technique is commonly used to enrich data from one dataset with information from another.

📄️ Raster to H3

Transforming raster data into H3 cells

📄️ Zonal Stats

Zonal statistics calculates aggregate statistics (e.g., mean, sum, maximum) of the pixel values of a raster that fall within areas defined by a Polygon dataset. The method has diverse applications such as determining vegetation health in an agricultural field, assessing surface water availability, or approximating building heights from DSM rasters.
