Understanding Workflow Automation Defining workflows and geoprocessing in GIS A geographic information system (GIS) workflow is a sequence of geoprocessing tools and models that automate spatial analysis and data management tasks. Geoprocessing refers to the manipulation and analysis of geographic data to create new output datasets. Manual geoprocessing using the GIS graphical user interface is…
Understanding GPS Accuracy The Global Positioning System (GPS) provides location and time information around the world. However, the accuracy of GPS measurements can vary considerably depending on factors like satellite geometry, signal blockage, atmospheric conditions, and receiver quality. Defining the accuracy metrics for GPS involves specifying quantitative measures like positional dilution of precision (PDOP) and…
Understanding Spatial Clustering Spatial clustering refers to the process of grouping together geographic data points that are close to each other to reveal patterns. It is an important concept in geographic information systems (GIS) analysis that enables the identification of hot spots, trends, and distributions that would not be visually apparent without using clustering techniques….
