Network GIS Performance

Computing performance; Quality of services

Definition

Network geographic/geospatial information systems (GIS) performance (NGP) refers to the level of quality of services (QoS) of a network GIS. NGP includes both the efficient use of network-GIS resources (CPU, memory, massive storage, geospatial data and geospatial services) and the perception of speed of a network GIS [1]. Network GIS is a GIS where the geospatial data and geospatial processing are distributed across a computer network [2]. The performance [3] can be broken down into different factors, such as user‐perceived system response time, system reliability, system extensibility, and system service quota. Different practitioners with different roles for a network GIS have different views of NGP (Table 1).
