What is GeoServer?
GeoServer is an open-source server application that allows users to share and publish geospatial data and maps over the internet. It is written in Java and supports the Open Geospatial Consortium (OGC) standards, making it compatible with a wide range of geospatial data formats and services.
GeoServer acts as a web server for geospatial data, providing a platform for storing, processing, and distributing maps and spatial data. It allows users to publish their geospatial data as web services using standard protocols like Web Map Service (WMS), Web Feature Service (WFS), and Web Coverage Service (WCS). These services enable clients, such as GIS software, web applications, and mobile devices, to access and interact with the published data.
With GeoServer, users can create and manage data layers, define styling and symbology, perform geospatial analysis, and configure advanced data serving options. It is widely used in various domains, including government, environmental management, urban planning, agriculture, and natural resource management.
GeoServer is highly extensible and customizable, with a large community of developers contributing to its ongoing development and support. It provides a user-friendly web interface and offers powerful features for geospatial data sharing and dissemination.
