ONGis

ONGis refers to a proprietary enterprise geographic information system developed by ESRI. It is designed for large organizations and governments to manage and analyze spatial data. The "ON" in ONGis stands for "On-site" or "On-premise," indicating that it is typically installed and run on an organization's own servers, rather than being a cloud-based solution. This contrasts with newer ESRI offerings that are primarily cloud-native.

ONGis provides a comprehensive suite of tools for data creation, editing, management, and visualization. It allows users to integrate various types of geographic data, perform complex spatial analysis, and create maps and reports. The system is known for its scalability and its ability to handle large volumes of data, making it suitable for critical infrastructure management, urban planning, environmental monitoring, and public safety applications.

While ONGis has been a foundational product for many organizations, ESRI has increasingly focused on its ArcGIS Enterprise platform, which offers a more modern and flexible architecture, often incorporating cloud capabilities. However, ONGis continues to be utilized by many established users who have invested in its infrastructure and workflows. Its legacy lies in providing robust, on-premise GIS solutions that have supported significant spatial data initiatives for decades.
