National Association of GIS-Centric Software






An association of ESRI® Authorized Developers dedicated to:
  • providing Enterprise-GIS solutions;
  • promoting the unique characteristics and benefits of GIS-centric software applications;
  • promoting interoperability, open standards and shared database approaches among GIS-centric software; and
  • distinguishing GIS-centric software and applications from other approaches.


Performance-based Criteria:
  • ESRI GIS geodatabase is the feature database including for storing the feature attributes.
  • Non-redundant feature data storage (no reliance on views, data mapping, database triggers, or "transparent" links).
  • Feature data model is fully user-definable and customizable without vendor support.
  • Non-proprietary feature data model format, including data names, fields, tables, relationships, and other data design elements.
  • Interoperable, providing maximum compatibility with any other GIS-centric application, including concurrent use of the feature database.
  • Feature data coordinate location and connectivity is inherent in feature (or asset) data model, enabling full utilization of the spatial analysis capabilities including linear referencing and events.
  • Feature data is created and maintained using ArcGIS DesktopTM, ArcGIS ServerTM, or ArcObjectsTM tools for editing, including data error identification and correction methods (particularly for linear network and polygonal features) that check for connected nodes, overlaps, missing segments, linear segments, flow relationships and adjacency.
