| Extension | Main Use | |-----------|----------| | Spatial Analyst | Raster analysis (slope, interpolation, suitability). | | 3D Analyst | TIN, LAS (LiDAR), viewshed, 3D feature editing. | | Network Analyst | Route, closest facility, service area (network). | | Geostatistical Analyst | Kriging, IDW, probability mapping. | | Data Reviewer | Automated data quality checks. | | ArcScan | Raster-to-vector conversion (e.g., scanned maps). | | Tracking Analyst | Temporal and trajectory data. | Esri is currently on ArcGIS Enterprise 11
