Field Sentinel Mapper

Field Sentinel is a professional geospatial platform for iPhone and iPad, built for teams who work where connectivity is unreliable or unavailable. Whether you support defense operations, emergency response, surveying, construction, aviation, or remote field research, Field Sentinel puts maps, GIS tools, and intelligence workflows on a single device—fully offline when you need it. WORK WITHOUT THE NETWORK • Render offline maps from GeoPackage, MBTiles, and PMTiles • Run spatial queries with SpatiaLite against local feature data • Design and edit schemas, tables, domains, and relationships in GeoPackage • Collect field data with XLSForm-compatible forms and barcode scanning • Import and export KML, KMZ, GPX, GeoJSON, Shapefile, and more PROFESSIONAL MAP & GIS EDITING • Snap-aware vertex editing with split, merge, reshape, and erase tools • Digitize points, lines, and polygons directly on live map layers • Redline annotations, symbols, and labels with GeoJSON/KML export • Terrain analysis including viewshed, slope, elevation, and 3D terrain viewing • GDAL-powered format conversion for raster and vector data ON-DEVICE AI ASSISTANT • AI chat and report drafting powered by local language models • Natural-language spatial queries against your map data • Image analysis for terrain and damage assessment from photos • Document Q&A from PDFs and field documents—processed on your device SITUATIONAL AWARENESS & COMMUNICATIONS • Team Awareness Kit (TAK) client with Cursor-on-Target messaging • GeoChat, mission packages, and live position sharing when connected • Fleet and asset tracking with proximity alerts • Optional integration with TAK Server for team coordination FIELD OPERATIONS MODULES • Surveying: COGO, traverse, leveling, area/volume, and GNSS/RTK support • Construction: earthwork, CAD/DXF overlay, BIM/IFC viewing, and PDF reports • Aviation: FAA charts, airspace layers, TFRs, flight planning, and NOTAMs • Emergency management: ICS/NIMS forms, CAP alerts, and damage assessment tools • Intelligence workflows: GEOINT analysis, change detection, and multi-source fusion BUILT FOR THE FIELD Field Sentinel is optimized for iPad and iPhone in portrait and landscape. Store tile packages, models, and databases on device. Generate professional PDF reports in the field. Use split-screen workspace tools for documents, notes, and annotations alongside your map. Field Sentinel is developed by Tech Maven Geospatial—bringing enterprise GIS, tactical awareness, and on-device intelligence to operators at the edge. Privacy: Core workflows run on your device. Network access is optional and used only for features you enable, such as TAK Server sync, chart downloads, or imagery updates. Questions or enterprise licensing: contact Tech Maven Geospatial.
