Offline GIS surveying, census mapping, and GPS tracking tool for field agents.
Streamline your field data collection, census operations, and GIS land mapping with the ultimate offline-first mapping tool built for field surveyors, census agents, and GIS professionals. Whether you are mapping house numbers for census blocks, tracking parcel boundaries, drawing roads, or conducting property surveys, this app offers a robust, offline-ready suite of tools designed to work in remote areas without internet dependency. ### KEY FEATURES: โ OFFLINE-FIRST GIS MAPPING Never worry about losing connection in remote fields. Download and work with offline map tiles, local SQLite storage, and complete vector feature mapping (points, polylines, polygons) entirely offline. โ ACCURATE GPS TRACKING & SMOOTH PATHS Record walk paths and driving tracks in real-time. Built-in Kalman filtering algorithms smooth out raw GPS jumps and jitter to deliver clean, accurate roads and boundary tracks. โ AUTO-INCREMENTING HOUSE NUMBER SEQUENCE Add housing structures with a single tap. The app auto-increments house number sequences (e.g. H001, H002) in your walking direction. Offset buildings automatically based on device heading using the built-in compass compass orientation. โ SHAPE & BOUNDARY DRAWING Easily draw roads, property lines, and boundary zones. Drag and drop coordinates to modify shapes on the go. Tap corners to define customized PDF print areas. โ SATELLITE & STANDARD BASEMAPS Toggle between standard OpenStreetMap layers and high-resolution Esri World Imagery (satellite basemaps) to verify structures, landscape bounds, and physical terrain. โ PROFESSIONAL BLUEPRINT EXPORT (PDF) Export premium, official-grade blueprints and field maps in high-resolution PDF format (supports A3 dimensions and multi-page grid structures). Share maps directly with team members or print them for physical documentation. โ BACKUP, DIAGNOSTIC, & DATA CONVERSION Seamlessly export or import survey data via JSON. Built-in diagnostic utilities automatically detect and repair geometry issues to ensure full compatibility with modern GIS standards. ### PERFECT FOR: - Government & Non-Profit Census Field Agents - Land Boundary Surveyors & GIS Technicians - Cadastral Mapping & Property Valuers - Infrastructure & Road Planning Crews - Agriculture Field & Forest Boundary Trackers Download today to turn your mobile device into a professional, offline-capable GIS surveying and mapping powerhouse!
