FieldKit

FieldKit is a professional field survey, mapping, and GIS data collection toolbox. No account. No ads. No subscriptions. Zero data collected. Works offline first. Designed for land surveyors, civil engineers, GIS professionals, and field crews. Import total station coordinates, connect external RTK GNSS receivers, digitize maps, calculate earthwork volumes, and export to Geopackage,Shapefile, GeoJSON, or CSV. ────────────────── 📐 TOTAL STATION & CONTROL POINTS ────────────────── Import CSV, SHP, KML, GeoJSON with your actual survey coordinates (Eastings/Northings). Map columns manually. Set UTM or custom CRS. Add ground control points to georeference rasters. No phone GPS approximation. ────────────────── 📍 EXTERNAL GNSS + RTK ────────────────── Connect Bluetooth Classic GNSS receivers (GSOF, NMEA). Built-in NTRIP client for RTCM corrections. View RTK Fixed/Float, satellite sky plot, DOP, and accuracy. Centimeter precision with compatible receivers. ────────────────── 🗺️ MAP WORKSPACE ────────────────── Import Shapefile (SHP with DBF/PRJ/CPG), GeoTIFF, GeoPackage, KML. Raster georeferencing with GCP workflow. Layer control, draw/edit polygons/polylines. Buffer, clip, dissolve, topology validation. ────────────────── 📏 MEASURE & CALCULATE ────────────────── Satellite measurement (ESRI imagery). Image measurement with TFW world file support. Draw canvas. Length/area with Nepali units (Ropani, Aana, Bigha). Coordinate converter (WGS84, UTM, custom EPSG). Compass. ────────────────── ⛰️ ELEVATION & EARTHWORKS ────────────────── Generate DEM from elevation points (IDW). TIN surface. Contour lines. Cut/fill volumes against target elevation. Export DEM GeoTIFF and contour GeoTIFF. ────────────────── 📐 SECTION BUILDER ────────────────── Generate L-section profile and cross sections from alignment polyline. Export to scale PDF (A4 to A1 landscape) with true 1cm grid. Manual scale denominators (1:500, etc.). Ideal for road and pipeline surveys. ────────────────── 🧭 TRAVERSE ADJUSTMENT ────────────────── Apply Bowditch (compass rule) adjustment for closed loops or open links. View misclosure and precision ratio. Export PDF report. ────────────────── 📦 IMPORT & EXPORT ────────────────── Import: CSV, SHP, KML, GeoJSON, GeoPackage, GeoTIFF, TIFF, TFW Export: SHP, GeoJSON, CSV, GeoPackage, PDF, GeoTIFF ────────────────── 🇳🇵 NEPALI TOOLS ────────────────── Ropani/Aana/Paisa/Dam and Bigha/Katha/Dhur units. Bikram Sambat calendar with AD/BS conversion. EMI calculator with Nepali date format. ────────────────── 🧾 OTHER TOOLS ────────────────── Loan EMI calculator with PDF schedule. QR scanner (URL, WiFi, UPI). Scientific calculator with derivatives and integrals. Price per area. Bearing report. ────────────────── 🔒 PRIVACY ────────────────── No account. No internet required for most tools. No data collection. No third-party sharing. No ads. No subscriptions. ────────────────── ⚠️ NOTES ────────────────── Phone GPS: 3-10m accuracy (navigation only). Centimeter accuracy requires external RTK receiver + NTRIP. Total station data works via CSV/SHP with correct CRS. Set UTM zone in Map settings before import.
