InstaPunch Mapper is a field-mapping tool for orienteering mappers on iPad and iPhone. Set up a georeferenced canvas, lay an aerial image or online map underneath, sketch in the terrain with GPS and compass at hand, and export a high-resolution, georeferenced draft, all on one canvas, without bouncing between desktop tools. GEOREFERENCED CANVAS • Draw a box on Apple Maps and the canvas picks its UTM zone automatically • Or build the canvas straight from an aerial image with a JGW world file: scale, paper size and CRS in one step • Paper sizes up to A1; the canvas always keeps metres, paper millimetres and pixels in step • WGS84 / CGCS2000 / UTM; the canvas is always grid-north-up, with magnetic declination handled separately BASE MAPS • Apple Maps satellite and street tiles as an online base map, with an offline cache for the field • Or connect your own XYZ tile service (the API key stays in the device Keychain) • Import aerial images up to 65535 × 65535 px at full resolution, no downsampling • JGW / PGW / TFW / WLD and GeoTIFF coordinates are read automatically; images without a world file are placed with two or more control points • Several base maps line up automatically when their coordinates agree SKETCH ON SITE • Drawing resolution follows the map scale, up to 900 dpi, so what you draw is what prints • Pen widths in paper millimetres (scale with zoom) or screen pixels (constant on screen), with the real-world width shown alongside • Technical pen, ink, pencil, marker and soft brush with Apple Pencil pressure and hover • One stroke, one undo; pinch and rotate the canvas without touching pixels or history • Live scale bar at the bottom of the canvas, with your choice of style and units; unlock it to drag • A quick-action ball in the corner switches between freehand, shapes, eraser and field tools PIXEL AND VECTOR LAYERS • Pixel layers are stored in tiles, so large maps stay smooth • Vector layers keep polylines, Bézier curves, rectangles, ellipses, circles and polygons editable: drag handles, continue, split, close • Rasterize vector shapes into a pixel layer whenever you want • Opacity, lock, visibility and drag-to-reorder for every layer; imported paper sketches with a JGW snap into place GPS, COMPASS AND TRACKS • Your position and accuracy circle are drawn on the canvas; the heading follows the compass • Record GPS tracks with one tap: each recording is its own layer and the original GPX is kept intact EXTERNAL RTK AND CORRECTIONS • Connect a Bluetooth Classic RTK receiver through an InstaPunch Bridge, or a BLE device directly • Use this device or the RTK receiver as the position source; the canvas location and track recording follow the receiver, with fix type, satellites and accuracy shown live • NTRIP 1.0 / 2.0 (CORS) corrections, with the account password kept in the device Keychain • Multi-leg measurements label every segment with length and bearing, in paper millimetres and real metres EXPORT AND BACKUP • PNG / JPG / TIFF / BMP at 300 / 600 / 900 dpi or any higher resolution, with a matching JGW world file • Exports open georeferenced in OCAD, OpenOrienteering Mapper and other desktop mapping tools • Paper presets or free framing, AirPrint PDF printing, GPX export for tracks • Auto-save, history snapshots and automatic backups; share and import projects as .ipmproj files • Project browser with folders, colour labels and search Your projects, tracks and location stay on your device. No account, no ads, no tracking. Interface in English and Simplified Chinese, switchable from the project library. ## Is InstaPunch Mapper safe?
