About this app

Mapwright opens your GIS files on your phone or tablet — no account, no cloud, no subscription.

Open a Shapefile from an email, a GeoPackage from your drive or a KML a client sent you, and see it on a fast, clean map in seconds. Walk the site with GPS, check attributes, measure, sketch new features and send the data back in the format your desktop GIS expects.

OPEN THE FILES YOU ALREADY HAVE
• Shapefile (.shp with .dbf, .shx, .prj — or a zipped set)
• GeoPackage vector layers
• KML and KMZ
• GeoJSON
• GPX waypoints, tracks and routes
• CSV with latitude/longitude or X/Y columns
• GeoTIFF rasters

COORDINATES DONE PROPERLY
• Reads the coordinate system from .prj files, GeoPackages and GeoTIFFs and reprojects on the fly
• Built-in list of common systems: UTM zones, British National Grid, State Plane, Lambert-93, Gauss-Krüger, LV95, RD New and more
• Show positions as decimal degrees, DMS, UTM, MGRS or any projected system
• Tested against reference values from standard GIS tools

A MAP THAT WORKS IN THE FIELD
• Smooth vector base map in light and dark styles
• Download areas for offline use before you lose signal
• Add your own XYZ tile source or MBTiles base maps
• Style layers by colour, width and fill, or by attribute categories, with labels
• GPS position with its real accuracy shown as a circle and in metres

LOOK INSIDE YOUR DATA
• Attribute table with sort, search and filter
• Tap a feature on the map to see every field
• Measure distances and areas on the ellipsoid, in metric or imperial, hectares or acres

PRO — ONE PAYMENT, YOURS TO KEEP
• Edit: add points, lines and polygons, move vertices, edit attributes with a generated form, attach photos
• Average several GPS fixes for a steadier point
• Record tracks while you walk
• Export to Shapefile, GeoPackage, GeoJSON, KML/KMZ, GPX or CSV, reprojected to the system you choose
• Connect an external Bluetooth GNSS receiver (Android) for survey-grade positions
• Unlimited layers and offline areas, no ads

PRIVATE BY DESIGN
Your files stay on your device. Mapwright has no sign-in and does not upload your data anywhere.
