QField focuses on efficiently getting GIS fieldwork done and exchanging data between the field and the office in a comfortable and user-friendly way. QField has won the prestigious Best of Swiss Apps Award 2022 in the enterprise category and thanks to its native integration with QFieldCloud, your fieldwork will be as efficient as possible. Built on top of the popular QGIS open-source project, QField lets users consume fully configured projects in the field, allowing for customized feature forms, map themes, print layouts, and more, bringing the power of QGIS to your fingertips. Leveraging open source libraries such as gdal, SQLite and PostGIS, QField reads, displays and allows editing of a wide variety of spatial vector and raster datasets. Users can view and modify datasets wherever they are, whether they have been downloaded onto your device, shared in emails or transferred via USB cable. The supported formats include: - QGIS project files (.qgs, .qgz, as well as geopackage-embedded projects); - SQLite-based geopackage and spatialite databases; - GeoJSON, KML, GPX, and shapefile vector datasets; - GeoTIFF, GeoPDF, WEBP, and JPEG2000 raster datasets. Looking for missing capabilities? OPENGIS.ch is happy to help with the implementation of new features. Contact us at https://www.opengis.ch/contact/ Permissions --- QField can use location permission to draw a marker overlaying device location on top of spatial projects and datasets. QField can also display and use location details such as latitude, longitude, elevation, and accuracy while entering data.

WHAT YOU CAN DO • Open .inp files from Files, Mail, AirDrop or cloud storage • Run a hydraulic simulation and step through the time periods • See the network on an interactive map: zoom, pan, touch and hold any node to see its data • Read pressure, head, demand, flow, velocity and headloss for junctions, pipes, pumps, tanks, reservoirs and valves • Review hydraulic and time options • Works offline. Your files stay on your device EDIT IN FLOWANALYZER Tap "Edit & simulate in FlowAnalyzer" on the network screen to send the network to FlowAnalyzer (if installed) to edit it. If FlowAnalyzer is not installed, its App Store page opens inside the viewer. The two apps are separate. They use different EPANET engine versions (2.2 and 2.3.5); results may differ. FREE FlowAnalyzer Viewer is free, with no limit on network size. To edit and create networks, there is FlowAnalyzer. PRIVACY No account, no ads, no tracking. The app collects no data. FlowAnalyzer Viewer uses the EPANET 2.2 engine to read and simulate .inp files.
