iMapIt Lite vs SW Maps

Use your iPhone / iPad's GPS to map, measure or simply record places important to you. Your device will be a GPS receiver and will collect geographic coordinates wherever you are. GPS needs satellite’s visibility. Thus, the more open your space, the better the accuracy of measurements. * Geographic coordinates collection formats: . Points - Mark specific places with a point, such as the place you most like to go to, or the starting point of a race, or even the point where you saw a rare bird; . Lines or paths - A sequence of points forming a line to mark a trail where you have walked, or the path you have taken on a run, or the path to your new house, either the location of a new fence you want to build. All mapped lines are measured for you in metric and imperial units; . Areas or polygons - A sequence of points, forming a closed region, to mark land that you are interested in buying, or show the map of your land, or measure the outline of your new house, or delimit the region where you want to build a pool. All mapped areas are calculated for you in metric, imperial and Thai units; The LITE version measures line’s length or polygon’s area of your FIRST survey only. * How to collect coordinates: . Manually: You position yourself and tap the MapIt button to collect a coordinate; . Automatically by Time: A coordinate is collected at each defined time interval; . Automatically by Distance: A coordinate is collected at each interval of a pre-defined distance; . Automatically by Direction: A coordinate is collected each time you change the direction of your displacement at an angle greater than a defined limit; * Presentation within iMapIt: Points, lines and polygons can be represented by different types of pins, colors, strokes and fills. * Export your surveys: . Available only in Pro version; * Editing functions of surveys performed: . Feature duplication; . Union of existing features; . Division of a feature in two; . Deletion of unwanted coordinates; . Automatic cleaning of unnecessary points; . Move a feature to a new project; Disclaimer on the accuracy of the surveys: All points, paths or areas are surveyed using the GPS accuracy of your device. This is not a professional precision GPS equipment. So your surveys may vary when compared to the actual dimensions. Restrictions of the LITE version: The export of collected data is not allowed. The length of the paths and the size of the mapped areas are calculated only for the very FIRST survey. Ads are presented in map screen.

SW Maps is a free GIS and mobile mapping app for collecting, presenting and sharing geographic information. Whether you are conducting a full scale GNSS survey with high precision instruments, need to collect large amount of location based data using nothing but your phone, or just need to view a few shapefiles with labels over a background map on the go, SW Maps has it all covered. Record points, lines, polygons and even photos and have them displayed over your choice of background map, and attach custom attribute data to any feature. Attribute types include text, numbers, an option from a predefined set of choices, photos, audio clips and videos. Conduct high accuracy GPS surveys using external RTK capable receivers over Bluetooth LE. Draw features on the map by adding markers, and measure distance and area. Reuse the layers and attributes of a previous project for another survey, or create templates and share them with other users. Share the collected data with other users as Geopackages, KMZ or shapefiles, or export them to your device storage. Also share and export recorded data as Spreadsheets or CSV files. All data is recorded and exported in the standard WGS84 Geographic coordinate system (EPSG:4326). Features -Online Base maps: Apple Maps or Open Street Map -Support for multiple mbtiles and KML overlays -Shapefile and Geopackage layers, with attribute categorized styling. View shapefiles in any coordinate system supported by the PROJ.4 library. -Add multiple online WMTS, TMS, XYZ or WMS layers and cache tiles for offline use. -Connect to external GPS receivers using Bluetooth for high accuracy surveying using RTK with built-in NTRIP client. Also record data from external receiver for post processing. -Define multiple number of feature layers, each with a set of custom attributes Feature Types: Point, Line, Polygon Attribute Types:Text, Numeric, Drop down Options, Photos, Audio, Video Save as Template for re-use or sharing -Record GPS tracks, with distance measurement -Label features based on attribute values. -Import feature layers from templates or existing projects. -Share or export collected data as KMZ (with embedded photographs) , shapefiles, GeoJSON, Geopackage (GPKG), XLS/ODS spreadsheets or csv files. -Share templates or projects with other users -Supports use of GTX geoid files. To use custom geoids, prepare a GTX file with offsets in meters from WGS84. This product is made in Nepal and is FREE (no Ads).
