GIS Lite vs SW Maps

GIS Lite. Use your iPad and iPhone to open DXF, KML, Shapefiles, GeoTiff, WorldFiles and more. Collect data on the field, attach photos and share pdf item reports. Take freehand / pencil notes over maps and export georeferenced tiff. Features that support property view available. New updates will gradually add features that will transform your device to a complete GIS station. GIS Lite is a professional mobile GIS solution that enables users to load and view heir own data over a background of map service imagery. Open of various vector data formats is supported. Below a list of current support types. ** For formats that use support files (eg dbf for shapefiles), files must be in the dedicated iCloud/GIS_Lite folder, so that access is provided to the application. Raster Files * #GeoTiff GIS Lite can open and render your GeoTiff files directly on the map. #WoldFiles** Open PNG, JPG or TIFF file using the corresponding world file (pgw,jpw,tfw). Just specify the projection used. Vector Files #DXF files .dxf Select your file to open from local or iCloud storage. You will need to select data projection. Layers and styles will be loaded. #KML / KMZ files .kml / .kmz #ESRI Shapefiles .shp Select .zip file that contains .shp, .dbf, .prj files Or Select your .shp file to open from local or iCloud storage. If you want a full load (.dbf attributes and .prj file), the files must be copied in iCloud application folder (GIS_Lite). If not, you can still view your data. In that case, only geometry will be loaded and you will have to define projection. Rendering of geometry primitives is currently available (points / lines / polygons) Parsing engine is continuously updated so stay updated for more features. Create datasets by collecting data on the field. Capture on field photos and attach to polygon / line / point record. Version 1.6 introduces Apple Pencil usage for enhanced object selection. Your spatial data is stored on the iPhone, so there’s no need for an Internet connection to see your data – great for field work. We also support over 3000 projections, so no need for re-projection. Change Basemap among apple map / satellite / hybrid and more. This application is optimised to provide • High parse and render speed • Zoom to extend • Zoom to selection • Select objects on map • Display attributes • Highlight selection items • Extensive projection list • GPS position • Export and share selected objects Some basic GIS background is assumed to be able to use the application (projections, layers, etc) *Images loaded are currently restricted to 2 MegaPixel size for performance reasons.

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).
