iGIS - The world's first and leading iOS GIS. True GIS functionality is now available on the iPhone! Your iPhone. Your data. Your maps. iGIS represents a new era in mobile GIS solutions by enabling users to load, view, investigate, create and export their own data over a background of map service imagery. Importing data is easy with our unique data import facility using the USB cable or wirelessly on your Mac, PC and Linux. Raster data in many formats (pre-processing required) and ESRI Shapefiles (.shp) are supported at the moment. 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. We include support for multiple layers of points, lines, and polygons – all styled as you like. Imagery layers too in V5. Add comments to your maps - A point layer is added with a name and description field. Add and edit your own layers, via the map display and customisable data entry forms. Export your layers to ESRI shapefiles for use back in your enterprise. Other features include: - Great speed, using our multi-threaded map renderer. - Support for large datasets. - Import and export of ESRI Shapefiles. - Display current GPS location in your chosen projection ( + compass) - Zoom to current location - Zoom to data extent - Map Pan, zoom in, zoom out - Changeable drawing styles for a layer: size, color, transparency - Set the draw order and visibility of map layers - Set the zoom scale for layers via a simple slider - Select and interrogate feature attributes via point and click This application is designed for GIS professionals and an understanding of some basic GIS concepts such as layers, shapefiles, projections etc, would make using iGIS simpler. Please let us know if concepts in iGIS are unclear. Continued use of GPS running in the background can dramatically decrease battery life.

System Requirements: - iOS 13.0 or higher Description: Locus Mobile for iOS works in conjunction with Locus’ environmental information management systems. The mobile application is used for simple and accurate data collection and upload from the field, and in the process improves workflow, enables productivity gains, ensures accuracy, and leverages location intelligence. Interaction with Locus Mobile does not require a real-time data connection, and content from the field is uploaded when it is convenient. Field users can work in remote locations with the assurance that all entries are saved and then synchronized back to a secure storage location once they are able to obtain Wi-Fi or cellular data service. Field data collection requirements and sophisticated data entry rules are configured from within Locus’ system and then assigned to field users and enforced through the mobile device. Field data entries are validated upon entry, and the user is provided with guidance on expected field measurement values. Once data are collected they are uploaded to the parent system for review, analysis, and reporting purposes, where they can also be easily audited for compliance support. Mobile users are presented with an interactive map interface that shows where sampling locations are and provides status information regarding the required data collection program. The interface supports ad hoc sampling activities that allow users to add sample locations and complete new data entry events. Locus Mobile application users can take advantage of the inherent location intelligence that has been built in: - The app is built around a map interface - Where do I need to go - Where have I been - Where am I now - Status of data collection/sampling is immediately evident using labeling and color coding - Add new locations on the fly – in the field (ad hoc) - Locations can be dragged/moved to refine placement - Delete and start again - Use satellite background images for improved context Locus Mobile can be used for processing field data collection operations for multiple users working within the same program. The system can be configured for a wide range of measurements related to well monitoring, air sampling and soil sampling. Locus Technologies clients are required to opt in to using the Locus Mobile application in conjunction with the client’s Locus environmental information management systems. Locus mobile users are required to obtain a user account from Locus Technologies in order to log into the Locus Mobile application. The app does not require users to submit payment for content or services within the app. Access and user accounts to the app are granted by Locus Technologies. Contact Locus Technologies via email at info@locustec.com for more information. The app is primarily meant for distribution in the United States. About Locus Technologies: Locus provided businesses with the power to be green on-demand since its founding in 1997. Locus' cloud software enables companies to organize and validate all key environmental information in a single system, which includes analytical data for water, air, soil, greenhouse gases, sustainability, compliance, and environmental content. Locus software is delivered through Cloud Computing (SaaS), so there is no hardware to procure, no large up-front license fee, and no complex set-ups. For more information email info@locustec.com.
