Perfect Companion to Locus GIS

Our app serves as the perfect companion to ArduSimple hardware. The ArduSimple connection is plug-and-play, requiring minimal setup time. This means less fiddling with equipment and more time collecting valuable data. 

For detailed instructions on how to connect Locus GIS to devices like ArduSimple, check out our comprehensive manual. This guide walks you through the process step-by-step, ensuring you can get up and running quickly.

Real-world Impact

For GIS professionals, the combination of ArduSimple and Locus GIS opens up new possibilities. Whether you’re mapping utility infrastructure, conducting environmental surveys, or managing agricultural lands, the enhanced accuracy translates to better decision-making and more reliable spatial data.

The affordability of ArduSimple devices, coupled with their professional-grade performance, makes high-precision surveying accessible to a broader range of users. This democratization of technology allows smaller organizations and individual professionals to compete on a level playing field with larger, more established entities.

Reforestation and conservation efforts require accurate mapping of existing meadows. The Locus GIS application has proven to be an invaluable tool for this purpose.

The process starts with aerial photos, provided by the WMS Service Hessen, which provide a comprehensive overview with boundaries. However, these photos often lack the detailed information needed for effective mapping, such as the presence of swamps, springs, and specific tree populations and species.

To capture these details, a smartphone is used to conduct a field survey with an accuracy of about three meters. Field data is meticulously cataloged by object and determined in the field.

One of the key features of Locus GIS is the ability to export data directly from the field as shapefiles, which can then be sent to the office for further processing. This data is easily imported into GIS software such as QGIS for detailed analysis and application.

The app’s ability to save photos and edit objects greatly enhances the workflow, making subsequent tasks much easier. Overall, the efficient mapping provided by Locus GIS has saved considerable time in the reforestation planning process.

We are pleased to announce the latest version of our LocusGIS application, which includes a number of useful features for users who require high precision work. The new application offers the NTRIP client, which allows users to set tolerances (warning in case of insufficient accuracy) and also set the height of the datum. All important parameters related to GNSS setup can be found in the new GNSS manager.

NTRIP Client

NTRIP (Networked Transport of RTCM via Internet Protocol) is a protocol for the transmission of real-time GNSS corrections over the Internet. The NTRIP client enables the reception and implementation of this data in GNSS receivers, thereby significantly enhancing positional precision. The type of device in question will determine the level of accuracy achievable with the corrections in question, with centimeter accuracy in position and height being a possibility.

How does the NTRIP client work in LocusGIS?

The integration of the NTRIP client into our LocusGIS application provides users with the ability to receive real-time GNSS corrections without the need to use other applications. It is essential to use a Bluetooth GNSS antenna that supports correction processing. Additionally, it is necessary to establish a connection to an NTRIP server (caster) that provides real-time corrections in your area. The application establishes a connection to the NTRIP server, downloads the corrections, and provides them to the GNSS antenna, which then obtains the refined data.

Precise application usage for your needs

With NTRIP client support, the LocusGIS application is the ideal tool for anyone who needs to work with high accuracy positional data. Such as surveying, precision mapping, agriculture, construction, etc.

Tolerance manager

In addition to the NTRIP client, we have incorporated a new feature called Tolerance manager into the latest version. This feature enables users to specify the minimum required accuracy in position and height, the number of satellites used to obtain the position, the PDOP (Position Dilution of Precision) value, and the solution.
Upon saving a new point, the application verifies the set tolerances. If any of these tolerances are not met, the application displays a warning dialog to inform the user about the lack of accuracy. The user has the option of reacquiring the position or saving the point despite the lack of precision, should they wish to do so. This feature provides users with greater control and confidence in their data acquisition.

Adjusting the height of the pole and phase centre

When working with a precision GNSS antenna, it is of the utmost importance to ensure that the height of the pole is correct. This feature allows users to set the pole height and phase center, which is beneficial for those who require this functionality. The application automatically corrects the measured elevation based on these values.

We are confident that the Locus GIS 1.22, which includes a built-in NTRIP client and tolerance manager, will assist you in achieving greater accuracy and precision in your work, thereby enabling you to reach new heights in your performance goals and improve your overall work effectiveness.
