Digital solutions for your site

Our customers

The digital guide for your site.

The "Site Guide" can be used in two ways:

Your own app


Get an overview of your position and all accessible buildings/locations. With search function and filter you will find your destination.


Additional information and media content are presented to inform the user in advance about the "Points of Interest".


Integrated navigation for pedestrians, cars and trucks with modifiable road network, taking construction zones or restricted areas into account.

Site Guide navigation app on your site

Are your visitors/suppliers still navigating with printed maps?

Just point out to in visitor invitations, delivery documents, e-mails or at the gate and your employees, visitors or suppliers can quickly and easily find the way to their destination using the Site Guide navigation app. The app automatically detects that the user is on your site and then provides a safe navigation to all your desired buildings/POIs.

Fast & flexible

The support of the Site Guide navigation for your site can be set up within a very short time. All of your desired routes and any special features (one-way streets, construction zones, explosion protection zones, speed limits etc.) can be taken into account. The navigation is available for pedestrians, cars and trucks and can be used worldwide on any outdoor site.

Please choose your industry:

Industry & Business

Use your own app based on the Site Guide to guide your visitors, suppliers, or employees from the gate to the appropriate building or loading point along routes that you have previously defined.

Together with your experts from marketing, logistics, facility management or factory safety, we analyze the processes involved in visiting your site. The spectrum of analysis ranges from the pedestrian guest to the supplier truck and from the visitor invitation by e-mail to the orientation on your site. Together, we discover optimization potential and develop strategies to solve any problems.

User voice

„This app is a milestone. Every plant should have one. For more than 25 years, I have been driving in chemical transport with a 40-ton truck and site maps are not always easy to read. This app is very good.“
Written feedback from a truck driver after using the Site Guide, 25.08.2017, Hürth

Construction Zone Management

Whether as part of your Site Guide app or as stand-alone solution - with the digital construction zone managament by Tagxter you will always be able to keep an eye on all construction activities and other restricted areas on your site. You can also embed them into your internal corporate communications. Possible use cases:

  • Road closures
  • Building works
  • Events
  • Crane stances
  • Accident scenes
  • Track works
  • Explosion protection zones
  • ...

The dynamic overview map is web-based and can therefore be used almost everywhere, for example on the intranet via PC or on the go on your smartphone.

For all construction zones and special areas on your site, you can add extensive information and contact persons, which can be reached with just one click. The zones can be scheduled exactly and are (de)activated automatically at the specified time.

Different accesses with various authorizations and workflows can be created for different departments (factory safety, facility management, fire brigade etc.).

Your construction zone management will reach its full potential if you use the Site Guide apps on your site. All information about construction works can be automatically imported into your Site Guide.

The route calculation of the app also automatically takes into account all closures for the selected means of transportation (car/truck/pedestrian) and selects the fastest alternative route. Therefore, you no longer need to worry about how to communicate temporary closures and necessary diversions to all persons on your site - the Site Guide serves as a central information portal.
