Special Issue Information
Dear Colleagues,
Contrary to outdoor environments, there is no overall solution based on a single technology for indoor navigation. Challenges include the complexity of the environments, low probability for line-of-sight (LOS) availability, blockage of signals and severe multipaths, and autonomous sensor deficiencies, but also the accuracy, availability, and reliability requirements of the chosen application. Thus, it is not easy to model radio propagation indoors, and therefore, alternative technologies are needed. A large variety of techniques and devices are used to provide indoor navigation, ranging from already deployed reconfigured devices to the use of smartphones. Lights, radio waves, magnetic fields, acoustic signals, and behavioral analytics can be used. For absolute positioning, usually either purpose-built installations with strategically placed relays and beacons throughout a defined space or so-called signal-of-opportunity are employed. Common systems include Wi-Fi (wireless fidelity), UWB (ultra-wide band), Bluetooth, etc. However, digital cameras and LiDAR (light detection and ranging) are being increasingly utilized, as they are nowadays found in mobile devices. Moreover, inertial sensors for relative positioning and navigation using the commonly employed dead reckoning technique are used. To obtain optimal indoor navigation solutions, sensor fusion techniques are also of high importance. The application of indoor navigation ranges from the navigation of persons and objects, such as to help visitors to find their destination in real time without deviations, to finding objects in complex building structures. Furthermore, systems must be able to define and adapt routes for different user groups, such as in the navigation of people with reduced mobility or visual impairment. This Special Issue aims to address these developments and provide insight into the related challenges and strategies for mitigation.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Geomatics is an international peer-reviewed open access quarterly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
