each room; display the schedule and announcements of each department; and provide
other customized services based on the user's profile and preferences.
The main contributions of this paper are as follows:
- We present the concept and design of InMaps, a framework for creating
intelligent maps using 2D-3D maps, indoor location, and IoT technologies.
- We describe the architecture, techniques, and implementation of InMaps,
including the data model, map rendering engine, location service, information service,
and user interface.
- We demonstrate the application of InMaps to make a campus map for the
Vietnam - Korea University of Information and Communication Technology (VKU).
The rest of this paper is organized as follows: Section 2 reviews the related work
on web mapping technologies and intelligent maps. Section 3 introduces the
architecture, techniques, and implementation of InMaps. Section 4 presents the case
study of making a campus map for VKU using InMaps. Section 5 concludes this
paper and discusses future work.

2 Literature Review

2.1 Definition and characteristics of intelligent maps

An indoor map is a digital map that visualizes an indoor venue and spatial data on a
2D or 3D map. It allows for indoor positioning and navigation, as well as other use
cases such as asset management, security, and visitor experience. Some examples of
indoor maps are Google Maps for malls, airports, stadiums, and transit centers;
ArcGIS Indoors for universities, hospitals, convention centers, and factories; and
WRLD 3D for creating custom indoor maps [1, 2].
An intelligent map is a type of web map that can dynamically adapt to different

location, language, preferences, and interests. It can also provide interactive features
such as pop-ups, sliders, swipes, and legends to help the user explore and understand
the data. An intelligent map can become a story map by adding supporting content
such as text, photos, videos, and audio that explain the purpose and meaning of the
map [3].
In our paper, we will introduce InMaps, an indoor map contains the characteristics
of intelligent maps.

2.2 Related works and frameworks for intelligent maps

As smart cities, digital twins, or the metaverse evolve, there is a higher need for
more efficient spatial information collection, processing, modeling, display, and
visualization of indoor environments. Indoor space is different from outdoor space
because it is usually limited and restricted by architectural structures [4]. The
structural complexity of buildings and indoor location-based applications pose
challenges that have increased the interest in indoor mapping and surveying.
