Representation of 3D Land Cover Data in Semantic City Models
A large number of cities have created semantic 3D city models, but these models are rarely used as input data for simulations, such as noise and flooding, in the urban planning process. Reasons for this are that many simulations require detailed land cover (LC) and elevation data that are often not included in the 3D city models, and that there is no linkage between the elevation and land cover data. In this study, we design, implement and evalua…
A feasibility study of applying generative deep learning models for map labeling
The automation of map labeling is an ongoing research challenge. Currently, the map labeling algorithms are based on rules defined by experts for optimizing the placement of the text labels on maps. In this paper, we investigate the feasibility of using well-labeled map samples as a source of knowledge for automating the labeling process. The basic idea is to train deep learning models, specifically the generative models CycleGAN and Pix2Pix, on …

Future Swedish 3D City Models—Specifications, Test Data, and Evaluation
Three-dimensional city models are increasingly being used for analyses and simulations. To enable such applications, it is necessary to standardise semantically richer city models and, in some cases, to connect the models with external data sources. In this study, we describe the development of a new Swedish specification for 3D city models, denoted as 3CIM, which is a joint effort between the three largest cities in Sweden—Stockholm, Gothenburg,…
A BIM-based approach to design a lifecycle 3D property formation process
3D property formation has become an important solution to provide a more comprehensive and accurate representation of the property’s physical characteristics than traditional 2D property formation. Despite the numerous benefits of the 3D property formation, there is a need for more detailed descriptions of 3D cadastral data delivery between the involved actors to ensure efficient and effective collaboration. In particular, the practical difficult…
Versioning of 3D City Models for Municipality Applications
The use of 3D city models is changing from visualization to complex use cases where they act as 3D base maps. This requires links to registers and continuous updating of the city models. Still, most models never change or are recreated instead of updated. This study identifies obstacles to version management of 3D city models and proposes recommendations to overcome them, with a main focus on the municipality perspective, foremost in the planning…
Requirements, Development, and Evaluation of A National Building Standard—A Swedish Case Study
The aim of this paper is to present a proposal for a national building standard in Sweden. We define requirements for the proposed standard, e.g., it should support development of 3D city models, connect to building information models (BIM) and national registers and be based on a national classification system for the urban environment. Based on these requirements we develop an Application Domain Extension (ADE) of the building model in the prop…
Tools for BIM-GIS Integration (IFC Georeferencing and Conversions)
The integration of 3D city models with Building Information Models (BIM), coined as GeoBIM, facilitates improved data support to several applications, e.g., 3D map updates, building permits issuing, detailed city analysis, infrastructure design, context-based building design, to name a few. To solve the integration, several issues need to be tackled and solved, i.e., harmonization of features, interoperability, format conversions, integration of …
Methods to Create a Longitudinal Integrated Demographic and Geographic Database on the Micro-Level
The authors develop a methodology to create databases that can be used to add micro-level geographic context to longitudinal historical demographic analyses. The method transforms geographic objects as snapshots (digitized from historical maps) into temporal representations of longitudinal object lifelines and links individuals to these geographic objects. The methodology is evaluated via a case study using historical data from the Scanian Econom…
Extending the Intermediate Data Structure (IDS) for longitudinal historical databases to include geographic data
The Intermediate Data Structure (IDS) is a standardised database structure for longitudinal historical databases. Such a common structure facilitates data sharing and comparative research. In this study, we propose an extended version of IDS, named IDS-Geo, that also includes geographic data. The geographic data that will be stored in IDS-Geo are primarily buildings and/or property units, and the purpose of these geographic data is mainly to link…
Cartographic Quality Issues for View Services in Geoportals
Following the INSPIRE directive, several countries are now setting up geoportals. These geoportals have view services that offer new opportunities for users to easily display rich and personalized geographic data. However, they also raise new challenges. One challenge is the absence of the traditional cartographer, which sets requirements for the development of automatic methods that optimize the presentation of the data. This article discusses f…
Placing Text and Icon Labels Simultaneously
This paper presents a method of combining text and icon label placement in a real-time computing environment. The method computes label configurations based on placement properties, cartographic disturbance, and label overlap. The process is divided into four phases. In the first phase, candidate positions of the text labels are chosen. In the second phase, the same is done for the icon labels. The choice of candidate positions is based on cartog…
The Constraint Method for Solving Spatial Conflicts in Cartographic Generalization
New methods are needed to automate cartographic generalization. This article presents a method for automating the displacement of vector data, called the constraint method. The framework of the method consists of five displacement behavior types. Each cartographic object type belongs to one of these displacement behavior types, which determines the properties of the object type in the displacement process. The displacement behavior types are spec…
