- Geographical accessibility is fundamental when planning rescue services. At present there are several programs for computing the accessibility of stationary rescue units. This study suggests a method for evaluating geographic accessibility in scenarios containing also non-stationary units. The method supports the planning process by matching the risk of an incident occurring with the rescue units’ capabilities and accessibility. The method is implemented in the computer program Rescue Unit Planner. The result of the analysis is presented in thematic maps and graphs as level of coverage, mean response time and concentration. The method and the computer program have been evaluated in two case studies: one urban area in southern Sweden and one rural area in northern Sweden. The case studies show that that this method can be useful in the rescue service planning process.

Techniques for and consequences of using INSPIRE extensions : a case study with Swedish hydrological data
- 2018

Tidskriftsartikel (refereegranskat)abstract
- The demand for easily available geographic information is increasing in society. Moreover, knowledge of spatial data infrastructures (SDIs) has increased in many European governmental agencies, in large part because of the implementation of the INSPIRE directive. Many countries, thus, recognise the need to provide more detailed geographic information as network services at the national level. One means of realising this goal is to create INSPIRE extensions, i.e., to extend the INSPIRE data specifications with more detailed and specific national information. This paper describes a study where a complex INSPIRE extension has been created to describe the national need of hydrography information in Sweden, based on the Swedish water system standard (SWSS). The study includes the creation of a UML application schema that extends the INSPIRE Hydrography (HY) theme, the transform from UML to an XSD schema, the creation of GML files, and finally, testing and evaluating the approach of using INSPIRE extensions. When evaluating the results, the consequences of replacing existing dataset/download services with one extended INSPIRE HY dataset/download service are evaluated from the perspectives of both users and data providers. The evaluation is carried out as quantitative tests of the resulting GML files, in a user-centric test where a user tests the applicability of the GML files in hydrological analyses, and by telephone interviews with personnel from Lantmäteriet, the Swedish mapping, cadastral and land registration authority. Beside these evaluations, the possible effects on the information modelling process when creating an INSPIRE extension are also examined. The study shows that it is possible to create complex INSPIRE extensions that include many object types, attributes and relations. From a user perspective, extended INSPIRE HY files do not differ substantially from SWSS files, and can be used in hydrological analyses. Data providers can relatively simply replace their current download services with one for the extended INSPIRE HY, but the specific economic consequences for this could not be drawn. It could be expected, though, that there can be both economic, administrative and maintenance advantages if today’s separate INSPIRE and national download services are replaced with services exposing datasets based on an extended INSPIRE data model for all adequate themes.

Some strategic national initiatives for the Swedish education in the geodata field
- 2014

Konferensbidrag (refereegranskat)abstract
- This paper describes national cooperation in Sweden launched by its universities and authorities, aimed at improving geodata education. These initiatives have been focused upon providing common access to geodata, the production of teaching materials in Swedish and organizing annual meetings for teachers. We argue that this type of cooperation is vital to providing high quality education for a poorly recognized subject in a country with a relatively small population.

A BIM-based approach to design a lifecycle 3D property formation process : A Swedish case study
- 2023

Tidskriftsartikel (refereegranskat)abstract
- 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 difficulties are when/what related 3D cadastral information and models should be exchanged and stored from/to whom. Therefore, to address these issues, we propose a lifecycle 3D property formation process with four phases by designing an IDM process, which is an international open BIM process standard. In the purpose of forming a Swedish lifecycle 3D property formation process, the IDM process has been applied through organizational, legal and technical aspects, including identifying actors and their roles and values, gathering 3D property formation requirements, defining the data exchange requirements and designing the process map. Moreover, a case study was used to specify the Swedish lifecycle 3D property formation process and information delivery between stakeholders in the IDM. The aim is to facilitate a standardized and unambiguous digital 3D property formation procedure on a national level in order to improve and enhance the digital Swedish Cadastral and Land Administration Systems, but the process is quite generic and could also be applied in other countries.
