This is demonstrated by the comparison of these two data collection methods.

When examining how Southern Norway's environment has influenced individuals, PPGIS offers a chance to record a variety of viewpoints and local knowledge that would be overlooked using only conventional research techniques. Researchers can obtain a more comprehensive understanding of how locals perceive, engage with, and profit from the natural ecosystems in this region by embracing public participation in GIS activities. In addition to improving data accuracy, this cooperative method empowers and engages the community in protecting and promoting the importance of nature for human well-being.

When examining the contributions that nature has made to people in Southern Norway, comparing PPGIS with crowdsourced spatial data from sites such as Flickr highlights the many advantages and disadvantages of each approach. While there are distinct advantages to both methods—such as scalability with Flickr data and rich local insights with PPGIS—researchers must carefully assess which strategy best matches their interests and study objectives. The comparison of these methods highlights the necessity of a well-rounded research methodology that values community involvement and qualitative understanding while utilizing technology in order to conduct a thorough examination of the relationship between humans and nature in this area.

4. Case Studies: Applying Crowdsourced Data vs. PPGIS in Southern Norway

Crowdsourced spatial data from Participatory Public Geographic Information Systems (PPGIS) and Flickr have been used in Southern Norway to get unique insights into the role that nature plays in human welfare. Now let's examine a few case studies that demonstrate the use of these two strategies.

Case Study 1: Crowdsourced Data from Flickr

In one instance, the popularity and perceived beauty of hiking paths in the Hardangerfjord region was examined using data gathered from Flickr users. Researchers were able to determine which routes were the most popular and aesthetically pleasing by looking through geotagged images that users had posted. Based on user preferences, this information helped local officials determine which regions required conservation initiatives or infrastructure upgrades. The findings provided information about tourist behavior and preferences, which aided in the development of more focused management plans for the growth of sustainable tourism.

Potential biases in user demographics and photo content were a challenge when using Flickr data because not all users may use the platform or post photos equally. Measuring the real impact of nature experiences only by looking at the aesthetics of images might be restrictive because it leaves out other senses that are important for overall wellbeing.

Consequences: Although it has its limits, using crowdsourced data from websites such as Flickr can provide insightful information about visitor behavior, preferences, and views of the environment that can guide sustainable management techniques in Southern Norway's natural areas.

Case Study 2: Participatory Public Geographic Information Systems (PPGIS)

In a different case study, locals' opinions of the ecosystem services offered by Kristiansand's urban green spaces were mapped using a PPGIS technique. Residents prioritized and highlighted a range of benefits from these green areas, including support for biodiversity, improved mental health, and recreational activities. These benefits were determined through participatory mapping exercises and community workshops. Citizens were given the opportunity to express their needs and opinions regarding the value of urban nature beyond its monetary equivalent through the collaborative mapping process.

The PPGIS project's results identified particular urban green places that inhabitants really loved yet were either underutilized or lacked sufficient amenities. Policymakers were able to better match these regions with community preferences and promote social cohesion and local management of green infrastructure thanks to the guidance provided by this information.

Ensuring inclusive involvement from a variety of stakeholder groups and resolving any technological obstacles to efficiently using the mapping tools were challenges associated with PPGIS. It took considerable thought to translate community feedback into policy that would balance the needs of the environment with the aspirations of the local population.

Implications: Through PPGIS projects, decision-makers can better understand how people perceive and use urban green areas by incorporating local knowledge. In addition to supporting more comprehensive planning techniques that give priority to nature-based well-being solutions, this participatory method fortifies social bonds between locals and their surroundings.

Taking into account everything said above, we can say that when examining the role that nature plays in the lives of people in Southern Norway, both participatory methods like PPGIS and crowdsourced spatial data from sites like Flickr provide insightful information.
