This chapter focuses on mapping activities, specifically open field mapping tools that are utilized to analyze environmental and humanitarian topics. Open field mapping tools such as Vespucci or GoMap give access to the OpenStreetMap database, allowing the public to contribute and access and edit environmental information. This helps to better understand and utilize climate change and find solutions. The public accessibility of the database has a broad range of uses, such as disaster relief, humanitarian aid, and environmental conservation efforts. Also we will learn Field Papers which provides analog field mapping with possibilities of digitizing paper maps. So, in this chapter, we will deal with such tools and learn how to use them in mapping local environmental issues.
