| Popis: | The Maricá Coastal Plain, in the state of Rio de Janeiro, Brazil, is formed by a sandy barrier system, up to 120,000 BP, covered by Atlantic Forest coastal vegetation. Its central area is designated as the Environmental Protection Area (APA) of Maricá. Here, we develop a digital poster (interpretation board) to highlight the geological importance of the site. Such geiointerpretation aims to provide opportunities to experience landscapes indirectly through the use of secondary sources of spatial information. The digital poster is a tool to be used by the site management site to assist public awareness of environmental issues through geographical and geological interpretation. The starting point of this project was a drone survey to acquire aerial photographs of APA Maricá to generate high-resolution 3D images through image processing at low cost. To represent the geomorphological characteristics of the APA, an orthomosaic and digital elevation model were produced, onto which the vectorized geomorphological map was projected. Also, to represent the Maricá plain through time, sea level maps were produced, using satellite images, maps and graphs of sea level oscillations. We gathered this information together to produce a digital resource, with geomorphological information to connect the drone aerial images, maps, and texts, connected with embedded links and animations to show the geomorphology in association with plants and key human features such as roads and habitations of the municipality of Maricá. |
