The coastal area of Special Region of Yogyakarta (DIY) will experience rapid regional development after the functioning of the Southern Cross Roadway (JJLS) and New Yogyakarta International Airport (NYIA). In order to increase Regional Original Income (PAD) from the tourism sector, these developments must be welcomed with developments in the field of coastal tourism, especially in the form of ecotourism. The process of developing mangrove ecosystems for ecotourism in DIY must be synchronized with applicable government policies, especially policies that regulate spatial planning and development policies in the tourism sector. This study aims to analyze the existing conditions of mangrove ecosystems in the coastal areas of the Special Region of Yogyakarta. Mangrove mapping was carried out in four different locations, namely at Baros Beach, Kretek, Bantul Regency and Jangkaran Mangrove Forest Area, Kulonprogo Regency. Fieldwork consists of small format aerial photo data acquisition, Ground Control Point (GCP) and Independent Check Point (ICP) collection using Geodetic GPS, along with observations of mangrove conditions in the field. Post-field stages consist of various types of processes regarding processing field data and analysis, including orthophoto mosaics, accuracy calculations, and acquisitions of mangrove information such as area and distribution. The main benefit of this research is the availability of basic data on the existing conditions of mangrove areas in the Special Province of Yogyakarta. This basic data will then be used as a reference for managing the coastal environment and improving the economic conditions of the community through the development of mangrove ecotourism-based tourism. it also supports disaster risk reduction efforts through the development of mangrove ecosystems.

Mangrove ecosystem is one of coastal resources that have many benefits for coastal communities. The mangrove ecosystem has very high economic and ecological functions if it is developed and preserved properly. Nowadays, many mangrove ecosystems are threatened by human activities. It is necessary to preserve and to develop the mangrove ecosystems to avoid the impact of human activity and to increase their usefulness. In the process of developing the mangrove ecosystems, detailed data are required to provide a comprehensive overview of the environmental and physical conditions of the mangrove ecosystems. The study aims at identifying and making the inventory of the existing condition of the mangrove ecosystems related to mangrove cover and biodiversity. The data are collected using aerial photography and UAVs, observation and field measurement. The data inventory making is the first step in the process of developing and preserving the mangrove ecosystems. It finds that the use of the UAVs for the mangrove ecosystem data inventory making can give high accuracy data. The mangrove cover can easily be identified using image segmentation or onscreen digitization analysis. Finally, the UAVs can be a promising technology in the management and the monitoring of the mangrove ecosystems.
