Remote sensing offers robust tools for habitat mapping and assessment; however, achieving policy-relevant monitoring requires parallel development of high-quality field data and drone-based methods for data collection and validation.<\/p>\n\n\n\n<p><strong>The main aim of this PhD research is to develop a multisource-data approach for canopy composition characterization and habitat mapping.<\/strong> The study will utilize drone-based data, airborne and Satellite data. The doctoral researcher will conduct research in close cooperation with Digital Geosciences Research Group as well as collaborators School of Forest Sciences and Finnish environment institute (SYKE). Geographically study will focus on boreal &nbsp;forests and mountain birch forests close to the rapidly changing northern treeline. Work will focus on biodiversity indicators eg. &nbsp;deadwood (standing-downed), certain tree species like European aspen (<em>Populus tremula<\/em>) and goat willow (<em>Salix Caprea<\/em>). Another aim is comparison of canopy dynamics of mountain birch forests and Northern boreal forests using LAI and ALS data.<\/p>\n\n\n\n<p>Mapping and characterizing deadwood and delineating ecologically significant habitat types in boreal forests using optical drone imagery and dense LiDAR point clouds will be in focus. Study will use dense LiDAR data (National Land Survey), optical airborne and satellite data. Validation data will be provided by SYKE, validation data: sampling includes ecologically significant habitats 10-20 sites 2026 and selected drone data from sites.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Academic background and skills of the applicant<\/h2>\n\n\n\n<p>An ideal candidate holds <strong>a master\u2019s degree in geography, forestry, ecology, environmental science, geoinformatics, computer science, or a closely related field. <\/strong>The candidate is expected to have a strong interest in forests, biodiversity, and remote sensing, as well as a commitment to high-quality research. An interdisciplinary or multidisciplinary research mindset is highly valued. Familiarity with multiscale and multisource Earth observation data and products, such as field, UAV, airborne, and spaceborne sensor data, is expected. Solid programming skills in R or Python are required.<\/p>\n\n\n\n<p>The successful candidate demonstrates a proactive and collaborative attitude, enjoys working as part of a team, and is motivated to engage with land management actors and other relevant stakeholders. Experience in research dissemination and\/or application-oriented activities is considered an advantage. The ability and willingness to undertake research periods with national and international partners are also regarded as advantageous.
