UAV‐Based Precision Seed Dropping for Automated Reforestation
Journal of Field Robotics, EarlyView.ABSTRACT Wildfires and deforestation pose significant threats to forest ecosystems, motivating scalable methods for reforestation beyond labor‐intensive cultivation of native forest seedlings in nurseries. To enable large‐scale direct seeding of native species, this paper presents the design, analysis, and field evaluation of a UAV‐based seed‐dropping ...

Analysis of DEM combination methods using high resolution optical stereo imagery and interferometric SAR data [PDF]
, 2009 Digital elevation models (DEM) from satellite data are generated mainly from two types of datasets using completely different methods: photogrammetry for optical stereo images (e.g.

Vulnerability to Dams of the Last Undammed Large Rivers of Southeast Asia
River Research and Applications, EarlyView.ABSTRACT The vast majority of large Eurasian rivers are regulated by hydropower dams, but some have survived as free‐flowing rivers so far in the Arctic and along stretches of the Myanmar coast. There, the Ayeyarwady (Irrawaddy) and Salween Rivers, two of the largest rivers of Southeast Asia, provide a huge amount of sediment, nurturing floodplains and

SRTM Slope DEM for Great Britain
, 2017 This SRTM Slope Map was created from level 1 SRTM NASA data which was cleaned and had holes patched. The slope map was created in ArcMap (presumably using the simple 3x3 nearest neighbour method).

Remote Sensing in Ecology and Conservation, EarlyView.Brazil's Cerrado valley wetlands—swamp savanna and gallery forest—are highly important for the biome's water cycle and carbon storage and are susceptible to degradation from the impacts of land use expansion and the climate crisis. In support of their detailed monitoring and assessment, we developed and tested a transferable mapping approach that ...

Improved land cover mapping using aerial photographs and satellite images
Open Geosciences, 2014 Manual Land Cover Mapping using aerial photographs provides sufficient level of resolution for detailed vegetation or land cover maps. However, in some cases it is not possible to achieve the desired information over large areas, for example from ...

River, EarlyView.Abstract The Ajay River, originating from the Chotanagpur Plateau (Bihar) and flowing through Jharkhand into West Bengal before merging with the Bhagirathi‐Hugli near Katwa, is among the most flood‐prone rivers in the region. Its lower reaches frequently experience rainfall‐induced flooding and embankment breaches during the mid‐ to late‐monsoon season.

Hungarian Geographical Bulletin, 2014 The availability of global coverage digital surface models (like ASTER GDEM or SRTM) and the variation of fused models based on these (like EU-DEM) still has a great impact on scientific researches, as they provides a fairly good base dataset with a low ...
