Autor: R. Fernandes, C. Prevost, F. Canisius, S. G. Leblanc, M. Maloley, S. Oakes, K. Holman, A. Knudby

Publikováno v: The Cryosphere, Vol 12, Pp 3535-3550 (2018)

Differencing of digital surface models derived from structure from motion (SfM) processing of airborne imagery has been used to produce snow depth (SD) maps with between ∼ 2 and ∼ 15 cm horizontal resolution and accuracies of ±10 cm over

Analysis of seasonal land use in Usangu wetlands, Tanzania: an object-oriented technique for multi-temporal analysis with high-resolution data

Autor: Hugh Turral, B. P. Mbilinyi, F. Canisius

Publikováno v: International Journal of Remote Sensing. 32:1885-1900

A multi-temporal analysis of Landsat panchromatic data was applied to the Usanga wetlands in Tanzania, where there are concerns that irrigated agricultural development is reducing downstream water availability. As there are many small fields, and eve

Updating geomorphic features of watersheds and their boundaries in hazardous areas using satellite synthetic aperture radar

Autor: F. Canisius, Mitsuharu Tokunaga, Kiyoshi Honda

Publikováno v: International Journal of Remote Sensing. 30:5919-5933

Volcanic disasters can cause severe loss of human life and damage to property. The main damage is caused during an eruption and from subsequent erosion of deposited materials. Heavy rainfall in volcanic areas erodes volcanic deposits, mainly pyroclas

Fourier analysis of historical NOAA time series data to estimate bimodal agriculture

Autor: David Molden, Hugh Turral, F. Canisius

Publikováno v: International Journal of Remote Sensing. 28:5503-5522

In the present study, NDVI time-series 10-day composites derived from NOAA AVHRR data were used to estimate bimodal agriculture areas (where there are two seasons of cultivation per annum) using Fourier approach. The NDVI sequence was transformed int
