Combining Satellite and Weather Data for Crop Type Mapping: An Inverse Modelling Approach

no code implementations29 Jan 2024 Praveen Ravirathinam, Rahul Ghosh, Ankush Khandelwal, Xiaowei Jia, David Mulla, Vipin Kumar

We finally discuss the impact of weather by correlating our results with crop phenology to show that WSTATT is able to capture physical properties of crop growth.

Priority-Flood: An Optimal Depression-Filling and Watershed-Labeling Algorithm for Digital Elevation Models

2 code implementations13 Nov 2015 Richard Barnes, Clarence Lehman, David Mulla

It is shown that by using a plain queue to fill depressions once they have been found, an O(m lg m) time-complexity can be achieved, where m does not exceed the number of cells n. This is the lowest time complexity of any known floating-point depression-filling algorithm.

An Efficient Assignment of Drainage Direction Over Flat Surfaces in Raster Digital Elevation Models

1 code implementation13 Nov 2015 Richard Barnes, Clarence Lehman, David Mulla

In testing, the improved algorithm ran 6. 5 times faster than the old for a 100 x 100 cell flat and 69 times faster for a 700 x 700 cell flat.
