Methods for Creating Cloud Free Satellite Imagery: Sentinel 2

September 7, 2017By Mark AltaweelGIS Data

Nearly 70% of the globe is covered by clouds at any given time. Several methods have been developed to remove cloud cover from satellite imagery.

Understanding Ocean Wave Patterns from Satellite Imagery of Sun Glitter

March 21, 2017By Caitlin DempseySpatial Analysis

Researchers have developed a method by which to translate satellite imagery of sun glitter on the water into data about the direction, height and movement of waves.

Acquired on 27 June 2015 at 10:25 UTC (12:25 CEST), just four days after launch, this close-up of France’s southern coast from Nice airport (lower left) to Menton (upper right) is a subset from the first image from the Sentinel-2A satellite. This false colour image was processed including the instrument’s high-resolution infrared spectral channel. Source: Copernicus data (2015)/ESA

First Satellite Images from Sentinel-2 Delivered

June 29, 2015By Caitlin DempseyGIS Data

Four days after its launch, the first images from Sentinel-2 have been delivered. Covering an area from central Europe and the Mediterranean, ending in Algeria, images from the satellite is part of the Copernicus environmental monitoring program. Designed as a twin satellite system, Sentinel-2A and Sentinel-2b (which will launch in 2016) will provide […]

Mapping Tree Species in Amazonia Using Satellite Imagery and Machine Learning

Researchers at the University of Turku have a developed a method of modeling tree species distribution in Peruvian lowland Amazonia using satellite imagery and machine learning techniques in order to produce higher resolution habitat suitability maps.

Detecting Storm Intensity from Satellite Imagery Using Machine Learning

The Deep Learning-based Hurricane Intensity Estimator is an experimental portal that uses machine learning techniques to analyze spatial patterns in infrared satellite imagery in order to predict tropical cyclone intensity.

Elements of a Map

Maps are the primary tools by which spatial relationships are visualized. Maps therefore become important documents. There are several key elements that should be included each time a map is created in order to aid the viewer in understanding the communications of that map and to document the source of […]
