Location Profile Reports on Climate Warming Trends

November 3rd, 2016|Australia, Climate Change, Property Information|

As part of new asset / property location information, we are making reports on location-specific climate warming trend. It is based on the analysis of the new NASA Earth Exchange Global Daily Downscaled Projections dataset (NEX-GDDP, 2015), which is derived from the runs of 21 advanced Global Climate Models under two greenhouse gas emissions scenarios [...]

BigData Earth Releases Geocoding DoubleCheck – A Unique Location Accuracy Assessment Tool for the U.S. Parcel-level Geocoding

August 23rd, 2016|Geocoding, Image Analysis, Land parcel, Property Information, USA|

23 August 2016: Geocoding location accuracy is fundamental to the exploration of location-centric business intelligence and important for applications such as asset management and risk analysis. Currently very few assessment tools on this exist. Without the confidence on the location accuracy, subsequent analytics and results would be seriously compromised. BigData Earth is pleased to release a new product called Geocoding [...]

Observing the May 2016 Fort McMurray Wildfire: A Survey of Satellite Imagery Sources (including Sentinel-2)

May 27th, 2016|Canada, Earth Observation, Image Analysis, Landsat, Major Events, Sentinel-2, Wildfire|

The May 2016 Fort McMurray Wildfire in Alberta, Canada is catastrophic. The fire started on May 1, and as of May 24, is still raging. The fire has destroyed ~2,400 homes and buildings, and resulted in massive fire scars (burnt areas) over 500,000 hectares. It becomes the most expensive nature disaster in Canadian history, with an [...]

Innovative Earth Observation Image Analysis for Wildfires and Flooding: Two U.S. Examples

April 1st, 2016|Bushfire, Earth Observation, Flood, Image Analysis, Landsat, Major Events, USA, Wildfire|

Modern Earth Observation satellites are often equipped with special sensors that are capable of measuring the reflectance of ground features at short-wave infrared (SWIR) wavelengths. Most SWIR images currently in use are from the following four major satellites: Sentinel-2 (ESA, 20m resolution for SWIR bands) Landsat-8 and Landsat-7 (NASA & USGS, 30m resolution for SWIR bands) ASTER [...]

Major Bushfires in Australia in 2015-2016 Summer: Before and After Satellite Imagery

March 8th, 2016|Australia, Bushfire, Climate Change, Earth Observation, Image Analysis, Landsat, Major Events, Wildfire|

8 March 2016 (We thank the Australian Broadcasting Corporation - ABC - for promoting this for the general public. Twitter, ABC website) Extreme temperatures, frequent heatwaves and prolonged drought (link), enhanced by one of the most powerful El Niño events, have once again caused many bushfires in Australia in 2015-2016 summer season. Major damaging bushfires (grass fires and forest fires) [...]

The Warming Trend across Australia in 2100

March 5th, 2016|Australia, Climate Change|

Statements on the warming climate are supported by two main research approaches: observation and modelling. Observation: It has long been diagnosed that the Earth has a fever, and some latest measurements and facts are alarming: 2015 was the hottest on record globally; January 2016 was the hottest month on record globally (link); February 2016 had record warmth in [...]

Releasing 30m-resolution, Large-sized Global Elevation Mosaic and Shaded-relief Basemaps

March 3rd, 2016|Elevation|

Terrain data are extremely useful and essential for a wide range of environmental studies. At the local level, high-density LiDAR point clouds and derived high-resolution (e.g. 1m) Digital Elevation Models (DEMs) are increasingly produced. At the global level, medium-resolution (30m) open elevation data (e.g. SRTM and ASTER GDEM) are popular in the scientific community. The quality [...]
