Journal Impact Factor 2017 Released

The Journal Impact Factors of 2017, based on the Journal Citation Reports 2016 (JCR), have been released by Clarivate Analytics. You can check it on Web of Science.

I sorted out some journals related to Remote Sensing, Geography, Hydrology, and Wetlands. You can download my sorted list HERE. Note that this is only my personal classification. My apologies if some of your preferred journals are not on the list here.

Keep in mind that journal impact factor is just one metrics, so don’t take it too seriously!

NASA and Japan make ASTER imagery available for free

Source: http://goo.gl/f9ECIG

The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of the instruments on NASA’s Terra satellite. Although it is a NASA satellite, the instrument belongs to Japan’s Ministry of Economy, Trade and Industry (METI). The instrument was launched in 1999 and has captured more than 2.95 million individual scenes since then. On the first of April this year NASA announced that the full catalogue of imagery is being made available to the public at no cost. The instrument, amongst other things, takes stereoscopic images that enables it to calculate altitudes albeit rather low resolution. The elevation data has always been available to the public at no cost.

The most interesting images have been collected in a gallery found here. You can also see some of the more interesting images in this article and this one.


Mt. Etna, when it erupted in July 2001. The full resolution image and description can be found here.


This image shows the 3D capabilities of ASTER. The full resolution image and description can be found here.

To access the full database of imagery, you can use the MADAS (METI AIST Data Archive System). A really nice feature is that it allows you to download the images as network-linked KML files.

The imagery has a similar resolution to Landsat imagery (approximately 30 m per pixel), so is really only suitable for viewing large scale phenomena. As with Landsat imagery its best use would be to see current events before other satellite imagery becomes available. In December last year we used Landsat imagery to look at the scar made by a tornado near Holly Springs, Mississippi. We found it relatively easy to find an ASTER image of the same region captured on March 28th, 2016, and the scar is still visible. Download this KML file to view it in Google Earth.


The image only covers a small part of the tornado’s track.

How to Download Sentinel Satellite Data for Free

For those who are interested in using the Sentinel-1 and Sentinel-2 Satellite Data from the European Space Agency’s Copernicus Programme, please check out this blog at http://gisgeography.com/how-to-download-sentinel-satellite-data/. Note that Sentinel 2A multispectral data has a 10-m spatial resolution, which is much better than the Landsat 8 with 30-m resolution.

What are the Spectral Bands of Sentinel 2A and 2B?

The spectral and spatial resolution of Sentinel 2A are listed below. There are 13 bands in total. Four spectral bands have a 10 meter resolution. Six bands have a 20 meter resolution. And the remaining 3 have a spatial resolution of 60 meters.

Here are the spectral band details for Sentinel 2A:

Source: SENTINEL-2 Spatial Resolution

Each single satellite revisit time is 10 days. Because there are two satellites (Sentinel 2A and 2B), this means it has a combined constellation revisit of 5 days.

New ESA satellite – Sentinel-2A delivers first images

The new ESA satellite – Sentinel-2A was successfully launched on 23 June, 2015.  See below for the key facts of the satellite.  The first few images obtained by the satellite have been released.  The data will be freely available to the public later this year. Stay tune!

Orbit: Polar, Sun-synchronous at altitude of 786 km

Revisit time: Five days from two-satellite constellation (at equator)

Coverage: Systematic coverage of land and coastal areas between 84°N and 56°S

Instrument: Multispectral imager (MSI) covering 13 spectral bands (443 nm–2190 nm) with a swath width of 290 km and spatial resolutions of 10 m (4 visible and near-infrared bands), 20 m (6 red-edge/shortwave-infrared bands) and 60 m (3 atmospheric correction bands)

The imager’s 13 spectral bands, from the visible and the near infrared to the shortwave infrared at different spatial resolutions, take land monitoring to an unprecedented level. In fact, Sentinel-2 is the first optical Earth observation mission of its kind to include three bands in the ‘red edge’, which provide key information on the state of vegetation.

The spacecraft will also be readied to start the routine acquisition of high-resolution images of Earth’s land surfaces, large islands, inland and coastal waters on a ten-day revisit cycle, which will drop to five days when the constellation with the Sentinel-2B satellite is implemented in 2016.

2015 Journal Impact Factor Released

The 2015 Journal Impact Factor has been released. You can download the complete list here.

I sorted out some journals related to Remote Sensing, Geography, and  Hydrology. You can download my sorted list here.

It appears that the impact factors of several remote sensing journals have increased from 2.x to 3.x, such as International Journal of Applied Earth Observation and Geoinformation, Remote Sensing.  Note that this journal impact factor ranking is slightly different from the Google Scholar Journal Ranking.

Keep in mind that journal impact factor is just one metrics, so don’t take it too seriously!

Asia & Australia SRTM 30 m Available

The void-free 1 arc second (~ 30 meters) SRTM data for Asia and Australia are available now. See below for an index map of the newly available full-resolution data. The new data are available for download from the USGS EROS Data Center.

See an ESRI blog below for more details:

Asia & Australia SRTM 30 m in Esri World Elevation Services

Esri World Elevation Layers  are enhanced with more detailed void-free 1 arc second (~ 30 meters) SRTM data for Asia and Australia. The Australian DEM (DEM-S), which is a cleaned and smoothed version of SRTM 1 arc sec, is courtesy of Geoscience Australia, while the Asia data is acquired from NASA. With this update, there is now 3 times more detail in these areas.

Mount Everest – the highest peak in Himalayas and World at 8,848 m (29,029 ft) above sea level (SRTM 90 m vs SRTM 30 m)

Eravikulam National Park, Western Ghats, Kerala, India. Western Ghats mountain range is UNESCO World Heritage Site and is one of the eight “hottest hotspots” of biological diversity in the world (SRTM 90 m vs SRTM 30 m)

Mount Fuji, Japan – an active stratovolcano and the highest mountain in Japan at an elevation of 3,776.24 m (12,389 ft) above sea level (SRTM 90 m vs SRTM 30 m)

Mount Bogong, Australia – is part of the Victorian Alps of the Great Dividing Range and the highest mountain in Victoria, Australia, at 1,986 meters (6,516 ft) above sea level (SRTM 90 m vs SRTM 30 m)

Our dynamic world elevation image services (Terrain and TopoBathy) are not just for visualization (such as multi-directional hillshade,tinted hillshade) but provide access to raw elevation values and derivatives (such as slope, aspect) for analysis. Access to these global layers is free and does not consume any credits; all you need is an ArcGIS Organizational account. It’s that easy!

With this update and previously released Africa , South America & Western Europe, SRTM 1 arc second is now available for the most part of the world from N 60 to S 60 as depicted below:

SRTM 1 arc second (~30 meter) covers land areas between 60 degrees north and 56 degrees south

Elevation Analysis Services are also updated to consume SRTM 1 arc second for Profile, Viewshed and Summarize Elevation tasks. SRTM updates are also rolled out in Terrain 3D service powering Web Scene viewer and ArcGIS Pro Scene.

For more information about the coverage of the World Elevation services please check out our Elevation coverage map.

USDA released 4-Band NAIP Imagery

USDA finally starts publicly distributing the 4-band NAIP imagery in addition to the natural color imagery.  To access NAIP Public facing data, use the following URL in ArcGIS: http://gis.apfo.usda.gov/arcgis/services.  Instructions can be found on the APFO website at: http://www.fsa.usda.gov/Internet/FSA_File/2013_apfo_webservice_10x.pdf.  By adding “rest” to the link you can apparently get more options:   http://gis.apfo.usda.gov/arcgis/rest/services
