Coursera's free R courses are running again soon
If you use R, or are thinking that you might want to, then you should check out the Coursera's free R courses. Coursera have already run a couple of R courses which are available on YouTube and are linked to from the Revolutionanalytics website.
They are pretty full on courses, but should help you get to grips with R. If you want to participate in the full Coursera experience with paced online lectures, quizzes, data analysis assignments, and interaction with more than 100,000 fellow students, the courses will be running again soon. Computing for Data Analysis starts again on September 23 and runs for 4 weeks; Data Analysis starts on October 28 and runs for 8 weeks. Follow the link below for introductory videos for each course, and links to register at Coursera.
Computing for Data Analysis
NASA Earth Observations website updated
NASA have updated their Earth Observations (NEO) website making it easier to download datasets. data is organised into themes such as Atmosphere, Energy, Land and Ocean.
From the NEO website "Our mission is to help you picture climate and environmental changes as they occur on our home planet. Here you can browse and download imagery of satellite data from NASA's constellation of Earth Observing System satellites. Over 50 different global datasets are represented with daily, weekly, and monthly snapshots, and images are available in a variety of formats including JPEG, PNG, Google Earth, and GeoTIFF."
All images and data in NEO are freely available for public use without further permission. Please use the credit statement attached to each dataset, or at the very least credit NASA Earth Observations as the source.
geojson.io - create, edit share geojson without the hassle
Spotted on SlashGeo, there is a great new way of creating and sharing basic vector geodata on a map. geojson.io allows users to draw features on a basemap, or upload their own geospatial data then edit it and share it with others. The interface is simple and intuitive. Use geojson.io with modern mapping tools, like TileMill, MapBox.js, GitHub, and Shapely. It’s made of open source: Leaflet.draw, MapBox.js, CodeMirror, and a new library from the same author, geojsonhint, that does GeoJSON validation. All very neat and certainly worth 15 minutes investigation over coffee.Date September 10, 2013
Huge shield volcano discovered in Pacific
Spotted on the BBC website, a team of scientists have used remote sensing to discover an immense shield volcano in the northwest Pacific. The team, led by William Sager of the Department of Oceanography at Texas A&M University, used a range of remote sensing techniques to map the structure. Multi-Channel Seismics (MCS) were used to collect data across the Shatsky Rise using a 6 Km, 480-channel array and 36-airgun array. This is huge and helps to provide deep penetration into the igneous crust and the team have transects that cross the entire oceanic plateau. The team have been able to interpret grabens, calderas and other secondary volcanic structures which sit on the main dome.
By analysing the data the team suggest that the Tamu Massif is one enormous shield volcano measuring 450km by 650km. It is larger than Olympic Mons on Mars, the largest volcanic structure we have discovered to date in the solar system. But don’t worry, the team say there is very little chance that the volcano would ever erupt.
The paper is available in Nature Geoscience.
Proceedings of the 26th International Cartographic Conference
The proceedings of the International Cartographic Conference 2013 are now online. So if you didn't manage to make it along to Dresden then you can browse through the archive and read the papers that were presented.Date September 9, 2013
New OS County Map Records available for England and Wales from NLS
The National Library of Scotland (NLS) has just completed a project to list all our holdings of Ordnance Survey six-inch and 25 inch to the mile County Series maps of England and Wales - 152,332 records in total.
The results are newly available in our OS sheet records viewer:
This viewer provides clickable indexes for OS County Series maps at 1:2,500 and 1:10,560 that were published for anywhere in the United Kingdom from 1841-1952. This includes all the editions of map sheets at these scales, providing a geographic portal for discovering when large-scale OS maps were surveyed, revised and published for any particular area. The viewer also includes sheetlines of National Grid maps at 1:10,000 and larger scales for England and Wales, but currently only specific dates of these National Grid maps for Scotland.
The NLS do an amazing job of making old maps available onine for free. This project was part funded by EDINA .
Research Ecologist - Population Modelling
Certainly some GIS required for the modelling job listed by the British Trust for Ornithology. The British Trust for Ornithology is seeking applications for three Research Ecologists. One post will be in the Land-Use Research Team and will undertake research in terrestrial ecology, considering birds and other biodiversity, with particular focus on farmland and woodland. The second will be in the Population Ecology and Modelling Team and will seek to understand drivers of change of bird populations and what they tell us about wider environmental change, as well as working on climate change projects. The third post is designed to ease current work pressures in the organisation. The focus will depend on the interests and abilities of the scientist appointed and the work available.
These are full-time posts for two years in the first instance. Candidates should have a PhD in ecology or other related area, or equivalent experience. They will have excellent computing skills, analytical skills and ecological knowledge. Experience in field ecology, biodiversity monitoring, relevant data analysis (e.g. of long-term data sets) or work relating to climate change, international fieldwork, eco-system services and migration analysis would be an advantage for one or more of the posts.
Closing date for receipt of applications is 9am on Monday 16 September 2013.
Salary: £21,700 - £24,111 + pension
Closing Date: 9am on Monday 16 September 2013.
First ICA-OSGeo Lab in Switzerland established at SUPSI
OSGeo are pleased to announce that the first Open Source Geospatial Lab in Switzerland is established at the University of Applied Sciences and Arts of Southern Switzerland (SUPSI).
This open source geospatial laboratory is a joint initiative of the International Cartographic Association (ICA) and the Open Source Geospatial Foundation (OSGeo). The lab will be led by Professor
Massimiliano Cannata. He also leads the Division of Geomatics
OSGeo is a not-for-profit organisation founded in 2006 whose mission is
to support and promote the collaborative development of open source
geospatial technologies and data.
ICA is the world authoritative body for cartography, the discipline
dealing with the conception, production, dissemination and study of
OS at the 26th Cartographic Conference
The 26th Cartographic Conference was held in Dresden, Germany. This probably the biggest cartographic event of the year and it showcases the new innovations in cartography. The OS have written a nice blog post summarising what they presented at the event. This is great, as I am sure it will prove interesting to those who could not attend. Papers and poster are available as PDF documents.Date September 6, 2013
Thousands of archived Landsat images now available
Thousands of images from the US Landsat satellites acquired over 30 years have been released for the first time for online access. In addition, the newest data over Europe from the latest satellite in the series, Landsat 8, are now accessible in near-real time through the European Space Agency's (ESA) new portal.
About 150 000 new products from the Landsat 5 satellite are available for direct download, free of charge. The products from the satellite’s Thematic Mapper instrument were acquired by the Kiruna ground station in northern Sweden between 1983 and 2011.
ESA recently completed reprocessing the data at a higher quality than ever before. The products are now aligned with those from the Landsat 8 satellite, paving the way for ESA’s provision of data from the latest satellite in the series.
The next phase of Landsat archive processing will include the rest of ESA’s unique data holdings, including all Thematic Mapper data acquired by the Matera (Italy) and Maspalomas (Canary Islands, Spain) stations.
Data from the Enhanced Thematic Mapper on Landsat 7 and the Multispectral Scanner on the first five Landsat missions, dating back more than 40 years, will also be processed. These products will gradually become available over the course of 2014.
At least half a million new, high quality data products are expected from this overall endeavour. The project was funded by ESA’s Earthnet programme, which has supported access to non-ESA missions for more than 30 years.
