It is made from 33 cloud-free annual mosaics, one for each year from 1984 to 2016, which are made interactively explorable by Carnegie Mellon University CREATE Lab's Time Machine library, a technology for creating and viewing zoomable and pannable timelapses over space and time.

Using Earth Engine, we combined over 5 million satellite images acquired over the past three decades by 5 different satellites. The majority of the images come from Landsat, a joint USGS/NASA Earth observation program that has observed the Earth since the 1970s.

Photographer Quintin Lake is walking 10,000km around the edge of Britain, capturing the ‘surprises, beauty and strangeness’ of our coastline.

My Walk of Life with Quintin Lake

Interview by Matthew Jones I am walking and photographing the entirety of the British coastline. The project is called The Perimeter and I envisage it will take five years to complete. There is nothing as profound as the experience of a landscape on foot. You meet people and discover little things that you wouldn’t notice if you were moving faster. I’m walking from dawn to dusk, carrying all my kit and mostly wild camping. I started at St Paul’s Cathedral, because it is iconic and symbolically it felt like the centre of London. I take about 400 photographs per day. My focus is on lesser-known stretches of coastline rather than well-known landmarks. The walking is difficult. The Isle of Grain in north Kent is particularly strange and remote. Ast Lines. Coasts are a more complex geographical entity than you might believe.

Benjamin Hennig maps the world's coasts to learn more The question about the length of the world’s coastlines is not as easy to answer as it would initially seem. The British mathematician and meteorologist Lewis Fry Richardson was among the first to investigate this phenomenon of the fractal nature of boundary lines in the early twentieth century.

The rougher coastlines are, the more of a fractal nature they have and the more difficult it becomes to determine their length since this changes when looking at it using different scales and resolutions. Richardson’s fellow mathematician, Benoit Mandelbrot, further investigated this phenomenon by looking at the length of the coast of Britain. Education pack worksheets.

Green Infrastructure Mapping Guide

This online guide shows spatial analysts how to incorporate nature-based solutions, or green infrastructure, into their GIS work. A GIS work plan is provided, along with examples, process guidance, case studies, and templates. This Guide Features A step-by-step process. What is a living shoreline? Living shorelines are a green infrastructure technique using native vegetation alone or in combination with offshore sills to stabilize the shoreline.

What is a living shoreline?

Living shorelines provide a natural alternative to ‘hard’ shoreline stabilization methods like stone sills or bulkheads, and provide numerous benefits including nutrient pollution remediation, essential fish habitat provision, and buffering of shoreline from waves and storms. Living shorelines are known to store carbon (known as carbon sequestration), which keeps carbon out of the atmosphere. Continued use of this approach to coastal resilience will result in increased carbon sequestration and storage, potentially mitigating the effects of climate change. Living Shorelines Support Resilient Communities Living shorelines use plants or other natural elements—sometimes in combination with harder shoreline structures—to stabilize estuarine coasts, bays, and tributaries.
