Up to 1879 the 1:2500 maps were accompanied by Books of Reference or "area books" that gave acreages and land-use information for land-parcel numbers. After 1879, land-use information was dropped from these area books; after the mid-1880s, the books themselves were dropped and acreages were printed instead on the maps. [ 2 ]
The map browsing interface, showing thumbnail photos for each completed "geograph". Geograph Britain and Ireland is a web-based project, begun in March 2005, to create a freely accessible archive of geographically located photographs of Great Britain and Ireland. [1]
This is a list of the 296 districts of England ordered by area, according to Standard Area Measurements published by the Office for National Statistics. [1] The area is defined as 'area to mean high water excluding inland water'. [2]
A properly designed and installed extensive green-roof system can cost $108–$248/m 2 ($10–$23/sq ft) while an intensive green roof costs $355–$2,368/m 2 ($33–$220/sq ft) However, since most of the materials used to build the green roof can be salvaged, it is estimated that the cost of replacing a green roof is generally one third of the ...
the definition follows a ‘bricks and mortar’ approach, with areas defined as built-up land with a minimum area of 20 hectares (200,000 m 2), while settlements within 200 metres of each other are linked. Built-up area sub-divisions are also identified to provide greater detail in the data, especially in the larger conurbations. [1]
It has been suggested that to stabilize Earth's energy budget and thus cease warming, 1–2% of the Earth's surface (area equivalent to over half of Sahara) would need to be covered with these emitters, at the deployment cost of $1.25–2.5 trillion. While low next to the estimated $20 trillion saved by limiting the warming to 1.5 °C (2.7 °F ...
In the following years the cost of photovoltaic (PV) panels fell, [1] and the FIT rates for new installations were reduced in stages until the scheme closed to new applications in 2019. [2] As of 2023, over 14.4 gigawatt (GW) had been installed, a third of which was rooftop solar. [3]
The load of approximately 250 kg per m 2 of a sod roof is an advantage because it helps to compress the logs and make the walls more draught-proof. In winter the total load may well increase to 400 or 500 kg per m 2 because of snow. [1] Sod is also a reasonably efficient insulator in a cold climate.
