The term "macroscope" has also been applied to a method or compendium which can view some more specific aspect of global scientific phenomena in its entirety, such as all plant life, specific ecological processes, or all life on earth.Encyclopedia of Life, February 2008

The term has also been used in the humanities, as a generic label for tools which permit an overview of various other forms of "big data". As discussed here, the concept of a "macroscope" differs in essence from that of the

leaves off, covering all objects large enough to be visible to the unaided eye, as well as from macro photography, which is the imaging of specimens at magnifications greater than their original size, and for which a specialised microscope-related instrument known as a "Macroscope" has previously been marketed. For some workers, one or more (planetary scale) "macroscopes" can already be constructed, to access the sum of relevant existing observations, while for others, deficiencies in current sampling regimes and/or data availability point to additional sampling effort and deployment of new methodologies being required before a true "macroscope" view of Earth can be obtained.


History of the concept

The term "macroscope" is generally credited as being introduced into scientific usage by the ecologist
Howard T. Odum Howard Thomas Odum (September 1, 1924 – September 11, 2002), usually cited as H. T. Odum, was an American ecologist. He is known for his pioneering work on ecosystem ecology, and for his provocative proposals for additional laws of thermod ...
in 1971, who employed it, in contrast to the microscope (which shows small objects in great detail), to represent a kind of "detail eliminator" which thus permits a better overview of ecological systems for simplified modelling and, potentially, management (Odum, 1971, figure 10). Some authors, such as Hidefumi Imura, continue to use the term as more-or-less synonymous with an overview or large scale pattern analysis of data in their field.Imura, H., 2013. ''Environmental Systems Studies: A Macroscope for Understanding and Operating Spaceship Earth.'' Springer, 151 pp. (original in Japanese, published 2009)de Magny, G.C., Renaud, F., Durand, P. & Guégan, J.-F., 2008. Health ecology: a new tool, the macroscope. Chapter 8 (pp. 129-148) in Thomas, F., Guégan, J.-F. & Renaud, F. (editors): Ecology and Evolution of Parasitism: Hosts to Ecosystems. Oxford University Press, 240 pp. Other prominent authors and speakers who have utilized "macroscope" terminology for "big picture" views in their particular areas of interest include Jesse H. Ausubel and
John Thackara John Thackara (born 6 August 1951, Newcastle upon Tyne) is a British-born writer, advisor and public speaker. He is known as curator of the celebrated Doors of Perception conference for 20 years, which started in Amsterdam. He is a senior fellow ...
. In actuality, the term (in the present sense of a "larger view" of a subject than can be obtained by any single conventional action) pre-dates its use in Odum's work, being found for example in a book by Philip Bagby entitled "Culture and History: Prolegomena to the Comparative Study of Civilizations" published in 1959, who wrote, " omeone shouldinvent a 'macroscope', an instrument which would ensure that the historian see only the larger aspects of history and blind him to the individual details",Bagby, Philip, 1959. ''Culture and History: Prolegomena to the Comparative Study of Civilizations.'' University of California Press, 244 pp. and also by W.H. Hargreaves and K.H. Blacker, who wrote in 1966 in the journal ''Psychiatric Services'': "The advent of the electronic digital computer is causing a revolution in the behavioral sciences comparable to the impact the microscope had on biology. Like the microscope, the computer provides a view that is beyond the capability of the naked eye. The computer is being used as a "macroscope," which enables us to perceive relationships based on larger patterns of information than we are otherwise able to integrate." Slightly earlier still, in the area of geography, in a 1957 article entitled "Geographer's Quest" for the ''Centennial Review of Arts & Science'', Lawrence M. Sommers and Clarence L. Vinge wrote: "What do we see? What are the inter-relationships that exist among the observed features? The near-views can, by means of mapping, be resolved with over-the-horizon views, and the map becomes a "macroscope" to help us understand the spatial organization of the Earth's phenomena.", while in a 1951 United States Department of Agriculture Appropriation Bill, discussing a recently passed Forestry Management Act, Perry H. Merrill, State Forestor of

, is reported as saying: "Through his ActI feel that we have made a great headway ... instead of looking through a microscope, maybe we can look through a "macroscope", if you want to call it such." The term was (re-)presented as new (Odum's prior use was mentioned in a footnote) by the French scientific thinker
Joël de Rosnay Joël de Rosnay, (born 12 June 1937) is a Mauritius-born French scientific and writer, presently President of Biotics International, a consulting company specialized in the impact of new technologies on industries, and Special Advisor to the P ...
, who wrote a detailed book explaining his concept in 1975: "We need, then, a new instrument. The microscope and the telescope have been valuable in gathering the scientific knowledge of the universe. Now a new tool is needed by all those who would try to understand and direct effectively their action in this world, whether they are responsible for major decisions in politics, in science, and in industry or are ordinary people as we are. I shall call this instrument the macroscope (from macro, great, and skopein, to observe)." In de Rosnay's view, the macroscope could be turned not only on the natural and physical worlds but also on human-related systems such as the growth of cities, economics, and the behaviour of humans in society. More recent workers have tended to use the term synonymously with a whole-of-Earth observational system, or portion thereof, underpinned particularly by satellite imagery derived from

(see below). As an extension of its science context, the term "macroscope" has also been applied in the humanities, as a generic term for any tool permitting an overview of, and insight into "big data" collections in that or related areas. For completeness, it should be mentioned that the concept of a "reverse microscope" is not entirely new: around 80 years earlier, the author
Lewis Carroll Charles Lutwidge Dodgson (; 27 January 1832 – 14 January 1898), better known by his pen name Lewis Carroll, was an English author, poet and mathematician. His most notable works are ''Alice's Adventures in Wonderland'' (1865) and its sequel ...
in the second volume of his novel '' Sylvie and Bruno'', published in 1893, described a fictional professor who includes in his lecture an instrument that will shrink an elephant to the size of a mouse, that he termed the "megaloscope". The Dutch author Kees Boeke also wrote a 1957 book, '' Cosmic View: The Universe in 40 Jumps'', the first portion of which presents images of aspects of the Earth at ever decreasing scales and parallels the subsequent principle of the hypothetical "macroscope" at a series of zoom levels.


Interpretation and practical implementations

The more practical aspect of exactly what constitutes a macroscope has varied through time and according to the interests, requirements, and field of activity of the workers concerned. Sommers and Vinge viewed the "macroscope" as an extended system of mapping to visualize the spatial relationships between items on the surface of the Earth, thus notionally prefiguring the concept of subsequently developed "seamless" geographic display systems via CD-ROMs and the world wide web along the lines of the "Atlas" facility of

. Odum's concept was for the study of ecosystems, by integrating the results of existing methods of surveying, identifying, and classifying their contents, then eliminating fine scale detail to obtain a "big picture" view suitable for analysis and, as needed, simulation. De Rosnay viewed his "macroscope" as a systems-based viewpoint for the study of (among other things) the nature of human society, and understanding of the rationale for human actions. He wrote: From around the early 2000s onwards, interest in the "macroscope" concept has steadily increased, both with the vastly improved computing power in organisations and on scientists' desktops, and with access to more extensive sets of both locally acquired and publicly available data such as Earth observations. For some recent workers such as Dornelas et al. as referenced below, the macroscope is the envisaged set of the observational tools that collectively will deliver the desired synoptic suite of observations over the relevant field of study (in their case for the marine realm, itemised as satellites, drones, camera traps, passive acoustic samplers, biologgers, environmental DNA and human observations), Writing in 2019, these authors stated: For others, the macroscope is already here, as a sort of "virtual instrument", with data sources such as

and data mining—that will permit all existing earth and related observations to be integrated and queried for meaningful results. Writing in 2017 they stated: According to IBM in 2020, these "macroscope" principles were subsequently implemented as an experimental system named the "IBM PAIRS Geoscope",, later re-badged as the Geospatial Analytics component within the IBM Environmental Intelligence Suite and described therein as "a platform specifically designed for massive geospatial-temporal (maps, satellite, weather, drone, IoT "Internet_of_Things".html" ;"title="Internet_of_Things.html" ;"title=""Internet of Things">"Internet of Things"">Internet_of_Things.html" ;"title=""Internet of Things">"Internet of Things" query and analytics services". For Craig Mundey of Microsoft, the benefits of the macroscope are not only for observation of the Earth, but also of aspects of the people on it: Some 10 years later, during which time computing power and readily accessible data storage had continued to advance, Microsoft announced the planned development of its "Planetary Computer", an "approach to computing that is planetary in scale and allows us to query every aspect of environmental and nature-based solutions available in real time." Meanwhile, from around 2010 onwards,

The world is a complex place, and macroscopes help us understand and manage that complexity. They are visual lenses we can use to see patterns and trends in large volumes of data." Another initiative that has been referred to as a "macroscope" is the

(GDELT Project), which monitors (most of) the world's news media creating "trillions of datapoints", then offering "realtime synthesis of global societal-scale behavior into a rich quantitative database allowing realtime monitoring and analytical exploration of those trends." According to the project's website, one of its outputs, the GDELT Global Knowledge Graph (GKG), compiles "a list of every person, organization, company, location and several million themes and thousands of emotions from every news report, using some of the most sophisticated named entity and geocoding algorithms in existence, designed specifically for the noisy and ungrammatical world that is the world's news media." In 2018, 3 partner agencies - The United Nations Development Program (UNDP), the United Nations Environment (UN Environment), and the Secretariat of the Convention on Biological Diversity - launched the "UN Biodiversity Lab" (UNBL) (https://unbiodiversitylab.org/), described as "enhancing access to big data for sustainable development" in the form of global spatial data on protected areas, endangered species, human impact on natural systems, watersheds for key cities, and more. Version 2.0 of the UNBL, released in October 2021, reportedly contains "over 400 spatial data layers across biodiversity, climate change, and development", also offering workspaces where national-level users can upload their own data in order to compile maps for reporting purposes and nation-scale biodiversity planning and monitoring of biodiversity. Some of the differences in approach described above are easier to understand if the macroscope is interpreted as a particular instance of the "value chain of big data" (with a particular focus on earth and/or biosphere observations), which as stated in Chen ''et al.'' (2014) can be divided into four phases, namely data generation, data acquisition (aka data assembly), data storage, and data analysis.Min Chen, Shiwen Mao, Yin Zhang & Victor C.M. Leung, 2014: "Big Data - Related Technologies, Challenges and Future Prospects." Springer Cham Heidelberg New York Dordrecht London, 89 pp. For some workers such as M. Dornelas ''et al.'', the macroscope is the sum of the data collection systems (the generation element) that will provide the content that is needed for subsequent analysis, although some mention is also made of "a series of domain-specific data registries" which would then permit the content to be discovered. For others such as OBIS, the principal effort required to construct the macroscope is the data assembly component, which then permits the integrated analysis of previously disparate datasets (OBIS data can then either be viewed by the tools supplied, or downloaded to a user's own system for additional visualization and analysis); while for facilities interested in discovering patterns in the data (and with sufficient computing power to hand), the macroscope is the suite of temporal and spatial analytical and filtering tools ("lenses" in the terminology of the Indiana University Cyberinfrastructure for Network Science Center) which can be applied once the data are assembled. Since by analogy with the microscope, the macroscope is in essence a method of visualizing subjects too large to be seen completely in a conventional field of view, probably none of these approaches are incorrect, the differences in emphasis being complementary in that each is capable of contributing to the resulting "virtual instrument" that is envisaged by this concept. One trend that is observable, however, is that of increasing base dataset size and desired sampling density, today's "macroscopes" being built upon arrays of fine scale / high resolution data that would have been discarded as undesirable detail (obscuring the "big picture") in the original concepts of Odum and de Rosnay.
