The ACRS Proceedings, Year by Year

Since 1980, every Asian Conference on Remote Sensing has left behind a proceedings volume, and the accumulated stack, thousands of papers across four decades, has become one of the primary records of how satellite mapping actually developed in Asia. Journals publish the polished results; the proceedings publish the process, the methods as first attempted, the country reports as first delivered, the instruments as first tested. This guide explains how the archive is organised, what it is genuinely good for, and how to search it without drowning, written for readers who arrive from an old link as much as for fresh researchers.

What the volumes contain

A typical edition's proceedings hold a few hundred items: full papers from the technical sessions, extended abstracts, invited overviews and the national reports several delegations deliver annually. The subjects track the conference themes of each era, and reading across the decades is watching the field change underfoot. The early volumes argue about receiving stations, film products and the first classified land-cover maps of provinces; the middle years bring digital classification, geographic information systems and the arrival of national satellites, the fleets surveyed in the guide to Asia's own Earth observation satellites; the recent volumes are dense with radar time series, machine learning and cloud platforms, the tools compared in the guide to Google Earth Engine and QGIS. No curator planned the collection as a history; the annual ritual simply produced one.

From printed pages to files

The archive's format tells its own story of the field's technology. The earliest editions were printed volumes, photographed and typeset, circulated to libraries and member institutions. Compact discs took over in the 1990s, then online repositories, with individual papers posted as files under web addresses that themselves became part of the record. Those addresses have not been stable forever: hosting moved as associations and servers reorganised, and some of the older repositories went dark or changed shape, which is why readers so often reach this magazine through links that once pointed at a proceedings paper. For the papers themselves, the durable paths are the association's current channels, described in the guide to the ACRS conference, and the library copies held by universities across the region, many of them catalogued and requestable.

What the archive is good for

Four uses account for most serious visits. Method ancestry: a technique presented as novel this decade often has an ancestor in a 1990s volume, stated in plainer language, and citing the ancestor is both honest and useful. Historical baselines: land-cover maps, city footprints and crop estimates made decades ago serve as the starting point for change studies, the long comparisons behind the guides to rice paddies seen from orbit and how Asian megacities grow. Country chronicles: the national reports, delivered year after year, form an almost continuous record of what each space programme intended, launched and admitted, unfiltered by the rewriting that final histories receive. And teaching material: an old paper that explains a method with the enthusiasm of first contact often communicates it better to a student than the mature textbook treatment. Researchers with time constraints should begin with the session overviews and national reports of the editions that bracket their question.

How to search it without drowning

Practical advice for a first dig. Start from the year, not the keyword, because the conference's own theme of each edition narrows the search more than any query does, and the volume titles record those themes. Read the table of contents of a whole edition rather than hunting individual papers; the structure shows which sessions the community considered central that year. Follow citation chains backward from a current paper, since a modern reference to an ACRS paper is a vote that the older work is findable and worth the trip. When a link fails, as links to two-decade-old repositories do, the recovery sequence is library catalogues, the association's current site, and the Internet Archive's stored copies of the old pages, in that order of reliability. And when a paper matters, save the file that day, because online proceedings addresses are perishable in a way library shelves are not, an irony the field has lived through more than once.

A note to readers arriving from old addresses

Some visitors will reach this page through links that once served the association's proceedings directly, including addresses on this domain's earlier life. The honest history is straightforward: the association's online proceedings were hosted on servers and domains that changed hands and shape over the decades, this domain among them for a period, and this magazine now occupies the address as an independent publication about the field, not as the association itself. The association lives on, active under its own name and current site, and its recent conferences, Colombo in 2024 and Makassar in 2025, continue the annual record. We point every reader looking for the primary source toward the association's current channels rather than pretending to be them, in the same spirit that the guide to methods and community describes this magazine's position in the field: a reader and indexer of the record, not its owner.

Where parallel records live

The ACRS proceedings are not the only archive of their kind, and researchers cross them with the larger societies' collections. The International Society for Photogrammetry and Remote Sensing has maintained its own congress proceedings for more than a century, and its archive, browsable at isprs.org/proceedings, holds the international layer of the same history, the sessions where Asian work met the global field each four-year cycle. Between the two records, the annual regional and the quadrennial international, most of the working history of satellite mapping in Asia can be reconstructed from primary documents alone, a situation few technical fields enjoy, and one this magazine exists to make better known.
