High-resolution digital elevation model constructed from photogrammetric processing of drone images taken at Klados Gorge, Crete, Greece in 2017. The authors used Agisoft PhotoScan for the photogrammetric processing and to generate 3D spatial data for further use.

Malthi provides a nearly unique example of a fully excavated Middle Hellenic (MH) settlement. The excavated remains include a series of houses, storage facilities, entrance ways, and possible public architecture, enclosed by a settlement wall. Malthi is perhaps the first MH site at which a major restructuring of the settlement architecture was observed, as proposed by Valmin. The PIs research focuses on the socio-cultural motivations for the decision to make substantial revisions to the urban layout, as well as impacts on the life of the settlement and the surrounding area. PIs Rebecca Worsham, Prof. Donald Haggis, and Prof. Michael Lindblom collaborated with SPARC researchers to produce an accurate and analysis-ready plan of the exposed standing remains and a digital elevation model (DEM) of the settlement at Malthi, using a combination of scanning and structure from motion techniques.

This work was embedded in a larger project, and aimed to reconsider the architecture of the site including prior identifications of room types (by Valmin), and to attempt to identify coherent buildings. This improved survey, mapping and interpretation exercise was intended to support a rethinking about the settlement’s organization, and re-organization, as a whole. The production of a local DEM of the site was intended to aid in a consideration of access routes and forms a starting point for establishing the role of Malthi in the larger Soulima Valley network, which may function as a major corridor.

This upload contains the report and associated images submitted to SPARC of the Malthi project undertaken in 2015.

Mineral resource occurrence data covering the world, most thoroughly within the U.S. This database contains the records previously provided in the Mineral Resource Data System (MRDS) of USGS and the Mineral Availability System/Mineral Industry Locator System (MAS/MILS) originated in the U.S. Bureau of Mines, which is now part of USGS. The MRDS is a large and complex relational database developed over several decades by hundreds of researchers and reporters. While database records describe mineral resources worldwide, the compilation of information was intended to cover the United States completely, and its coverage of resources in other countries is incomplete. The content of MRDS records was drawn from reports previously published or made available to USGS researchers. Some of those original source materials are no longer available. The information contained in MRDS was intended to reflect the reports used as sources and is current only as of the date of those source reports. Consequently MRDS does not reflect up-to-date changes to the operating status of mines, ownership, land status, production figures and estimates of reserves and resources, or the nature, size, and extent of workings. Information on the geological characteristics of the mineral resource are likely to remain correct, but aspects involving human activity are likely to be out of date.
