500 drone signals

GeoNumerics’ researchers Ismael Colomina and Pere Molina’s article “Unmanned aerial systems for photogrammetry and remote sensing: A review” cited by 500.

Castelldefels, 31 May 2018. GeoNumerics announces and celebrates that, today, the journal article “Unmanned aerial systems for photogrammetry and remote sensing: A review” has reached 500 citations according to the Scopus database. The article, published in the ISPRS Journal of Photogrammetry and Remote Sensing in 2014, was co-authored by GeoNumerics’ Dr. Ismael Colomina and Pere Molina, at the time researchers of the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC).

While reaching 500 citations at Scopus, other databases like Google Scholar offer different scoring metrics and, in this case, the database yields a total number of 819 citations.

The article covers the early developments, general unmanned aerial systems, regulations and regulators, drone navigation and orientation, sensing payloads, data processing aspects and applications. In spite of the rapid development pace of the drone mapping technology it is still a comprehensive introduction to drones for photogrammetry and remote sensing.

“It has been a rewarding experience to see how our search, sort, homogenisation and writing effort has contributed to disseminate the drone technology among the geomatics community” says Dr. Colomina, Chief Executive and Chief Scientist of GeoNumerics. “We already started working for the article in 2013 at the Institute of Geomatics (IG) and finished it while working at the CTTC.” Pere Molina, Advanced Applications Programme Manager of GeoNumerics, states that “back at that time, the drone community in our sector was facing a turning point, as drones were steadily stepping into the mapping and surveying field, yet information about drones was somehow disperse and incoherent. Today’s achievement actually confirms that need in the sector, and we are humbly proud of our contribution.”

Scopus is Elsevier’s abstract and citation database launched in 2004. It covers three types of sources: book series, journals, and trade journals and gives four types of quality measure for each title; those are h-Index, CiteScore, SJR (SCImago Journal Rank) and SNIP (Source Normalized Impact per Paper).

The ISPRS Journal of Photogrammetry and Remote Sensing (IJPRS) is the official journal of the International Society for Photogrammetry and Remote Sensing (ISPRS). The IJPRS, formerly known as Photogrammetria (1938-1989), covers sensors, theory and algorithms, systems, experiments, developments and applications. It is a high-quality, and high-impact journal as witnessed by its metrics (CiteScore 7.76, SNIP 3.004, SJR 3.169, Impact Factor 6.387).

GeoNumerics is a research and development (R&D) intensive small-and-medium-enterprise (SME) company specialised in geomatics and accurate navigation.

The CTTC is a non-profit research centre, based in Castelldefels, devoted to telecommunications and geomatics.
