Uses and applications of georeferencing and geolocation in old cartographic and photographic document management

Abstract

Jesús Cascón-Katchadourian has a degree in history and a degree in documentation from the University of Granada (UGR). He got a first national award for his documentation studies by the Ministry of Education, Culture and Sport. He began in the world of research by taking the Master in Information and Scientific Communication of the UGR. He is currently working on his doctoral thesis on ancient cartography, georeferencing and geolocation of historical photography, hired by the UGR as a university teacher training fellow (FPU). His field of study is the application of technology to historical heritage.

Promoting the heritage of the city of San Cristobal de La Laguna through a temporal link with a 16th century map

“…This evaluation is achieved by means of the georeferencing process (Baiocchi & Lelo, 2005;Balletti, 2006;Hill, 2009), which relates the internal coordinate system of a map or aerial photo image to a georeferenced coordinate system. Its usage with the help of digitisation techniques and web publication facilitates access for non-expert users to geographical, heritage, urban or environmental information of interest (Cascón-Katchadourian et al, 2018;Talich, 2020).…”

“…In cartography (Cascón-Katchadourian et al, 2018), the georeferencing process begins with the identification of homologous ground control points (GCPs) in the local coordinate system of the image/map and the coordinate system of a support map (also known as reference cartography) (Dávila & Camacho, 2012). The process usually consists of establishing a set of reliable common locations which both coordinate systems, and that has been maintained over time (geographical features, outlines of city blocks, buildings, monuments, streets), thus indicating that those homologous GCPs are geographically the same.…”

“…The use of historical maps is a research area that has concentrated on several topics like digitization (Buonora, 2009), georeferencing (Baiocchi & Lelo, 2005;Balletti, 2006;Cascón-Katchadourian et al, 2018;Livieratos, 2006;Sancho Mir et al, 2017), or web-based information systems for data publication and access (Bachiller et al, 2020;Cascón-Katchadourian et al, 2019;Santamaria-Varas & Martinez-Diez, 2019). In this work, we will focus on these topics to develop a temporal geolocation system that can be used in the VR application and as an independent web application.…”

“…El mecanismo de indexación MapRank destaca como una implementación de la búsqueda geográfica. (Oehrli et al, 2011;Cascón-Katchadourian et al, 2018a). Ejemplos de la implementación de búsqueda de mapas en base al área que representan son la cartoteca del Instituto Geográfico Nacional de España (IGN, 2019) y el proyecto OldMapsOnline.…”

“…A más de la cartografía antigua, hay otros elementos históricos que pueden obtener una referencia geográfica (Cascón-Katchadourian et al, 2018a) explican que, a otros elementos históricos digitalizados como fotografías, carteles, croquis, etc., pueden representar un lugar geográfico y por lo tanto se pueden asignar a un determinado par de coordenadas.…”
