Sin embargo, en Costa Rica, la información detallada de la cartografía digital sólo está disponible después de la introducción de las imágenes Landsat y los Sistemas de Información Geográfica (SIG) en la década de 1980's. Por lo tanto, es crucial recuperar información de las hojas cartográficas históricas para proporcionar una mejor línea de base histórica. En este artículo se explica el proceso de conversión y corrección del mapa digital de coberturas del suelo de la primera edición de las hojas cartográficas de Costa Rica, publicadas inicialmente en papel por el Instituto Geográfico Nacional (IGN) a escala 1:25.000, basándose en fotografías aéreas tomadas en 1945. Estas hojas cartográficas contienen información valiosa sobre las coberturas terrestres de bosques, humedales, manglares, salinas y cuerpos de agua. Por lo tanto, el objetivo principal de este proyecto fue crear una capa única y corregida de coberturas naturales del suelo en formato digital para la Península de Nicoya, de acceso libre y gratuito al público a través de la plataforma del Sistema Nacional de Información Territorial (SNIT) del Instituto Geográfico Nacional de Costa Rica.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Land cover maps are crucial for understanding land use change and for conserving and wisely managing natural resources. However, detailed digital mapping information was only available in Costa Rica after the introduction of LANSAT images and the use of Geographic Information Systems (GIS) in the 1980s. Therefore, retrieving information from historical cartographic sheets is crucial to providing a better historical baseline for the Nicoya Peninsula of Costa Rica. This article explains the process of converting and improving the land cover map from the first edition of the cartographic sheets of Costa Rica into digital format. These sheets were initially published in print by the National Geographic Institute (IGN) at a scale of 1:25,000, based on aerial photographs taken in 1945. These cartographic sheets contain valuable information about the land covers of forests, wetlands, mangroves, salt pans, and water bodies. Hence, the primary objective of this project was to create a single and improved layer of natural land covers in digital format, which will be free and open access to the public through the National Territorial Information System (SNIT) platform of the National Geographic Institute of Costa Rica.]]></p></abstract>
