NIB landforms are typically 400-1000 m in diameter and 30-100 m deep and are invariably surrounded by steep walls cut into one or more basaltic lava flows. NIB landforms lack evidence for a primary volcanogenic origin through either collapse or youthful eruptive activity. In the Pliocene portion (4 - 2 Ma) of the Plio-Quaternary Camargo volcanic field of Chihuahua (México), they are relatively numerous and are best developed at the margins of a gently sloping (3-5°) basaltic lava plateau and near major fault scarps. Mature NIB landforms have ring-like circular drainage patterns and central elevations marked by small volcanic necks and associated radial dikes intruded into basaltic scoria-fall and /or agglutinate deposits. We interpret NIB landforms to be erosional in origin. They develop where a cinder cone is surrounded by one or more sheet-like lava flows from one or more separate subsequent vents. Once eruptive activity ceases at the younger volcano(es), fluvial erosion gradually produces a ring-like drainage pattern along the contact between the lava and the older cinder cone. As a response to a marked contrast in resistance to erosion between lava flows and unconsolidated or poorly lithified pyroclastic deposits, the older cinder cone is preferentially eroded. In this manner, a ring-shaped, steep sided erosional basin, preformed by the scoria cone, is produced; eventually fluvial erosion exposes the central neck and dikes. The volume, relief, and age of the volcanic field are key factors in the formation and preservation of a NIB landform. They form in volcanic fields where lava emissions are sufficiently vigorous to engulf earlier cinder cones. Relief and associated high rates of fluvial erosion play an important role in NIB development, as demonstrated by their locations in the Camargo volcanic field. Fully developed NIB landforms are not found in Quaternary volcanic fields, probably because erosion has not had sufficient time to generate their characteristics features. NIB landforms are also absent in Miocene fields, because erosion has proceeded too far, and thus has completely removed any NIB landform that may once have existed. The Camargo volcanic field is the only major area of Pliocene intraplate eruptive activity in northern México, and the only place where NIB landforms are relatively abundant.

Technology is modifying our environment, in such a way, former generations could not experience. Both, science and technology are continuously interrogating about the different forms on how physical world and humanity are interacting. Based on this integration of knowledge, Geomatics/Geoinformatics was born, in which most-recent objectives and procedures would have been astounding even unimaginable at the end of 20th century. In order to understand how Geomatics/ Geoinformatics has contributed to the current knowledge, it is required to precisely define the term. Due to this science is still novel, a lot of definitions try to describe it. So, the concept used in this book is that proposed by the Faculty of Engineering of the Universidad Autónoma de San Luis Potosí and it says as follows: Geomatics or Geoinformatics is focused on the use and development of both, software applications and geospatial technologies for gathering, structuring, processing and presenting (publishing - sharing) geospatially-referenced information that can be used as a support in decision-making process. The versatility of tools and processes used in this emerging science is converting her in a potential driver to be considered in diverse places of action. Despite of much people has sometime used a geospatial application on their phones i.e. Google Maps with 154 million users, they have a weak idea on what Geomatics/Geoinformatics really does. Under this perspective, Geomatics / Geoinformatics related-degree programs offered by Mexican Universities such as the Universidad Autónoma de San Luis Potosí (B.Eng. Geomatics / Geoinformatics), the Universidad Autónoma de Guanajuato (B.Eng. Geomatics), the Universidad Autónoma de Sinaloa (B.Eng. Geodesy/Geomatics), the Universidad Autónoma del Estado de México (Bachelor degree in Geoinformatics), the Universidad Juárez del Estado de Durango (MSc. Applied Geomatics), the Universidad Autónoma de Ciudad Juárez (Bachelor degree in Geoinformatics) and the Universidad de Ciencias y Artes de Chiapas (B.Eng. Geomatics), are gaining a key relevance in the important responsibility of producinghighly qualified personnel at undergraduate and graduate levels. In the same way, other challenging task is to penetrate into society for gaining acknowledgment for Geomatics / Geoinformatics professionals and related sciences such as Geodesy, Surveying, Remote Sensing, Geography, Informatics, etc. Thus, one of the most important objectives of this book is precisely, to bring the reader closer to Geomatics/ Geoinformatics world, in order to share a little of expertise gained by our undergraduate and graduate students in the context of the 4th Congreso Nacional de Estudiantes de Geomática, Geodesia y Geoinformática (4th CNEGGyG as acronym in Spanish) celebrated in the city of San Luis Potosí (Mexico) as the congress venue. So, the contributions presented in this book have used principles, methods, and technologies strictly related to Geomatics/Geoinformatics and Geodesy. Topics included in this book are a product of the reasoning and argumentation of students and professors from Mexican Universities materialized in applications of Geomatics/Geoinformatics and Geodesy over a variety of disciplines such as natural resource management, land planning, geospatial applications, and so on. Such applications are addressing complex problems with practical solutions. Therefore, this book can be used as basic knowledge for a broad audience composed by students and professionals interested in developing challenging applications related to the use of geospatial data to support/improve decision making process in a variety of disciplines. This work is not intended to be a comprehensive compendium of the basic knowledge of theoretical principles (as a classic of the book series for dummies!), or to explain the history of sciences that are supporting Geomatics/Geoinformatics and Geodesy. It is because, there is much work already done on that, so it could become a scarce reader’s interest piece of work, and then real world’s applications of Geomatics/Geoinformatics would pass to a second order. So that, the true motivation of this book is, to show fundamental characteristics of Geomatics / Geoinformatics and Geodesy, their methods, ways of application, and reliable validation approaches, leading to find diverse examples of application that elucidate both, the real scope of these sciences and required skills of logic, mathematical, computational (digital), and spatial thinking for developing projects that propose current solutions to modern-life problems. This book has been divided into four sections and includes contributions of students coursing Geomatics / Geoinformatics, Geodesy, Geology, Geography, and Archaeology at undergraduate and graduate degree programs. First section is devoted to topics related to geospatial technologies applied to Earth, Environment, Natural Resources, and Land Planning Sciences. This is the book’s largest section because it includes several applications in a variety of disciplines including social, economic and natural contexts. So, it contains contributions related with vegetation remote sensing to infer the distribution of several rock types, delimitation of mining-affected sites, identification of archaeological vestiges, risk assessment, mapping zones for forest conservation, mapping climate variability, mapping artic sea for thawing monitoring, mapping family violence, mapping optimal routes for ambulance driving, and estimating public transport demand. Second section of this book includes contributions related to web programming and algorithms for spatial data analysis. For example, you will find here contributions devoted to create software for geospatial applications and the use of freeware such as GvSIG and QGIS. Third section contains innovative applications of Satellite Geodesy and Surveying for monitoring health by using alternative positioning methods such as the Precise Point Positioning (PPP) approach or, for solving engineering problems by differential positioning using the GPS system. Such technologies allow to propose more complex works like the re- establishment of a new national geodetic network of higher throughput. And the fourth section is devoted to new approaches and technologies for geospatial analysis i.e. LiDAR, drones, virtual reality, cryptography, etc. In this part, information concerning the use of instruments and innovative proposals for geospatial analysis can be found. As examples of contributions in this book’s section, we have the use of drone technology for geomorphology and volume estimation in volcanology, site selection for precision agriculture, forest fire monitoring, mapping green spaces in cities, and geomarketing applications. All contributions presented in this book were peer-reviewed by academicians from the aforementioned educative institutions involved in the 4th CNEGGyG. So, special thanks are given to all professors who worked in the peer review process of all of each one of contributions presented in the 4th CNEGGyG. Not all works received were accepted to be in this book. So, only those contributions that fulfilled the quality standards for publication were included. Each work included in this book presents the structure of a traditional research paper in order to be easy-to-read for the rapid identification of knowledge contributions. With this, it is expected that this book can be used by professors and students as support material for some courses in undergraduate and graduate degrees of Geomatics/Geoinformatics and Geodesy. Topics included in this book are as an indication to be able for envisaging the current challenges and future perspectives that academicians, professionals, and stakeholders in Mexico will face in the process of evolution of Geomatics/Geoinformatics and Geodesy disciplines. Such a cues are satellite geodesy, advanced technologies in surveying, specialized freeware and algorithm development, and web programming. Finally, special thanks are given to all authors who participated in the 4th CNEGGyG by sending their contributions. We are sure their works really enriched the event and proceedings by injecting diversity and new insights on science.
