Managing agricultural activity encompasses technology, geographic information, spatial data and geomatic tools as support techniques. In this framework, agricultural mapping is an essential geomatic application due to its importance in managing food systems. This research aims to analyze the state of knowledge of geomatics tools and their applications in agriculture through a systematic review of scientific documents and methodological approaches, highlighting the use of geomatics in agricultural mapping to evaluate trends in agriculture management. The study methodology consists of a scientific base of publications on geomatics and its applications in sustainable agriculture, with a quantitative analysis of production and its approaches. Subsequently, PRISMA establishes a systematic review in search of the subject’s methods, applications and trends. The results show that of the total data analyzed, 60% corresponds to general agricultural mapping for crop/water/soil mapping using satellite images. Twenty percent for land use and coverage, considering the georeferencing that contributes to agricultural territorial planning. Nine percent consider geomatic key for agricultural cadastre (plot management). In addition, 6% corresponds to precision agriculture and 5% to watershed management. The most predominant geomatics tools are: Geographic Information System (GIS), Global Positioning System (GPS), unmanned aerial vehicle (UAV) and remote sensing (RS). Also, among the most used geomatic techniques in agricultural cartography, photogrammetry in crop phenology and multispectral analysis in the optimisation and monitoring of agricultural production stand out. Studies show that the geomatic application promotes sustainability practices such as crop rotation, seeds dispersed and germinated by animals, agricultural irrigation through rivers/basins/streams, family gardens and generation of employment sources. The geomatics use is of great utility/potential for the acquisition and generation of geospatial data accurately, with time and cost savings that contribute to the decision-making of city councils, public cadastral administrations, enterprises, educational institutions and agricultural foundations.

The development of geographic information systems has grown significantly over the past decade. Simultaneously, the concept of smart cities based on the management of large volumes of data has also spread worldwide. The digital twin concept has recently been incorporated into the technological domain of urban management. However, currently, phases such as technological integration, standardization, data and process interconnection, the development of tools and utilities, professional training, and the application of digital urban development in real-world situations are converging. This paper presents the experience developed on a university campus, detailing each of the phases carried out from the initial design to a fully operational pilot phase model. The article highlights the importance of certain aspects to consider in each phase, demonstrating that there are barriers and limitations and at the same time, great strengths and opportunities in applying the digital twin model in urban management, considering aspects such as mobility, accessibility, energy management, and involving students and university administrators in the process.
