AgroNLP – Web application for natural language queries (NLP) on agricultural databases using the Deep Seek api

2025-06-21T16:35:12+00:00

The development of artificial geointelligence represents a technological advance in projects managing large-scale geospatial data. In Cuba, initiatives like the agricultural cartographic database project stand out. This paper introduces AgroNLP, a web application enabling natural language queries on a PostgreSQL/PostGIS agricultural database, generating NL responses via the DeepSeek API (deepseek-r1:free). The solution integrates an LLM fine-tuned to interpret queries and generate contextualized SQL, following an MCP-like approach. Built with Next.js, PostgreSQL/PostGIS, and Deep Seek, it removes the need for SQL expertise. Its novelty lies in agricultural specialization and geospatial capabilities, outperforming generic tools like Claude [4].

Topographical securing for drives it of piles in a marine environment

2025-06-21T16:51:43+00:00

The work is developed in the field of the topography and he/she has as objective to explain how it was located and it controlled the final position of the 330 piles of reinforced steel, sunk in the marine channel of the bay of Havana. To achieve this objective, it was necessary to carry out a series of topographical works that you/they assured this positioning. The main obtained results of this insurance go by a series of tasks that you/they embrace, from the rising of the objects under the water, - that can block the it sinks of the piles -; the densification of the topographical bases in front of each line of piles, - that assure the I restate and the executive risings of the sunk piles -; the determination of the geographical coordinates of the permanent buoys of security; the Systems of having guided and control of it sinks it of piles in the sea, by means of technology GNSS (Global Navigation Satellite System - Global System of Sailing for Satellites); the I restate of the position of each pile from their cylindrical front face; the mensuration and pursuit of the record parameters of it sinks; until the realization of the executive rising of the shirts (heads) of the sunk piles.

Specialized Cartographic Base for the Military Agricultural Union and its Spatial Data Infrastructure

2025-06-21T17:15:28+00:00

With the aim of implementing a geospatial information management system for decision-making at the territorial level in the entities of the Military Agricultural Union (UAM), a specialized cartographic base is created with its corresponding compatibility with the land tenure registry and units of the UAM, as well as the cartographic location in the Spatial Data Infrastructure (SDI) of the facilities. that intervene in the production process. This includes entities for the production, collection, marketing of products or other facilities of interest. On the other hand, it will be necessary to implement an up-to-date maintenance service of information related to land use and tenure based on the use of satellite images and conciliation with the UAM entities in the territory, all of which will make it possible to establish an agricultural management system. and it will create the bases for the future implementation of a monitoring system in correspondence

with the technological charter of the crops where variables such as net planted area, yield analysis, state of the agricultural plot, weeds, moisture distribution, among others, are determined. In addition, the workflow will be established with the periodicity and equipment that the crop demands, managing to establish a work team in the territory that includes the personnel and air vehicles that the task demands.

Cadastral lifting topofotogramétrico integrated (LTI) in an urban area

2025-06-21T17:26:13+00:00

This focuses merges it better of the modern photogrammetry, the classic map and the GNSS technology, by offering a precise, efficient and versatile, ideal lifting for projects that requires high accuracy and details

Geodetic Reference Systems. Evolution and current trends

2025-06-21T17:46:11+00:00

The article addresses the current trend of Geodetic Reference Systems (GRS), given that positioning technologies using Global Navigation Satellite Systems (GNSS) guarantee global coverage, with high operability and accuracy, which have replaced conventional systems and allow for adaptation to the International Terrestrial Reference Frames (ITRF) defined by the International Earth Rotation and Reference Systems Service (IERS). A novel and important aspect that contributes to science and technology is the methodological approach of the article, which argues the evolution and current trends of GRS, summarizing the way to adopt an ITRF.

The benefits of adopting an ITRF as a GRS (Geodetic Datum) are presented; as well as the inconsistency of local GRS for scientific studies on geodynamics; which constitute an obstacle for integration into projects scientists at the national, regional, and global levels.

Proposal for a spatial model to evaluate risk indicators of climate change impacts

2025-06-21T17:55:44+00:00

Here is now a general consensus in the scientific community that the increase in greenhouse gas concentrations as a result of human activities is the unequivocal cause of the current warming of the atmosphere, oceans, and land.

A spatial disaster risk model is an approach that integrates territorial variables to analyze and geographically represent the vulnerability, threats, and capabilities of an area in the face of potential disasters and is a key step in the climate change adaptation cycle. This proposed spatial model for

The results obtained from its application on the Isle of Youth were characterized by the evaluation of risk indicators for climate change (CC) impacts, combining quantitative analysis, expert heuristics, and geospatial technologies. The model seeks to overcome fragmented approaches through a dynamic platform adaptable to local and national scales, providing analysis for the assessment of climate change impacts from the perspective of watersheds.

Evaluating vulnerability and risk indicators for the impacts of climate change by watershed allows for the modeling of specific watersheds, a spatial representation—through layers of geographic information—of climate impacts, the construction of various hazard, exposure, and vulnerability maps, and the identification of risk sites in the special municipality of Isla de la Juventud. This allows decision-makers to establish the most appropriate strategies for addressing climate change in the territory.
