Spatial Democratization of Puerto Escondido 2022-2023: Socioeconomic Data (Population Density): Information Gateway

Abstract

This research presents socio-economic geospatial data for the city of Puerto Escondido, Oaxaca, derived from reliable scientific sources. It identifies recent population density data (2022-23) and visualizes them on a map. The opportunity to democratize spatial data by expanding access and participation in geographic information usage is proposed, which can have significant benefits in terms of informed decision-making, economic and social development, and empowerment of local communities for a society based on self-interest, shared values, and long-term commitment. In the learning, access, usage, and application of spatial data presented by NASA on its platforms, it is asserted that information is a public good. The sequence of this research began with a search for related works in this theme (20 filtered journals). Consultation and preparation of raster data were carried out (GeoTiff Raster, Gridded Population of the World, Version 4 (GPWv4) 2016, and Grid. Census disaggregated gridded population estimates 2022). The applied methodology involved using Geographic Information Systems with open-source software, which offers a wide range of quantitative and qualitative tools. The results: the produced cartography consists of a letter-sized sheet with two maps, one at a numerical scale of 1:210,000 and the other at 1:90,000. The obtained results indicate that the two consulted sources, NASA-SEDAC and WorldPop, are scientifically proven sites of activity. The population density configuration is concentrated near the coastline, with a tendency to disperse towards the east. Despite the difference in spatial resolution per pixel, which is 900m and 100m respectively.
