| description | The delimitation and Spatio-temporal characterization of built-up or urbanized areas in cities is a fundamental input forterritorial planning. Built-up Zone Indices are used to identify urban areas using remote sensing. The objective of thisstudy was to evaluate the multitemporal assertiveness (1997, 2002, 2007 and 2018) of three Built-up Zone Indices (NDBI,UI and IBI) calculated in Landsat images for three Colombian cities. The images were enhanced through Remote Sensingtechniques and the Built-up Zone Indices were determined by taking into account the parameters established by theircreators. It means that 700 ground truth points (350 for the built-up zone and 350 for the non-built-up zone) were used to establish the multitemporal assertiveness using the Kappa Index. The results show that the index with the best overall multitemporal assertiveness was the NDBI (Kappa = 0.382), which was also the best performing for the largest city (Kappa = 0.566); for the intermediate size city, the most successful index was the UI (Kappa = 0.545). The evaluated indexes had nullKappa values in the city of Espinal; discarding the results obtained in the latter city, the global assertiveness of the indexes can be increased to 0.573. Further research is needed to evaluate in detail the applicability and assertiveness of the indicesin the Colombian context, as well as the adjustments to the optimal value range for each particular city according to its architectural characteristics. |

La delimitación y caracterización espacio-temporal de las zonas construidas o urbanizadas en las ciudades es un insumo fundamental para la planificación territorial. Los Índices de Zonas Construidas son empleados para identificar las zonasurbanas utilizando sensores remotos. Este estudio tuvo por objetivo evaluar la asertividad multitemporal (1997, 2002, 2007 y 2018) de tres Índices de Zonas Construidas (NDBI, UI e IBI) calculados en imágenes Landsat para tres ciudadescolombianas. Las imágenes fueron mejoradas a través de técnicas de Teledetección y se determinaron los Índices de Zonas Construidas teniendo en cuenta los parámetros establecidos por sus creadores. Se emplearon 700 puntos verdad terreno(350 para zonas construidas y 350 para zonas no construidas) para establecer la asertividad multitemporal usando el Índice de Kappa. Los resultados muestran que el índice con mejor asertividad multitemporal global fue el NDBI (Kappa = 0.382),el cual también fue el de mejor desempeño para la ciudad de mayor tamaño (Kappa = 0.566); para la ciudad de tamaño intermedio el índice más acertado correspondió al UI (Kappa = 0.545). Los Índices evaluados tuvieron valores nulos de Kappa en la ciudad de Espinal; descartando los resultados obtenidos en esta última ciudad, la asertividad global de losíndices puede incrementarse hasta 0.573. Se infiere la necesidad de realizar nuevas investigaciones que permitan evaluar amayor detalle la aplicabilidad y asertividad de estos índices en el contexto colombiano, al igual que los ajustes a los rangos de valores óptimos para cada ciudad en particular de acuerdo a sus características arquitectónicas.
