Gould l o p m e The enclosed map was developed by the Puerto Rico Gap Analysis Project (PRGAP) and displays n t the distribution of high and low density development in Puerto Rico. The development data was i created through remote sensing analysis of Landsat ETM+ satellite imagery ranging from the n years 2000 to 2003. The classification of the images resulted in a developed land cover of Puerto P u Rico, where urban, built-up and non-vegetated areas that result from human activity were e r identified. Using additional remote sensing techniques the developed land cover was divided into t o high and low-density. High-density includes greater than 50% developed surface within a 9 ha R area, low-density is less than 50%. From a total of 95 342 ha of urban/built-up lands, 54 899 ha i (nearly 60%) is high-density development, and 40 443 ha (nearly 40%) is low-density c o development.

Land use The map was created using a mosaic of Landsat ETM+ images that range from the years 2000 to 2003. The developed land cover was classified using the Low Density Developed Iterative Self-Organizing Data Analysis Technique (ISODATA) unsupervised classification (ERDAS 2003). Developed land cover refers to urban, built-up and Landcover 140 443 ha or 43%) non-vegetated areas that result from human activity. These typically include built structures, concrete, asphalt, and other infrastructure. The developed cover was divided into high and low-density using a textural filter. Using a 300 m by 300 m window, the filter evaluates the proportion of surrounding developed and non- developed pixels of a given pixel. High-density refers to those urban pixels that are surrounded by more than 50% of developed pixels, while low-density refers to Administrative those pixels that are surrounded by less than 50% of developed pixels. ® Urban centers From a total of 95 342 ha of urban/built-up lands, 54 899 ha (nearly 60%) is high-density development, and 40 443 ha (nearly 40%) is low-density Hydrography developments. High-density development reflects the compact pattern of construction within urban centers, including cities and towns, along important Lakes/Reservoirs connections between major cities, and within exurban agglomerations that are non-contiguous with the urban centers; conversely, low-density reflects the noncontiguous pattern of development that expands outward from urban centers in linear features following the road network and isolated constructions. Some SCALE: 1: 260 000 Rivers'S treams of the biggest highways and routes are also included within the low-density developments.

Eí mapa fue creado mediante el análisis de un mosaico de imágenes de satélite Landsat ETM+ de los años 2000 2003. La clasificación no supervisada ISODATA (“Iterative Self- Organizing Data Analysis Technique”) (ERDAS 2003) fue utilizada para crear una cobertura desarrollada de Puerto Rico. Cobertura desarrollada se define aquí como áreas urbanas, construidas y sin vegetación, que resultan de actividad humana. Típicamente, estas incluyen estructuras construidas, concreto, asfalto y otra □ urbano de baja infraestructura. La cobertura desarrollada se dividió en alta y baja densidad mediante el uso de un filtro de textura. Utilizando una ventana de 300 m por 300 m, el filtro evaluó !a proporción de píxeies desarrollados y no desarrollados aledaños a cada uno de los píxeíes de la cobertura desarrollada. Alta densidad se refiere a aquellos píxeíes que están rodeados por más de un 50% de píxeíes desarrollados, mientras que baja densidad se refiere a aquellos píxeies que están rodeados por menos de un 50% de píxeies desarrollados. El análisis encontró un 95 342 ha de terrenos desarrollados en ei país, con 54 899 ha (casi un 60%) de estos de alta densidad, y 40 443 ha (casi 40%) de baja densidad. Los desarrollos de alta densidad reflejan el patrón compacto de construcción dentro de los centros urbanos, incluyendo ciudades y pueblos, a lo largo de conexiones importantes entre ciudades principales, y entre aglomeraciones suburbanas que no están próximas a centros urbanos. Los desarrollos de baja densidad reflejan el patrón no contiguo que se expande hada las afueras de ios centros urbanos de manera lineal siguiendo la red vial y construcciones a Algunas de las autopistas y rutas más grandes fueron clasificadas como terrenos desarrollados de baja densidad.
