A High-Resolution Land-Use Map - Nogales, Sonora, Mexico
Entry ID: USGS_OFR_2010_1156

[ Get Data ]

Abstract: The cities of Nogales, Sonora, and Nogales, Arizona, are located in the Ambos Nogales Watershed, a topographically irregular bowl-shaped area with a northward gradient. Throughout history, residents in both cities have been affected by flooding. Currently, the primary method for regulating this runoff is to build a series of detention basins in Nogales, Sonora. Additionally, the municipality also is considering land-use planning to help mitigate flooding. This paper describes the production of a 10-meter resolution land-use map, derived from 2008 aerial photos of the Nogales, Sonora Watershed for modeling impacts of the detention basin construction and in support of an “Early Warning Hazard System” for the region.

[Summary provided by the USGS.]

Purpose: The results will be used for modeling impacts of detention basin construction and also as a part of a larger project to develop an "Early Warning Hazard System" for the region. This dataset was created to be used as input to the Automated Geospatial Watershed Assessment (AGWA) Tool, in order to predict runoff in this urbanizing Watershed.
