High-resolution satellite images, such as this, are valuable tools for integrated urban planning. The 1-meter resolution of the images enables users to quickly and accurately interpret urban landscape features in order to develop better landuse plans. Roads, bridges, culverts and other physical infrastructure, rivers, khals, water bodies, drainage channels are clearly visible in the images. Urban vegetation cover can be well identified using the different spectral bands of the image. Discontinuous or sparse vegetation, vegetated, urban surfaces corresponding to light density housing, vegetation surrounding roads, gardens, urban parks and lawns as well as crops in surrounding rural areas can be mapped. Urban lands use classification is also possible that helps monitor land use changes in urban areas.
Using image processing and GIS technology, the Center for Environmental and Geographic Information Services (CEGIS) analyses high-resolution images from IKONOS and Quickbird satellites to support urban planning and management of natural resources.
