LANDSAT5 Satellite View of Bicas,Minas Gerais,Brazil in 1993-06-24 (RGB=bands 3,2,1 - real color), with 30m resolution per pixel and only contrast filters applied. Compare with its sharpened counterpart in Image:P217r75 5t19930624 bicas rgb bandas 321 realcado.png. Bicas is visible as a milky spot in the centre, and Guarará as a thin "half-moon" linked to the southeast part of Bicas. Roads also are readily visible, such as the BR-267 crossing from west eastwards through the south of Bicas and the north of Guarará. The winding road going to Rochedo and São João Nepomuceno is also visible on the north of Bicas. The road MG-126 is visible towards the south of Bicas, taking to Pequeri and Mar de Espanha. This picture covers roughly 14400m west-east and 10800m north-south. The centre of the picture is located around Latitude 21S43'20 / Longitude 43W03'30.
