LANDSAT5 Satellite View of Bicas,Minas Gerais,Brazil in 1993-06-24 (RGB=bands 3,2,1 - real color - sharpened), with 30m resolution per pixel and constrast+sharpen filters applied. Compare with its original counterpart in Image:P217r75 5t19930624 bicas rgb bandas 321.png. The city of Bicas is visible as a milky spot in the centre, and the city of Guarará as a thin "half-moon" linked to the southeast part of Bicas. Due to the sharpening, the roads are much more readily visible, such as the BR-267 crossing from west through the village of Santa Helena, the south of Bicas, the north of Guarará and eastwards to the city of Maripá. The winding road (in the end becoming a straight line leading to northeast) going to Rochedo and São João Nepomuceno is also visible on the north of Bicas. The road MG-126 is visible coming southwards from the south of Bicas, leading to Pequeri and Mar de Espanha. Several other smaller roads are visible, such as the road to Saracura, in the northeastern parts of Bicas, and the road leading to Forquilha, in the southeast of Guarará. Large areas of naked land are visible as big yellowish-orange spots, such as the "Alto das Brisas" hill, in the middle of Bicas. 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.

The individual band frequencies 3,1,2 corresponding to the RGB colors, with resolution of 30m per pixel (according to the band specifications of the TM sensor (http://www.eurimage.com/products/landsat.html) of the LANDSAT5 satellite (http://landsat.gsfc.nasa.gov/education/compositor/), { Band Number Wavelength Interval Spectral Response 1 0.45-0.52 µm Blue-Green 2 0.52-0.60 µm Green 3 0.63-0.69 µm Red 4 0.76-0.90 µm Near IR 5 1.55-1.75 µm Mid-IR 6 10.40-12.50 µm Thermal IR 7 2.08-2.35 µm Mid-IR }), were made available by the source above, for free use, in the address http://glcfapp.umiacs.umd.edu:8080/esdi/ftp?id=14492 (also in ftp://ftp.glcf.umiacs.umd.edu/glcf/Landsat/WRS2/p217/r075/p217r75_5t19930624.TM-EarthSat-Orthorectified/).
