abstract = "The objective of the present work was to quantify Fe2O3 by
laboratory and orbital sensors. The study area was a 473 ha bare
soil field located in the region of Barra Bonita, SP. A sampling
grid was established (100 m x 100 m) and the places were
georreferenced. In these points, earth samples were collected in
two depths (0-20; 80-100cm) for laboratory analyses and
reflectance obtaintion with a laboratory sensor (450 to 2500 nm).
In the same places of soil sampling collection, reflectance data
were obtained from a TM-Landsat-5 image. Most of the generated
equations showed high r2 for Fe2O3, 0,82 for laboratory and 0,67
for orbital. Comparing the intervals of iron between values
esteemed by radiometric data and values determined in laboratory
analyses, radiometric data presented a global success of 92,2%
against 91,3% for orbital data. The majority of the confusions
observed between the determined values and the quantified ones are
in an acceptable interval.",
