GeoEye
is the premier provider of satellite and aerial
imagery, geospatial information (information
referenced to a specific location), geospatial
products, and solutions for the national security
community, strategic partners, and commercial
customers helping them better map, measure
and monitor the world. GeoEye's world is one
seen through our Earth imaging satellites—IKONOS
and OrbView-2, two mapping aircraft, and a
global network of regional partners and satellite
receiving ground stations. GeoEye's geospatial
information supports key industries, including
national intelligence, defense and security,
air and marine transportation, oil and gas,
environmental monitoring, on-line mapping,
insurance and risk management, urban planning
and emergency preparedness.
GeoEye
categorizes its imagery products according
to resolution and positional accuracy, which
is an assessment of the closeness of the object's
location in relation to its true position
on the Earth's surface. Location error is
defined in relation to a confidence level
(i.e., range of error) of 90% (CE90)—meaning
that the object's location is represented
on the image, within the stated accuracy,
90% of the time.
The
CE90 accuracy scale can be related to Root
Mean Square Error (RMSE) as well as the U.S.
National Map Accuracy Standards (NMAS).

Applications At-a-Glance : |
Geo:
|
|
The foundation of the GeoEye imagery product
line, the Geo, is a radiometrically corrected
map oriented image suitable for a wide range
of uses. In addition to being suitable for
visualization and monitoring applications,
the Geo is shipped with the sensor camera
model in rational polynomial coefficient (RPC)
format. This camera model maps the respective
ground coordinates to image product coordinates.
Block adjustment, ortho-rectification, and
other photogrammetric processing can be performed
with the RPC camera model. This product, coupled
with a digital elevation model (DEM), permits
skilled users to make their own orthorectified
products using standard commercial software
and available data sets. Geo imagery products
are available as panchromatic, multispectral,
and pan-sharpened color imagery.

Geo Professional:
|
|
GeoProfessional products are orthorectified
(terrain corrected) by GeoEye’s staff
of experienced production personnel using
proprietary processes perfected in our production
facilities and optimized to the data collected
by GeoEye satellites. The ortho-rectification
process employed by GeoEye enables us to quickly
deliver the most accurate and precise terrain
corrected multispectral products available
from a satellite platform. Available in various
levels of accuracy, GeoProfessional, Precision
and PrecisionPlus, these products are suitable
for feature extraction, change detection,
base mapping and other similar applications.
GeoProfessional imagery products are available
as panchromatic, multispectral, and pan-sharpened
color imagery.

Geo Stereo:
|
|
Providing a strong base for
three-dimensional feature recognition, extraction
and exploitation, the GeoStereo product provides
two images with stereo geometry to support a
wide range of stereo imagery applications such
as DEM creation, building height extraction,
spatial layers, and three-dimensional feature
extraction. Stereo products in epipolar or map
projections provide RPC camera model data. The
RPC camera model supports block adjustment,
three-dimensional stereo extraction, DEM generation,
ortho-rectification, and other photogrammetric
operations. GeoStereo imagery products are available
as panchromatic, multispectral, and pan-sharpened
color imagery

.: GeoEye-1 |
GeoEye first
made history with the IKONOS satellite launch almost
ten years ago.
IKONOS, derived
from the Greek word for image, is the world's first
commercial satellite able to collect black-and-white
(panchromatic) images with 1-meter resolution and
multispectral imagery with 4-meter resolution. Imagery
from both sensors can be merged to create 1-meter
color imagery (pan-sharpened). The more than 300 million
square kilometers of imagery that IKONOS has collected
over every continent is being used for national security,
military mapping, air and marine transportation, and
by regional and local governments
|
GeoEye will again make history with
the upcoming launch of GeoEye-1—the world's
highest resolution commercial earth-imaging satellite.
GeoEye-1 will be equipped with the
most sophisticated technology ever used in a commercial
satellite system. It will offer unprecedented spatial
resolution by simultaneously acquiring 41 cm panchromatic
and 165 cm multispectral imagery.
The detail and geospatial accuracy
of GeoEye-1 imagery will further expand applications
for satellite imagery in every commercial and government
market sector.

Tafí
del Valle se volvió un "paraíso
fiscal"
Mediante
un relevamiento catastral que incluyó
la utilización de imágenes Ikonos
Geo Stereo en Tafí del Valle, Tucumán,
se determinó que más de 170.000
m2 no fueron declarados por sus propietarios.
En su mayoría se trata de residencias
edificadas o ampliadas en los últimos
años.

¿Cuál
es la mejor herramienta para la detección
de construcciones no declaradas?
¿Google
Earth: Mito o Realidad?
Tradicionalmente
los proyectos de actualización catastral,
incluyendo la detección de mejoras con
fines de recaudación impositiva se han
hecho a través de técnicas fotogramétricas
basadas en modelos estereoscópicos (3D)
de fotografías aéreas convencionales,
B&W o color, siendo la escala la principal
determinante de la precisión de los rasgos
a capturar. Más recientemente, la incorporación
de las imágenes satelitarias de alta
resolución con capacidad estéreo,
y digitales, abrió la puerta a nuevos
productos y estándares de procesamiento
y obtención de información.
En una
reciente nota periodística publicada
el 27 de agosto pasado en el Diario La Nación,
el Subsecretario de Ingresos Públicos
de la Provincia de Buenos Aires, Santiago Montoya,
destacaba que la Dirección de Rentas
detectó propiedades no declaradas por
casi 187 millones de pesos a través de
la utilización del programa Google Earth.
El objetivo de esta nota es presentar a nuestros
clientes y usuarios una descripción y
comparación de ambos métodos,
incluyendo alcances, limitaciones, equipamientos,
costos, y otras consideraciones.
