Satellites can cover larger amounts
of area, but Nearmap's planes can offer
aerial shots with better resolution. "That's
really the key," Agresta says. "We have this
balance between coverage and resolution
which is one thing that makes us unique."
Each pixel in a Nearmap image represents 2.8 inches on the ground surface. "If
you're talking about the satellite world, the
vast majority is one foot to one meter," he
says, noting that the company offers more
precision in its photos.
"We can see cracks in the street," Agresta
declares, adding that Nearmap also provides
its customers with strong visibility of building rooftops. "We can distinguish a skylight
from a solar panel."
Nearmap also can get the imagery to its
clients quickly. "We've figured out and built
routines that allow us to process massive
amounts of imagery in the Amazon cloud,"
he says, noting the company can stitch the
imagery together and color balance the
photos "within days of capture."
Nearmap covers nearly 70 percent of the
United States with its photography multiple times per year. "We're flying where
the people are," Agresta says, noting that
it usually flies during the spring, summer
The spring is a particularly key time. Before leaves are on land, its clients will have
a better view of the ground. "If you're doing
large-scale construction, you want to see the
presence of water or any debris that might
be in the area," he says.

The company, Agresta adds, has to act
quickly when taking spring photos in the
upper Midwest. Although the snow has
melted, summer is quickly on its way. However, "We've been able to do that with the
fleet of planes we have because of the speed
of our capture process," he asserts.
Nearmap offers three types of imagery
to its subscribers, Agresta says. Nearmap
Vertical imagery gives clients a top-down
view of the land. Nearmap Panorama
allow users to visualize any size geography in an uninterrupted way. Nearmap
Oblique images allow them to see heights
of buildings, as well as measure them via a
cloud-based application called MapBrowser. Anywhere users can gain access to the
Internet, they can see all Nearmap imagery
within a single interface.
If a user in the construction industry
needed to modify a building, the Oblique
image would prove highly useful. "If you
want to measure the height of a building,
you can use our measurement tools to do
that," he says.
"We're also able to show you the imagery
from different cardinal directions," he adds.
"You can see what's behind the building,
and what's on the side of the building using
north, south, east and west captures."
The company recently introduced its
Panoramic imagery, giving users the ability
to view landscapes uninterrupted. "It allows
you to analyze the imagery at the speed of
the human mind," Agresta says. Users can
quickly and intuitively navigate over small,
medium or large geographic areas.
Nearmap delivers its imagery through
