Traditionally, field work involving measurements has been
according to more or less standard procedures.
For most kind of measurements such as properties,
infrastructure etc., a team of two workers goes out in the
field armed with a steel tape for measurements, and field
books for recording results.
As they measure the building, one holds the end of the tape,
while the second goes to the next wall, reads the distance,
and draws a line on paper, labeling the distance in pencil.
They may also record field data such as lot and parcel,
address, and the name of the owner, resident, or business
at that location.
Although time tested and accepted by survey companies
as the best way they work, this procedure is fraught
(Geographic Information System) is a computerized system in which a link
is created between alphanumeric (database) information and geographic
information (computer graphic map file). These applications enable
information to be stored and retrieved as 'themes' or 'layers' on the map.
The maps themselves are based on aerial photographs. As information layers
are collected in the field, they are added to the GIS application.
2. The majority of activities
and decisions made by local governments have geographic components. These
are precisely managed by GIS, such as the following:
In all of the above areas, GIS
allows the municipality to collect the entire amount of information only
once. When updates to the information are required, the data collection
can be carried out with a minimum of effort and expense, without
disturbing the residents privacy further.
3. GIS allows information to
be distributed to various purposes in the municipality, such as
4. The GIS systems can provide
cost/benefit analyses to the municipality according to the needs and
requirements of each municipality.
5. The GIS system can serve
the needs of the municipality for internal purposes, and for the public as
a potential information consumer. In order to perform this service, the
applications are integrated among the different municipal departments. In
addition, the applications are user-friendly, so that any user, without
computer experience, can benefit from the GIS applications. The public can
access the GIS information either at the municipal offices, or online from

completed GIS projects in many municipalities. We are ready to help our
customers to install systems, in accordance with local statutory

The scale of the orthophoto is calculated
according to the relationship between the scale of the aerial
photograph and the scale of the map, and the pixel size required

About Our Orthophoto
Digital orthophotos are true
photogrammetric-grade maps. As such, they are invaluable for city planning
(land use), infrastructure planning, tax assessment, building permit
regulation, and as a base for GIS (Geographic Information System)
Aerial photographs by Orhitec are
made using state of the art cameras, which can be flown at altitudes up to
30,000 feet. Photographs can be processed in black-and-white, color, and
infrared, and can be printed at sizes up to 3x3 meters. Photographs can be
scanned at geodetic quality (negative or diapositive) to provide digital
Digital image processing of aerial
photographs to orthophotos is carried out according to the highest
standards as published by the Israel Government Mapping Institute. The
process includes geodetic scanning of negatives, orthorectification based
on DTM (digital terrain model), and mosaicing if necessary. Products are
supplied to the client on CD in TIFF format.
Orhitec is staffed by experts in
geodetic engineering, computers, and photogrammetry. Their knowledge and
ability will ensure that our orthophoto products will meet the highest
expectations of our clients.
