Accurate Maps for a Changing World

Precise aerial photography is essential to top quality mapping.

GeoOne maintains a fleet of aircraft equipped with Zeiss precision aerial equipment. These cameras provide high resolution with low distortion to guarantee optimum quality over a wide range of photo scales and climatic conditions.

The Zeiss LMK aerial camera employed by GeoOne is the most precise aerial camera in the world. It features the latest technology that includes forward motion compensation (FMC), automatic crab compensation, and a gyroscopic stabilization mount system. All these features ensure that the best possible image is produced when the camera is in operation.

The LMK is also compatible with newly developed in-plane GPS and photo control GPS systems. The benefits are better flight line control and the potential for dramatically lower costs of photo control as in-plane GPS systems offset costs of ground-based photo control.

Flight teams consist of seasoned pilots and expert aerial photographers. They apply rigorous standards to capture high quality photographic information.

Quality Control

Clarity, sharpness, and consistency are the top criteria for aerial photos.

Control of the developing image is important. GeoOne's on-site, full-service photography lab provides a careful first step in the process of converting images to useful mapping information. Our skilled staff can furnish you with top quality contact prints, enlargements, mylars, photo indexes, and mosaics.

Photo Library:

There is always a need for historical documentation. GeoOne possesses aerial photography dating back to 1966. Our film library may be the answer to your need of historical data for areas throughout the Midwest and southeastern regions of the United States.

Global Positioning System (GPS)

When high levels of accuracy are required, when weather threatens a project, when distance or terrain separates control points, or to save time and money, GPS is often the superior solution. Often, GPS control points can be established at a fraction of the cost of a conventional survey.

The GPS, using signals from orbiting satellites to pinpoint locations on earth, is the most accurate system ever devised - providing information five to ten times more accurate than conventional surveys.

GPS was devised by the military for navigation and targeting systems. Today, commercial airlines are geared up to use GPS as a navigational system, as the accuracy permits pilots to perform difficult instrument landings in inclement weather.

Important civilian uses include determining coordinates of natural and man-made objects for database development. These have been used successfully to manage large spatial information by offices such as government planning and engineering, assessors and auditors, fire departments and utilities.

GeoOne combines GPS with conventional and technical methods to create the most efficient approach for your mapping needs.

Photogrammetry

Photogrammetric stereo compilation is the foundation of every good map.

GeoOne photogrammetrists are highly educated professionals in the science, seasoned by an average of nearly twenty years of successful experience in all phases of photogrammetry.

GeoOne provides topographic and terrain elevation information in the form best suited to your application. Options include contours, gridded or triangular surface models, breaklines, profiles and cross-sections.

Accuracy ultimately depends on the photo interpretation skills of stereoplotter operators and precise equipment. Our experienced operators using state of the art analytical plotters and softcopy technology allow us to deliver the high quality mapping services our clients require.

Editing

The function of editing is to identify variations from the required map content.

The GeoOne editing staff works closely with photogrammetry and GIS personnel, using meticulous care to review data. For each project, they check that data is correctly categorized, add text and include attribute information, grids, title blocks and plotting sheets.

Editing provides an extra level of quality control. It helps assure the technical integrity of the digital map data as well as its aesthetic and cartographic soundness.

The combination of advanced technology and old-fashion attention to detail results in a more reliable, more useful map. Map products are provided in popular CAD and file formats, in hard copy, tape and diskette media.

Geographic Information Services

A Geographic Information System (GIS) is a combination of computer hardware, software and geographic data organized to efficiently capture, store, integrate, update, manipulate, analyze, create and display all forms of graphically referenced information.

GeoOne technical personnel are expert in developing new GIS databases and systems for corporate clients. We have acted as professional to customize city and county government systems. Equipped with state-of-the-art hardware and software, we can help you define and develop accurate geographic base maps tied to detailed, textual information.

GeoOne can help you create a custom database, train your staff in GIS, and develop programs and macros that make your complex queries as simple as clicking a mouse.

GIS technology developed around 1970. At first, it was used by organizations such as NASA, the U.S. Fish and Wildlife Service and the U.S. Marine Corps. Since then, GIS has evolved to serve diverse applications - such as mapping forests, water and other natural resources; topographic mapping, marketing and facility information; land use planning, teaching and scientific research.

GIS links traditionally separate sources of information to a common geographically - referenced database. GIS makes it possible for the user to make sophisticated queries of graphic and non-graphic information. GIS allows greater flexibility for the primary jobs of making, recording and processing maps.

This fast-growing technical tool integrates and references information to form a spatially referenced database - easily accessed by a wide range of users and with virtually limitless applications.

Digital Orthoimagery

Digital orthoimagery joins your mapping information with its photo image.

Digital orthoimagery provides an accurate, cost-effective and flexible foundation for your GIS database. It combines the accuracy of a photogrammetrically-scaled map with the inherent wealth of information provided by an aerial photograph.

GeoOne can create (or help you create) custom-tailored maps using black and white or color digital orthoimagery. GeoOne's experienced staff gathers elevation information to perform orthographic corrections using analytical photogrammetric equipment and/or satellite imagery.

Orthoimagery can be used as a base for constructing and aligning overlays of geographic features such as zoning, property lines, natural resource boundaries, utility networks and other features not visible or easily discernible on a photograph.
