Map scanners are commonly used across a variety of industry sectors, where a crisp and clear image is of primary importance. They are used by a range of customers, from university departments to architects and engineers who use technical digital images on a day to day basis. Colortrac large format scanners offer cutting edge precision images which are ideal for aerial or satellite photographs, GIS and cartography. They offer a low cost scanning solution for the creation of high resolution images.

Choosing The Right Map Scanner

Choosing a map scanner can be more difficult than you might think; with different types of imaging technology on the market, picking the right scanner to meet your needs can feel like finding a needle in a haystack. Modern scanners offer more functions than ever before so it’s essential you know which technology best fits your user needs. A customer who intends to primarily scan old documents will benefit from a different machine to someone who plans on scanning aerial photographs.

There are three key types of scanning technologies currently available which can be used for mapping. These are Charge Coupled Displays (CCD), Contact Image Sensors (CIS) or the unique SingleSensor scanning technology which has largely replaced the older CIS devices. The CCD technology scanning works in a similar way as a traditional camera, whereby the light passes through multiple lenses and the images are captured with multiple “cameras” using CCD sensors. This method is better where thicker media such as maps fixed to foam board or where a higher depth of field may be required. This can be of considerable benefit when scanning old documents. The SingleSensor digital imaging technology is a Colortrac invention that uses up to 50,400 individual sensors in a straight line across the width of the scanner. This SingleSensor technology is substantially lower cost than CCD, yet it produces high image quality and color reproduction approaching that gained from a CCD device. It’s ideal for scanning thin media and it’s a much more versatile and portable technology.

Map Scanners Innovation

The modern GIS and map scanners combine high resolution with sharpness resulting in exceptional image quality and high dimensional accuracy. Colortrac scanners are available in a variety of specifications depending on your requirements; various widths are available which can scan maps up to E+ and A0+ in size. Advanced paper transport is available to safely transport old and fragile maps. Colortrac scanners are incredibly diverse in scope; previously they have been used to scan First World War trench maps and to produce a 3D digital terrain model for a battlefield satellite navigation system. The possibilities of what you can do with Colortrac precision are only limited by your imagination!

Why To Have A Map Scanner In-house?

GIS and map scanners make an excellent addition to in-house office technology. All Colortrac scanners are designed with their environmental and low energy requirements impact in mind. This ensures that the scanners are sustainable, economical to run and promise a long life. A GIS / map scanner is a real investment which will allow your company to digitally archive delicate and fragile documents in-house. This function increases security, minimizes the risk of loss and damage to your irreplaceable or vulnerable documents and reduces overall space occupied by storing.
