What is a Data Collector?

A data collector is an electronic device that records precise measurements of coordinates, angles, distances, elevations and more. It is considered as a handheld field computer because it is equipped with a microprocessor, internal memory for data storage and wireless capabilities for connectivity and data transfer. This device is battery powered, portable, has a touch screen LCD display and built-in field software that boost efficiency and productivity in topographic surveying, mapping, and construction projects. In addition, it can be used in conjunction with total stations and personal computers for viewing, analyzing and manipulating collected land data.

The All-in-One Mobile Workforce

These days, many people own more than one portable electronic device, each dedicated to a different function. This Spectra Precision field controller combines all the functionality needed in one convenient handheld device by offering a topographic field computer and a smartphone in one. The Spectra T41 has an integrated 8-megapixel camera with flash and geotagging for capturing detailed and high-quality images in the survey area. Geotagging is the addition of a current geographic location to the image or video using this device’s integrated GPS receiver within 2 to 4-meter accuracy. This feature is very practical in the field because it helps you find a variety of location-specific information efficiently. With integrated Bluetooth capability, the T41 data collector can transfer data wirelessly to a PC and can easily connect to other Bluetooth devices and field instruments. In fact, this device can also be connected to multiple total stations, each saved with their unique settings.

Forget about juggling multiple electronic devices! This surveying tool for data collection has a built-in SIM card slot giving you the freedom to make phone calls and send SMS text messages to your clients or project managers while in the field. It utilizes a 3.75G cellular data transfer on GSM cellular networks worldwide. This recent release of 3G provides mobile broadband or Internet connections to smartphones and laptops. Therefore, you can upload and download survey data from a cloud or online storage system using Wi-Fi or WWAN (Wireless Wide Area Network) connections. Cloud storage helps you turn a personal project into a collaborative effort by allowing the sharing of files from any location or device that has Internet access. The Spectra T41 also has an accelerometer that detects movements and rotates the graphics on the screen accordingly. In addition, the electronic compass determines the accurate direction even while you’re standing still. Without a doubt, this all-in-one portable device reduces total time and cost.
