Total station series
Topcon Positioning Systems’ new total station series—the GPT-7500 and the GTS-750—feature rugged, small, light units with increased performance at the same price as older models. The total stations have a 400-MHz Intel processor running Windows CE and a 6,562-foot non-prism range (GPT-7500). The instruments are available in 1-, 3-, or 5-inch accuracy models. The 1- and 3-inch versions have dual displays; the 5-inch version has a single display. Features of the series include TopSURV onboard software; large, backlit keypad with bright, color LCD touch-screen; CF card, USB Type A, and USB mini-slots offering storage and transfer options; increased battery capacity and operating time; and 8 percent smaller size than previous models.

GIS extension animates feature data
Applied Science Associates, Inc.’s (ASA) TimeSlider is an extension for ArcGIS 9.1 that provides functionality to animate feature data that has date and time information. ASA’s TimeSlider extension allows ArcMap users to specify a field that contains date and time information for geographic features. The TimeSlider can manage multiple time-varying layers, including layers that have different time steps. The TimeSlider extension has been used to manage time-varying data such as time series observation data from multiple points (current meters, wind stations, water quality sensors), and numerical model results (oil spills, hydrodynamic simulations, sediment transport). The TimeSlider extension is available for free download and use via the ASA website at www.appsci.com/downloads.

Total stations designed for grading operations
Trimble recently introduced the Trimble SPS730 and SPS930 Universal Total Stations featuring Servo, Autolock, Robotic, DR Reflectorless, and ATS modes of operation. The Trimble SPS930 is designed to be accurate to 1 arc second in the vertical and horizontal angles; the SPS730 is designed to provide 3 arc second accuracy in the horizontal plane and 2 arc second accuracy in the vertical. With a fixed, low latency, synchronized data and a 20-Hz update rate, the Universal Total Stations are designed to allow users to track a machine target and know the data is being passed from the instrument to the machine as quickly and accurately as possible so a motor grader or dozer operator can conduct real-time fine grading operations to millimeter accuracy.

GIS parcel-editing tools
The latest version of ESRI’s ArcGIS Survey Analyst with Cadastral Editor features new parcel-editing tools that enable users to record and maintain survey data and continuous parcel layers as elements that are part of an integrated dataset and data model, called the cadastral fabric. With the latest release, record data can be held in a continuous database supporting a GIS system for complete spatial data management and analysis. With ArcGIS Survey Analyst 9.2 users can store both a continuous parcel fabric as well as survey-based subdivision plans without loss of any information in the original survey record, incrementally improve the accuracy of cadastral representation as each new subdivision or survey plan is entered, and track parcel history and lineage by maintaining data such as surveyor record and the legal recording dates. The new features and capabilities were released as part of the ArcGIS 9.2 Service Pack 3.

3-D LiDAR scanner
Riegl USA, Inc., says its Riegl 3-D LiDAR Scanning System provides a high-speed, end-to-end solution for civil engineering projects. The LMS-Z420i—which the Federal Bureau of Investigation Lab used in support of the National Transportation Safety Board to conduct a structural analysis of the collapsed I-35W Bridge in Minneapolis—has a horizontal scanning range of 360 degrees and a vertical scanning range of 80 degrees, with a measurement rate of 8,000 points per second within 6-millimeter accuracy. A series of photo images are also taken in each scan position by a calibrated Nikon digital camera. The calibrated photo images can also be mapped to LiDAR spatial data within 1 pixel accuracy.

GIS data collection software
Leica Geosystems, Inc.’s MobileMatriX is a multi-sensor, mobile GIS software program designed to operate on Tablet PCs as an extension to ESRI’s ArcGIS desktop platform. It has integrated survey processing functionality in the ArcGIS environment with real-time links to a variety of surveying instruments, such as GPS sensors, total stations, and digital levels. The new Leica MobileMatriX Version 2.1 can log GNSS raw data and allows users to post-process the data with Leica GeoOffice Surveying and Engineering Software, then re-import the post-processed points back into Leica MobileMatriX. According to Leica, by using raw data logging and post-processing techniques, field crews can focus on efficiently mapping as many structures as possible, without being concerned with real-time connections and accuracy results. If post-processing the first time doesn’t provide the expected results, users can re-process until the required level of accuracy is achieved.
