Taping Over Different Ground Profiles01:12

Taping Over Different Ground Profiles

57
Taping over varying ground profiles requires careful adaptation to achieve accurate measurements. On smooth, level ground with minimal vegetation, the tape can rest directly on the ground. Here, the taping team, typically consisting of a head and a rear tapeman, coordinates their positions with clear communication. The rear tapeman holds the tape at the starting point and guides the head tapeman toward a range pole placed beyond the endpoint, using hand or voice signals to ensure alignment.On...

Errors in Taping

57
Errors in taping arise from multiple factors that can significantly impact measurement accuracy in surveying. Misalignment of the tape, often due to human error, is one primary source. A skilled rear tapeman, using a telescope, can help correct alignment by guiding the head tapeman; however, human limitations still lead to small inaccuracies. These errors may include misplacement of pins or inaccurate tape readings due to common visual confusions, such as mistaking a six for a nine. Such...

Manipulation and Analysis

48
GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

Area of Science:

  • Assistive Technology
  • Human-Computer Interaction
  • Disability Studies

Background:

  • The Tactile Maps Automated Production (TMAP) system aims to improve spatial understanding for blind and visually impaired (BVI) individuals.
  • Orientation and Mobility (O&M) specialists also utilize TMAPs to aid students in navigation training.

Purpose of the Study:

  • To evaluate the impact of the TMAP system on BVI and O&M users.
  • To gather user feedback and suggestions for TMAP system improvements.

Main Methods:

  • Semi-structured interviews were conducted with 13 TMAP users (6 BVI, 7 O&M) who had used the system in the past year.
  • Download data from the online TMAP generation platform was analyzed for each participant.

Main Results:

  • TMAP access increased map usage for BVI users from less than one map annually to at least two maps via the order system.
  • Users with easy embosser access generated an average of 18.33 TMAPs online and embossed 42 maps at home/work.
  • O&M users valued the system for creating quick, high-quality, scaled maps for students, frequently using them with braille readers.

Conclusions:

  • The TMAP system demonstrably enhances map accessibility and usage for BVI individuals and O&M training.
  • Future development should focus on user-requested features such as interactivity, greater customizability, transit stop integration, cost reduction, and nonvisual digital map viewing.
