Topographic Surveys
Today"s ever changing technology requires flexibility in the collection of topographic surveys. Topographic surveys involve the data collection of three dimensional data and subsequent generation of design files, triangle files, and digital terrain models. These services can be collected via conventional data collection with total stations and data collectors, or via real-time kinematic GPS surveys.
JMT offers extensive experience in providing topographic surveys and design map production using both of these formats for electronic data collection. By using various data collection programs, JMT is able to generate design files in either Microstation or AutoCAD, with the appropriate digital terrain models. JMT is also able to adhere to specific CADD standards required by various public agencies, and is also able to input our data directly into specific GIS formats. JMT has the ability to use TDS Ranger, Carlson, or Allegro data collectors, as well as either Leica or Topcon dual frequency GPS receivers. JMT also uses Network GPS which allows for all of our GPS receivers to act as rovers and collect topographic information, saving both time and cost, JMT`s topographic surveying experience includes supporting a wide variety of projects, including transportation corridor design and construction support by creating three dimensional terrain models. The flexibility to provide design files in multiple CADD formats allows JMT to meet any specific client need.
