Below is a collection of NGS publicly-given presentations that have been collected for viewing by the public. You can also view a list of upcoming presentations by visiting the Upcoming and Recent Presentations Calendar. For more information contact ngs. NSRS Modernization has, and continues to be a significant undertaking. In addition to new paradigms related to datum definitions, it has also required NGS to rethink how we collect, process, store, manipulate, and deliver data. In this session, we will review the need, and status of the major projects associated with NSRS Modernization. Changes in technology and a better understanding of the dynamic earth have made it necessary to improve the NSRS to be of better use for modern applications.

Manual opus planet 2014 pdf

There isn't currently a PDF version of the manual. We'd like to make it an option in the future, but we haven't got to that yet, and need to look into the best way to do it with the new wiki-based documentation system. The links at the top-right of the forum still point to the Opus 12 manual, but we'll be updating them. Maybe this could be considered: When user boots dopus first time a "Welcome to Directory Opus" dialog appears. The one with the check boxes: Explorer replacement, run when windows starts, Or on the homepage of the online help state that help will only by online for now? Tell us which pages need improving and we can do it. Although we are focusing on going through all the feedback from new users and still finishing parts of the manual, updating FAQs, etc. Since this is the last huge update where we hold back features for years before release, it's also the last time there will be a huge manual update that takes time to finish. We are already updating the manual as we make new changes; it's just some older to us; still new in version 13 changes that aren't all caught up, although most of the important details should be there now.

Top, E. This is the first reprocessing by the IGS, but it is expected to be repeated in the future as further analysis and reference frame changes occur. Significant errors can result if users are unaware of the potential error sources. Initial comparisons with EGM revealed no detectable slope across these patches, supporting the idea that no significant long wavelength differences exist between the aerogravity and the GRACE satellite data on which EGM is based. In light of increasing concerns about planning for Sea Level Rise, there will be a brief primer on tidal datums and usage of VDATUM software, which incorporates geodetic datums. First, a "high resolution snapshot" one-time measurement campaign with dense spatial sampling but short temporal span would be used to repair and improve existing gravity holdings. International Journal of Geographical Information Science , 24 8 , - At the ground, the downward continued gravity anomalies from the three altitudes agree within 1. Re- Localization of Location-Based Games. The former is based on the Faye anomaly, which involves approximations of the terrain effect and the downward continuation of the surface gravity residuals to the geoid. The geoid over the US Rocky Mountains is computed using two different procedures. If one or more of the topics sparks interest, the presentation will guide the user to the resources needed. Learn how NGS is striving towards this goal during this session. The goal of the project is to create a gravimetric geoid model to use as the vertical datum for the U. Since its inception in , the NCN has evolved into a vital national resource that provides critical positioning information for a wide range of applications, including surveying, construction, mapping and more.

Plus, the workshop will be alot on hands with examples and problems so everyone will need to have their own laptop. SPCS has since been adopted by many others in the geospatial community, and their input is contributing to a major update as part of NSRS Modernization. In both cases, a key objective is that these changes be done in an orderly manner and with minimum disruption. Mai, G. Contains instructions and best practices on how to submit and share GPS observations on bench marks in support of the GPS on BM campaign and development of the vertical datum transformation tool. This can be accomplished with a modernized NSRS that will provide a precise, consistent and accurate positioning infrastructure that is readily and easily accessible primarily through Global Navigation Satellite System GNSS observations. We describe the NGS calibration facility, and discuss the observation models and strategy currently used to generate NGS absolute calibrations. This led to density heterogeneities in the IGS08 network, which is not optimal for the alignment of global frames. The national shoreline provides critical baseline data for updating nautical charts; managing coastal resources; and defining U. High-frequency white noise floors can be detected in most AC orbit spectra, with an average sigma of 14 mm and larger.
