This technical note provides instructions for adding logical or ‘Yes/No’ steps to a GeoCue checklist. These types of steps can be useful for tracking work that is not linked to a particular production tool. A common example would be adding a “Ship Data to Client” step at the end of a workflow. They can be…
GeoCue offers limited support for Mean High Water Tidal Datums. In GeoCue 2013, thirty-eight Mean High Water project areas (aka VDatum project areas released by NOAA on 13Aug2013) are supported and others will be added as they become available from NOAA. The twenty-five older VDatum project areas are also still included in the product. Transformation…
In the previous articles we provided an introduction to coordinate systems, geoids, datums and projections. This background information was needed in order to delve into more details on transformations and changing projections in the various software packages to help you do more with LIDAR data. This article will provide the information into transformations and changing…
The NOAA Mean High Water (MHW) files (mhw.gtx) and the corresponding TSS files (tss.gtx) can be used to create GeoCue vertical datum grid files that support the Mean High Water Tidal datum in GeoCue. One MHW/TSS pair exists for each of the thirty eight NOAA defined coastal project areas. This note describes the GeoCue workflow…
Geoid models in GeoCue are grid-based. The required file format is simply a rectangular grid of geoid undulation values, N, where h = H+N, with h representing the ellipsoid height and H the geoid height. The grid contains only undulation values. The grid points are required to be at regular geographic intervals in latitude and…
There are some different two approaches that one can take to provide the desired surface from bridges for use when rectifying orthophotos. You may even wish to use a combination of the them. One method would be to comb through your dataset using the QAQC Toolbar to methodically look for bridges and then use the manual…
In the previous article, we briefly mentioned coordinate systems while looking at how they played a role when defining the MicroStation design cube and setting up the Terrasolid software. A brief mention was fine for that setup, but if we wish to delve into more details on transformations and changing projections in the various software…
GeoCue 2014 is the major GeoCue feature upgrade release for 2014. GeoCue has now been in heavy day-to-day production (in commercial release) for about 10 years. Many of the new features that have appeared in GeoCue are a direct result of the feedback that we received from our user base of GeoCue customers. One significant…
Download the GeoCue 2014 Installation Guide. This guide will discuss the details of GeoCue installations and updates, licensing, and registration. For a typical installation using the simplified installation process, please refer to the GeoCue 2014 Quick Install Guide. This is recommended for most new installations. For a typical update of an existing GeoCue installation using…
