Trimble Access Geoid File and Shift Grid
Just installed the Demo for Trimble Access. Since my projects use custom geoid file and shift grid, where do i need to place those files in order to be used with Trimble Access?
-Also i signed up for a demo license. It says that you are limited to 30 points and a 30 dya trial. Does this mean that after the 30 days you cant store a single point?
Thank You. Some more questions that came up after my first day of evaluating it if i may
-Access asks for project reference heights. Since i'm only going to be doing gnss shots, i suppose it does not matter at all? I enter 0 as value
- You also get a sea level correction option. Should i keep this checked when work on grid
-My base station is lways on a known point. How do i keep that stored so that i dont key in the coordinates each time
- Are you creating a new job each day? You should have a point stored as your base and just set it up on that. Not sure why you would key it in more than once.
- If you're working on the grid make sure you have the needed information set in your job parameters. This why it will properly scale your ground measurements to grid when using a total station.
- If you gave more information on how you are setting your job up in this as far as the data and projection, I could probably render more help.
The manual is quite useful for explaining Access's nuances.
If a point has no elevation, the General Survey software uses the project height in Cogo calculations.
If you combine GNSS and 2D conventional observations, set the Project height field to approximate
the height of the site. This height is used with 2D points to calculate grid and ellipsoid distances from
measured ground distances.
In 2D surveys where a projection has been defined, enter a value for the project height that
approximates the height of the site. You need this value to reduce measured ground distances to
ellipsoid distance, and to compute coordinates.
