Leigh Surveyors Chris Power, Digital Engineering Lead, describe the trends, challenges and advantages from recent testing and deployment of mobile mapping technology. We also would need to do a traverse adjustment since it was an open traverse based on the GPS ties to several of the control points within the job. Periodically we will release information to help you improve productivity by making the most of TBCs built-in tools. It appears, if I understand correctly, that if I want to convert to a surface distance from a grid distasnce or visa versa, I would need the surveyors scale . How to Convert Map Grid Coordinates to Latitude & Longitude I'm trying to "warp" my local coordinate data to make it fit my GPS data through a coordinate transformation. These are the imaginary lines that go around and from pole to pole on a globe, respectively. On the edit ribbon there is a Ground To Grid button that allows you to quickly input the scale factor and apply the correction. There are often differences between each year. I'm not being sarcastic. Even if my local control points don't have perfect closure, the GPS points will "warp" itself to make it fit my local data showing me the northing/easting errors. New Trimble Access Software Release Powers Efficiency, Accuracy with Better Data Sharing & Understanding. transform the way work is done.

But it sounds like you were holding the occupied point and scaled from there. Similar to ArcGIS, apply grid-to-ground scale factor to the existing NM state plane definition AND to the false easting and northing values. Often it is also desirable to geo-reference the drawings to a standard coordinate system such as a State Plane Coordinate System or Universal Transverse Mercator coordinate system. NAD83 UTM Zone 12N in the coordinate system picker, you should be able to choose Copy and Modify. Once you have the coordinate system and combined scale factor figured out, you need to create a new coordinate system and multiply the false easting and the scale reduction by the combined scale factor. Carlson Software: Dimension Grid and Ground, Automatically I'm thinking that I should possibly be converting record distances from a parcel map to grid distances. This factor is computed from the x,y location of the point and the properties of the projection surface. The coordinates for the project were translated from grid to ground at the project site.

Save time with Trimble RealWorks batch import and do many processing tasks while you are away or working on something else. In order to correct for the difference between these two and bring our imagery in line with the ground measurements, we need to apply a scale factor of both direction and distance. Up-to-date background maps provide a better understanding of your surroundings and helps you make more informed decisions in the field. I have to always manually move it by reference points. Connect and share knowledge within a single location that is structured and easy to search. I'm very grateful for your guys' help and suggestions. Enter the parameters for local coordinates, grid coordinates, scale and rotation values. For example, I tried multiplying the false northing (500000) and scale factor by 0.999855 but the data does not line up with our existing ground data? Land Surveying: The Bellwether for a New Era of Infrastructure Construction. Converting from arbitrary, cartesian coordinates to UTM? GIS data, on the other hand, operates based on the spatial datas coordinate system, or grid system. And all this is by not simply applying a scale factor.

"the drawing has to be changed from ground coordinates back to grid, in preparation for a second transformation to ground at (0,0) in my local zone. My only question is, what is the use of the reference point settings? Autodesk does not warrant, either expressly or implied, the accuracy, reliability or completeness of the information translated by the machine translation service and will not be liable for damages or losses caused by the trust placed in the translation service. We GPS tied several of the control points but we are not sure on how to actually do the transformation in Autocad Civil 3D 2013 to convert the local coordiantes to GPS coordiantes. Otherwise you'll have to do it in Civil 3D manually using basic AutoCADcommands like Move, Scale and Rotate. Been a while but could you put your GPS coordinates in for the control points, apply a scale factor and rerun the fieldbook file to get grid coordinates? Go to the Survey tab and click the Local Site Settings command, Enter an estimated centroid position for your project, Check the box for "Use ground coordinates", Allow TBC to "Compute ground scale factor from the project location". Can't find what you're looking for? You say you are using Lieca. We have a survey done in local coordinates and we would like to convert them to State Plane. Normally I'd georeference the CAD file and work in a well known CRS but as your ortho is in project coordinates as well that's a bit more work. Surveyors are also free to choose a basis of bearing that is a line between two control points in the field as the baseline for a survey. This will give you the equivalent of each latitude (LA) and longitude (LO) angle in inches. Similar to ArcGIS, apply grid-to-ground scale factor to the existing NM state plane definition AND to the false easting and northing values. 1 1 I'm not sure I understand, so you may need to add more information to the question. While cartographers and their clients can accept some map distortion, engineers usually need exact distances and angles. The video linked below is a quick demonstration of the process, along with some tips on how to display and use this information via COGO point labels and exported text files for re-importation into the drawing or for using with other applications.
