How To Extract Points From Tin

13-12-2011· Edit Iterate Datasets so the Dataset Type parameter is set to "TIN" [ATTACH=CONFIG]26769 [/ATTACH] Add the "Add Surface Information" tool, specify the input points, select the Z property, and set the "TIN" output from Iterate Datasets to the Surface parameter [ATTACH=CONFIG]26770 [/ATTACH]

I have a TIN file that was built off of contour polyline shapefile (I think). I have a point shapefile with a few points. How can I extract elevation of the TIN file where the points occur? I am using ArcMap with python automation. Any free software would be welcome as well. Perhaps a transforming of the TIN to another file type is needed.

01-06-2013· If you need a point file which includes all of the edited surface TIN points then extracting them from the surface, converting the ACad points to C3D cogo points and then exporting those is likely your best option. EDIT - Jeff's solution is better if you just want a simple csv file. 05-31-2013 09:12 PM.

Extraction of Tin/ Stannum Extraction of tin consists of three parts, i.e. tin ore concentration, smelting and refining. Cassiterite is the main source of tin ore, with specific gravity of 6.8-7g/cm 3, density larger than most of gangue. Therefore, 90% of tin concentrate is mainly obtained from cassiterite through gravity separation.

05-05-2016· How To: Extract Z values of a TIN or raster layer to a point shapefile Summary. Instructions provided are steps to extract Z values from 3D data and write it into a point shapefile attribute table. Procedure. The shapefile must have 3D point features. Following these steps to add Z values to the data:

12-06-2018· Top Replies Offline Beebe Ray Wed, Jun 13 2018 8:47 AM +1 verified The extract graphics tool is what you would use to extract points as a SPOT feature and create a .DAT file then create a .TIN file. If you use the element information tool you will see the X,Y,Z location...

08-03-2018· I do not have the pnts file therefore I attempted to export the points as a pnts file format into the same directory as the tin file, but this did not work. Second thing, the surface I created using the points and matching to the polyline

You can create a TIN surface from features, such as points, lines, and polygons, that contain elevation information. Create a TIN. To create an empty TIN follow these steps. On the Analysis tab, click the Tools button . The Geoprocessing pane appears.

Converting TIN surfaces to features. Available with 3D Analyst license. Triangulated irregular network (TIN) components, such as nodes, edges, and triangles, can be converted to points, lines, and polygons.

Importing a TIN file creates a surface object on which you can perform all the standard data operations and editing. The import operation is displayed as the operation type Import Surface. See About the Surface Definition. You can use this command to import a TIN file from an Autodesk Land Desktop project. To import the TIN file, the accompanying PNT point file must

Select "Create AutoCAD 3D Solids from the list. A dialog box opens which guides you throught the creation process: In older Versions of Civil 3D you need to follow these steps for 3D solid creation of a surface: Have your Surface style display Triangles. Use the _AeccSurfaceExtractObjects command in order to extract the Triangles and obtain 3D,

All Answers (5) In QGIS you can use the 'Point sampling tool' plugin, or in ArcGIS you can use 'Extract values to points' from the spatial analyst tool

21-09-2007· 1) Select a surface style that displays points. Surface points, that is. 2) Under the surface menu, select Utilities>Extract Objects from. Surface. Deselect everything but Points, and make sure "SELECT ALL" is. chosen. 3) For better visual clarity, I isolated the points - they are AutoCAD. points.

TIN surfaces generally take longer to build and require more disk space than grid surfaces. When Autodesk Civil 3D creates a TIN surface from point data, it computes the Delaunay triangulation of the points. With Delaunay triangulation, no point lies inside the circle determined by the vertices of any triangle.

09-12-2013· So, I discovered the trick is to use a combination of the Polygon class methods to achieve this.. If you want geodesic coordinates, you then need to transform these back to WGS84 (via pyproj, matplotlib's basemap, or something).. from shapely.geometry import Polygon #Create polygon from lists of points x = [list of x vals] y = [list of y vals] some_poly

TIN. Thinning Type. (Optional) Specifies the technique to be used to select a subset of LAS data points that will be exported to TIN. No Thinning —No thinning is applied. This is the default. Random —LAS data points are randomly selected based on the corresponding Thinning Method selection and Thinning Value entry.
