Choose type KML, give your file a name, and click Save. Open Surfer Open Wateshed.srf from the Samples directory. Now let s try the same thing in Surfer 12. Other programs, like Google Earth, will interpret these as latitude/longitude coordinates, placing the map in Africa instead of Colorado.Ĥ The map shows up in Africa in Google Earth because the page coordinate units are taken as lat/lon values. If you click OK in this dialog, you map will export in the units shown under the File Rectangle (page units). That is why the File Rectangle and Page Rectangle units match in the Export Options dialog.
Surfer 12 export 3d files how to#
They re in page units because Surfer doesn t know how to reference the non-map object in map units, so it puts everything into page units.ģ Because the non-map object is in page coordinates, the entire map will export in page coordinates. This is because they re in page units, inches in this case.
In the Export Options dialog you ll notice that the File Rectangle units match the Page Rectangle units, and they don t match the extents of the map. In the Export dialog, set the Save as type to KML Google Earth KML (*.kml), give your file a name, and click Save. The Map frame and everything inside are map objects.Ģ The map objects are listed under the Map object in the Property Manager. The Text object is outside of the Map object so it is a non-map object. You ll notice that there s still a Text object visible. Collapse the Map object in the Object Manager by clicking on the minus sign next to it. The coordinate extents of the map can be seen in the Limits tab of the Property Manager. These are latitude and longitude coordinates for an area in Colorado, United States. By clicking on the Map in the Object Manager and then the Limits tab in the Property Manager, we can see that the limits of the map are to in the x direction and 39 to 41 in the y direction. To illustrate this, let s compare the process in both Surfer 11 and Surfer 12. Surfer 12 has added the option though to export map and non-map objects in map coordinates on the very first export in only a few steps. In Surfer 11 and earlier, if you had a combination of map and non-map objects that you wanted to export to map coordinates so your KML or DXF file would be properly georeferenced, you had to perform a double-export workaround, detailed in the Newsletter 48 article Converting Drawn Objects from Page Coordinates to Map Coordinates. Everything outside of the map frame (non-map objects like color scales and drawn objects) are stored in page coordinates. objects within the map frame, are stored in map coordinates. If the drawing does not have a coordinate zone assigned, you must specify one.1 Surfer 12: Export Map and Non-Map Objects with Georeferencing Surfer keeps track of objects using two separate systems: map coordinates and page coordinates. The exported DEM file inherits the coordinate zone assigned to the drawing. The surface data is imported to a DEM file in the location that you specified. Specify if you’d like to use the default null elevation or specify a custom value and enter the value.In the Export Surface to DEM dialog box, under Export, add information on the exported file, such as DEM file name, coordinate system, grid spacing, and elevation.If more than one surface is available in the drawing, and you have not selected the surface in the previous step, in the drawing, click the surface which you want to export.Click Surface tab Surface Tools panel Export To DEM Find. Open a drawing with surfaces that you want to export to DEM.You can export all types of AutoCAD Civil 3D surfaces, including terrain and volume surfaces. You can export surface data to a DEM file and use the surface in other applications that support DEM data files.
