![]() Export the converted image or boundary file to a new file.In the Contents window, uncheck the four axes ( Right Axis, Left Axis, Top Axis, Bottom Axis).The map on the screen is converted to the new coordinate system.Ĭhange the coordinate system of the map to convert the base map data. In the Assign Coordinate System dialog, select the coordinate system you want to convert the image or vector file into.Now the map can be converted into the new coordinate system.In the Assign Coordinate System dialog, select the coordinate system of the imported file.If not, and the Name says Unreferenced local system, then you will need to manually specify the file’s current coordinate system. If the existing coordinate system is already listed, you can skip to step 3. you have a georeferenced image file or a PRJ projection information file), this information is automatically entered. The original coordinate system must be specified.In the Properties window, click the Coordinate System tab.In the Contents window, select the Base layer.Verify that the original, source coordinate system is defined for the Base layer.The base map is created.Ĭreate a base map from the file in the original coordinate system. Click Home | New Map | Base, select the vector or image file and click Open. ![]() You can also convert the coordinate system of any base map file, such as vector files and image files. Click File | Save to save the data file for future use, and File | Close to close it.The source data is converted to the target coordinate system in the specified columns. The target columns are populated with the converted data. Set the source data columns and coordinate system, and specify theĬoordinate system and columns for the converted data. In the Assign Coordinate System dialog, select the coordinate system you want to convert the data to and click OK.Click the (…) button to the right of Target Coordinate System.By default, the first two empty columns are selected. These must be different than the original source columns. These are the columns in which you want the converted data to be stored. Specify the Target Columns for X and Y.In the Assign Coordinate System dialog, select the current coordinate system of the data and click OK.Click the (…) button to the right of Source Coordinate System.These are the columns in which the original X and Y data are located. Specify the Source Columns for X and Y.In the New Projected Coordinates dialog, you must tell Surfer what columns are to be converted, what coordinate system the data is currently in, and what coordinate system you want the data to be in.Click Data | Coordinate System | New Projected Coordinates.Click File | Open in Worksheet, select the data file and click Open.You can convert the coordinate system of raw data using the Surfer worksheet. See the outlines below the exact steps to follow to convert the coordinate system of four different types of file formats: from geographic lat/long to UTM) for a variety of reasons, such as calculating volumes in specific units or for use in other software packages that do not support coordinate systems. projection and datum) of any supported file format! You may want to convert the coordinate system of data, image, vector or grid files (e.g. Surfer can easily convert the coordinate system (e.g.
