Once the process has run, you can examine the added information by right clicking on your data layer and selecting”Load Attributes” (if loaded into ArcMap) or by selecting the layer in ArcCatalog and clicking on the preview tab and then selecting “table” as the viewing option.Īppending to the last columns of your attribute field will be three fields: Point_X (containing the X coordinates), Point)_Y (containing the Y coordinates), and Point_Z (usually empty unless the data set is enabled with elevation (z) values). Depending on the size of your GIS data file, this process will take anywhere from a few seconds to a few minutes. In the lower right hand corner of ArcMap or ArcCatalog, the status of the process will show. Then hit the “OK” button to start the process. Otherwise, if you need to load the layer or are accessing the tool from ArcCatalog, then select the folder icon and navigate to the directory on your computer or server where the GIS dataset is stored. If you are working in ArcMap and have the data layer already loaded, then select the layer from the drop down list. This will bring up the Add XY Coordinates window. Finally, click on the “Add XY Coordinates” tool. Then click on the “+” sign to the left of the “Features” toolset. You can add data to an existing table by pasting values from other applications such as Microsoft Excel. There are several ways to add data to tables. First click on the “+” sign to the left of the “Data Management Tools” to open up the options. Adding data to an existing table and editing that data in the table are important parts of maintaining a current and complete GIS. Next, navigate through the options in the ArcToolbox window. From the toolbar, select the ArcToolbox icon to pull up the ArcToolbox window. How to Add XY Coordinates to the Attributes for a GIS Datasetįirst, load up an instance of ArcMap or ArcCatalog. The tool used in ArcGIS to add coordinate values is called “Add XY Coordinates” and can be found in the ArcToolbox. the tool used in arcgis to add coordinate values is called add xy coordinates and can be found in the arctoolbox. Outlined in this article are the steps to take in order to add X Y coordinates to a field in the attribute table. I’ve always managed to add lat, long coordinates, but it takes a bit of trial and error to know which rows or records are giving you the headache.If you are using Esri’s ArcGIS GIS software program, there is a simple way to add coordinate information to the attribute table of a GIS data set. If this doesn’t work, then check the coordinate system again. Switch the test data tab with the one record with those coordinates from notepad. If this doesn’t work, zoom to your location where you think the data should go… Write those XY coordinates down in notepad. Again, follow my tutorial and see if that works. Copy and paste the values (so no formulas) for the header and first row only. If you do have data, and coordinates appear in the wrong location… Try to use just one row of test data. For most computers this can be done by going to Start>Programs>ArcGIS 10.2>ArcMap 10.2. When you add the table to ArcMap in the table of contents, when you right-click and open attributes does it have data? If nothing, then this means that one of your columns might have a symbol, or something. If the data is in lat, long then is it being set to WGS or the correct coordinate system? If they are in the wrong location, is there supposed to be a negative symbol for the coordinates that are in decimal degrees.Ĭheck for if there are spaces at the start of a coordinate.
