Instead, what we want to do is click the blue ‘No Coordinate System Specified’ link and choose WGS84. By clicking the Advanced button in the Import dialog box, we would have noticed that there was no coordinate system specified.Įven here, it might have been tempting to choose Same as: Robinson to add it to the Robinson MAP View, but this would import the points exactly the same as before – all in one location in the middle of the map. In MAPublisher 9.4, there’s a new button on the Import dialog box that allows you to see more detailed information about files being imported. The other place where we could have avoided this error was right after setting up the CSV file for import. What we should have done here was to specify the coordinate system as WGS84. We specified Same as: Robinson, thinking this was the correct choice, but we had already determined during import that the CSV was in WGS84. When we dragged the point layer into the Robinson MAP View, the pop-up dialog box prompted that a coordinate system wasn’t specified. There are actually two places in the workflow where we could have avoided this common mistake. The data has moved, but it still doesn’t look like we were expecting. We want it to be in Robinson like the rest of the map so we’re going to leave the default setting of Same as: Robinson. We get a prompt saying that there isn’t any coordinate system information. The new layer has been added to a new MAP View, so let’s try dragging it into the Robinson MAP View with the world map. The data has been imported but the result isn’t what we expected. Great! Let’s click OK and add the large cities to the map. The default is Projected units, but we know the file uses WGS84, and can tell by the numbers in the column that the coordinates are in decimal degrees, so we’ll change the format to reflect this information and click OK.īack at the import window, we see the message ‘Data loaded successfully’. Setting up the import, the coordinate column settings are easy since we have an X_COLUMN and a Y_COLUMN, but we can’t forget to check that the format is correct. We’ll click the blue ‘Required settings are missing’ link to continue. After selecting the file for import, the MAPublisher Import dialog box helpfully notifies us that some required settings are missing. We know from our data source that the CSV uses the WGS84 coordinate system. We have a CSV file containing points for large cities that we’d like to add to the map. We’ll start with a world map in the Robinson projection. MAPUBLISHER 9.4 TORRENT HOW TOIn this example, we’re going to look at the common mistakes people make and how to avoid them. When you are importing data from this format, you first have to define the correct coordinate system. Some file types such as CSV can be used for GIS data but don’t contain coordinate system information. Have you ever imported data that doesn’t quite line up how you’d expect? It may be that you’ve fallen victim to a common workflow error when importing GIS data.
