The article above should give you some ideas of how you can use ExpertGPS and your spreadsheet software to convert just about any delimited text data to another GIS, CAD, or GPS format. Need help converting a GPS, GIS, or CAD file? From here, I can export to ESRI SHP, to AutoCAD DXF, or edit the created tracks in ExpertGPS to add attributes prior to saving in GPX or KML format. It worked – all of the data from Excel matches up perfectly with the color aerial photos underneath. Now I just select the entire column, copy, and paste into the map in ExpertGPS. I added the KML Header to the very first line of the new column, and added the KML Footer at the bottom row. IMPORTANT: KML puts longitude before latitude! Then I used the CONCATENATE function in Excel to build up a KML LineString Placemark for each row. I used the Text to Columns command (on the Data menu in OpenOffice Calc and Excel) to split the coordinates out into four new columns, as seen above. The line in the middle is what we want to create in Excel – one of these for each row in the CSV file. ![]() Let’s call the first line the KML Header and the third line the KML Footer. Basically, my strategy is to use the formulae in Excel to build up a KML file which I can then paste right into ExpertGPS. Whenever I see multiple coordinates on the same line, I stop thinking about the CSV import function in ExpertGPS (which expects a single point per line) and instead start thinking about Google Earth’s KML format. ![]() Each line is its own two-point line segment, and when plotted all together, they define a complete route. However, the data in the file above is in a strange format – each line contains two latitude/longitude coordinate pairs – a starting point and and ending point. This is an advanced tutorial, showing several strategies you can use to manipulate just about any data in Excel or your favorite spreadsheet program (I use the free OpenOffice Calc) to get it into a standard format that ExpertGPS can import, map, and convert to KML, SHP, and/or DXF.ĮxpertGPS can import CSV and text data directly – just copy and paste into either the Waypoint List or the Track List. Once imported to EXPERT GPS, can I add/edit attributes? How can I create KML or SHP files from here. I have whole bunch of files in csv (or excel) similar to the one attached.
