The service ExpertGPS uses relies on premium data from the private data vendors, which means you get better results.īut the sad truth is that it takes a bit of time from when a new sub-division gets built out until the private data vendors actually get the street geocoded and into their subscription databases. But it’s free, which is why many geocoders use it. US census data is collected every 10 years, so it’s typically missing new developments. There are three main sources of US geocoding data: the US census, Navtech, and TeleAtlas. The Go to Address command in ExpertGPS queries an online geocoding service to try to turn the address you provide (in this case, 408 richfarm ct, lexington, sc 29072) into latitude and longitude. A look at the 2008 aerial photo in Google Maps shows that there are several new roads being constructed in that development – presumably that’s where Richfarm Ct is. I couldn’t find your address using ExpertGPS, and I couldn’t find it using Google Maps, either. How can I find the location of this newly-constructed road? (it is really off of richmond farm circle, which it plots correctly.) Is your source data outdated? I want to purchase your software, but I need to know the data will be current. It plots it with the incorrect coordinates about 5 mi NE of proper location. Select the data you want to send to your GPS, and click Send Selected to GPS on the GPS menu.I am trying to set up a waypoint for 408 richfarm ct, lexington, sc 29072. If you’ve already set ExpertGPS to use the same coordinate format, just click OK, and your data will be converted and displayed on the map in ExpertGPS. You’ll be prompted to confirm the projection and datum used in AutoCAD. Export your data from AutoCAD in DXF format, and click Import on the File menu in ExpertGPS. Sending AutoCAD layers back to your GPSĮxpertGPS Pro can send points or lines from your CAD drawings to your GPS, so you can check their accuracy in the field. Your waypoints will be reprojected to Northings and Eastings to match your CAD drawing’s coordinate system. At the bottom of the Export dialog, change the file type to AutoCAD. Otherwise, click on the map, and all of your waypoints and tracks will be exported. If you only want to export waypoints to DXF, click once in the Waypoint List on the left side of the screen. Connect your GPS (ExpertGPS supports hundreds of models from Garmin, Magellan, Lowrance, and others) via USB or serial cable, and click Receive from GPS on the GPS menu. The next step is to receive the waypoints from your GPS. ExpertGPS supports lat/lon, UTM, US State Plane, and most national grid coordinate systems. Follow the directions in this tutorial on how to add a new coordinate format to ExpertGPS. The first step in exporting your GPS waypoints to AutoCAD is to set the coordinate format and datum in ExpertGPS Pro to match the coordinate system you’re using in your CAD software. Could you please explain to me how to import waypoints from ExpertGPS into an auto cad drawing by simply pasting to coordinates if possible?
