whether you start with lat/longs or northing/easting, whether your point list is. By uploading, you will reveal your points, I.e. To get the points to be consistent with Google Earth, you must disclose more info or upload your list, or partial 10% list, of the points you wish to insert. Likewise, why would you use a script to insert a list of points when Map 3D has a built in function to do it for you? You wouldn't use a script that I wrote, or anyone else wrote to draw a circle, would you? I think you'd rather use the built in circle command. If you still want to use blocks and not points, it still can be done of course without using a scrip because Map 3D will insert the blocks for you, it's just simpler to insert points especially when you don't need to label the blocks. I can only think of two reasons you would use blocks: if you need to use the block attributes for labels or if you need to perform data extraction on the blocks once they're inserted. You should simply insert points to represent points, not blocks. You are using Map 3D (or Civil 3D) and you are inserting blocks which represent 3,000+ points. Also your drawing should display 6 decimals for meters-you attached images only show 4 and you need to fix that. Cad locations looks like it is due to not enough decimal places when you enter the lat/longs. The difference between Google Earth locations vs. If lat/long in #7 above is deg-min-sec, then enter LATLONGFORMAT and change it to "0" for decimal degrees.It doesn't matter whether you use imperial-feet or metric-meters template.With marker still selected, scroll to bottom of properties and view lat/long in location section.Click the marker and view Position X and Y in geometry section of properties.Select that newly created marker and make it bigger by increasing size in Properties Palette. Type SITE for the label, then click an empty area in modelspace to end command (don't hit enter).Go to Geolocation tab=>Tools panel=>Mark Position icon=>then choose Lat-Long from button's dropdown.Alternatively, use UTM84-19N (meters), EPSG 32619, using a metric template. Assign Massachusetts State Plane MA83F (US feet), EPSG 2249, using an Imperial template.To make this work for you, open a blank template and do this: Is UTM-zone 19 ever mentioned? Cad knows lat/long but he doesn't know you need UTM-19 easting and northing. The workflow is going backwards and Cad simply doesn't have enough info to do it in reverse. Projected UTMs of easting and northing in step 4 which you created from your mouse click.Geographic lat/long's you entered in step 1.Instinct tells us it should match, but it doesn't. Cad has indeed forced that 'clicked spot' to correspond to the lat/long of your pin, but it won't necessarily force your clicked spot to correspond to UTM meters shown in the Google image (it forced the x-meters and y-meters to your clicked spot, not the true easting/northing). Review your workflow and you'll see that in step 4 you instructed Cad to put the pin (the Bing Imagery) at the location of your mouse click. The reason they don't match is because the easting and northing coordinates shown in your Google image is referenced to UTM (Universal Transverse Mercator) zone 19 and the coordinates shown in the Cad image, the numbers at the bottom, are referenced to an arbitrary spot that you clicked with your mouse. If you want to match Google Earth's projection, then I'd recommend the WGS ellipsoid referenced to UTM84 zone 19north (meters). I would recommend a projection using Massachusetts State Plane, specifically Massachusetts Mainland (US-feet), EPSG 2249. What I'm doing wrong? Here are some images: The problem comes when I compare the coordinates in Autocad A visualĬheck of the location of the Marker on the map in Autocad and Google Earth shows that Then Autocad places a Marker on the drawing and the map that appears below. When Iĭo that the map show the same point as in Google Earth.ģ- I click "Next" and select a Coordinate System (WORLD-MERCATOR / WGS84 / Meter).Ĥ- I select a point in the drawing that correspond to the reference point in Google EarthĪnd use ortho to indicate the north direction. I want that it matches with Google Earth coordinate system.ġ- Get the lat/lon of a reference point (42.539081 / -70.941904) in Google Earth.Ģ- In Autocad click Insert>Set Location and drop a pin at the above point.
