Hello !!
I tried to create topography from excel file and .txt file but its not making. I am gonna share both files if you can help me whats wrong with it.
i used the method massing and site > toposurface > create from import > specify points file
sorry i just saw its making but very minute and irregular i dont know why . i took topography data from google earth. and by TCX Convertor gave it altitude and saved as excel file.
The values are points that are nearly the "same", they only vary in the 3rd-4th decimal point values. That's a pretty "small" site if those values are correct.

It's making it. All 239 points are placed. But your x and y values are all in the same relative position 50 and 11.

Pretty mountainous too. he,he.
yes its actually a very small site but still it should give a correct regular shape
yes its a small site but not too mountanious. how to u get such shape as i get a long narrow shape and at both ends a little topography haha
What I mean is that EVERY point coordinate is at x=50.964, y=11.331 (or 11.332), z=236. So basically, all the points are on top of each other. The point coordinates only differ from one another by 1/10,000ths of a "unit". Here's the resulting Toposurface if you remove those first 5 digits of every x and y coordinate in the point file. I'm not advocating you truncate each line; I'm just illustrating my "point". Pun intended. The resulting Toposurface has a Projected Surface Area of 428804.00 sq. "units". Depending on the unit of measurement it could be a Continent or it could be a heel imprint in the mud. Don't know. But it's definitely a Revit Toposurface.
Actually i captured a small place around 270 square meter in google earth and produced this csv file using TCX Convertor . Is there any fault in my procedure of getting this excel file as all points are overlapping or Google earth is not giving accurate results.
hey i want to take any area from google earth pro and then convert its data in form of excel file and then use this excel file to make topography in Revit . But as u know my points are somewhat coinciding when making topography . is somewhat wrong with my method ? can u have a look
Is it here? I think they are longitude and latitude, and elevation in meters, maybe.
yes here was the area i wanted to take data of. My revit file is in meters where i have to feed this topography . actually elevation data is important for me as i have to test which building out several could possibly fit on which topography
but i captured the area from google earth pro . i dont know how x and y values are almost same . is something wrong with my method ?
I think the x and y Are latitude and longitude. According to Wikipedia , 1 degree of latitude equals 110.6km and 1 degree of longitude equals 111.3km at sea level.
https://en.m.wikipedia.org/wiki/Lat-lon
So for example if there are 2 points share a same latitude and a difference of 0.000005 in longitude, the actual distance between will be about 0.000005*111300=0.5565m
Just googled it. ![]()
Try the Dynamaps maybe. It can create the topography, buildings, roads etc. for you and the only thing you need to do is typing in the address.
