How to create a TOPO STL File
Vložit

- If you are like me you think of an idea and have to figure out how to do it!! Here I walk you through the process of creating a TOPO STL File from government Topographical data.
I partnered up with @myerswoodshop to make an awesome gift for my brother. He took the file and cut it on his Onefinity CNC.
Make sure to watch his video which shows how to make the stl file into a 3d carved gift!!

I am just staring to watch this, thanks for sharing by the way, but believe the folder chose on Mr. Rowntree's site, the "one that ends in a 4", is actually the oldest folder. His folder naming convention is the year, month, and day so that folder ending in a '4' is from March 4th, 2013. The folder ending in a '3', would be the newest being August 3rd, 2016.
I have not looked at the full contents of the folders but can see that the folder ending with the '4' has only file dates of 2013 while the folder ending with the '3' has files from 2016.
@@daveyoung3965 Thanks for sharing I did not catch that. The documentation that I saw said to use the file on the video due to it having the BIGTOPO application!
Thank you for the easy to understand instructions! I can’t wait to try it!
Sorry to report that Professor Paul Rountree passed away 7/27/2020. Dr. Rountree wrote the software you used to create the STL file.
Awww so sad.
I tried this today and is was 404 error
Awesome.
Anyone else have problems with the USGS link for the SRTM data not working?
Has anyone found where the new data went to? I found tons of STRM data, but nothing in the LAT/LONG format that Rowntree used.
Im having a hard time finding the coordinates for the middle east in the files provided. Can anyone help?
Question-- can you import fictional map and extrapolate it into working topo file?
Thank you
This is awesome, Peter! I went to school for geography and my day job is a GIS Analyst (I make maps and manage geographic data). This combines that with my love of woodworking, so I am completely nerded out right now. 😂 I can't wait to get my OneFinity and start cranking out topos. Excellent explanation and tutorial of the process. It was very straightforward and easy to understand, even though I don't have a CNC (yet!). Just subbed and looking forward to checking out other videos and products you come up with. Thanks! - Joe
You are welcome! Stuff has changed but the info is still out there. Here is what another user has done
Get SRTM files from here dwtkns.com/srtm30m/ you will need to register for a username on nasa earthdata urs.earthdata.nasa.gov/users/new (free) and login before getting any file. Then just put the files from the tiles you are interested in into a directory called C:\Topo 20160803\SRTM_3 if you put the topo zipfile under c:\ for example. Load topo.exe and load the unzipped hgt file from the button up top and place your mouse on the northwesternmost position you want to start. You can then enter that position you see in status bar of topo.exe into bigtopo.exe. Do the same process to get the southeasternmost point, and then work in bigtopo. Good luck, took me a while to be able to do it. The most important part is that you download all files for the tiles you are interested in and put them in the directory mentioned above.
@@RowdyRoman Thanks so much for the updated info!! If I remember correctly, you used Vetric Aspire, right? Do you know if this will this work in Vcarve Pro as well?
@@cobaltwoodcraft4365 ummm I think so but can’t remember 100%
@@peterromano6905 Okay, thanks Peter!
It appears you have to apply for login credentials to access the USGS files now.
Thank you for the video . I was hoping to do something like this for my dad. We go to canada fishing each year, but apparently with not much elevation change it doesnt work so well. Cant seem to get anything usable.
You are correct if it is flat it will only be bumps and not look right. There definitely needs to be some elevation change
@ryan LaBarre for a small area check out jthatch.com/Terrain2STL/
@@RowdyRoman thank you, ill check it out
I've tried this, but it seems as though the link where the topo maps are supposed to be, is no longer valid. Do you know if there is a new link? Thanks!
Same. I tried searching for other downloads, but completely clueless of what I'm looking for.
@@zigmo716 thingiverse has several topo files available
Do you think this could be done with foam instead of wood? Trying to think of something lighter than wood that could cover afterwards
Sure thing Kari! You will want to use high density foam!
What vertical exaggeration factor did you use for Ketchikan? Great Project! Thanks for sharing!
Man I don’t remember but if I had to guess it was around 2????
@rowdyroman Following this to a T and get a barely visible Topographic rendering. Does this mean the area isn't high enough above sea level to spit out a model? Tried messing with other settings and not having any luck..
@eric M That is a possibility. Are you working with the US?
@@RowdyRoman Yes particularly the great lakes, Lake Erie. I was able to download manually each individual .hgt file and am currently in the process of separating them manually and saving to the SRTM_1 Folder because im also not having luck when the software attempts to download them.
@@ericm1330 Yes I never used the software to download them. Email me at rowdyromanfire@gmail.com and I will send you the stl i come up with
Enjoyed the video, and took me down a rabbit hole of learning. Come to find out I can't get access to that SRTM site, gives me a 404 error. Roman wondering if you had any issues or if anyone else had encountered the same?
Hey Brian you are correct. I just found out that the government is switching to another file. I have not found out the location yet. However if you are trying to do stuff within the U.S. you can use Jhl terrain
@@RowdyRoman Thanks for the quick reply, I was thinking it was user error! I'll keep my eye open as well and let you know if I find the next location. I'd guess we'd have to manually drop the STRM files in those sub folders in order to keep the program working.
@@bnakoneczny Yup we would just download them and drop them in the folders. I am in contact with a company that is letting me use their program which uses Linar data so that will start next month. The downside to that is it only does small areas like 100 Sq miles
Same issue here. I'll be on the lookout for a dataset.
Any idea how to get the correct elevation data. The links dont work anymore. Thanks for any help
This should help

What do you do if you are doing an inland area for elevation?
Andrew Try this website. It is a whole lot easier to work with.

If you don't make a donation do you get the same files? I was going to make a donation based on how well it worked but nothing looks like it does on you video when I did the downloaded.
I am not sure I did not make the donation. However, the documents state that if you do it gets rid of the beginning screen when you load the application
Thanks for the tutorial! One question, did you download each of the STRM files 1 by 1 or is there a faster way?
Marc I did have to download them individually. However, If you are doing a small area you can check out jthatch.com/Terrain2STL/
@@RowdyRoman Thanks! I don't mind downloading the files, it doesn't take that long for each. What is in the DEM folder?
@@marcm6109 BigTopo can read SRTM-1 and SRTM-3 files (like Topo), but it can also read files created by the program DEM_2_SRTM, which are lower resolution (1 km data spacing) but can be downloaded much easier in large blocks via DEM files. Each DEM file contains the equivalent area of 2000 SRTM-1 (or SRTM-3) files. Downloading standard SRTM files one-at-a-time gets tiresome very quickly. DEM_2_SRTM and its manual are included in the download package with Topo and BigTopo. DEM files are freely available at the above mentioned web site.
@@RowdyRoman that’s for the quick replies and help! Now I gotta get started on this last minute Christmas gift. Haha
I used wget in a cygwin install to do a recursive loop to get them all, easy peasy.
I have just D/L it and there are no directory folders. There are only4 application files, 4 adobe docs, 1X 3D object and 1 HGT file. Advise please..
@iaidoman I am not sure! Try redownloading it and unzipping it
They don't come with the stock SRTM folders or a DEM folder, you have to make them yourself, and then pull the USGS data to populate at least the SRTM folders, I think the DEM is of what you choose to do more with the topo program.
Am i dumb? i can't find where to download the SRTM files. the link on the website and the PDF doesn't work.
There is a link on the website where you downloaded the program or you can just google search for the files
I know I’m late to the game but I just tried to follow this video. I have searched high and low but I cannot for the life of me find the srtm files. The link on the website comes up as error for the usgs site. I know you mentioned that there are several ways to get the data but I have struggled to get the info. The best I have been able to do is use the touchterrain site which works great except I wanted to pour resin for the ocean I’m looking at jonesport me area. I have looked at everything I can find and as far as I can tell I can’t get the touchterrian site to give me extra depth to pour the ocean with the resin. Anyone have any tips or ideas would be appreciated thanks
No worries Sam here is how others are getting the data now

Easier said than done. All the links to register are broken. Ive emailed for help, waiting for response
Hi - I know it's been over 2.5 years since you did this video but I thought I'd ask... it looks like the USGS has changed their site and the page where the data files referred to is dead. Do you have a new way of obtaining topo data that's similar to using Big Topo or downloading it directly somewhere? I found where you can submit a request for the USGS to send you a topo map, once you select the parameters, but then you have to wait 1-5 days for them to email it. And I've tried a couple of sites that let you build a map, but I haven't found anything a succinct as this process. Are you doing this a new way now? Thanks!
Here is where another subscriber figured out how to get the data

@@RowdyRoman Thanks - I cannot figure it out. I think I'll give up now. ☺
How do you fix the "out of memory" error?
I had that problem too. I just restarted the program and it worked
The link doesn’t work to pull the Dem and SRMT files. Any suggestion?
I am working on another way to pull the files
@@RowdyRoman any luck? Awesome video, but not sure how to get the data, now that the USGS isn't working! Want to do the State of MO for a friend.
looks like all maps have been moved to here: apps.nationalmap.gov/ but, I am not sure what data to look for, there is mention of DEM, but not of SRTM... How big are the files that you downloaded? are they shareable?
Anyone else getting an "A 404 Error Occured Page not found" when you try and click the link in the PDF file
Yes! I am having an awful time trying to find useful SRTM files anywhere. I've been looking for a few hours.
@@ehofstadter bummer. I wish topography was easy as google search the lake name.stl lol
I don't see your video is of any used to anybody anymore, the website is down and the new page you mention can't do what you did, lower the water level so you can used resin, sure you can create a 3d map. What a waste of time.
You could hack in some pockets for vectric to lower things for water fill.
I can't find the The elevation data files for download: this link DOES NOT work: dds.cr.usgs.gov/srtm/version2_1/
any suggestions ?
Hey Bernard. Sorry to say they took down the website to get the files. Recently I have been using the following site. jthatch.com/Terrain2STL It is a lot easier to use, but has some limitations
@@RowdyRoman Do you have a video on how to download data from this new place so big topo can use?
