Got height is a difficualt things, GeoData Workbench/Geomatice Workbench/Trails Workbench gots errors.

[freecadlzh]

To now I tested three workbench, got height data goes errors all, The resualt list below:

1.Geo data workbench gots errors:

2.Geomatics workbench gots errors:

3. Trails workbench gots errors:

In the three workbench, I used the defalt location, And got errors all.

Now I have no way to got the height , It is a difficault things to me.

But some videos in youtube, some teachers use freecad(geo data workbench, geomatics workbench) got the height is so easy, Why it is such difficault to me? Is there some still ?

Need suggestions , Thanks a lot.

After trying, even if I'm already logged in map.google.com However, the above error still exists, and the elevation data cannot be loaded.

Google Maps height api is not supported anymore. bernd said he working on it.

thanks for the reminder ... https://forum.freecadweb.org/viewtopic. ... 09#p431609 for reference.

Is there any progress?

Sorry, perhaps I got a wrong idea.

Above I still think the data is got form map.google.com, but when I learn the source code, I find it is not true:

In import_heights.py sourcecode the line 28 code is :

Code: Select all

def getheight(b,l):
	source="https://api.open-elevation.com/api/v1/lookup?locations="+str(b)+','+str(l)
	FreeCAD.Console.PrintMessage("\n" + "lzh height source is:" + source + "\n")
	say(source)
	print (source)

when the prog runs, I printed the string var "source" and got the data:

Code: Select all

lzh height source is:https://api.open-elevation.com/api/v1/lookup?locations=50.3377879,11.210409616:27:38 

So I think the import_height.py got the height not from map.google.com, just got data from web https://api.open-elevation.com.

Then I tried the url "https://api.open-elevation.com/api/v1/l ... 9616:27:38 " in my browser then got the result:
502 Bad Gateway
nginx/1.13.5


Then I tried import_srtm.py source code line 117:

Code: Select all

def getdata(directory,dat):

	zipfilename=directory + "/{}.osm.zip".format(dat)
	source="http://geoweb.hft-stuttgart.de/SRTM/srtm_as_osm/{}.osm.zip".format(dat)
	FreeCAD.Console.PrintMessage("\n" + "lzh srtm source is:" + source + "\n")
	fn=directory+"/"+dat+".osm"
	if not os.path.exists(fn):

When prog runs, I printed the string var "source" and got the data:

Code: Select all

lzh srtm source is:http://geoweb.hft-stuttgart.de/SRTM/srtm_as_osm/Lat45Lon2Lat46Lon3.osm.zip

So I think the import_srtm.py got the SRTM data not from map.google.com, just got the data from web http://geoweb.hft-stuttgart.de.

Then I tried the url "http://geoweb.hft-stuttgart.de/SRTM/srt ... n3.osm.zip" in my browser, and got the error, can not got the file by my browser.

So, Is the url in sourcecode "import_heights.py" and "import_srtm.py" should be changed to map.google.com? How to change the code?

Need help, Thanks a lot.

PS: The source code above just from Trials workbench source code !

You need to wait a little bit

https://forum.freecadweb.org/viewtopic. ... 50#p441701

[bernd]

to make it simpler to wait ...

https://forum.freecadweb.org/viewtopic.php?f=24&t=49575

I have spent some time on this. I have something which works for me on Linux, but i did change a lot in import_osm and did tried a lot services to get the heights. If we would just merge all it would be impossible to track it. I started to make a PR.

[bernd]

if you can not wait try the module attached ... You need to have trails installed, but the one with my PR from https://github.com/joelgraff/freecad.trails/pull/62

This geoosm modul only has one tool, the import osm, but it works with heights. See module get_elevation for a lot of remarks ...

Thanks for your help, and thanks for your efforts.

I download the file "geoosm.tar.gz", extract to my mod folder and run the prog, The geoosm workbench can runs, I set the location same to your sample and got the result below:

As the pic shown above, I can find the map model loaded and the height loaded is "0" , seems not get the DEM data.

PS: As my place is in china, so I did opened a “Wall climbing software” .

My questions are:

1. I think there is somthing wrong, Pleas give me some suggestion.

2. And, Will your newly released geosm be on your GitHub? If so, please provide the GitHub address.If you make any changes, do I have ne on GitHub？

[bernd]

It seams you are on windows. As I wrote before. It only works on Linux out of the box. If you are on Linux you need to indtall the missing module.

For more infirmations see the duzens of comments in get_elevation module.

This is exactly the reason we can not just merge it, because it does work only some cases out of the box.

[bernd]

As soon as it is improved I will go for a PR to trails.

At the moment this is not on a github, as it only has been dome haack to get it working for my purpose. I may put it on github anyway ...
