GeoData

[hardeeprai]

If this is not the right place to ask this question, please advise me where to post.

It might be difficult to answer queries about many workbenches in this forum. But I couldn't find a right forum, where I could post.

I tried "Geo Data" workbench to import OSM data and prepare a site.

From following dialogue box, how area is selected, is not clear. Can anyone explain meaning of:

0*2_4_6_8*#*2_4_

displayed in dialogue box.

It says:

Length of the square 0 to 4 km with default 0.5km

But I got rectangle.

The position in GeoData -> Create Houses, in which it is supposed to enter latitude and longitude of house, has no effect.

Is it right behaviour and is it a design feature?

There is still no use of these data. The idea was to have some "control objects" which map lat/lot coordinates to the origin of the 3D space. Then there will be a mapping of the houses to the right place. We will implement these features when we implement the stationing concept for the transportation workbench.

Yes you are right. The size of the downloaded area is nearly quadratic but depends on the position lat/lon
I made a fast hack ...

b1=b-bk/1113*10
l1=l-lk/713*10
b2=b+bk/1113*10
l2=l+lk/713*10
source='http://api.openstreetmap.org/api/0.6/ma ... ,'+str(b2)

Could not get you about the "quadratic".

I believe is equivalent to:

<q>
latitudinal distance along any meridian (exact)
latitudinal distance (in metres) = (decimal latitude A - decimal latitude B) * 111 120 m
longitudinal distance along an average parallel (approximation; the highest the difference of the two latitudes, the lowest is the precision)
longitudinal distance (in metres) ≈ (decimal longitude A - decimal longitude B) * cos(average latitude) * 111 120m

* [Source] https://wiki.openstreetmap.org/wiki/Pre ... to_decimal
</q>

It is OK, if size is approximate.

I was more curious to understand following:

0*2_4_6_8*#*2_4_

I have updated the osm GUI. Now you can also copy and paste URL from some map providers instead of only entering (latitude,longitude). You can give it a try. The source code is here:

Wow!

Thank you Suraj for making it more user friendly.

@microelly2

Please see it, and if you find it useful, include it in your code, so that users can get it via FreeCAD's addon manager.

@suraj perhaps make a PR to the geodata repo ?
