Microsoft released 125 mil building footprints for US

#3
Interesting, I was just about to ask for Building Footprints...
But unfortunately I would need them for Spain and Greece...

Are there already for these countries any Building Footprints, and if not, do you have an idea how do detect them from a simple orthophoto/satellite image, are there pre-defined python-scripts for ArcGIS out there?

EDIT: The 125 million Building Footprints also include various scripts. Can anyone even do something with it and could someone explain to me briefly how to create footprints with these scripts themselves?

I don't see any scripts on that Github page, where did you find them?

It seems they used complex AI algorithms with a training dataset to detect the buildings. Will not be something that can be easily done on other area.

I still hope to make scenProc more capable i this area, was working on that for a project in the US. However that might get less priority now this data is available :)

That script is a general toolkit for deep learning, so it won't detect buildings out of the box.

Hi Bill:

Microsoft's online imagery tile servers "VirtualEarth StreetMap" & "VirtualEarthSatellite" TileServers in SBuilderX ...are BING Maps online.

Also, "ArcGisImagery" TilerServer in SBuilderX ...is what became ESRI ArcGIS "World Imagery" online.


If you wish to use imagery sources not directly downloaded with the SBuilderX TileServer feature, try:

SBuilderX Menu > File > Add Map > From Disk

...if the file is a Geo-rectified *.BMP or GeoTIFF already in the required cartographic projection (Geographic / WGS84).


FYI: There are Satellite imagery Tile Server download utilities in GIS applications such as QGIS, and in ex: FS EarthTiles (aka "FSET").

Specific imagery file formats output from those can also be used in SBuilderX. :idea:

Man, Gary.. A lot of that went right over the top of my head...

## Me; Wouldnt that need to be on my disc?

## Me; I think I need to know where this is, if this is freeware imagery. Off to google this and track it down.

Two simple questions here;

Are ArcGISImagery 'and' (or) Virtual Earth Satellite 'open use'? Can I use these for projects that become payware? If you do not know, that is fine, I can go research it. Hoping you know right off if these are open-ware like Capernicus are.

Capernicus require a subscription for zoom levels over level 5 when downloading their data. (Thats what I read and understood. Perhaps they have a different way of doing things for just getting imagery which might be different then what I am understanding? )

ArcGISImagery is very nice. Good colors. I am very impressed.

Yes; by default SBuilderX looks for such files first in:

[SBuilderX install path]\Tools\Work

...but IIRC, it can be directed to browse elsewhere for files in the correct GIS projection.

These files can then be manually 'Calibrated' in SBuilderX if they do not already have a matching *.TXT Geo-referencing 'world' file

I edited my editing error in the post above from which you quoted that sentence. :laughing:


FYI: Both SDK Resample for compilation of imagery, and SDK SHP2VEC for compilation of vector source data, require source files to be in a format known as a 'cartographic projection', and which is referred to as Geographic (Lat-Lon) projection / WGS84 geoid or ellipsoid or datum ...aka (EPSG:4326) in GIS applications.

Some tile servers may offer imagery that is public domain and free to use for freeware and payware projects; most do not.

They are most often intended for use as background images over which custom objects may be created by the end user.

One must personally communicate with the licensor of the imagery that is made accessible via tile servers to determine terms of use, if those terms are not otherwise clearly stated on the website for the tile server web portal. :pushpin:

PS: ArcGISImagery terms of use:

Like Gary said most images sources can be used in either freeware or payware products. In general Google, Ms, etc license the images from different suppliers and you are not allowed to redistribute them.

If you are working on the US it might be USGS data is used, which in general can be redistributed. But you need to check the source of the images to be sure.

Interesting... Thanks Arno. I did find that the imagery used in Google was Capernicus and I asked Capernicus if it was possible to use their images and they said 'absolutely, except please mention us as the producer of the images'. I obtained them through Google, and they were from Capernicus and Google stated that they are Capernicus images.

I wonder if that is good enough to allow me to use them. Capernicus did give me permission. I do not want to mess up on permissions.
