both, there is background mathematical equation, and the image must have a proper metadata from the vendor so the parameters needed for the mathematical calculation can be performed
Hey! Should there be a way to automate the process and get approximate heights for the buildings across the whole image or a subset of it? Please suggest if there's a way! Thanks :)
AFAIK Esri didnt open the details of the algorithm, They only hinted that its needs the imagery complete metadata and rpc information to make the image based measurement possible. Refer to this pro.arcgis.com/en/pro-app/latest/help/data/imagery/making-measurements-using-imagery.htm . Personally I also didnt check if image mensuration generally has been explained in the latest rs/gis textbooks, may be you can dig it by yourself
You can try orbview 3 satellite available for free from earthexplorer.usgs.gov, but it wil only covers the 2010's because the satellite has burnt in the atmosphere.
walk pode usar imagens do orbview 3, disponíveis gratuitamente em earthexplorer.usgs.gov, não consigo carregar dados de imagem porque isso violaria a licença de compra de dados do fornecedor
May be the imagery you are using didn't have the needed metadata, or the imagery metadata reading is not supported by arcgis. For example arcgis version 10.1 can't read worldview2 imagery because arcgis 10.1 has been released prior to worldview2 satellite launch

As now you find the height of the building using the shadow is by using any background code or just by using the image.

As far I know, there is not, the only way to get those information is using photogrammetry techniques
Ahh ok! Thanks :)
How do I know the formula that ArcGIS uses to calculate the height of an object?

@@GEO2004 Can I use this tool of ArcGIS for free?
Sure, but arcgis itself is not free
Kalo foto bangunannya tegak apa akurat pak
Ya tidak,kalau tegak kan sudah ortho
Eh tapi kalau belom ortho, tegak masih bisa, asal ada bayangannya
One question~ where could I get the satellite imagery with raster metadata info for free?
You can try orbview 3 satellite available for free from earthexplorer.usgs.gov, but it wil only covers the 2010's because the satellite has burnt in the atmosphere.
Hola!! puedes por favor subir los datos (la imagen) para asi poder hacer el ejercicio? Gracias

Bro How can we Extract the Building footprint from Lidar Data with ARCGIS DESKTOP. please suggest me.
interesting, I will try to dig it
I found this, nmflood.org/wp-content/uploads/2018/12/Lidar-Building-Footprint-Extraction-Tool-User-Guide.pdf , may be it will helps you
I tried your way and still the mensuration tools are not activated what should i do?

Arcgis is 10.8 and the image that i have is with the metadata and still doesn’t work I don’t know what to do ☹️
Which imagery?
@@GEO2004
Can I send it to you ? And you check it if it’s okay
Yes, mail me at mappingsince2004@gmail.com
Can you share with us this imagery data?
I am sorry, I cant share the data due to user license agreement restriction
@@GEO2004 no worries cheers
