Measure Building Height From Satellite Imagery Using ArcGIS Desktop

[@RounakGoel]

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 :)

[@GEO2004]

As far I know, there is not, the only way to get those information is using photogrammetry techniques

[@RounakGoel]

Ahh ok! Thanks :)

[@charanabburi4088]

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

[@GEO2004]

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

[@khangminh5594]

How do I know the formula that ArcGIS uses to calculate the height of an object?

[@GEO2004]

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

@@GEO2004 Can I use this tool of ArcGIS for free?

[@GEO2004]

Sure, but arcgis itself is not free

Hola!! puedes por favor subir los datos (la imagen) para asi poder hacer el ejercicio? Gracias

[@GEO2004]

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

Bro How can we Extract the Building footprint from Lidar Data with ARCGIS DESKTOP. please suggest me.

[@GEO2004]

interesting, I will try to dig it

[@GEO2004]

I found this, nmflood.org/wp-content/uploads/2018/12/Lidar-Building-Footprint-Extraction-Tool-User-Guide.pdf , may be it will helps you

[@王思-o9u]

One question~ where could I get the satellite imagery with raster metadata info for free?

[@GEO2004]

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.

Kalo foto bangunannya tegak apa akurat pak

[@GEO2004]

Ya tidak,kalau tegak kan sudah ortho

[@GEO2004]

Eh tapi kalau belom ortho, tegak masih bisa, asal ada bayangannya

[@noormajid4591]

I tried your way and still the mensuration tools are not activated what should i do?

[@GEO2004]

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

@@GEO2004 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?

Can you share with us this imagery data?
