Dear All ,
I have a roofs & footprint of each building, from this how i will create all the below mentioned attributes in Shape file (.shp).Please help and suggest.
1,Unique Feature ID
2,Reference Name – China
3,Building Area (m)
4,Building height Values (m): Max, Min, Mean, 75th and 25th percentile
5,Building Height will be orthometric (Mean Sea Level) and Above Ground Elevation (AGL)
6,Building attributes will be MSL_Ground, MSL_Min, MSL_Per25, MSL_Mean, MSL_Per75, MSL_Max, AGL_Min, AGL_Per25, AGL_Mean, AGL_Per75, AGL_Max, Shape_Length and Shape_Area
uploaded roofs
It looks like a lot of those attributes are already in the file, what exactly are you looking to calculate?
I'm assuming the elevations to be in relation to Mean Sea Level, in order to get the AGL ones as well you'll need to know what the ground level per building is. Depending on how your data is set up you could take the minimum elevation, otherwise you'll have to look for a source for the terrain.
In that we tried here, you no need to consider those attributes.
MSL and AGL you fix it your own value roughly for calculate the attributes.
I'm sorry, but I don't quite understand your question. Could you elaborate please?
