Mono-Image Height Extraction Algorithm (MIHEA) MIHEA is a software package developed for the purpose of extracting structural information from single high-resolution satellite images. This software is designed to work with several optical satellite platforms such as: QuickBird, IKONOS and Orbview. Critical structural and spatial attributes- important for earthquake loss estimation- such as longitude, latitude, height, number of stories, total square footage, roof perimeter, façade area and degree of irregularity are among the attributes that MIHEA calculates. Results are reported in the form of spreadsheet tables (.xls), GIS compatible shape files (.shp) as well as Google Earth .kmz files. An extension of MIHEA for using quasi-stereo images (combination of single satellite images from different platforms) is under development. This software package is capable of using multiple (two or more) satellite images from different platforms to create 3D city models. |
