Temporal and spatial resolution requirements for extracting
urban/suburban infrastructure and socio-economic attributes
from remote sen.& data are presented. The goal is to relate
the user information requirements with the current and proposed
remote sensing systems to determine if there are substantive
gaps in capability. Several remote sensing systems
currently provide some of the desired urban/suburban infrastructure
and socio-economic information when the required
spatial resolution is poorer than 4 by 4 m and the temporal
resolution is between 1 and 55 days (e.g., Landsat MSS and
Thematic Mapper, SPOTI-4, Russian TK-350, RADARSAT, Indian
IRS-ICD, NOAA AVHRR, GOES, Meteosat). Current high
spatial resolution sensor systems such as the Russian SPIN-2
KVR-1000 (2- by 2-m panchromatic; when in orbit) and proposed
sensor systems (EOSAT Space Imaging IKONOS 1- by
1-m panchromatic; Earth Watch Quickbird 0.82 by 0.82 m;
Orbview-3 1 by I m) may provide additional capability.
Large-scale metric aerial photography or digital camera
imagery with spatial resolutions ranging from I 0.25 to 1 m
will still be required to satisfy several important urban/suburban
information requirements.
