From Satellite Imagery to Spatial Intelligence
How earth-observation imagery can move through preparation, segmentation, classification, feature extraction, and GIS integration.
Imagery is a starting point
Satellite imagery can provide broad-area observations across cities, land, coastlines, vegetation, and environmental contexts. The image itself is not the final intelligence product; preparation and interpretation are required before features can be used in a spatial workflow.
Segmentation and classification should be selected for the geographic features, time period, source imagery, and intended decisions rather than presented as a generic visual effect.
Extracted features need a GIS home
Roads, buildings, water, vegetation, land cover, and change areas become more useful when the extraction process is documented and the results are delivered into a shared GIS context. Review and validation remain part of the information chain.
Apply this to a project
The appropriate method depends on the environment, decision, control strategy, deliverables, and quality plan.
