Change Detection
What is Change Detection service?
The changed map resulting from the change detection process shows the spatial distribution of changed features within the area of interest indicated by the customer. The process uses imagery collected before (baseline) and after the changes occur to help identify features from baseline imagery, monitor their condition and identify new features of interest to the customer from subsequent imagery. All changed features and associated statistics are provided in appropriate map formats ready for ingest in the customer’s decision support system.
How is the information used?
Change detection can be used for variety of applications, such as the monitoring of facilities, quantification of re-vegetation activities in disturbed areas, monitoring the movement of oil spills (land and sea), monitoring pipeline encroachment, and monitoring of changes in ice/snow extent. Because imagery used in this process are ortho-rectified, GeoSpatial Partners tailor the feature map such that it fits within the customer’s decision system to support production management, analysis of disturbances due to exploration activities and logistic planning.
Product Value
The energy industry is seeking accurate and timely information about worldwide assets including buildings and disturbed land features resulting from exploration. This spatial data collection, currently based on field surveys, is time consuming and costly. GeoSpatial Partners offer change detection services on user specific features for monitoring and quantifying changes over time, using temporal sequence of imagery. We use high and medium resolutions satellite imagery with their spatial, spectral and temporal characteristics together with proprietary algorithms to produce robust and timely land feature changed maps and associated statistics.
