Image Processing
(Field
Data Collection)
Key Benefits
- Imagery is easily integrated with other spatial data layers
- Features of interest extracted from imagery data
- Digitized aerial photos have an increased shelf life and are available for integrated analysis with other digital/GIS data
Capabilities
I. Scanning/OrthoRectification of Aerial Photos
One of JAYA Corporation's specialties is the conversion of aerial photographs to a digital format. The digital format not only preserves the data in terms of quality and longevity of the photograph, but it also allows for analyses in a GIS/image processing environment. Once the photo is in a digital format, it can be overlaid with other spatial features and geographic data such as roads, boundaries, building, etc. within the same geographic area. This process involves registering the digital photo to a set of specific geographic coordinates, followed by a projection of the photo, if necessary, and then a final projection to the spatial feature/geographic data. If digital feature/geographic data is not available, data layers can be created (digitized) using the aerial photo as the backdrop. Roads can be drawn, boundaries can be delineated, and buildings can be catalogued. As with any GIS layer, the digitized features can be stored with a set of attributes that completely describe that feature (i.e. road type, building name, or land ownership).
Reference Projects
National Park Service, Midwest RegionScanned and orthorectified historical 9" by 9" aerial photographs for various National Park watersheds within the Midwest region. Once scanned and orthorectified, a seamless mosaic was prepared for each area. The mosaic imagery will assist NPS managers in their land-use change and watershed analysis for the areas.
USDA Forest Service, Ozark-St. Francis NF, Southern RegionScanned historical 9" by 9" aerial photographs for Ozark-St. Francis National Forest to be used in change detection and watershed analysis
II. Satellite Image Analysis
Higher resolution imagery data is now readily available. Satellite and aerial imagery with less than 5 meter ground resolution contains a significant amount of data that once processed, translates to information that provides incredible insights into numerous management and engineering issues and areas. JAYA personnel have extensive experience with image processing. Processed imagery identifies and delineates areas requiring attention or extracts/identifies specific features or vegetation. JAYA Corporation uses the ERDAS suite of image processing software to identify and extract such information. Our image analysts are ready to process your requirements from panchromatic to multispectral and hyperspectral imagery.
Reference Projects
NASA Marshall Space Flight Center (MSFC) - Environmental Engineering DepartmentProcessed aerial thermography data to identify and locate water bodies and springs. Once identified and field verified, these springs were used to characterize groundwater within the MSFC site.
Missile and Space Intelligence Center, DIAExtracted specified features from commercial satellite imagery. Support image analyses and the process of extracting features of interest from imagery data acquired from various sensors.
III. Photo Interpretation
Aerial photography and satellite imagery have become powerful tools for mapping the landscape. Air photos have been especially useful in mapping change over time. Digital data layers can be created from these photos mapping aspects like land use/land cover, wetlands, agriculture and urban sprawl.
Reference Projects
National Wetlands Inventory data was updated in part of Escambia County, FL. Air photos (true color and color infrared) were used to create new geographic data layers outlining the current wetlands in the county.
IV. Field Data Collection - Environmental Stewardship
Oftentimes, analyzing particular concerns necessitates the collection of field data coupled with tools offered within the geospatial technologies. Such is the case in processing and analyzing data to support environmental stewardship.
Reference Projects
JAYA
currently performs numerical modeling, environmental impact and risk
assessments, and environmental trace-off analyses for the US Army, Engineer
Research and Development Center. One environmental assessment impact
analysis is monitoring the health of sturgeon population within the Mississippi
tributaries.
Field data is collected on the sturgeon and integrated within a geospatial database to analyze types and occurrence of morphological anomalies in sturgeon population.
