MOTIVATION
UNCONVENTIONAL METADATA
METADATA ENCODING
CAM2 currently has access to more than 100k cameras producing a substantial amount of data that needs to be managed and processed for further use.
Cameras Worldwide Cameras in the US
Our goal is to construct a suitable infrastructure and systematic procedures for data curation and distribution to handle massive amount of data.
Apart from the conventional image metadata like time of creation, dimensions, camera model, etc., we are adding other metadata such as :
geographical coordinates,
projections (i.e. objects in the image),
direction of camera,
landscape, etc.
Incorporating Dublin Core standard metadata element set to design a metadata schema encoded using XML for existing metadata.
Sample encode information with Dublin Core.
INFRASTRUCTURE
Sequoia and Kings Canyon National Park
Grand Canyon National Park
Analyzing various policies involving copyrights, data sharing, user restrictions, technical instructions, etc. to ensure proper compliance of agreements proposed by our data providers.
Examining the Big Data life cycle in order to construct our own adaption of data curation infrastructure.
Annotated CAM2 images in compliance with existing metadata standards adds tremendous value and is crucial for use in conducting further processing and research.
FUTURE WORK
Indiana Department of Transportation Data Policy
Produce a project wide metadata schema for use in all of CAM2 data to facilitate data management and distribution.
Setting up the centralized infrastructure to host our data inventory and metadata database.
Initiate a semi-automated process for data storage and metadata generation
Propose a uniform data policy across all our data providers

Applying various image processing techniques, we could calculate the number of humans, the count of cars, the coordinates of bounding boxes, and incorporate these results in the metadata.
