Outline

• Brief descriptions
• High Resolution orthoimagery (HRO)
• GIS dataset
• Complexities using PREMIS for these Geospatial
  Resources
• Further investigations

3
High Resolution Orthoimagery (HRO) Monterey Bay
Aquariam

• Description
• Collection of various files comprising a classic
  shapefile
• Additional files created by SW for rendering

• Curatorial Decisions
• What is to be archived?
• For what purpose?
• What is context for the artifact?
• How much of context should be archived?

4
Compiled GIS Dataset Network of San Francisco
Bay Area snapshot

• Description
• Compilation of data layers
• Only certain data points featured from layers
• Output
• Image as tourist map
• MS Access personal geodatabase

• Curatorial Decisions
• What is to be archived?
• For what purpose?
• What is context for the artifact?
• How much of context should be archived?

5
Application of PREMIS to HRO GIS Dataset
complexities

• Structural Aspects
• Contextual Aspects
• Function / purpose of data subset created
• Provenance whats important to record
• Events to be recorded

6
Application of PREMIS to GIS Dataset Structure
of artifact

• Dependent upon
• archival unit
• ?map output
• ?compiled dataset output as .mdb
• ?each layer component
• ?all of the above
• how determine relationships got MD?

• Use of ltobjectgtrelationship
• Or,
• Use of METS
• Both

7
Application of PREMIS to GIS Dataset Context
Provenance with artifact

• Intention To make earth science data useful to
  the scientific community, longterm

• Earth science data community emphasizing the
  importance of context provenance

8
Guidance from NASA NOAA from US Global
Change Climate Report

• As necessary the processing software, instrument
  operations history and related science
  documentation
• Information intended to support understanding and
  use of the data in the long term (i.e., after
  instrument operations end)
• Standard linkages among the critical data and
  instrument information, including provenance
  information
• NOTE Lineage or provenance data considered as
  the processing steps used to create scientific
  data product

9
Guidance from NASA NOAA more specifically,
e.g.,

• Instrument/ sensor characteristics such as
• performance measurements
• calibration data method
• Processing algorithms their scientific basis
  for creation of the product, for example
• Bibliography of pertinent Technical Notes and
  articles reporting on research using the data set
• Feedback from users of the dataset
• etc.,

10
Context Provenance in PREMIS where?

• ltobjectgt
• significantProperties using extension element?
• objectCharacteritics using extension element

• Use elements from domain specific MD standards,
  e.g,
• FGDC see ref in Sources
• North American Profile of ISO 191152003
  Geographic Information, Metadata
• Data Documentation Initiative (DDI)

11
PREMIS Complex Geospatial Data

• For more detail on using domain specific
  metadata, see An Investigation into Archiving
  Geospatial data Formats prepared for NGDA
  Project, funded by NDIIPP (http//www.ngda.org/res
  earch.php)
• Approaches of FGDC, PREMIS, and Center for
  International Earth Science Information Network
  (CIESIN)s Geospatial Electronic Record (GER)
  model on basis of
• Environment/ computer platform
• Semantic underpinnings
• domain specific terminology
• provenance
• data quality
• appropriate use

12
Context Provenance in PREMIS where?

• What influenced or impacted the creation of the
  dataset to understand the data
• Addition of metadata to the resource, e.g., USGS
  which added FGDC MD to HRO from Monterey Bay
  Water Resource

• lteventgt

Example Event to be documented Merge
c\temp\states1c\temp \states2 c\temp\USA
13
Context Provenance in PREMIS where?

• ?Agency adding descriptive MD to HRO, e.g., USGS
  addition of descriptive info from the Monterey
  Water District

• ltagentgt

14
Implementation issues

• Heavy emphasis upon receiving documentation,
  metadata, and reference materials at time of
  creation and/or acquisition from
• governmental agency sponsoring
• research scientists creating
• In order to do this practicably, need to be able
  to determine factors for creation / archiving the
  artifact. -- include link to taxonomy in the
  PREMIS schema in lieu of TYPE semantic unit
• How?
• Chance of being built into tools eventually,
  e.g., GeoMedia, ESRI ArcGIS tools
• In process of building domain concensus of
  importance of archiving

15
Further investigations

• ESIP Federation building a MD testbed for
  preservation MD (NOAA NASA, etc.,)
• American Geophysical Union position statement
  follow-up
• NDIIPP geospatial projects including NGDA and
  collaborative states
• Discussions of significant properties /
  characteristics Dappert, Farquhar article
