Data Availability
• Making field survey data available to the many different stakeholders in biodiversity is one of the aims of the PPBio Program
wildlife managers, foresters, local councils,
local communities, fisheries biologists
pharmaceutical laboratories, scientists
conservationists, politicians
catchment management authorities

Biological Inventory Database - BID
Designed to allow the storage and future
retrieval of field data obtained in PPBio
standardized surveys throughout Amazonia

BID Repository Characteristics
• Generic - Accommodates data of any kind of inventory, even future ones for which the survey design still has to be established
• Spatially enabled - inventory observations of whatever kind are geographically referenced, at documented spatial precision levels
• Accommodates the support of end-users, such as scientists that conduct inventories, as well as future users of the data
![Page 5: A Generic Spatial Repository for Biodiversity Inventory Data Debora P. Drucker, UNICAMP, Brasil Rolf A. de By, ITC, The Netherlands José Laurindo C. dos.](https://reader035.fdocuments.in/reader035/viewer/2022081520/5697c0091a28abf838cc6f1e/html5/thumbnails/5.jpg)
A Generic Repository
• It is a priori unknown what kind of data will be
accumulated
• Statically defined tables do not satisfy the data
management needs of this application
• The data model for our application only
identifies truly generic notions such as Survey,
Survey Variable, Observation, Observer, Plot,
Researcher

Surveys
• A survey comprises methodical fieldwork in a area, usually at multiple locations in the area, over a known period of time
• Standardized observations are made at each of the locations
• Locations can be positions along an indicated trail, along the course of a creek or river, or fixed points on a grid system
![Page 7: A Generic Spatial Repository for Biodiversity Inventory Data Debora P. Drucker, UNICAMP, Brasil Rolf A. de By, ITC, The Netherlands José Laurindo C. dos.](https://reader035.fdocuments.in/reader035/viewer/2022081520/5697c0091a28abf838cc6f1e/html5/thumbnails/7.jpg)
Collecting and non-collecting surveys
• Collect material for a single survey location
• May generate additional observations in situ: time, humidity, substrate
• Generates a number of observations for each survey location
• Visual encounter surveys or auditory sampling
![Page 8: A Generic Spatial Repository for Biodiversity Inventory Data Debora P. Drucker, UNICAMP, Brasil Rolf A. de By, ITC, The Netherlands José Laurindo C. dos.](https://reader035.fdocuments.in/reader035/viewer/2022081520/5697c0091a28abf838cc6f1e/html5/thumbnails/8.jpg)
Locational and transect surveys• Some surveys, by
their design, list the exact locations at which observations will have to be made
• Tree surveys at defined plots
• Other surveys identify a transect along which observations are made
• Each observation registered individually with further positioning information (distance along the trail, distance from the trail)
![Page 9: A Generic Spatial Repository for Biodiversity Inventory Data Debora P. Drucker, UNICAMP, Brasil Rolf A. de By, ITC, The Netherlands José Laurindo C. dos.](https://reader035.fdocuments.in/reader035/viewer/2022081520/5697c0091a28abf838cc6f1e/html5/thumbnails/9.jpg)
• People– Researcher: survey
responsible– Personalized
survey:observer, responsible for each one of the observations or collecting events
• Subsurvey:– Additional
observations that cannot be directly connected with the main observations
– In avian studies, start time and end time of a transect visit important

Survey localities• Reserve: study site,
a polygon a set of polygon features
• Trail: laid out path, a linestring
• Igarape: creek, a linestring
• Terrestrial, aquatic and riparian plots: points
• Along-trail-based locality and off-trail-based locality: points

Support of End-Users
• modular set-up that accommodates easily the support of end-users, such as scientists that conduct inventories, as well as future users of the data
• allows extensions of the system in the future with functions currently unknown

Challenges• Integration with Biological Collections Information
Systems
• Complete the function services, under strict genericity, consistency and robustness requirements.
• Demonstrate the system’s viability in practice
• Develop functional support for spatio-analytic work.
• Showcase the phenomenal potential for cross-correlation between surveys, and develop an application for end-users to do such scientific enquiries
