      Veteran GISMO Members introduced themselves to the group.

      GISMO Program: OASIS (Notes by Charlie Ridgway)
      Steve Romalewski (NYPIRG-CMAP), Johan Herrlin (ESRI NYC) and Lenny
      Librizzi (Council on the Environment of NYC) presented. They were
      colleagues in developing the OASIS Tree Mapping Project, one of
      many useful coverages available in OASIS.

      *There are an estimated 500,000 street trees in New York City

      The tree project was a demonstration project funded by the US Forest
      Service to demonstrate the feasibility of assembling open space
      resources to apply them to a common theme. In this case that theme
      was street trees. The project covered small plots in three
      neighborhoods in a swath across New York City. The neighborhoods
      were chosen to represent three broad habitats:

      * Hunts Point, The Bronx: few trees but a high potential for tree
      * Lower East Side, Manhattan: moderate planting and moderate
      potential for future planting
      * New Brighton, Staten Island: suburban community with heavy tree

      * 322 trees were surveyed for the project. They have an estimated
      replacement value of more than $1M.

      Data collection, presented by Lenny Librizzi, Council on the
      Environment of NYC, was handled by certified tree pruners. These are
      people who have been trained to care for city trees and are familiar
      with the various species and what they look like in health and
      sickness. Various parameters about each tree in the study area were
      collected such as species, diameter at breast height, height,
      percent crown cover, state of health, tree pit information. The
      teams in The Bronx and Manhattan collected the information on paper
      forms while the Staten Island team used handheld computers equipped
      with ArcPad.

      The ArcPad application was developed by Johan Herrlin of ESRI who
      described it. The application uses limited data (street and building
      footprint layers from the NYC basemap) because of the memory
      constraints of the palmtops. Trees were placed on the map manually
      rather than using the GPS capabilities of ArcPad because the actual
      location was more accurate given the inherent error of consumer
      grade GPS and the effects of multipath. Once a tree was located the
      application prompted the team to enter all the necessary data about
      that tree. The application asked pertinent questions based on
      previous replies and validated those replies on the spot. This has
      the obvious advantage of assuring that complete and accurate
      information is collected about each tree the first time. Data
      collected on the paper forms was transferred to a copy of the ArcPad
      application located in the office and Lenny reported that the hand-
      written data was basically as accurate as that collected using
      ArcPad in the field.

      The collected data was forwarded to the US Forest Service where it
      was processed with an algorithm that calculated the replacement
      value of the tree, the amount of pollution removed from the air by
      the tree, amount of pollution contributed by the tree, and the value
      of the tree relative to its ecological function.

      Finally the data was transferred to CMAP where it was plotted and is
      made available to the public on their Open Accessible Space
      Information System for New York City (OASIS) Steve Romalewski
      (NYPIRG-CMAP) provided an overview of the CMAP application. He
      advised users that the data available for inclusion on OASIS is a
      mix and match of data layers of differing vintages and qualities.
      Not all coverages conform to the NYC basemap. Scales of the various
      coverages do not always match so some coverages may sometimes drop
      out of the map. There isn't a lot of metadata available about the
      coverages right now but CMAP is working to improve both quantity and
      quality. They are also planning to make unrestricted coverages
      downloadable as shapefiles.
