SHORELINE SURVEY

• Photo Sciences Goals to Completion for the
  CHNEP Shoreline Survey Project.
• Capture an accurate Shoreline for the extent of
  the project area.
• Attribute the Shoreline using Photo
  Interpretation Techniques.
• Conduct QA/QC on the PI and revise.
• Digitally capture the Volunteer Data.
• Connect the Volunteer Data to the parcel base
  inside of the GIS thereby giving the Volunteer
  Data a Spatial Identity.
• Conduct a final QA/QC on the project.
• Deliver product to CHNEP.

CHARLOTTE HARBOR NATIONAL ESTUARY PROGRAM
SHORELINE SURVEY

• Creating a query to select the PI shoreline
  classes within a particular parcel.
• Step 1 Select the parcel you wish to evaluate.
• Step 2 Select from the shoreline data the
  shoreline segments that are within 90. The
  reason we have to use a distance at this point is
  because the shorelines are not necessarily
  reflective of the waterside extent of the
  parcels.
• Step 3 Display the results.

3 Questions posed by Jaime Boswell former
Volunteer Coordinator for CHNEP

• Question Number 1 How many parcels in Charlotte
  County have Trimmed Mangroves?
• Question Number 2 Where are the Mangrove
  Shorelines located that were Damaged?
• Question Number 3 How many miles of shoreline in
  Pine Island Sound have been Hardened?

26
CHARLOTTE HARBOR NATIONAL ESTUARY PROGRAM
SHORELINE SURVEY
Question 1 How many parcels in Charlotte County
have Trimmed Mangroves?

• Solution
• Use the volunteer sheets to answer this question,
  the PI was not tasked to determine whether
  mangroves were trimmed. The PI did determine in
  some instances that the mangroves may be trimmed
  and noted that in the comment field, but this was
  not field verified.
• Select all of the parcels in Charlotte County
  that have a Yes in the Mangroved_Trim field in
  the database.
• Display the amount of records that answer the
  question.
• Of the provided 2,593 Charlotte County Parcels,
  294 or Approximately 11 have Trimmed Mangroves
  as identified by the Volunteers.

SHORELINE SURVEY

• QA/QC Plan
• Scheda Ecological Associates performed an
  Accuracy Assessment where they categorized 500
  randomly selected segments and then compared
  their results with ours. (There are 10,000 PI
  segments for the project area)
• Scheda then captured 50 locations to field check
  to produce a final Photo Interpretation Key these
  locations were also used to validate their
  randomly selected segments and our final draft
  shoreline deliverable.
• PhotoScience then used the 500 segment
  designations to verify our PI interpretations of
  signatures. Out of the 500 segments Scheda would
  have interpreted 8.2 with a slight variation to
  our PI. These slight variations took the form of
  adding another exotic to create a more mixed
  category to changing the damaged designation.
  Scheda disagreed with our interpretation approx.
  5 of the time with most of their changes coming
  in the form of a change from a mangrove to one of
  the exotic types or a mix.
• PhotoScience worked with the Scheda interpreters
  actively discussing the interpretations to
  resolve each of the differing elements. A
  revised shoreline classification was produced at
  the end of the process.
