INTRODUCTION
PEI to create and implement an archaeological predictive model for the review and permit process Based off of New Brunswick’s current localized predictive
model Will predict the archaeological sensitivity or potential of
unsurveyed areas
Query-based User is able to query attributes the database of registered
archaeology sites
Potential for an abundance of undiscovered sites Everything over 100 years old is considered an
archaeological artifact PEI has been inhabited for thousands of years

CONCEPT OF MODEL
Will use base layers from Federal and Provincial governments Increasingly more LiDAR data is used Other layers created through digitizing historic maps
Historic building footprints overlain with current footprint
Areas that do not overlap are flagged
Consultants ground truth the area If walkover matches model, it is business as usual If not, reviews may be made to the model

POTENTIAL MODELLING OUTPUT

DATA PREPARATION
Phase 1: Translate files from MapInfo to ArcGIS format
Create feature datasets and feature classes
Georeference historical maps of Prince Edward Island 150+ images from 7 different maps Dates range from 1765 to late 1800s Georeferenced to the National Road Network (or
coastline, where applicable)

COMPLICATIONS
Some maps did not contain roads Survey techniques of the period
Good Bad

BENEFITS OF THE MODEL
Developers will now be able to avoid areas of potential (archaeologically sensitive)
Used by government departments as an early determinant for impact on an Aboriginal Right
A tool for estimating the potential costs of developing an area
Gives all archaeologists the same initial scope for bidding on sites For budgeting purposes
It can be refined and improved over time through feedback
Outputs can be sold to developers, generating revenue for overhead costs
10
LIMITATIONS OF THE MODEL
Expensive Startup costs are greater than $12,000
Is meant as a planning aid Can not replace a professional impact assessment
Susceptible to false negatives, impacting the overall functionality Crucial to use same testing methodology

CONCLUSIONS
To be determined
PART 2: MAP TOUR OF NSCC INTERNATIONAL PROJECTS USING ArcGIS ONLINE
13
INTRODUCTION
NSCC International is involved in may projects: International Learning Programs International and Immigrant Student Experiences Capacity Building Projects (Leave for Change)
Looking for a new way to present their projects to the public Map Tours are a neat new way of presenting data that is
both effective and user-friendly
Requires only a free public account to create!
14
DATA PREPARATION
CSV method with 7 data fields Name, description, icon colour, longitude, latitude, picture URL,
and thumbnail URL Can optionally add a video in place of a picture
Order of information in CSV determines the order of pins
Currently, NSCC International uses a blog system to display their stories Retrieved and adapted information from here to put on the tour
Coordinates are in decimal degrees, and were obtained from Google Earth
15
DATA PREPARATION
Use HTML to enhance layout of information on slides Horizontal references, italics, webpage links, changing font
size and colour
