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

4

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

11

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
