● Purpose● Why we chose this project● Obtaining the data● Network Analysis● Creating a Web Map● Using a JavaScript API● Demonstration of the web application

Presentation Topics

Purpose & Objectives● Improve future students’ access to rent information and useful

information about Annapolis Valley through a web application○ Determine factors that influence decision-making process of

renting a place○ Use Network Analysis to identify commute times from rental

locations to COGS○ Create a GIS-based web application with the use of ArcGIS

Online API for JavaScript and ArcGIS Online’s web map

Why We Chose This Project● After deciding to attend COGS

○ We were unaware of all the rental houses available ○ Did not know where/ how far away stores were○ Did not know about activities/ sightseeing in

Annapolis Valley○ Wanted to complete a project that would benefit

future students

What Future Students Need to Know● Possible rental locations

○ Price, # of rooms, Distance, ect. ● Grocery stores/ shopping stores● Restaurants/ bars● Points of interest ● Banks● NSLC● Hairdressers

Data Provided● Road network ● County data

○ Modified into a study area polygon

● Both provided from Konrad’s Network Analysis course

Data Collected● Rental Information ● Businesses & POIs● Trails (GPS data

collection)

Rental Information ● Survey from students

Rental Information● Contacted landlords on Kijiji &

Places4Students● Asked from them for the same information

that was on the survey

Points of Interests & Business Information● Google Maps, Yellow Pages, Tourist Sites, & Company

sites were utilized

Points of Interests & Business Information● Ran into errors with Google Maps data

○ i.e. Pearles

Points of Interests & Business Information● To verify the location of all the points, Google’s street view was used

Organizing the Data into CSVs● Each type of data was organized into its own spreadsheet

on Google Drive and then downloaded as a CSV

Trail data● Could not locate features with

satellite imagery● The Hippie houses, Saint Croix

Cove Falls, Roxbury, and the trails to get to these locations were not provided

● Used a Juno GPS to collect point and line features

Trail Data - Planning● Prior to collecting the data used GNSS

Planning website ○ More satellites are better and can improve accuracy ○ DOPs is a measure of the quality of GPS positions,

based on the geometry of the satellites (GPS Pathfinder Software Help, 2009)■ Lower DOP is better

Differential Correction● From COGS

Base Station

GPS Data● Line features

for the trail were not as precise as originally hoped

● Had to alter the vertices to straighten the trail

Transformations● Our data was unprojected● Juno collects data in WGS84● Used the Transformation and projection tool

in ArcMap to transform the data into WGS 1984 Web Mercator (Auxiliary Sphere)

Meaningful Symbology● Found company logos, edited them in both

Paint & Corel Paint X6, then uploaded them into ArcMap

● Scale dependent symbology

Network Analysis● Determine the walking & driving distance from each

rental unit to COGS● Completed by:

○ Making assumptions of road types & speed limits ○ Using Google Earth to find exact speed limits for HWY 1○ Add walking trails○ Create a network dataset ○ Complete analysis○ Update shapefile

Network Analysis● Making assumptions of speed limits & walking speed

○ A particular road type has a corresponding average speed limit○ According to an article in the Journal of Neurophysiology, the average

walking speed is about 5km/h

Network Analysis● Found exact speeds for highway 1 through Google Earth’s street view

○ It is the most heavily used road by students commuting to school and to the surrounding amenities

Network Analysis

● Add walking trails to the road network○ Through the

parking lot behind COGS

○ Along the train track trail

Network Analysis● Created a network

dataset○ Set parameters

■ Connectivity policy

■ Fields needed for directions

■ Imperial to metric

Network Analysis● Determining the

Distance and Time from each rental house to COGS○ Created a New

Closest Facility■ Set COGS as the

Facility■ Set the Rental

Houses as the Incident

Network Analysis● Completed the

Network Analysis ○ Produced

directions for each house

○ Took the total time and distance and created a CSV

Network Analysis● Joined the CSV to the

shapefile ● Completed twice, once

for driving and second for walking

Create a Web Map● Shared as Service● Connected to the

COGS server● Chose the Feature

Access Capability

Creating a Web Map ● Tiled Mapping VS Feature Access

Creating a Web Map● Added a Summary,

Tags, & a Description ● Clicked Analyze and

resolved all errors

Setting Parameters in ArcGIS Online● Created it so the icons would appear at

certain extents ○ Uploaded each layer twice, one for the zoomed in

symbology and another for the zoomed out symbology

● Changed the settings so only the rental houses can be edited by the public

DEMO!!

Setting Parameters in ArcGIS Online● Allowed for each attribute in most layers to

be searchable

Using JavaScript API for Customization● Need a webserver to host the API

(Application Programming Interface)○ Could not find a free webserver

■ Google Drive allows for HTML and CSS files to run, but not JavaScript files

■ Drop Box no longer makes public folders for free accounts

■ Had to use a friends webserver from school, but could be kicked off at anytime

Issues with JavaScript API● Searchable layers not appearing● Directions widget missing

○ ESRI disabled the directions widget for the public○ Found directions on Google Maps from COGS to

Each point and added the link to the attribute table

DEMO!!

Conclusions● Identified and investigated variables that were important

in the decision-making process of renting a place● Determined commute times from possible rental

locations to COGS with Network Analysis● Developed a web application that

○ presents an effective method to communicate rental information and important amenities

○ uses ArcGIS Online API for JavaScript and ArcGIS Online’s web map

Acknowledgements● Dave MacLean, as our project supervisor, as well as for

his help while working on this project ● Kathleen Stewart for her patience, help and knowledge

of JavaScript● Darren MacKinnon for his help and assistance with

using the Juno and getting the base station data
