Project Initiation: 2009
• Why a Web Platform? • Geokov Overview • Geokov Map Maker • Data Formats • Data Providers • Sharing & Collaboration • Users
Outline
• No platform (operating system & hardware) dependence can access the application from anywhere with an internet connection and web browser
• Access to remote databases as well as real-time data facilitates efficient data and information dissemination, integration, and sharing
• No need for specialized GIS software application, database upgrades and debugging are done from a central location
• A user-friendly interface with only the essential tools / functionality no interaction with complex GIS software
• Facilitates communication and collaboration
Why an online platform?
Geokov Map Maker
Outdoors
Education
A free web application providing:
• user-friendly mapping and visualization functionality • allowing for integration of geospatial data from various sources
Server
Client
Google Maps API Javascript
Microsoft ASP.Net Visual Studio (VB)
Client-Server Architecture
Geokov Map Maker
• Regional, provincial or country-wide web page
• Interactive map • Different base maps; ability to overlay data
• Tools for drawing on the map
• Data import and export
• Direct data read/write to Garmin GPS device
• Distance and bearing calculations
Drawing on the map
Base Maps
Import / Export Data
Gridlines
Distance – Bearing Calculations
Geokov A Data Consumer
Strives to:
• Make data readily available to the end user • Add value to the data
Data Formats
• Web Map Service, KML Nework Link, GeoRss – Suitable for dynamic data – Less maintenance – No access to raw data – Dependent on the provider for availability
• XML (KML, GPX), Shapefile and other GIS file formats – Data conversion needed for GIS file formats – Data currency issue – Data size issue – Control over data presentation / manipulation – Useful for the user with GIS knowledge
Dynamic Data – KML Network Link e.g. Earthquake, Fire, Streamflow, Weather
Web Map Service (WMS) – Changing Data
Web Map Service (WMS) – Static Data
Web Map Service (WMS) – Static Data
KML (Static Data)
Power of Mashup
• GeoBase • GeoConnections • Government of Yukon • Nova Scotia • Alberta Geological Survey • Open Data Canada (Pilot) • Open Data BC
Data Providers
• GeoGratis – Natural Resources Canada Earth Science Sector • GeoBC – Government of British Columbia • GEOweb – District of North Vancouver • Land Information Ontario – Ontario Ministry of Natural Resources • Open data shared by individuals • US National Forest Service • US National Park Service
Data Used from:
Available Data (sampling of North America): • Data.gov • Individual State Data Clearinghouses • Government Ministries / Departments
Many provinces and municipalities have kept their data locked up (collected with tax-payer money)!!!!!
Data storage / sharing, collaborative mapping Import KML to Google maps “My
places”
Expand user base to utilize open data and communicate with maps
