Oregon Imagery Explorer: accessing .5 m Color Imagery

“I'm delighted that recent aerial photo imagery is so easily available for the state, and in such a high resolution - thank you! The Oregon Imagery Explorer has made my project, and I'm sure that of many others, much easier.” - Student in the Botany and Plant Pathology Department, 1/26/2010

GIS Mapping Tools – “all natural issues are tied to place” 2002 needs assessment user response

Example of Oregon Explorer Output Map

Carolyn Bales of Corvallis is a backpacker and bird watcher. She says she’s used the Willamette Basin Explorer a dozen times to plan outings and to locate access points to water where birds abound. “Oregon Explorer saves me from having to buy maps, and acquaints me with areas I might not have discovered otherwise,” she says.

How can Oregon Explorer increase understanding of natural resource issues?

Land Use Change – Measure 37 and 49 Viewers

As a former member of the Corvallis Planning Commission and a courtesy faculty member in the geosciences department at OSU, Denis White has an interest in land use planning issues. He says that when he went to the Land Use Explorer site to check on Measure 37 claims near his home, he made some startling discoveries. “To my knowledge, the Measure 37 viewer on the site is the only place on the Web to get detailed maps and information about individual claims,” he says. “It’s a very useful resource.”

• Faye Stewart, a Lane County commissioner, says he’s impressed by the quality and quantity of demographic information he’s able to access on the Rural Communities Explorer. He’s able to glean valuable socioeconomic data for his district, as well as maps and geographic information. He says he especially appreciates the feature that allows him to hone in on areas of his district using aerial photos and apply overlays of land use designations and natural resources such as wetlands. “This is a powerful tool that will help me track trends in my district,” he says. “It also will be useful as we apply for block grants for facility upgrades.”

Marc Rempel onOregon Explorer Mashups

What is a mashup?

• a mashup is a web page or application that combines data or functionality from two or more external sources to create a new service.

• The term mashup implies easy, fast integration, frequently using open APIs and data sources to produce results that were not the original reason for producing the raw source data.

» Source: Wikipedia.

Mapping API(google maps, bing maps, etc)

Spatial Data Web application

Oregon Explorer MashupsWhy Oregon Explorer uses mashups:1.Focuses around a particular topic theme.2.Engaging, interactive interface.3.More flexibility in how to present maps and content.

Measure 37 Viewerhttp://oeapp.oregonexplorer.info/M37Viewer

• Explores Measure 37 claims with the ability to overlay informational layers.• Virtual Earth/Bing Maps- JavaScript API• Overlay Web Map Service (WMS) from ArcIMS

– Transparency slider, legend• Create active objects (pushpins, polygons).

– Uses GET_FEATURES call to ArcIMS to draw polygons.• 3D Functionality.

ORWAP- Oregon Rapid Wetland Assessment Protocol http://oregonexplorer.info/wetlands/ORWAP/

• Creates a habitat sensitivity score for a selected point.• Uses ArcGIS server map and geometry services.• Buffers selected point and queries intersection of layers.• Uses Bing Maps JavaScript Extension for ArcGIS server.

Oregon Watershed Restoration Tool http://oregonexplorer.info/OregonRestorationVisTool/

1. Displays restoration project information by basin and watershed councils.2. ArcGIS Server 9.3.1 mapping backend3. REST and SOAP used for getting layer data and overlaying WMS.4. DOJO JavaScript class library for more interactive user interface.

Components of Web GIS(to be continued in GEO 580)

1. Spatial Data– Shapefiles/ Geodatabases (ESRI)– KML/KMZ (Google Earth)– GeoRSS/GeoJson

2. Mapping Server– ArcIMS / ArcGIS Server – GeoServer– MapServer

3. Web servers– Apache Tomcat– IIS (windows)

4. Mapping Application– ESRI WebADF/JS APIs– Google Maps API /ArcGIS Extension– Google Earth API– Bing Maps API /ArcGIS Extension– Bing Maps Silverlight API (Microsoft)– Flex (Adobe) / ArcGIS Extension– Yahoo Maps API– OpenLayers API– ArcGIS for iPhone API coming soon.

5. Mapping Enhancements

– JavaScript Class Libraries– Dojo, EXT.JS, YUI, jQuery

A simple web mapping application

• Basic HTML and JavaScript will get you a long ways.
