Entiat Region Trails
This map was published in Washington Trails, published by the Washington Trails Association. The map shows trails, trailheads, public lands, and roadless areas. There is a special emphasis on eight hikes that are partially or completely within the roadless areas, and the map also differentiates which hiking trails are also open to motorized vehicles.

Marymoor Park Map
This map was created for King County Parks and the Friends of Marymoor Park. Marymoor is a large regional park located in the City of Redmond on the north end of Lake Sammamish, and is host to numerous recreational and cultural activities--bird watching, rock concerts, bicycle racing, soccer, gardening, and many others. The map will be distributed throughout the park to help park visitors find their destinations and also provide information about the wide variety of resources and facilities. CORE GIS provided cartography, graphic design, and layout.

Geothermal Energy Mapping
This map was created for the Foundation for Geothermal Innovation. The map shows the relationship between geothermal sites identified by the Western Governors Association in their 2006 Geothermal Task Force Report and cities that have enrolled in the Mayor's Climate Protection Agreement. We placed 50 mile buffers around the geothermal sites and identified 60 MCPA cities that fall within this distance. These cities are home to 3.5 million people and contain 1.5 million housing units--all of which could get more of their energy from these geothermal sources.

Columbia River Streaked Horned Lark Habitat Mapping and Analysis
This analysis was conducted for The Nature Conservancy as part of their work to devise a management strategy for several islands in the Columbia River. These islands are used by the U.S. Army Corps of Engineers to dump the drege spoils that result from maintaining the river's shipping channel. This sand deposition creates habitat for the Streaked Horned Lark (Eremophila alpestris strigata), a rare subspecies of the Horned Lark that breeds and winters in Oregon and Washington. CORE GIS worked closely with TNC and WDFW biologists to conduct a detailed analysis of the relationship between the Lark's breeding habitat, sand deposition, and vegetation change. Using imagery from a variety of sources, we created vegetation data for 1996 and 2008 using Berkeley ImageSeg image segmentation software and WEKA data mining software.

Stemilt-Squilchuck Community Vision Conceptual Plan
This map was created for the Trust for Public Land as part of The Stemilt-Squilchuck Community Vision. CORE GIS worked closely with TPL, Chelan County, and a wide variety of farmers, scientists, citizens, and others over the past year and a half to generate a Vision for this remarkable watershed in eastern Washington. The Stemilt-Squilchuck Community Vision honors the wishes of the community by focusing on protecting water resources, conserving critical habitat for fish and wildlife, and maintaining recreational access to public lands. All report materials are available online at www.tpl.org/stemilt.

Wetlands of Mauritius
CORE GIS recently completed a Wetlands of Mauritius map atlas. We worked with The Watershed Company and NWFS Consultancy on an extensive mapping effort for the Government of Mauritius. We converted original AutoCAD files and GPS data gathered in the field to GIS data, and generated an 80 page map atlas of coastal and upland wetlands throughout the island. This map index shows the location of the individual map sheets. The topography for the island was extracted from the Shuttle Radar Topography Mission dataset.

Seattle Park(ing) Day 2008
This map was created for the Trust for Public Land as part of National Parking Day. Park(ing) Day was a "one-day, global event centered in San Francisco where artists, activists, and citizens collaborate to temporarily transform metered parking spots into “PARK(ing)” spaces: temporary public parks." The Trust for Public Land hired CORE GIS to create a map of the park locations in Seattle, to hand out to curious passers-by and help people find the various parks.

Can All Seattleites Get All their Food within 100 Miles of Home?
The non-profit Sustainable Ballard has been active in numerous sustainability and environmental issues, and each autumn they ramp up their "Eat Local" campaign by promoting the 100 mile diet. We decided to take this idea to its logical extreme--what if everyone in Seattle decided to follow the 100 mile diet? Do we have enough agricultural land to support that many people? The result is shown in the map, and there is a more detailed discussion in a CORE GIS blog post here.

San Juan Islands Flight Path
This map was created for the Trust for Public Land as part of a trip they organized for their supporters in summer 2008. Participants travelled by float plane from Lake Union in Seattle to East Sound on Orcas Island in San Juan County. We learned after the trip that when the pilot saw the map, he decided to follow the arrow so his passengers could match the view with the map!

Wenatchee Valley Development Probability
This map was created for the Trust for Public Land as part of the Wenatchee Watershed Vision project. When buying a home or deciding to relocate to a new area, every homeowner has a different checklist of priorities. That said, there are some basic factors, such as water and electricity availability, slope, and proximity to the highway or other roads, that nearly every homeowner considers. This map predicts where such development would likely occur based on these and a number of other variables such as views, distance to rivers and streams, and urban amenities.

John Wayne Pioneer Trail
This map was created for the Trust for Public Land. The map was designed for a TPL-sponsored bike ride along the 22 mile length of this rails-to-trails route in the Cascade Mountains.

Sauk River Estimated Channel Movement Area
This map was created for the Washington Deparmtment of Natural Resources Riparian Open Space Land Owner Program. Working together with LeeSaa Consulting and TerraGIS, we delineated the probable zone of future avulsion events in the Sauk, Nooksack, and Cowlitz rivers and ranked the forested, privately owned parcels to assist DNR in identifying and contacting land owners that might be interested in enrolling in the program.

Measure 37 Claims in the Hood River Valley and Central Willamette Valley
These maps were created for the Sightline Institute. The Hood River and Central Willamette Valleys of Oregon have been ground zero for Measure 37 claims. In the Hood River map, properties with active Measure 37 housing claims are showing in red. Yellow is land that's zoned for agriculture. In the Central Willamette map, each dot represents 10 potential new residents resulting from the Measure 37 claims.

Storm-Related Trail Damage
This map was created for the Washington Trails Association and shows trails and roads that suffered storm damage in the North and Central Cascades and the Olympic Mountains.

Salmon Spawning Survey Maps
These maps were created for the City of Bellevue as a sub-consultant to The Watershed Company. The City of Bellevue conducts an annual salmon spawner survey in the City's salmon spawning streams, and there are often some fairly sizable fish observed, such as this Chinook carcass that was found in Kelsey Creek.

Impervious Surface in the City of Tukwila
This map utilizes impervious surface data from the USGS Seamless site to illustrate the relative level of development along the Duwamish River. Greener areas are less impervious, red areas are more impervious..
