Forecasting climate change impacts to coast redwoods for conservation and communication

Using spatial climate data from weather stations and downscaled climate models, this talk will examine both current trends and future projections for the bioclimate of coast redwood forests. 'Climate space' for coast redwood is defined by the combination of temperature and precipitation values that occur across its range. Shifts in climate space are demonstrated over the last 30 years compared to a 20th century baseline, but the rate, magnitude, and spatial distribution of those shifts varies across coast redwood range, which has implications for contemporary conservation strategies. We translate from GIS to immersive visualization software to animate the future distribution of coast redwood bioclimate as an informal science educational approach for understanding global change impacts to this unique and valued forest ecosystem.

Caltrans District 4's (SF Bay Area) Google Earth mapping systems

Caltrans has successfully georeferenced over 6000 Caltrans right of way maps and are now serving them out to our staff in the region. Additionally, the georeferenced images provided us with the basis for the creation of a vector right of way layer for the District. This layer has in turn been the basis for the creation of several additional data layers which are now shared with local governments and agencies.

Everything --- All At Once! Community 1:1000 Base Mapping

Case study of one organization's quest for the nexus of mobile base mapping, topo-bathy terrain building, hydrography and wetland mapping. Everything, all at once at 1:1000 scale. Iterative development of topo-bathy integrated terrain (for 3 years), local-resolution updates for National Hydrography Dataset (2-1/2 years), ESRI Community Map implementation (2 years), and local-resolution updates for National Wetland Inventory (1 year) have been found to have significant overlap, and thus synergy for data development efforts. High-quality cartography at 1:1000 scale and larger has been recognized to offer substantial support for mobile devices involved with field data capture.

The Demise of NGS Control - What Does it Mean For Your GIS?

The NGS is no longer maintaining "passive" survey control monuments. What does this major change in their role mean for your GIS? This presentation will answer this question and these other related questions:

1) How is survey control related to the production of geospatial data?

2) Why are passive survey control monuments important?

3) What will NGS be doing to provide survey control as we move into the future?

4) What holes in the maintenance of survey control will need to be filled by local government, non-profits, and private companies?

The presentation will conclude with a summary of volunteer work performed by the CLSA Central Valley Chapter to establish the California Central Valley Control Network.

Location Anonymization

It is possible to anonymize the track of someone's movements by blurring their positions when they leave the public space. Detailed maps are used to identify public places (e.g. major roads, parks, shopping malls).

The anonymized tracks are useful for retail site selection, transportation planning, etc.

The method was issued a patent in May. And I presented it at LocationIntelligence and UbiComp.

Details and a demo are at LocationAnonymization.com.

I am the inventor. My real background is in social science and research methods. So, I know a lot more about what makes good data than about mapping. And I'd welcome the chance to present to maps experts and see if I can answer their questions.
