California parcel data download

Parcel data for California summary and download here. http://egis3.lacounty.gov/dataportal/2015/09/11/california-statewide-parcel-boundaries/

The data are not complete. But downloadable in geodatabase format. 

"A geodatabase with parcel boundaries for 51 (out of 58) counties in the State of California. The original target was to collect data for the close of the 2013 fiscal year. As the collection progressed, it became clear that holding to that time standard was not practical. Out of expediency, the date requirement was relaxed, and the currently available dataset was collected for a majority of the counties. Most of these were distributed with minimal metadata."

SNAMP project wrap-up: relationships made and lessons learned

The Sierra Nevada Adaptive Management Project SNAMP

Word cloud from our 31 recommendationsThe Sierra Nevada Adaptive Management Project is a joint effort by the University of California, state and federal agencies, and the public to study management of forest lands in the Sierra Nevada. This 10-year project to investigate the effects of vegetation management treatments implemented by the Forest Service on fire risk, wildlife, forest health, and water in two areas in the Sierra Nevada, in the Sierra National Forest and the Tahoe National Forest. A lasting solution to forest management must engage stakeholders and promote active public participation in all phases of the process, including the development, interpretation, and incorporation of research-based information in the adaptive management decision making process.

My group was involved in both the spatial analysis work and public participation efforts. It has been a great honor to work on this project, as well as being a tremendous learning experience. Two wonderful dissertations from my lab have resulted from this research: Marek Jakubowski and Shufei Lei. So many students and staff worked on the project during its 10 year run: Qinghua Guo was instrumental to the project from UC Merced; Ken-ichi Ueda began work on the website in the early years of the project; Shasta Ferranto added years of insightful work on the public participation team; everyone in the lab participated in some way to the outcomes; and we all learned so much and made tremendous networks of expertise and knowledge across the state.

Our summary from SNAMP: 31 integrated recommendations

The following forest management recommendations consider the SNAMP focal resources (forest, water, wildlife), as well as public participation, as an integrated group. These recommendations were developed by the UC Science Team working together. Although each recommendation was written by one or two authors, the entire team has provided input and critique for the recommendations. The entire UC Science Team endorses all of these integrated management recommendations. Click at the bottom of the post for the full description of each recommendation. 

Section 1: Integrated management recommendations based directly on SNAMP science

Wildfire hazard reduction

1. If your goal is to reduce severity of wildfire effects, SPLATs are an effective means to reduce the severity of wildfires. 

SPLAT impacts on forest ecosystem health 

2. If your goal is to improve forest ecosystem health, SPLATs have a positive effect on tree growth efficiency.

SPLAT impact assessment

3. If your goal is to integrate across firesheds, an accurate vegetation map is essential, and a fusion of optical, lidar and ground data is necessary. 

4. If your goal is to understand the effects of SPLATs, lidar is essential to accurately monitor the intensity and location of SPLAT treatments.

SPLAT impacts on California spotted owl and Pacific fisher

5. If your goal is to maintain existing owl and fisher territories, SPLATs should continue to be placed outside of owl Protected Activity Centers (PACs) and away from fisher den sites, in locations that reduce the risk of high-severity fire occurring within or spreading to those areas.

6. If your goal is to maintain landscape connectivity between spotted owl territories, SPLATs should be implemented in forests with lower canopy cover whenever possible.

7. If your goal is to increase owl nest and fisher den sites, retain oaks and large conifers within SPLAT treatments.

8. If your goal is to maintain fisher habitat quality, retention of canopy cover is a critical consideration.

9. If your goal is to increase fisher foraging activity, limit mastication and implement more post-mastication piling and/or burning to promote a faster recovery of the forest floor condition. 

10. If your goal is to understand SPLAT effects on owl and fisher, it is necessary to consider a larger spatial scale than firesheds.

SPLAT impacts on water quantity and quality

11. If your goal is to detect increases in water yield from forest management, fuel treatments may need to be more intensive than the SPLATs that were implemented in SNAMP.

12. If your goal is to maintain water quality, SPLATs as implemented in SNAMP have no detectable effect on turbidity.

Stakeholder participation in SPLAT implementation and assessment

13. If your goal is to increase acceptance of fuel treatments, employ outreach techniques that include transparency, shared learning, and inclusiveness that lead to relationship building and the ability to work together.

14. If your goal is the increased acceptance of fuel treatments, the public needs to understand the tradeoffs between the impacts of treatments and wildfire.

Successful collaborative adaptive management processes

15. If your goal is to establish a third party adaptive management project with an outside science provider, the project also needs to include an outreach component.

16. If your goal is to develop an engaged and informed public, you need to have a diverse portfolio of outreach methods that includes face to face meetings, surveys, field trips, and web-based information.

17. If your goal is to understand or improve outreach effectiveness, track production, flow, and use of information.

18. If your goal is to engage in collaborative adaptive management at a meaningful management scale, secure reliable long term sources of funding.

19. If your goal is to maintain a successful long-term collaborative adaptive management process, establish long-term relationships with key people in relevant stakeholder groups and funding agencies.

Section 2: Looking forward - Integrated management recommendations based on expert opinion of the UC Science Team

Implementation of SPLATs

20. If your goal is to maximize the value of SPLATs, complete treatment implementation, especially the reduction of surface fuels.

21. If your goal is to efficiently reduce fire behavior and effects, SPLATs need to be strategically placed on the landscape.

22. If your goal is to improve SPLAT effectiveness, increase heterogeneity within treatment type and across the SPLAT network.

Forest ecosystem restoration

23. If your goal is to restore Sierra Nevada forest ecosystems and improve forest resilience to fire, SPLATs can be used as initial entry, but fire needs to be reintroduced into the system or allowed to occur as a natural process (e.g., managed fire).

24. If your goal is to manage the forest for long-term sustainability, you need to consider the pervasive impacts of climate change on wildfire, forest ecosystem health, and water yield.

Management impacts on California spotted owl and Pacific fisher 

25. If your goal is to enhance landscape habitat condition for owl and fisher, hazard tree removal of large trees should be carefully justified before removing.

26. If your goal is to minimize the effects of SPLATs on fisher, SPLAT treatments should be dispersed through space and time.

Management impacts on water quantity and quality

27. If your goal is to optimize water management, consider the range of potential fluctuations in precipitation and temperature.

Successful collaborative adaptive management processes

28. If your goal is to implement collaborative adaptive management, commit enough time, energy, and training of key staff to complete the adaptive management cycle.

29. The role of a third party science provider for an adaptive management program can be realized in a variety of ways.

30. If the goal is to implement adaptive management, managers must adopt clear definitions and guidelines for how new information will be generated, shared, and used to revise subsequent management as needed.

31. If your goal is to increase forest health in the Sierra Nevada, we now know enough to operationalize some of the aspects of SNAMP more broadly.

SNAMP spatial recommendations: Lidar + accurate veg maps needed for forest management

The SNAMP UC Science Team worked together to develop 31 integrated management recommendations at the conclusion of our SNAMP project. The following deal specifically with lidar and vegetation mapping. All 31 can be found here. All our SNAMP spatial publications can be found here

Mapping forests for management

Lidar point cloud forest stand: Marek Jakubowski

If your goal is to integrate across firesheds, an accurate vegetation map is essential, and a fusion of optical, lidar and ground data is necessary.

Lidar data can produce a range of mapped products that in many cases more accurately map forest height, structure, and species than optical imagery alone. Our work indicated that the combination of high-resolution multi-spectral aerial/satellite imagery with lidar is very helpful in mapping vegetation communities as well as characterizing forest structure zones.

If your goal is to understand the effects of SPLATs, lidar is essential to accurately monitor the intensity and location of SPLAT treatments.

Lidar data can effectively penetrate the forest canopy and can be used to accurately detect forest understory changes. Our work indicated that the use of lidar-derived vegetation structure products (e.g., canopy cover and vegetation height) significantly outperformed the aerial image in identifying the SPLAT treatment extent and intensity.

SNAMP wrap up: Forest Service should implement proposed forest treatments

SNAMP field trip: photo from Shufei LeiFull press release: http://ucanr.edu/?blogpost=19857&blogasset=81020

After conducting extensive forest research and taking into consideration all aspects of forest health – including fire and wildlife behavior, water quality and quantity – a group of distinguished scientists have concluded that enough is now known about proposed U.S. Forest Service landscape management treatments for them to be implemented in Sierra Nevada forests. We say:

“There is currently a great need for forest restoration and fire hazard reduction treatments to be implemented at large spatial scales in the Sierra Nevada.”

“The next one to three decades are a critical period: after this time it may be very difficult to influence the character of Sierra Nevada forests, especially old forest characteristics.”

The scientists' recommendation is in the final report of a unique, 10-year experiment in collaboration: the Sierra Nevada Adaptive Management Project (SNAMP). A 1,000-page final report on the project was submitted to the U.S. Forest Service at the end of 2015. In it, scientists reached 31 points of consensus about managing California forests to reduce wildfire hazards and protect wildlife and human communities.

SNAMP – funded with $15 million in grants mainly from the U.S. Forest Service, with support from U.S. Fish and Wildlife, California Natural Resources Agency and University of California – ran from 2007 to 2015. The project ended with the submission of the final report that contains details about the study areas, the treatment processes and reports from each of the six science teams. The science teams and their final reports are:

A key chapter in the publication is titled Integrated Management Recommendations. In it, the 31 points of consensus are outlined.

“The integration in this project is also unique,” Susie Kocher, CE advisor said. “Scientists tend to work in their own focus areas, but we can learn a lot from each other's research projects.”

Wolf Hall meets GIS: Mapping musings for the holidays

The great Mark Rylance in character of Thomas Cromwell, from the BBC. I realize this is not the real Cromwell, but Rylance is way easier on the eyes.There are so many reasons I keep returning to Hilary Mantel's Wolf Hall. The book to me seems infinitely revealing, I keep hearing new details. I also managed to use a quote from the book's dialogue in a faculty meeting this year, so there. She comments on history, art, science, collaboration, violence, power, love, politics, craft, cooking, and family. And of course, also mapping. Maps are mentioned many times through the book. At the end, Mantel has Thomas Cromwell say:

"But the trouble is, maps are always last year's. England is always remaking herself, her cliffs eroding, her sandbanks drifting, springs bubbling up in dead ground. They regroup themselves while we sleep, the landscapes through which we move..."

Lovely stuff! and a great holiday read (or re-read, or re-listen). It reminds us that mapping is a continual effort, a continuous process. All that we map changes: crops are harvested and fields are replanted, cities evolve, forests burn and re-grow, and people move across the face of the earth leaving traces. Our task is to capture in virtual space the key functional elements of space and time - through maps, through spectral reflectance and lidar, through text and discussions - so that we can find answers to to the key questions facing society today. It can also be very personal effort: mapping is mostly concerned with finding the best way to represent and describe a landscape or process that we love and want to understand better.

GIS Day Wrap Up (a bit late...)

GIS Day 2015! Happy 10th Birthday to the GIF! 

Panel of mapping innovators @ GIS Day 2015

A quick look at the past decade:

The GIF began in November 2015 on a wave of excitement around geospatial technology. In the months leading up to our first GIS Day in 2005, Google Maps launched, then went mobile; Google Earth launched in the summer; and NASA Blue Marble arrived. Hurricane Katrina changed the way we map disasters in real time. The opening up of the Landsat archive at no-cost by the USGS revolutionized how we can monitor the Earth's surface by allowing dense time-series analysis. These and other developments made viewing our world with detail, ease, and beauty commonplace, but these were nothing short of revolutionary - spurring new developments in science, governance and business. The decade since then has been one of intense innovation, and we have seen a rush in geospatial technologies that have enriched our lives immeasurably.

As 2015 ends we can recognize a similar wave of excitement around geospatial technology as we experienced a decade ago, yet one that is more diverse and far reaching than in 2005. This GIS Day we sought to highlight the societal benefit derived from innovators across academia, non-profits, government, and industry. 

GIS Day/GIF 10th Anniversary

On November 18 we co-hosted GIS Day with BayGeo (formerly BAAMA) as we have in the past and had well over 180 attendees. Our GIS Day featured posters, lightening talks, presentations, and a panel session that included local innovators from Bay Area Industry, Government, and Non-Profits. Our panel speakers included: Cindy Schmidt (NASA); Gregory Crutsinger (3D Robotics); Karin Tuxen-Bettman (Google); Ken-ichi Ueda (iNaturalist); Sara Dean (Stamen Designs); Jeffrey Miller (GeoWing); and Kyle Brazil (Urthecast). The discussion included what skills they look for in recruiting and where they see the geospatial world going in the next 5 years. It was a fun evening and personally, I learned a ton. Many levels of appreciation go out to those who spoke, those who came, and those who helped make the day happen.

Hold the date! January 15th for a workshop on Open Tools with ESRI

On January 15th we will hold a full day free workshop on Open Mapping Tools using ESRI. 

Welcome to the Esri GeoDev HackerLab. This is an eight-hour, mentored, hands-on lab for developers (novice or experienced) where you will learn how to build maps and apps for the web, devices, and desktops using ArcGIS and other technologies. 

Here is what we will cover:

1. A brief intro to ArcGIS Online for developers. Get the free dev subscription and we put the tools right into your hands.

2. Data: Search, find, connect to, import, edit, collect, translate, convert, and host datasets and web services. You will also use a variety of cloud-based geoanalytical tools to make better sense of the data and export new datasets for your apps to use.

3. Design: Create web maps tailored to the needs of your end users using layer selection, thematic rendering, popups, and more.

4. Develop: Build customized apps with or without code, using templates, builders, APIs, and SDKs, from Esri and from other popular open source technologies.

The labs are divided into modules that you can do in any order. Choose ones you want to learn, and skip those you already know. You can bring your own data or use tutorial data that we provide. Use web maps of your own or build ones on-site during the lab. If you are a coder, dig into APIs and SDKs from Esri or compatible open source libraries. If you aren’t a coder, you can still build highly customized production-ready apps using templates and builders.

The tutorials are going to be led by developers from Esri, who will either guide you along the way or assist you as you choose your own learning path. 

Stay tuned for sign-up information!
