2015 FOSS4G Track: Analyzing Aspen's Community Forest with Lidar, Object-Based Image Analysis, and Open Source GIS Software by Andrea Santoro and Laura Atkinson
The city of Aspen has a diverse and extensive community forest comprised of natural forested areas, street and park trees, yard trees, and riparian corridors. Trees are a key asset to experiencing downtown Aspen. In this study, we utilized several open source GIS software to analyze the tree canopy extent as well as new tree planting areas. Several land cover metrics were calculated using geoprocessing routines across a variety of spatial planning scales including city limits, parcels, and zoning categories. The data informs planning and development, stormwater modeling, education/outreach, and natural areas monitoring. Methods, tools, and results will be presented.
2015 GIS in Colorado: Going Mobile, Aurora Water Empowers Field Staff with Ta...GIS in the Rockies
The City of Aurora Water Department recently purchased 90 tablets to replace the paper mapbooks used daily by the operations and maintenance staff in the field. The initial intent of the tablets was to not only keep the O&M staff up to date on the latest utility changes without having to reprint the cumbersome $400 16’x20’ mapbooks, but also to get GIS data corrections from the field directly into the GIS data. This direct connection between the field staff and GIS data is the most practical way to correct the various location and attribute errors in the 3,000 miles of pipe and 175,000 appurtenances throughout the City of Aurora's water, wastewater and stormwater utilities. An additional benefit to the electronic mapbooks is the ability for the O&M staff to see and track more information about assets than was allowed in a static format. The software application being utilized for the mapbook interface is Esri's Collector for ArcGIS. A number of administrative staff also have licenses on their personal devices so they can refer to specific utility infrastructure while at meetings away from their office. The technology hardware and software has become very affordable which provides an excellent cost/benefit to the purchase.

The USFS Forest Inventory and Analysis (FIA) program provides a systematic protocol for forest field data collection to serve as the census for forest information and support proper management. This wealth of data has been analyzed to provide wall-to-wall spatial GIS coverage of forest carbon estimates across the lower 48 U.S. states to support Greenhouse Gas (GHG) inventory. Through a research agreement and collaboration with the University of Minnesota (UMN), this project provided a 21st century “digital experience and distribution” of the Forest Carbon Estimation in the FIA program rather than static maps and tables by developing an online, mobile/web browser map application (app). This web and mobile software tool enables the public to learn about carbon and how much is stored in a nearby forest. The data is presented to the user interactively on a map along with charts, graphs, and links to related resources. The intended audience is anyone interested in exploring forest carbon information.
The tool is a web browser map application for smartphones, tablets, and desktop use. It primarily works online but also offline with simplified functionality. This provides any range of users with access to the carbon summaries in the field and at the desk. The app also provides education links to NFS carbon assessment whitepapers and FIA protocols.

The June 2012 High Park Fire burned over 87,000 acres of forest and 259 homes to the west of Fort Collins, CO. The fire has had dramatic impacts on forest ecosystems. Of particular concern are its effects on the Cache la Poudre watershed, as the Poudre River is one of the most important headwaters of the Colorado Front Range, providing important ecosystem and economic services before flowing into the South Platte, which in turn flows into the Missouri River. Within a week of the fire, the area received several days of torrential rains. This precipitation—in conjunction with steep riverbanks and the loss of vegetation by fire—caused soil and ash runoff to be deposited into the Poudre’s channel, resulting in a river of choking mud and black sludge. Monitoring the effects of this disaster is critical and requires establishing immediate baseline data to assess impacts over time. Utilizing LANDSAT imagery, GIS layers, and boosted regression trees modeling, the NASA DEVELOP team based at the North Central Climate Science Center at Colorado State University conducted an investigation into riparian, wetland and headwaters modeling within the Cache la Poudre watershed. These efforts produced a preliminary model of predicted wetlands across the watershed, which is currently being refined by field data collection and modeling within three elevation-based “life zones.” The ultimate goal of this ongoing project is to provide important spatial data for land managers and create a riparian and wetlands modeling methodology that can be reproduced throughout the intermountain west region.

The equitable distribution of bike paths ensuring safe cycling are inconsistently planned and evaluated. For residents to fully utilize bikes, it is essential that bike networks equitably serve all urban populations. In the absence of impartial evaluation, the construction of biking infrastructure may continue to perpetuate cycles of disadvantage. By measuring the spatial equity of six urban biking networks using GIS (San Francisco, Chicago, Minneapolis, Madison, Boulder and College Station) and interviewing transportation planners, we demonstrate that equity can play a role in planning. We provide spatial and qualitative analyses revealing varying relationships between urban transport planning and the relative equity of bike networks in major cities.

2018 GIS in the Rockies Vendor Showcase (Th): The Data Driven GovernmentGIS in the Rockies
Today, GIS is not just software. It’s data. It’s people. It’s getting to the answer. Quicker. Data is expanding. More users demand access to information but don’t consume the information in the same way as a GIS professional would. But as curators and managers of geospatial information, GIS professionals are looking to support the entire organizational needs not just those in GIS Departments. The chief information officer is acutely aware of how much geospatial data is being collected; now, how do city and state governments leverage these data for smarter, more effective government services. Here are five pillars of the data-driven government to consider:
1. Extensibility: Whatever the choice, the platform must be customizable for users beyond the GIS department. Knowledge workers need access to geospatial technology too.
2. Usability: GIS is a complex tool. However, today’s desktop platform must be adaptable to many types of workflows.
3. Flexibility: The next generation of geospatial solutions must be ready to support the desktop, cloud, SaaS as well as mobile platforms. GIS must adapt to the user’s preferred IT environment…not the other way around.
4. Compatibility: GIS must work in mixed environments of open source and commercial software and ingest data from myriad sources.
5. Expandability: Can your GIS environment work in the world of big data? Smart cities depend on ingesting sensor data produced at high rates that require geoprocessing on a scale not thought possible until recently.

2018 GIS in Development: Partnerships Lead to Additional Recreational Content...GIS in the Rockies
In 2010, the USGS National Geospatial Program (NGP) began producing the new US Topo map series. The first maps were relatively simple, but quality and content have continually improved. Recreational features, especially trails, are among the most often requested features, but have been difficult to add due to lack of national datasets. Some trails in National Forests were added in 2014. In 2015 the USGS partnered with the International Mountain Biking Association (REI-Adventure Projects) to include trails outside of Federal lands. A pilot project with the National Park Service in 2016 added trails, visitor centers, trailheads, and campgrounds to US Topo maps covering the Great Smoky Mountains National Park. 2018 US Topo maps include trails, trailheads, campgrounds, picnic areas, visitor centers, and other recreation information on selected Federal lands, using data provided by the relevant agencies. Continuing into the future, the USGS is working on partnerships with states and other organizations including The National Map Corps to expand recreational features to non-Federal lands. All such data will be in the public domain and published in The National Map geospatial databases.
2018 GIS in Recreation: Adding Value to Colorado the Beautiful Initiative carrGIS in the Rockies
The main point of this abstract is increasing the value of the current Colorado the Beautiful Initiative through additional data points gathered by mapping the trail systems with the use of unmanned aerial systems and 3rd party software to build the additional data points to be included in the current mapped environment.
I have used Unmanned Aerial Systems and 3rd Party Mapping Software Companies (DroneDeploy, Precision Hawk, Pix4D, and DroneMapper) to build sample data to support my work
I have been able to create sample maps, photos, video of certain trail sections to show how additional data sets can be included to increase the value of the initiative for both the public and government sectors
With the data I have collected, I can discuss several points of interest with the conference. I can show how the data can be utilized to benefit the public sector: Safety, knowledge, and planning and the government sector: trail maintenance, anticipating future problems- heavy traffic areas or lost hikers, plant health - fire danger and erosion, and intersection of multiple agency and private land area issues.
The City of Manitou Springs is planning a creek walk along Fountain Creek, an aspirational goal for over two decades. The question is: how to unite a diverse set of stakeholders with competing interests to agree on a preferred route, that incorporates their values and priorities? The answer was to use geodesign.
Geodesign is a powerful participatory planning method that uses stakeholder input and geospatial analytics to show the possible impact of design scenarios. It gets its strength in two ways: 1) from the diversity of participants—proving the adage that two heads are indeed better than one—and 2) from the power of spatial analytics, which allow the visualization of the world both as it is, and as it could be.
The presentation will focus on how geodesign methods where used to define stakeholder groups, clarify values, and prioritize criteria to help decision makers evaluate planning scenarios. Esri ArcGIS Pro was utilized to develop models—such as bikeability, walkability, ADA compliance, and more—that were used to both visualize and evaluate the impacts of each route segment. The spatial analysis resulted in an innovative solution that addressed both the concerns of both government and public stakeholders.
Attendees of this session will learn how to use geodesign as a systems approach for informed decision-making. More importantly, they will learn how to use spatial technology to guide conversations among diverse stakeholders to come up with plans that people understand and are happy with.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Haight, 2010).
Energy conservation:
Trees lower energy demand
through summer shade and
winter wind block, offsetting
power plant emissions.
Stormwater mitigation:
Urban forests intercept
stormwater, reducing the need
for costly gray infrastructure.
Public health:
Trees diminish asthma
symptoms and reduce UV-B
exposure by about 50% (Shade:
Healthy Trees, Healthy Cities,
Healthy People, 2004).
Crime and domestic
violence:
Urban forests help build
stronger communities. Nature
and trees provide settings in
which relationships grow
stronger and violence is
reduced.
Noise pollution:
Trees act as a buffer, absorbing
up to 50% of urban noise (U.S.
Department of Energy).

5. Data, Data, Data!
• How much tree canopy exists?
• Where are we lacking trees?
• Where can we plant more trees?
• What species of trees are where?
