AgendaAgenda
• Introduction• Background and context• Key features• Materials and methods• Simple scenario involving several queries• User experience considerations• Challenges• Difficulties• What’s next• Short sample video and Q&A
IntroductionIntroduction
• Growing interest in payment for environmental services (PES)
• Range of options, opportunities and possibilities not widely known.
• Where is deforestation likely to occur in the future? Where might a project to be successful?
• An online tool to investigate deforestation and the economics of reducing it in the Amazon.
Background and ContextBackground and Context
• Activity of project: "Strengthening the Amazon Initiative Consortium for Sustainable Use of Natural Resources“
• An instrument for regional inter-institutional collaboration aimed at development and implementation of studies and practices suited to strengthen conservation and rational use of natural resources in the Amazon
Key featuresKey features
• Satellite imagery and geographic information on population density, biodiversity, biomass, land cover and sustainable development in the Amazon
• Calculates rates of past and future forest loss
• Estimates opportunity cost of Reducing Emissions from Deforestation and Forest Degradation (REDD) in user-defined areas
Material and methodsMaterial and methods• Hardware: servers and networks
• Software: ArcGIS Server, DOJO, REST
• Data: remote sensing and GIS
• Methods: satellite image interpretation, spatial overlay (zonal operators), calculation of deforestation rates and economic opportunity costs
• Human resources: server administrator, GIS specialist, developer, geographer, economist

CIAT/TNC (Development AML script to calculate accessibility in South America. It consists of 3 general processes: a) Estimate travel times on land and transportation surfaces b) Reduce travel times where slope and elevation are obstacles to travel and c) Calculate the "cost distance" between any point on the surface and all target cities)

What are some user needsWhat are some user needs
• Download underlying data sets
• Know more details on the base map and data layers
• Visualize other layers such as soils, precipitation, updated satellite images, among others
• Query by Biodiversity
• Import a predetermined shapefiles of an area of study
• Display current and future distribution of endemic and threatened species
• Access Portuguese version and video tutorials for each tool or module
Developer experience
• Key objective is to make it simple
• Opportunities for improvement come from working with just a few interested users
• The details are all important
• A lot of alphanumeric and geospatial information to show the users in a reduced space
Challenges
• Deal with regional to local scales to represent the real deforestation
• Continuous generation of cache maps and techniques to speed up the results at different scales
• Deal with several geographic and design tools to distribute an effective web-mapping application
DifficultiesDifficulties
• Consistency between browsers is difficult to achieve
• Many people in the Amazon still do not have sufficient bandwidth to use these types of tools
• Speed of application remains a concern: Flash is one possible solution
What’s nextWhat’s next
