The Change Matters viewer from Esri can show how your area has changed over a given time period, say for instance, from 1988 to 1990. Las Vegas is known for its phenomenal sprawl over the past four decades. Time-lapseimages from the Landsat earth monitoring satellites reveal in false-color, multispectral imagery how urban sprawl has stretched out from Nevada’s “Sin City” over the past four decades.
This latest video was posted by NASA in honor of the 28th anniversary of Landsat 5’s launch on March 1, but the pictures actually go back to 1972, when the Landsat program began.
This past week, 3500 people attended the Esri Federal GIS Conference held in Washington, D.C. Attendees came from virtually every federal agency, nongovernmental organizations (NGOs), GIS companies and other agencies that support federal and state agencies.
Esri president Jack Dangermond kicked off the plenary with a reminder that the world is rapidly changing and we are confronted with new issues such as loss of biodiversity. GIS helps to build intelligence about these issues.
“If we take raw data we can turn it into information by mapping it, that’s why it’s so exciting to look at maps,” said Dangermond. “And now with the dawning of the cloud web world pattern for GIS we’re seeing how we can share this knowledge and create better understanding. GIS drives understanding.”
Some user work was showcased such as the first global dataset of biomass – in Woods Hole, and the relationship between hydrology and biofuels.
Presenters focused on topics such as integration, collaboration and breaking down government silos.
U.S. ethnic and racial diversity maps are available from Esri between 2000 and 2010 and show that between those years, diversity increased most dramatically.
According to Esri, a Census Bureau index measures diversity from zero to 100. The diversity score for the U.S. in was 49 in 2000, which means there was a roughly 50 percent probability that two people randomly chosen from the population belonged to different race or ethnic groups. Hispanics, which totaled 35.3 million in 2000, accounted for a significant proportion of this overall diversity.
Social Media and Authoritative Citizen Data
Crowdsourced data, initially met with skepticism and concern by the geospatial community, is now going mainstream. GIS practitioners have long been the keepers of “authoritative” data, and are now beginning to take crowdsourced data very seriously. This is in large part due to the tremendous utility of crowdsourced data we’ve seen during responses to recent disasters. Crowdsourced data enriches GIS, and Esri is constantly looking at how our users can use, manage, interpret, and incorporate it into their work.
With the advent of cloud computing as a new platform, geospatial applications in the cloud are driving a powerful new modality for GIS. With it, there is an opportunity to reinvent the way the GIS application is built and consumed, as well as influence the discovery and availability of spatial data and geospatial analyses.
Cloud computing provides the potential for access to and publication of dynamic data. This includes the consumption of real-time information for analyses and modeling, which can then be leveraged in applications that serve multiple purposes and audiences. Esri is seeing this more with disaster response operations that are standing up mission-critical geospatial applications hosted in the cloud. With access to seemingly unlimited compute capacity using cloud infrastructures, analytical calculations can be performed in a fraction of the time as traditional processes, which may potentially offer more economic viability as a result of the economies of scale that the cloud affords.
This may seem only attractive to small- to medium-sized businesses, educational institutions, non-profits, and startups. But as cloud computing moves increasingly into mainstream operations for business, the potential for cloud-hosted content and cloud-delivered content is becoming a significant reality for organizations, regardless of size. For a geospatial technologist, cloud GIS can ideally mean that data is always available, always accessible. For the mobile worker, the cloud offers an expansive field to speed workflow productivity and collaboration. Shared data and applications in the cloud can be immediately accessed to discover, view, edit, save changes and invoke geoprocessing functions for on-demand results.
Esri recognizes the opportunities that cloud computing can afford the geospatial professional and technologist. As such, we intend to continue to invest significantly in research and development of cloud-based solutions and services across multiple vendors to satisfy the requests by the geospatial community, and to foster growth of GIS into industries and within communities that may have not been cultivated as yet.
It is important to underscore that our current attention to the cloud does not forego interest and investment in on-premises desktops, servers and mobile applications. Rather, the cloud is another enabling platform to help complement and augment an organization’s sales, marketing, and technology portfolio capabilities.
Business Intelligence and Analytics
Commercial/business applications of GIS have long lagged behind more traditional GIS applications such as planning, government, and environment. But we are starting to see GIS reach much deeper into the business arena due to the focus on integration of GIS with enterprise resource planning (ERP), business intelligence (BI), data warehousing, and enterprise content management (ECM) applications. The majority of these integrated applications let end users work either in their business application environment or the GIS environment, so they are not disruptive to existing enterprise workflows.
Esri’s approach in this arena has been to partner with companies who have deep expertise in their respective BI, ERP, and ECM environments. We also recently acquired SpotOn Systems, a company that brings interactive mapping to IBM Cognos business intelligence applications. By making it easier to unite Esri’s spatial analytics, data, and maps with IBM Cognos BI, we think that this acquisition provides business users of GIS with the analytic element that has long been missing.
For those who have made any changes to the default raster type, you will probably want to save your changes. This way you can re-use your custom raster type if you want to load additional raster data with the same properties and functions.
To save your custom raster type, click on the General tab. At the bottom of this tab, you will see a Save As button. Click the Save As button, and save it in the location where you keep all your custom raster types.
This timeline from Esri charts the sequence of primaries and caucuses that ends in Utah on June 6. State summaries include a political attitudes spectrum. Despite deepening partisan divisions, the mix of liberal and conservative viewpoints is surprisingly uniform across the nation.
Dr. Map from the UC Santa Barbara Geography Department recently came across the extraordinary Metro Wine Map, designed by architectural historian and wine buff, Dr. David Gissen.” This map covers the French wine districts, and the “appellations.”
“The twist is that the map uses the technique pioneered by Harry Beck in the 1930s for the London underground map. Wine districts are colored “lines,” with branches showing the different appellations. One can clearly see, for example the link between Pouilly-Fumé and Vouvray, both from the Loire Valley, but with the former made from the Sauvignon Blanc grape variety and the latter Chenin Blanc.”
According to Esri “the Infrastructure Network Editing template is an ArcGIS 10 editing map and toolbar for managing water, sewer and storm water utility data. (http://bit.ly/bQONZD)
It is an editor that can be used by mapping technicians in a water utility, sewer authority or public works department. You can configure the Infrastructure Network Editing Template in your environment and in doing so, you’ll learn how to update and maintain water, sewer, and storm water data using ArcGIS Desktop and your organization’s data. To complete the configuration, you will need experience with editing workflows in ArcMap.
This template includes the following:
An editing toolbar, reporting toolbar, a set of constructions tools, and an editor extension that is added to your ArcInfo or ArcEditor installation
A multi-scale ArcMap document designed for editing
The Local Government geodatabase with sample data from the City of Naperville, Illinois
The Infrastructure Editing toolbars contain a series of custom editing and reporting tools that improve the editing experience for ArcGIS users working with infrastructure data. For example, there are tools that:
Automatically connect service connections to laterals and their mains
Report tracing results along the utility network
Graph the profile of a sewer main”
According to Esri, these tools require an ArcEditor or an ArcInfo ArcGIS Desktop License. A multi-user GDB is required if there is more than one editor. If you want to publish services of your water utility data, then an ArcGIS Server Standard or Advance is required.
One month into the Occupy Wall Street protest, the internet is populated with maps depicting activity around the event, not only in the U.S. but in other countries as well. The movement has inspired map makers who may have been headed in another direction, such as Humphrey Flowerdew, who along with his partner, Trung Huynh, both based in London, were originally in business to use their Crafivy to aggregate and map real estate listings.
The Cravify Occupy Wall Street map shows tweets from throughout the world with the hashtags such as #occupywallst, #occupylsx, #occupyrome, #occupytokyo that are frequently updated.
