Description: The City of Raleigh is taking a hybrid approach to implementing geospatial technology to help support existing and future delivery of city services. This session will highlight several specific challenges the city has faced/is facing and corresponding solution sets that have been considered/implemented. Specific attention will be a paid to the influence and role of open source software, open source culture, and open data.
Government Use of FOSS4G
It is best to prepare for the disaster that never happens. Richland County, SC did not have the luxury of practice before disaster struck. However, during a recent flood event, previous migration to a cloud-based open source stack for data dissemination provided real-time situational awareness for first responders, recovery teams, County staff, and citizens. In addition, the geospatial contributions of corporate citizens were executed efficiently using open source imagery processes.
Australia’s NationalMap, nationalmap.gov.au, is an engaging, open-source web site enabling the public to discover and explore Australian government spatial data at the federal, state, and local levels. An interesting feature is that NationalMap does not host any data itself. Instead, it provides a federated interface to the diverse servers already operated by the the various government agencies, running Geoserver, THREDDS Data Server, ArcGIS Server, CKAN, Socrata, and many more.
Looking for an open source geospatial platform with versioned web editing capabilities built for your enterprise? Look no further than GeoSHAPE, a FOSS project empowers organizations to create, edit, share and visualize information through dynamic, collaborative web maps. GeoSHAPE has been built utilizing open source software and open standards to make it available for partners and to maximize interoperability.
Metadata is important. Metadata is useful. Metadata is a pain in the butt. Metadata presents a special challenge to highly productive, publicly accountable, decision-driven organizations such as state and local governments. The fiscal restrictions and high demand placed on these data shops require maximum efficiency and effectiveness. As such, the operational focus is on the production, validation, and distribution of data with little time available to document data in a standardized and robust manner.
North Carolina's geospatial community and state as a whole has greatly benefitted from having a culture of free and simple access to a large amount of local and state data, thanks to a lot of hard work and collaboration on a number of initiatives.
As geographic vector datasets continue to become more commonplace and available to the public, GIS users find they routinely work with maps that can vary in format, coverage, attribute schema, completeness, and accuracy. Often times the solution is to work with parts of each dataset in order to produce a superior “best-of-breed” conflated map that leverages the best features and information from each of the individual sources.
The US Topo topographic 7.5 minute quadrangle maps are one of the most popular products produced by the National Geospatial Progam of the USGS. The newest version of the US Topo is packaged as a layered GeoPDF which is available through the USGS's nationalmap.gov. Though the layered GeoPDF may be convenient for the layman, the nationalmap.gov is always receiving requests for other, more versatile raster formats.
To support our oblique imagery acquisition, we have developed an open-source heads up display for our pilots. The system utilizes a number of open tools and data such as: GPSD, PHP, OSSIM, MapBox GL JS API, TileServer, USGS National Map and Open Street Map. The system takes a realtime GPS stream and image collection information from the cameras to generate vector overlays the pilots can use to navigate and tracks progress to ensure full coverage of the survey area. This strategy has vastly improved the the efficiency with which we can collect imagery.
The U. S. Census Bureau created the Geographic Update Partnership Software (GUPS) to assist its partners in the review and collection of geospatial data for the 2020 Census. The GUPS is free software to over 40,000 state, local, and tribal governments, and it is critical for the acquisition of our partner's boundaries, streets, and addresses. The GUPS consists of a suite of Python-based plugins operating within QGIS .
