Colorado's open spatial data portal

The CT Geodata Portal is an open data site for all geospatial data in Connecticut. Users can find spatial datasets directly administered by the GIS Office as well as those shared by the Department of Transportation, the Department of Energy and Environmental Protection, CT ECO, and other partners.

Have you ever wanted to create your own maps, or integrate and visualize spatial datasets to examine changes in trends between locations and over time? Follow along with these training tutorials on QGIS, an open source geographic information system (GIS) and learn key concepts, procedures and skills for performing common GIS tasks – such as creating maps, as well as joining, overlaying and visualizing spatial datasets. These tutorials are geared towards new GIS users. We’ll start with foundational concepts, and build towards more advanced topics throughout – demonstrating how with a few relatively easy steps you can get quite a lot out of GIS. You can then extend these skills to datasets of thematic relevance to you in addressing tasks faced in your day-to-day work.

A cooperative effort of the Governor’s Office of Administration and Pennsylvania State University Pennsylvania Spatial Data Access (PASDA) is Pennsylvania’s official public access open geospatial data portal. PASDA was developed in 1997 and has severed as the Commonwealth’s geospatial data portal for over 25 years; it is Pennsylvania’s node on the National Spatial Data Infrastructure and is integrated with the National State Geographic Information Council GIS Inventory. Data on PASDA is free to all users and is provided by federal, state local and regional governments, non-profit organizations and academic institutions.

The Open Government Data portals (OGD) thanks to the presence of thousands of geo-referenced datasets, containing spatial information, are of extreme interest for any analysis or process relating to the territory. For this to happen, users must be enabled to access these datasets and reuse them. An element often considered hindering the full dissemination of OGD data is the quality of their metadata. Starting from an experimental investigation conducted on over 160,000 geospatial datasets belonging to six national and international OGD portals, this work has as its first objective to provide an overview of the usage of these portals measured in terms of datasets views and downloads. Furthermore, to assess the possible influence of the quality of the metadata on the use of geospatial datasets, an assessment of the metadata for each dataset was carried out, and the correlation between these two variables was measured. The results obtained showed a significant underutilization of geospatial datasets and a generally poor quality of their metadata. Besides, a weak correlation was found between the use and quality of the metadata, not such as to assert with certainty that the latter is a determining factor of the former.

The dataset consists of six zipped CSV files, containing the collected datasets' usage data, full metadata, and computed quality values, for about 160,000 geospatial datasets belonging to the three national and three international portals considered in the study, i.e. US (catalog.data.gov), Colombia (datos.gov.co), Ireland (data.gov.ie), HDX (data.humdata.org), EUODP (data.europa.eu), and NASA (data.nasa.gov).

Data collection occurred in the period: 2019-12-19 -- 2019-12-23.

The header for each CSV file is:

[ ,portalid,id,downloaddate,metadata,overallq,qvalues,assessdate,dviews,downloads,engine,admindomain]

where for each row (a portal's dataset) the following fields are defined as follows:

portalid: portal identifier

id: dataset identifier

downloaddate: date of data collection

metadata: the overall dataset's metadata downloaded via API from the portal according to the supporting platform schema

overallq: overall quality values computed by applying the methodology presented in [1]

qvalues: json object containing the quality values computed for the 17 metrics presented in [1]

assessdate: date of quality assessment

dviews: number of total views for the dataset

downloads: number of total downloads for the dataset (made available only by the Colombia, HDX, and NASA portals)

engine: identifier of the supporting portal platform: 1(CKAN), 2 (Socrata)

admindomain: 1 (national), 2 (international)

GDAL is an open source translator library for raster geospatial data formats that presents a single abstract data model to the calling application for all supported formats. By providing integration into the GDAL command line utilities, GIBS imagery can be easily included in imagery processing workflows, including bulk access.

"Our map viewer show some of the geological information SGU is able to offer. Using the viewers, you can for example see what areas we have mapped and what types of data we have collected, and get an overall picture of the country’s bedrock, Quaternary deposits and groundwater."

Tags are part of the information, commonly called metadata, that can be added when creating new items, authoring maps and apps, or creating new groups in your organization. They can be added to any item, can be edited, and are a useful way to boost search results and find specific content.Without proper forethought, tagging data will quickly become a subjective process with a mess of inconsistent tags existing within an organization. When sharing data publicly over a multi-organizational open data platform such as the Florida Geospatial Open Data Portal, these tags may be incompatible with tags used by other organizations.This webpage seeks to provide guidance to State of Florida organizations that participate in the Florida Geospatial Open Data Portal by highlighting how tagging data works in the ArcGIS Online platform, providing best practices for getting started tagging data in your own organization, and explaining how tagging works with the Florida Geospatial Open Data Portal.

In the course of the construction of the spatial data infrastructure of the Free State of Thuringia (GDI-Th) selected geodata are made available to internal and external users for free use. From the geobase data of the central spatial data storage and spatial data provision component Geoproxy, data collections of particular public interest are made available to everyone as public data without restriction of access and free of charge via the Geoclient as a viewing service. These are data from the Digital Topographic Map 1:10 000 (DTK10).

The GEOSS Portal is an online map-based user interface which allows users to discover and access Earth observation data and resources from different providers from all over the world. The portal is implemented and operated by the European Space Agency and provides a single internet discovery and access point to the ever-growing quantities of heterogeneous collections of Earth observations from satellites, airplanes, drones and in-situ sensors at global, regional and local scales through the Global Earth Observation System of Systems (GEOSS). The GEOSS is a social and software ecosystem connecting a large array of observing systems, data systems and processing services to strengthen monitoring of the state of the Earth. It facilitates data and information accessibility and interoperability to support the Sustainable Development Goals (SDG) agenda and the Disaster Risk Reduction.

The dataset provides the usage statistics (covering both the number of downloads and the number of API requests) of open data (spatial data included) of the Open Data Portal per data provider in a specific time period

Background

Preventive and health-promoting policies can guide (place and space-specific) factors influencing human health, such as the physical and social environment. Required is data that can lead to a more nuanced decision-making process and identify both, existing and future challenges. Along with the rise of new technologies, and thus the multiple opportunities to use and process data, new options have emerged to measure and monitor factors that affect health. Thus, in recent years, several gateways for open data (including governmental and geospatial data) became available. At present, an increasing number of research institutions as well as (state and private) companies and citizens' initiatives provide data. However, there is a lack of overviews covering the range of such offerings regarding health. In particular, for geographically differentiated analyses, there are challenges related to data availability at different spatial levels and the growing number of data providers.
