About RIGIS

The Rhode Island Geographic Information System (RIGIS) is an consortium promoting the interests of Rhode Island's geospatial community. This group of government and private organizations promotes the use of the latest technology as a means for managing and utilizing a comprehensive database of geographically-related (geospatial) information. The mission of RIGIS is to monitor, coordinate, and provide leadership for activities relating to the use of GIS technology within Rhode Island, to support initiatives that implement or use GIS technology, and to provide easy access to an extensive database of geospatial data for the state. By making this comprehensive collection of geospatial data widely available, RIGIS has become a leader in the United States as an open geospatial data clearinghouse.

Through the promotion of a geographic information system (GIS), RIGIS is able to encourage individuals, private businesses, local and state government, K-12 institutions, and colleges and universities to invest in a staff with GIS expertise, the required technology (hardware and software) as a means for enhancing decision-making through the utilization of land-related information such as that provided by RIGIS. When used successfully, GIS can capture, store, manipulate, analyze, manage and present all spatially related data in a variety of ways for any number of disciplines.

RIGIS History

The Director of the Rhode Island Department of Environmental Management (RIDEM) started the precursor to the RIGIS in 1985. He did so by initiating an agreement between that state agency and the University of Rhode Island (URI) to establish a GIS for the management and analysis of environmental data in Rhode Island. The RI Department of Transportation (RIDOT), the RI Statewide Planning Program, and the RI Solid Waste Management Corporation (now RI Resource Recovery Corporation) joined this effort shortly thereafter, each supporting the concept of a unified, centrally managed spatially related data base. Overall coordination was accomplished through an informal committee of top level management from each of these five organizations meeting on an ad hoc basis. Technical management of the data base resided at the University of Rhode Island. The RIDEM provided all funding for operations at the Environmental Data Center (URI/EDC) at the University through 1989.

The RIDEM provided a system coordinator from within that agency until 1989. This person organized GIS related activities within RIDEM, and acted as a staff liaison person, primarily between the RIDEM and the URI/EDC. The coordinator also provided staff support for an ad hoc inter-agency management committee. The Solid Waste Management Corporation funded the system coordinator from 1989 through 1991 using a contracted consultant to fill this role. This coordinator was supported by staff and facilities at the Department of Administration's Division of Planning. Duties included liaison functions between the four state agencies, (RIDEM, RIDOT, RISWMC and RIDOA-DOP), and the University of Rhode Island, as part of staff support functions for the RIGIS Executive Committee, the successor to the previous ad hoc group. In 1991, a GIS Manager position was established at the RIDOA, Division of Planning. This person was funded from within that Division's operating budget and assumed the duties of the RIGIS Coordinator. Responsibilities were expanded to include administration of the data distribution system, and liaison among public and private sector organizations with interests in GIS and related technologies.

From the beginning of development of GIS in Rhode Island in 1985, each of the primary four state government organizations involved supported their own internal GIS efforts. Similar methods for internal operations were employed at the Environmental Data Center at the URI. Funding through grants on specific projects from the agencies assisted in the development and operations of the EDC Laboratory. This included the purchase of computer hardware and software, the assignment of operating personnel, and funding for data development for information applicable to each agencies' or institution's needs. Realizing the benefits of a collective informational source, these organizations contributed their data into a common RIGIS database. Early on, the Rhode Island office of the USDA/SCS (now NRCS) and the Narragansett Bay Project also significantly contributed to the data base development effort. Initially the RIGIS database was housed at the Environmental Data Center at URI. Until 1991 the EDC/URI used internal staff to perform data base management functions including assimilation of data, cataloging and distribution. The staff positions were funded through contractual arrangements with the RIDEM and by grants awarded by the RISWMC. Due to shortfalls at the RIDEM in 1990 and 1991, the University was forced to contribute funds from its own budget to partially support this effort. The URI/EDC ceased data base management functions in 1991, and these responsibilities were, by default, assumed by the RIGIS Coordinator at Statewide Planning. At that time, all external data distribution duties were also shifted to the Division of Planning.

Legislative Establishment

In 1990, legislation was introduced and passed by the state legislature to modify and amend the General Laws of Rhode Island to include language pertaining to a state wide geographic information system. Chapter 42-11-2-(v) which is focused on the RI Department of Administration now states that the Department shall have the powers and duties to "devise, formulate, promulgate, supervise and control a comprehensive and coordinated statewide information system"...that ..."may include a Rhode Island geographic information system". Under Chapter 42-11-10-(f)-(6) pertaining to the Statewide Planning Program, the State Planning Council will "establish and appoint members to an executive committee consisting of major participants of a Rhode Island geographic information system with oversight responsibility for its activities." This Chapter also states "In order to ensure the continuity of the maintenance and functions of the geographic information system, the general assembly may annually appropriate such sum as it may deem necessary to the department of administration for its support." Furthermore, this Chapter states under 42-11-10-(g)-(3) that "the Division of Planning shall manage and administer the Rhode Island geographic information system of land related resources, and shall coordinate these efforts with other state departments and agencies, including the University of Rhode Island, which shall provide technical support and assistance in the development and maintenance of the system and its associated data base."

The same legislative package added language to the General Laws for the University of Rhode Island under Chapter 16-32-30 whereby, the University was "authorized and empowered to establish in connection with the University and within the Department of Natural Resource Sciences a geographic information system laboratory with suitable facilities for developing and maintaining a level of scientific and technical expertise in the use of computer technology in the management of land-related natural resources. This will include maintaining a statewide data base of land related economic, physical, cultural, and natural resources and providing for controlled access of this data base to the university community; other state, municipal and federal departments and agencies; and the general public...The University shall cooperate with and provide technical assistance to the Division of Planning of the Department of Administration in the management of the statewide geographic information system and shall advise other state, municipal and federal departments and agencies and the general public in its use." A separate section addresses the University's authorization to fund the GIS laboratory under 16-32-31. Appropriations for geographic information system laboratory. - "The general assembly may annually appropriate such sum as it may deem necessary for maintaining the geographic information system laboratory within the department of natural resource sciences, and the state controller is hereby authorized and directed to draw his or her orders upon the general treasurer for the payment of said sum, or so much thereof as may from time to time be required, upon receipt by the controller of properly authenticated vouchers."

Data Distribution Policy

The following Data Distrubution Policy, written in September of 2014, replaces the original 1989 RIGIS License Agreement.

Background Information

Since its inception in 1985, the Rhode Island Geographic Information System (RIGIS) consortium has served as the custodian and distributor for a collective database that now represents more than 175 individual geospatial datasets and data collections.

A data license agreement was implemented by RIGIS in 1989. The intent of this agreement was to help protect the intellectual property of those who contributed data to RIGIS for publication and distribution, as well as to limit liability from potential misuse of these data.

In recognition of open data distribution policies now encouraged by both federal and state government, the RIGIS Executive Committee decided to retire the RIGIS license agreement (view the proclamation). Effective September 1, 2014, the RIGIS license agreement was superseded by the following open data distribution policy:

RIGIS Data Distribution Policy

All data distributed by RIGIS are provided 'as is.' The producer(s) of these data, contributors to these data, the Rhode Island Geographic Information System (RIGIS) consortium, the State of Rhode Island, and the University of Rhode Island do not make any warranties of any kind for these data, and are not liable for any loss or damage however and whenever caused by any use of these data.

Please acknowledge both RIGIS and the primary producer(s) of these data in any derived products. Versions of the RIGIS logo suitable for both printed and web-based products are available at our logo depot.

Data Distribution Policy Implementation

With the September 2015 launch of this new RIGIS website, the previous 1989 license agreement has been phased out. Please rest assured that any data obtained via RIGIS are now shared under this new open data distribution policy, not the license agreement.

If you would like to view the previous license agreement, please reference the FAQ page.

 

RIGIS Executive Committee

The Rhode Island Geographic Information System (RIGIS) Executive Committee provides policy guidance, oversight, and coordination of the collective efforts of organizations in Rhode Island using GIS technology. It seeks to coordinate data development, adopt technical standards, set distribution policy for GIS products, promote the use of GIS, and provide information and assistance to users.

What are geospatial data?

geospatial
/ˌjēōˈspāSH(ə)l/

adjective
1. of or relating to the relative position of things on the earth's surface
2. pertaining to the geographic location and characteristics of natural or constructed features and boundaries on, above, or below the earth's surface; especially referring to data that is geographic or spatial in nature.

All data available for download from RIGIS is tied to real locations throughout the state of Rhode Island, and represent either natural or manmade features that can be found within our state. Some of the data available for download also represent what could happen sometime int he future; the scaled Sea Level Rise data is a great example of this type of "predictive" geospatial data.

 

 

 

How do I use this website?

This site is divided into three sections - Data, Maps, and Information.

The Data page catalogs RIGIS data into numerous common-sense categories, such as "Biology and Ecology", "Hydrology", and "Transportation", making it easy to search and download. Each dataset is accompanied by a brief description within these larger categories, however each dataset also has it's own more detailed description that can be accessed by clicking the dataset title. This description page will allow easy sharing of datasets as these page URLs will remain constant as a dataset is updated. The majority of data is available as Esri shapefiles, which are supported by most opensource GIS software.

The Maps page provides links to web resources from government, non-profit and private organizations boasting pre-made paper maps or web-based mapping applications. Using the "Filter by Category" on the right side of the page, users can sort these resources by a variety of useful topics, such as parcels, static maps, recreation and dynamic maps, helping to sort through the myriad of resources available. The Maps page is ideal for anyone interested in viewing or using maps, but who don't have access to GIS software.

The Information page provides users with information about RIGIS, information on how to get in touch with us, a detailed FAQ, and lots of other useful resources for the GIS (and non-GIS) community. Under the Contact Us portion of the website, you will find a quick survey form that can be used to provide feedback on the website, our data, or can be used as a way to provide suggestions on how this site can be improved for you.

To quickly search and find data, or maps use the Search bar located at the bottom of the page. Type in any keyword, such as "sea level rise" and all relevant information on the site will be returned. This makes it much easier to search through our 200 vector datasets and over 20 imagery, LiDAR and base map collections.

 

If I have a question about a specific dataset, who should I contact first?

For questions pertaining to specific datasets, please first contact the Point of Contact (PoC) listed in the metadata record under the “Identification Information” section for that dataset. The person listed as the PoC will have the most comprehensive knowledge about that dataset.

Alternatively, please feel free to contact Erica Tefft, the RIGIS Data Manager, at erica@edc.uri.edu or at 401-874-5054 with any questions, comments or concerns.

What projection does RIGIS use for its data?

RIGIS uses the Rhode Island State Plane (feet) North American Datum of 1983 projected coordinate system, unless otherwise specified. See below for projection details from Esri's ArcMap.

What are the horizontal units of the data I downloaded?

Typically, units are in feet due to the projection used by RIGIS. This may not be the case if another projection is specified (see FAQ regarding projections on RIGIS).

Are parcel data available on RIGIS?

No, parcel data requests must be made directly to the municipality in question. There are three options for finding parcel data:

1) Select the appropriate municipality from our Municipal GIS Resources page.

2) Visit our Maps section and use the "Filter by Category" to filter by "parcel". This will display all municipalities where parcel data is available. A link directly to the municipal GIS website is also provided.

3) Search for a town using the Search function at the bottom of the page. This will bring up the information on the town GIS website, available from our Maps section.

Are voting districts (precincts) available on RIGIS?

At this time, no municipal voting district or precinct data are available via RIGIS.  

Those who are interested in obtaining these data must contact each municipality individually with such requests. For a list of options on accessing municipal data, please reference the parcel FAQ.

What are all of those files contained within a shapefile (SHP) .ZIP?

An ArcMap Shapefile (SHP) consists of 6-8 different individual files (.cpg, .dbf, .prj, . sbn, .sbx, .shp, .shx, .xml). These will all have the same file name and need to be located with the Shapefile in the same directory.

Mandatory Files
       - .shp: the feature geometry
       - .shx: a positional index of the feature geometry contained with the .shp
       - .dbf: attribute information

Other Files
       - .prj: coordinate system and projection information
       - .sbn & .sbx: a spatial index of features
       - .cpg: used in conjunction with the .dbf
       - .xml: metadata, usually in the FGDC metadata format, although there are other formats

What is a .ZIP file?

A .ZIP file is a compressed binary file format that utilizes lossless data compression. .ZIP files were developed to expedite file transfers, and to serve as an archive file format. A .ZIP file will contain one or more individual files within it.

How can I stay up-to-date on happenings in the RIGIS user community?

There are a few ways to stay up to date with the RIGIS user community!

         1) Join our email listserv RIGIS-L - this is great way to stay in touch with happenings within the RIGIS user community.

         2) Add the RIGIS Event Calendar to your Google Account!

         3) Follow us on Twitter at @RIGIS

How do I access map & image services featuring RIGIS data through ArcMap?

To access Map & Image services in ArcMap, follow the following instructions:

1) Click the arrow next to the Add Data button to expand the menu.

2) Select Add Data from ArcGIS Online...

3) In the search bar, type in RIGIS. This will display all available map and image services hosted by the University of Rhode Island Environmental Data Center. To get more details about an item, click Details; to add to your ArcMap document, click Add.

NOTE: Services containing authoritative RIGIS data will be posted by the account URIEDC_RIGIS. Please look for this when selecting data.

 

How do I efficiently download many tiles of imagery data?

To download imagery in bulk, utilize a bulk download tool such as DownloadThemAll!

How do you recommend citing data obtained from RIGIS within an academic paper or professional report?

Use of a professional or academic publication standard is encouraged, such as the ASPRS Photogrammetric Engineering & Remote Sensing (PE&RS) standard.

Using this format as an example, a citation for an individual RIGIS dataset might follow this example:

RIGIS, 2015. Rhode Island Senate Districts; senateDist13r2. Rhode Island Geographic Information System (RIGIS) Data Distribution System, URL: http://www.rigis.org, Environmental Data Center, University of Rhode Island, Kingston, Rhode Island (last date accessed: 18 August 2015).

And a citation for the collective RIGIS online database might be:

RIGIS, 2015. Rhode Island Geographic Information System (RIGIS) Data Distribution System. URL: http://www.rigis.org, Environmental Data Center, University of Rhode Island, Kingston, Rhode Island (last date accessed: 18 August 2015).

Can I get official RIGIS logos to use on my maps?

You've found the RIGIS Logo Depot, intended to be one-stop shopping for your RIGIS logo needs. Below you will find graphics appropriate for web and print use, graphical usage guidelines, and the original vector artwork in case none of the images suit your needs.

Reminder: your usage of RIGIS data is must abide by the terms of the RIGIS license agreement, which includes acknowledging RIGIS as a data source. This is commonly accomplished by including the RIGIS logo in your publication, or using text to simply list RIGIS as a source.

How do I view MrSID images?

MrSID (Multiresolution Seamless Image Database; *.sid) is a proprietary image format owned by LizardTech. This format is known for its capacity to greatly reduce (compress) image file sizes, with only minor sacrifices to image quality when compared to the traditional GeoTIFF format.

After downloading a MrSID formatted image from RIGIS, you may need to install some software to view the file. If you are not a GIS user, our recommended viewer is either GeoViewer (standalone software for Windows) or the ExpressView Browser Plug-in for Windows, or GeoViewer for iOS, both available from LizardTech. These software perform well, and also may be used to view the MrSID compressed images RIGIS distributes.

Please email us if you find other useful, free software that display MrSID formatted images!

Users are encouraged to explore the offerings available in the RI Digital Atlas; this online atlas hosts viewable web maps of all our historical imagery collections (and much more!). Using the services provided by the RI Digital Atlas is a great way to incorporate historical imagery into your ArcGIS Online or ArcMap document.

What is the difference between a GeoTIFF and a JPEG2000 (JP2)?

A GeoTIFF is a lossless geospatial file format, typically resulting in large file sizes.

A JPEG2000 (JP2) is a geospatial file format available as either lossy or lossless, and offers highly compressed file sizes.

Other Technical Standards

The standards presented below, represent a variety of widely accepted standards used for geospatial data. While these standards are industry standards, they have not been endorsed by the RIGIS Executive Committee.

 

ASPRS Positional Accuracy Standards for Digital Geospatial Data - Edition 1, Version 1.0, November 2014

"The objective of the ASPRS Positional Accuracy Standards for Digital Geospatial Datais to replace the existing ASPRS Accuracy Standards for Large-Scale Maps(1990), and the ASPRS Guidelines, Vertical Accuracy Reporting for Lidar Data(2004) to better address current technologies.

 

This standard includes positional accuracy standards for digital orthoimagery, digital planimetric data and digital elevation data. Accuracy classes, based on RMSE values, have been revised and upgraded from the 1990 standard to address the higher accuracies achievable with newer technologies. The standard also includes additional accuracy measures, such as orthoimagery seam lines, aerial triangulation accuracy, lidar relative swath-to-swath accuracy, recommended minimum Nominal Pulse Density (NPD), horizontal accuracy of elevation data, delineation of low confidence areas for vertical data, and the required number and spatial distribution of checkpoints based on project area." ASPRS Positional Accuracy Standards for Digital GeoSpatial Data, p. 3.

For more information on the ASPRS standards, please visit their Standards information page.

 

Federal Geographic Data Committee (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM)

"The objectives of the standard are to provide a common set of terminology and definitions for the documentation of digital geospatial data. The standard establishes the names of data elements and compound elements (groups of data elements) to be used for these purposes, the definitions of these compound elements and data elements, and information about the values that are to be provided for the data elements." FGDC Content Standard for Digital Geospatial Metadata, p.iv.
