The ability of GIS to provide consistent, accurate and accessible quantitative information, makes it well-placed to be a key tool in evidence based decision making and in the formulation of sustainable development policies.
This fact is being recognized by several countries in the Caribbean region and is the main reason for a number of Spatial Data Infrastructures (SDI) initiatives across the region. National governments are recognizing that location information is critical in managing everything that falls within the remit of governing. Like most types of infrastructure, SDIs also provide a platform for economic development and is a key infrastructure in realizing spatially enabled societies; that is, a society that is spatially aware of its environment and consumes spatial information as part of their normal daily decision making and personal life.
Spatial Data Infrastructure (SDI)
A Spatial Data Infrastructure is the “… collection of technologies, policies and institutional arrangements that facilitate the availability of and access to spatial data.” The aim of an SDI is to facilitate the ability of stakeholders to share, access and discover spatial information, and therefore, needs to evolve in tandem with the development of available network technologies (Rajabifard, 2012) [see previous blog on metadata].
Spatial data has traditionally been used by public organisations, businesses and academia. However, there is now a paradigm shift and spatial data is increasingly being used, created and shared by ordinary citizens; and an open data posture with open access to information encourages this paradigm shift. Hence, some aspect of Geographic Information (GI) or Geographic Information Systems – which serves up spatial information for consumption; is used virtually every day. It should not be then difficult to understand that when an infrastructure becomes critical to societal and economic development, national policies must guide its development and implementation. To do otherwise means chaos will reign and maximum benefit will never be realized. In addition, as the SDI facilitates the creation, distribution and usage of spatial data – the access to and availability of such data may be impacted by data accuracy and quality concerns, privacy concerns, intellectual property concerns and appropriate usage concerns. Hence, it is very critical that national SDI or Geographic Information (GI) policies development be at the forefront of any SDI initiative.
Where are the Caribbean Nations in SDI/GI Policy Development?
Within the Caribbean region, there are significant shortcomings in the legal framework that exists to provide effective regulation or even basic guidelines on spatial data matters. Development and implementation of national policies to support Spatial Data Infrastructure is critical for a coordinated effort to standardize the processing of spatial information across governments and other entities and to create authoritative spatial data sources.
Currently there are at least 5 Caribbean States that have pursued or are actively pursuing policy development initiatives – Jamaica, Belize, The Bahamas, Trinidad & Tobago and Guyana. Awareness of the importance of SDI and the development of the requisite regulatory policies has certainly increased in the region. However, there are still a number of Island states which lag behind. While some countries may progress slower than others, all need to be part of the journey towards policy Development and ultimately sustainable SDI.
At the 3rd High Level Forum on United Nations Global Geospatial Information Management held in Beijing, China, October 2014; having met in the context of the United Nations initiatives to enhance cooperation in geospatial information management to support global sustainable development – a resolution was adopted that spoke directly to the matter of formulating and developing sustainable SDI policies. It stated that the group resolved to ‘overcome the challenges in implementing geospatial education and awareness, policy, standards and frameworks by engaging our professional community, industry and research related centres and institutes.’
SDI/GI Policy Development Benefits
Developing Geographic Information Policy will provide the necessary legal framework for the industry to develop and thrive. In turn, the value and importance of spatial information can be realized.
It also will establish the guiding principles and strategies to enhance accessibility, help in developing or promoting geospatial standards, avoid duplication of effort and hence utilise limited resources in the most efficient manner. Further, it will enhance the cooperation and coordination among agencies in identifying and facilitating the development of useful data for research, planning, sustainable development, disaster management, environmental management and climate change among many other areas – an issue recognized as being critical by the US Senate in their Bipartisan Geospatial
Policy development should therefore be our collective concern. How can we move policy development forward within the region? Should we create regional guidelines for developing GI policy? Do our leaders recognize the importance of GI policy?

What is Metadata?
- How a dataset was collected or created
- When it was collected or created
- Location it was collected or created
- Who performed the creation or collection
- How the data is formatted
- Any constraints on how the data may be used
- Data characteristics including content, condition, accuracy and quality.
It is perplexing then, when a GIS department of an organization/entity can simply dismiss metadata creation as being too time consuming. What is further a cause for even greater concern is how an organization would spend thousands of dollars creating datasets but do not ensure that these datasets are delivered with the associated metadata.
There are many benefits to be derived from creating metadata. Among them are the following:
- Protecting an organization's resource investment in data creation
- Creating institutional memory
- Countering personnel changes
- Allows sharing of data with other agencies
- Savings in time and money
- Limiting potential liability
- Cataloging and discoverability
Whatever the reasons, as GIS professionals it is our responsibility to guide the change in current practices. We must become the change agents and find creative ways to educate and influence the decision makers. Metadata creation must become a mandatory standard within the GIS implementation strategies for all organizations. Metadata standards must be adopted!
Going back to the matter of cataloging and discoverability. Automated cataloging of datasets depends heavily on the availability of datasets' metadata. Automation improves productivity and facilitates faster time to decision with less susceptibility to human error. Information systems are now designed with the ability to generate intelligence from the data presented. Metadata deepens that process and enhances the quality of the intelligence produced. Automated discovery of data is facilitated by having metadata conforming to specific standards.
Discoverability facilitates the creation of a vast network of information stores that can grow intelligently because within itself is the ability to discover, create linkages and extend intelligence. The concept of Semantic Web now becomes more real that is “… a common framework that allows data to be shared and reused across application, enterprise, and community boundaries."
We need to get everyone to appreciate that metadata creation becomes less complicated and time consuming when standards are adopted. The focus would then shift to ensuring that standard practices are compliant with international requirements. While there is no single strategy or approach to achieving full compliance, there are some important steps in this process:
- Research the practice of those at the forefront of the GIS industry
- Develop internal metadata standards that complies with recommended best practice
- Develop an organizational implementation plan
- Conduct metadata workshops
- Select appropriate Metadata editing tool
- Require contractors and data developers to adhere to defined metadata standards
In the past, shortsightedness of decision makers has cost the Caribbean region much of its advantages - loosing out to other regions of the world. This is an opportunity to assist in developing and building the Spatial Data Infrastructure of the Caribbean region. Let's not loose it!
It will take an effective metadata strategy involving cooperative efforts, incentives, and new ideas to make metadata part of mainstream activities within the GIS community of the Caribbean region. Can we go beyond organization and countries to creating a metadata profile for the Caribbean region?

Recently, I was facilitating a GIS (Geographic Information System) Training for a utility organization within the Caribbean region. During the training, participants started to speak about the workflows they presently use, the various software within the organization, their having to be converting data between different formats, etc. What became very obvious was that this organization is suffering from software overload, departments operating in silos, segmented workflows, and a clear indication that they need to have a comprehensive Enterprise Needs Assessment and Requirements study done. It was quite apparent that there was an absence of Strategic Information Systems Planning or the implementation of the results of such planning and hence what came out from the participants was quite reflective of the general lack of appreciation of the critical role Enterprise GIS plays within organizations today.
It was dejavu as this is a story I have heard and seen a dozen times across the Caribbean region. Granted, this organization has a GIS unit with desktop GIS software and they produce some maps and reports, but they seem not to appreciate that there were other utility companies within the region where GIS is being used as a critical part of their business processes – from tracking and managing assets, supporting the production and transmission design process, to being used as a key tool in business operations; for example Outage Management, Strategic Capacity Planning and to organize and streamlined inspection and maintenance programs. But even for these organizations, are they there yet? Are these organizations maximizing their investment in GIS and other Spatial Technologies to provide real Enterprise value and benefits?
Let’s look at some of the benefits of incorporating Enterprise GIS as part of the Strategic Information Systems planning within organizations.
GIS has the ability to eliminate inaccuracies and inefficiencies connected with:
- The proliferation of maps and data of differing content, accuracy and forms of representation.
- Duplicative and counterproductive efforts of employee effort in the creation, organization, maintenance, management and utilization of maps and asset data in isolated silos. Instead of efforts focused on keeping one set of data correct, man-hours are wasted keeping several sets of possibly fragmented data.
- Redundant and sometimes conflicting tasks and workflow resulting from the operations of isolated silos resulting in inconsistent or, incomplete maps and asset data.
- Delayed and ineffective decision making resulting from incomplete, or even conflicting views of what the true picture is within the organization.
Enterprise GIS can unify the business processes within organizations – in this case utility companies can present a common operating picture. Enterprise GIS is the sum of the coordinated personnel efforts working in tandem with integrated systems that support and promote geospatial data development and access across an organization. In the context of utility companies; another way of putting it is that an Enterprise GIS exists when spatial data is readily accessible and effectively used in business processes across the organization to:
- Support daily business operations
- Extensively utilized in making critical intelligence driven Strategic Decisions
Over the past few years, the term Enterprise GIS has become more common in the GIS community. This is a clear reflection of the value to be derived at the Enterprise level.
There has also been a number of changes in recent years that is allowing Enterprise GIS to be a much more attainable goal for organizations and particularly utility companies.
- New Technology
- Easier Deployment Options
- Increased Access to a variety of data sources
- Increased demand from consumers for organizations to be instantaneously aware of the state of service delivery at a specific location at a given time
Why would a Utility Organization want to embark on Enterprise GIS? There are many benefits to doing so.
The nature of utilities will always include delivering services over large geographical areas with several departments and units responsible for managing different aspects of service development/production, service delivery and service maintenance. In addition, there is customer billing and payment collections. Often when a large number of assets and resources are utilized in field work and particularly in emergencies, precise coordination via location aware data and systems are critical. So clear benefits include:
- Integrates geospatial data across multiple departments and serves entire organization
- Allows connection to anyone who needs access to GI
- Eliminates data duplication by collecting data once and using many times
- Reduces data maintenance time
- Ability to combine related legacy data
- Improved workflows
- Effective communication
- Enforces data security
- Timely and effective decision making
Utility organizations must come to the recognition then that the traditional GIS implementation is no longer sustainable as it does not deliver the required benefits for utility organizations. Why then are organizations within the Caribbean not readily allocating resources and embracing enterprise GIS?
Enterprise GIS initiatives are dependent on obtaining organizational buy-in and delivering measurable results. Have the GIS practitioners within these organizations failed to win over the decision makers and stakeholders to the benefits of embracing enterprise GIS? Have they failed to quantify the benefits of Enterprise GIS initiatives? Have they themselves made the shift from the traditional siloed mindset and now focused at the enterprise level in delivering strategic value?
