This type of environmental professional uses geographic data to create a visual record for a general or specialized picture.
What Does a Geospatial Analyst Do?
Geography is one of the most important environmental records we have. It is a rich, detailed and long-term record of how the environment looks now and how it looked in the past. Each day that passes creates more data to harvest, analyze and explain. Geospatial analysis examines elements of geography and the record as a whole, treating a landscape as a monument in itself and as components in the environmental sciences. Geospatial analysts examine a range of data from the geographical record including aerial photographs, GIS data, the cartographic record (which includes old maps, new maps, specialist maps such as soil and geology maps), satellite data, soil analysis and other environmental samples, and any academic literature published about and within the landscape.
This is a useful discipline for those who study geography as a record in and of itself. In archaeology, geospatial analysts examine the historic records and track the development of the historic landscape (urban and rural). In climate science, geospatial analysts will examine changes to the landscape along with the environmental shift. They will look for changes in the biological makeup of a site, signs of the water table, evidence of flooding or drought and how the pollen record compares between now and the past. In resource planning, conservation and disaster relief, they will look at how the record looks now for effective management, to discover potential problems and plan for the future.
Most will split their time between working in office collecting and analyzing data and in the field collection information for processing.

Where Does a Geospatial Analyst Work?
According to data from 2015 acquired for the Bureau of Labor Statistics, the largest employment area for this type of professional is architectural and engineering services with around 33% of employees. This will include urban and regional planning. Construction work, whether building new towns and cities, planning a new mall, extending a residential zone in an existing city will require careful consideration of many elements including environment (whether the land is protected), topography (whether it is physically possible to build there) and the wider landscape. Some 6% work in state government and 4% work in the Federal executive branch for organizations such as EPA.
Local government employs around 26% of this type of professionals. Often, regulation in planning is set by local government. It is their role to ensure that the landscape is viable for development before granting permission to build.
Management, scientific and technical consulting employs around 12% of this type of employee. Outsourcing data collection and processing is a major cost saving for organizations requiring information on which to make any decision about a landscape. As the technology gets cheaper, we expect growth in independent services.
What Is the Average Geospatial Analyst Salary?
The median salary for this type of role according to 2015 data from BLS was $61,880. The lowest earners reported a salary of $39,470 and the highest earners a salary of $98,210. Those with the most experience and skills were likely to earn a higher salary, particularly those with extensive GIS skills. The highest paying area was the small number of Federal employees with $86,740 average. Next was management, scientific and technical consulting with a mean salary of $66,660. Third, and just under the median was architecture and engineering services at $60,770. The fourth was local government with a median salary of $59,510. The lowest-paying area was state government at $57,930.

A geospatial analyst's job description may vary depending on the type of employer, for instance if the analyst works for local or federal government as opposed to for the architectural and engineering industry. Regardless of industry however, at the beginning of his or her career a geospatial analyst would likely take on the following job duties:
- Produce data layers, maps, tables or reports using special analysis procedures or geographic information systems (GIS) technology, equipment or systems
- Study aerial photographs, cartographic record, satellite data, soil analysis and other samples of the environment
- Read current literature, network with industry professionals and participate in professional organizations to keep updated with developments in GIS technology
- Meet with clients to discuss results of geospatial analysis and its impact on land development, construction, environmental conservation or disaster preparedness
- Develop experience using GIS systems as well as specialized engineering or architectural software such as ArcGIS, Quantum GIS, PostgreSQL, PostGIS
- Write presentations and technical reports that communicate analytical processes and results
- Present project and/or research results to a live audience, in person or online
Once a geospatial analyst has accrued several years of work experience, he or she may take on more managerial tasks including:
- Oversee the work and professional development of a team of analysts
- Experience ensuing data integrity and accuracy through quality control techniques
- Transform datasets between coordinate systems and/or datum
- Extract building model information from 3D point cloud and create CD CAD models
- Digitize construction related features from aerial imagery and perform geo-referencing of aerial imagery data
What Is the Job Demand for Geospatial Analysts?
Job demand for this type of role is expected to grow at a rate of 29% in the decade between 2014 and 2024. This is one of the highest job growth areas at present, mostly because GIS has become so cheap to implement in recent that the essential service it provides is now a cost effective solution for many industries, especially in construction, transport and regional planning, conservation and protection, heritage research and the environmental sciences and mapping. Mobile technology is responsible for this in part and its wide use is expected to fuel further demand and growth. However, it remains a small industry so the actual number of openings will remain small.
What Are the Education Requirements to Become a Geospatial Analyst?
As this is a practical science that bridges IT and environment high school students will require good grades in these areas. They will need to demonstrate information technology and science aptitude and in geography and environmental studies. Good grades in math will be a great asset. This will ensure good grounding for a relevant degree course.
As far as your degree is concerned, you have many options available to you - geography, geoscience, cartography, surveying, geomatics, anthropology, archaeology and planning. Whichever path you choose will largely determine which sector you work in but you will have transferable skills that mean moving is possible. Whichever you choose, it is essential that you study the methods associated with this role - that means GIS, surveying and anything where you may be able to study maps and/or aerial photographs. Other relevant degrees include information science, forestry and engineering.

Although master's degrees will not be essential for the practical work associated with this role, it may be useful for those seeking high-level decision-making or project management roles and those wishing to engage in primary research. A doctorate is unnecessary unless the student wishes to teach some of the practical skills required for the job (as a GIS professor for example).
