What We Do

Siglo Group uses the power of geographic information to help our clients integrate land use with natural systems.  Understanding a site’s ecological characteristics and history enables clients to work with and take full advantage of existing natural systems.  This helps prevent issues like erosion and flooding, while enhancing natural benefits such as diverse wildlife habitat, beautiful views, soil stabilization, and clean water and air.

Siglo has worked on sites ranging from small city parks and private ranches to large, multi-county regions.  We specialize in conservation planning, cartography, natural area management, regional analysis, and land management plans.  Using maps, reports, presentations, and dynamic web tools, we support our clients with decision-making and planning, as well as education and outreach initiatives.  We pride ourselves on producing visually compelling and informative products about a range of complex issues within the timeline and budget needs of a particular project.


The integration of conservation into land planning and design was a driving force in the creation of our firm.  We are always happy to work with land trusts, municipalities, developers, and other clients to further the smart use of natural resources in efficient and cost effective ways.

We provide both planning and field assessment services, working with areas ranging from a single parcel to an entire state or region.  We have worked with land trusts and municipalities to determine conservation priorities on over 30 million acres, and have conducted site assessments on over 50,000 acres of land.   We have extensive experience creating Baseline Documentation Reports to accompany conservation easements.

Regional Analysis

New geographic technologies allow us to analyze large areas, giving unprecedented insights into land use trends and natural systems.  Before, geographic data on such a large scale either did not exist or was too cumbersome to analyze.  GIS analysis now helps drive better decision-making, smarter use of resources, and a greater rate of return on investment.

Our team has over 20 years of combined experience working with GIS.  We have a robust geographic data collection spanning Texas and much of the Americas from public and private sources.  We have provided clients with maps displaying regional analyses of: investment opportunities, development, land use patterns, environmental impacts, conservation priorities, transportation, land values, municipal relations, regulatory authority, and utility and emergency services.  We also compile geographic data for clients, delivering final datasets in a user-friendly, updateable format.

Regional analysis is also an important part of public planning initiatives, and we have experience presenting findings at public meetings, as well as using interactive planning tools to foster public discussion.  We can also conduct stakeholder interviews and public surveys to get a fuller understanding of the community’s interests and concerns.

Site Assessment

Understanding the impact of different land uses is at the heart of our work.  Through geographic analysis and field assessment, we provide information to inform clients’ decisions regarding development feasibility, conservation value, land management planning, environmental protection, and regulatory feasibility.

Requests for land evaluations come from private landowners, land trusts and other nonprofits, municipalities, developers, law firms, planning firms, engineers, architects, and landscape architects.  Depending on the site and the client’s needs, these assessments can outline regulatory and development constraints as well as provide an inventory of site characteristics.  They can include slope analysis, a photographic inventory, GPS documentation, infrastructure inventory, density analysis, water quality buffer delineation, land use analysis, set-back buffers, critical environmental feature documentation, endangered species occurrences, plant communities, wildlife and bird surveys, soil analysis and geologic analysis.

For properties with public use such as greenbelts, parks and museum grounds, Siglo also looks at the visitor experience, making recommendations for the wayfinding system and site interpretation, refining trail systems, and tailoring land management recommendations to minimize disruption for visitors and enhance aesthetic appeal.  We also have experience conducting visitor surveys to help inform our analysis and to aid the client’s future planning.

Natural Area Management

Building upon a detailed site assessment, Siglo Group makes management recommendations for natural areas combining known best practices, site-specific considerations, and ecological restoration principles within an adaptive management framework.  The goals for projects include enhanced plant communities and wildlife habitat, improved ecological function, greater resiliency, enhanced user experiences, and greater opportunities for stewardship.  Principles are broken down into implementable, prioritized tasks based on available resources over time such as:  soil care, invasive species management, erosion control, planting, and seeding.  Land management is integrated into the user experience through visitor surveys, trail management recommendations, defining access to amenities, wayfinding systems, interpretation, and overall aesthetic enhancement.

Web Geography

The use of geographic content on the web is expanding rapidly.  Siglo Group leverages knowledge of geographic data and web design to create windows of geographic information customized to the client’s needs.

We offer Google Maps web applications, animations, image viewers, and presentations to convey information over the web or share with a limited group.  Examples of these projects include:

  • The most comprehensive geographic web viewer for the Hill Country, created through our work with Hill Country Alliance.
  • Fly-through animations that have helped both Hill Country Alliance and Clear View Alliance explain land use issues.
  • Over 100 maps showing tours across the globe for Victor Emanuel Nature Tours.

This is an exciting branch of our work and we look forward to helping more clients harness the incredible amount of geographic information that is available to use and share on the web.


Siglo Group combines the traditions of high quality cartography with modern geographic information technologies.  Our mapping products are used for decision-making, as exhibits at public meetings, and by private landowners to better understand and appreciate their land.  Our maps have also been used on websites and in brochures, presentations, and publications.  The high graphic quality has allowed them to become central to land use, conservation, and development projects.

Our extensive database, lean business model, and technical skills make it feasible for us to deliver high quality visual material to our clients with information from just about every corner of the globe.
