The technical and organizational complexity of GIS for Next Generation 9-1-1 is just one of the many considerations for decision makers when determining an NG9-1-1 solution. Whether the deployment will be PSAP-by-PSAP, County-by-County, or as a regional or statewide implementation, one common goal is the seamless connectivity of data to support the 9-1-1 caller. To prepare for this level of interoperability, 9-1-1 and GIS decision makers have the added challenge of how to best meet NG9-1-1 needs and requirements while still recognizing the autonomy of the many data providers that have the added responsibility of supporting the business needs of their individual communities.

The complexity of a GIS ecosystem can grow exponentially when one considers the scope of the various deployment “patterns” that are possible to meet the data validation, aggregation, and provisioning requirements for multi-jurisdictional entities. It is quite common for adjoining jurisdictions to have completely different GIS data that has widely varying data quality and is updated on similar varying update cycles. The management challenge grows as each adjoining jurisdiction is added to the larger collaboration effort.

Scalable solutions that allow for iterative validation and aggregation from multiple sources into a single database help to ensure the capability to support the interoperable needs of NG9-1-1. The ability to:

Power of Partnerships: Standardizing and Streamlining Preliminary Damage Assessments

In 2019, there were 100 major presidentially declared disasters in the U.S. providing recovery assistance to 39 affected states and territories. In order to obtain a presidential declaration, a governor or tribal chief must submit a request to their Federal Emergency Management Agency (FEMA) regional office for assistance. This request includes preliminary damage assessment (PDA) information to document the extent of the disaster and its impact on individuals and public facilities. PDA information is used to show that the disaster is of such severity and magnitude that supplemental federal assistance is necessary for response and recovery efforts. For severe or catastrophic events, a governor or tribal chief may submit a declaration request prior to performing a PDA.

At Dewberry, we understand that dealing with the aftermath of a disaster is a stressful and trying time. Documenting damages can take time and resources that are better spent focusing on response and recovery efforts. Disasters are increasing in frequency and severity, therefore a streamlined approach to documenting damages makes the process of submitting declaration requests faster—facilitating an expedited recovery process. In partnership with ArdentMC, Dewberry supports FEMA, states, territories, and local agencies to help better quantify and quickly assess damage in an effort to expedite needed aid to impacted communities. We are now helping to facilitate and simplify the PDA process in an effort to decrease assistance timelines. Under this contract work with FEMA, the team is providing subject matter and technical expertise to help standardize collection of incident reported damage assessments in impacted areas using newly designed Esri Survey123 templates. These templates use GIS technology to electronically collect, submit, and validate damage assessment in a standardized and sharable way. The platform being used to manage the data collection is hosted in an Amazon Web Services (AWS) GovCloud region and is accredited by the Department of Homeland Security (DHS). Utilizing ArdentMC’s AWS competency in public safety and disaster response, coupled with Dewberry’s gold partnership with Esri, the PDA team has created a highly scalable collection platform for FEMA’s damage assessment mission.

NSGIC Annual Conference: Five Things on Our Minds

It’s been 55 years since Bob Dylan penned the times they are a-changin’, but that sentiment is truer than ever today in the world of GIS. Although we could make a lengthy list of things a-changin’, we’ve picked these top five, which we feel are particularly relevant to state GIS leaders. We look forward to conversations with you in Snowbird!

  1. Strategic planning 2.0 -- Many states haven’t done a full-on strategic plan since the FGDC Cooperative Agreement Program (CAP) grants from a decade ago. There’s been a whole lot of change since then, with new players, new paradigms for data access, new technology options, new political realities, and more. In our view, we need a change, a v2.0 approach to strategic thinking about the roles and goals of geospatial and its societal impact. A strategic plan sets the course for both vision and activities in a state GIS office, so this piece is very, very important.
  1. Geospatial Data Act -- It’s finally federal law, which means that it’s finally time for the US (and us!) to get serious about building and supporting a shared set of national geospatial capabilities. States will have a key role as the middle layer between national and local level participants in this endeavor. There are also opportunities to connect some national geospatial data silos, such as Next-Generation 9-1-1 and the National Address Database, which we need to move from idea to reality. This ties in nicely with v2.0 strategic planning, which is a formal responsibility of the Federal Geographic Data Committee (FGDC) under the new law. Ideally, the FGDC would again step up and provide support for the level of multilateral, nested strategic planning needed to engage the broad and diverse geospatial stakeholder community.
  1. New urgency on environmental problems -- We’re facing ever more urgent problems with more potent hurricanes and storms, greater wildfire threats, increased flooding potential, accelerating human consumption of natural resources, and many other issues. All of these need geospatial analytics to understand, and even predict the risks we now face and to develop solutions. If you are a parent (and even if you are not), these environmental issues should concern you and spur you to engage as truth-tellers with GIS.
  1. The shifting sands of geospatial data sources -- It wasn’t that long ago that government was the primary source of most GIS data, but that is becoming less and less true. We are seeing huge geospatial data investments from global internet companies, the auto industry, new imagery providers, and an explosion of data coming from sensors and “things” everywhere. This shift requires a rethinking and repositioning of the role of state GIS offices as the [providers/aggregators/curators/distributors] of geospatial data. See also, strategic planning, v2.0, above.
  1. Addresses, addresses, addresses -- It has become increasingly clear that address data containing accurate lat/long coordinates attached to every street address record is so fundamental to so many important uses, that we need to redouble our effort to get this done right, and done in a way that leverages the support resources and capabilities of many separate constituencies who will otherwise continue to work on address data separately. Oddly enough, this ties in with v2 strategic planning.

You might have a different list of top five issues, and we’d love to hear them. We look forward to having some great conversations with you at the NSGIC conference. For us, it’s the best event of the year to talk with the top geospatial thinkers and movers. We can share our observations with you that come from the rich variety of projects we’re involved in across the country. And we love to hear your perspective on what you see a-changin’ from the driver's seat as state GIS leaders.

South Central TX LiDAR Project

Enhanced Hydrology in Texas LiDAR by Merrick-Surdex JV Critical to Risk Mapping

In 2017 the USGS selected the Merrick-Surdex Joint Venture to collect and process LiDAR data of approximately 17,950 square miles in Southwest Texas. One of the funding partners to the project, FEMA, required new elevation data in order to reclassify older hydrographic features to improve flood map accuracy. The data will be used to assist in risk management of potential flooding areas, due to significant shifts in precipitation over the past decade.

The State of Texas has experienced a nearly decade-long drought; in February 2018, nearly 90% of the state was under a drought warning. Within one year, these conditions shifted dramatically – in 2018, rains had been so persistent and heavy that by October less than 5% of the state was under a drought warning. This sudden increase in such a large volume of water has created a scenario with a notable risk of overflowing and flooding of once-dry riverbeds. The state consequently switched from a drought status to a situation of potential widespread flooding, with all the subsequent possibility of damage. FEMA and Texas Water Development Board (TWDB) anticipating the effects of such a situation, initiated a project with the USGS to obtain data to manage this new condition.

The Joint Venture’s effort towards the collection of hydrographic features was designed to exceed the USGS project specifications and to ensure map accuracy so that hydrological events could be monitored with confidence. Production staff invested a higher than normal amount of time and effort to identify stream banks that have been undefined by water for years due to drought. According to version 1.3 of the USGS LiDAR Base Specification, the minimum width for the collection of inland streams and rivers is 100 feet however due to the low water levels there are multiple instances where these features were as narrow as 10-15 feet and ordinarily would not have been collected. In several cases, widths varied considerably along the same stream, and had the only the portions of rivers/streams greater than 100 feet been collected, it would have resulted in disconnected networks of drainage. Additionally, several lakes/ponds would have been omitted for not meeting the minimum two-acre size criteria. These conflicts of elevation in the hydro-flattened Digital Elevation Models (DEMs) would have limited the data usefulness to all agencies. The process chosen will ensure map accuracy and hydrological events could be monitored with confidence.
