Texas Purpose of the Procedure Flood insurance studies search for geospatial data during pre-scoping and scoping tasks. If needed data are not available, studies might fund the collection of new data and would like to know about other organizations that might share in these costs. Detailed information about the role geospatial data coordination plays in studies is in the Geospatial Data Coordination Implementation Guide, which is available at , and in Scoping Guidelines: Pre-scoping and the Scoping Meeting, which is available through the Regional Management Center (RMC). Resources developed through FEMA’s geospatial data coordination activities provide information about data and contacts for organizations that have geospatial data that cover large areas (like states) in which many studies are interested. Studies can avoid wasting time with dead-end searches and cold calls by starting with these proven sources of information. One resource is this Geospatial Data Coordination Procedure. It outlines sources of geospatial data and contact information, preferences for base map data and state geospatial participation in studies, and other useful information for the State. If you have questions about this procedure or other geospatial data coordination resources, contact the geospatial data coordination lead in your Regional Management Center: Roberto E.

Geospatial Data Coverage Find below information about and links to statewide (and Federal agencies’ national) geospatial datasets. The list is provided to save time during pre-scoping and scoping activities when building a list of candidate geospatial datasets available for the study; it is not a prescription of datasets that must be used in a flood insurance study.

Finding and Accessing Other Existing Geospatial Data Find below information about and links to ways of searching for additional geospatial data available for the State. These capabilities can be useful for finding geospatial data other than the statewide and Federal data listed above, including those of special governments, counties and parishes, municipalities, tribes, universities, and other organizations.

To access the NDOP system, go to the NDOP web site at and follow the link “Project Tracking.” For the NDEP system, go to the NDEP web site at and follow the link “Project Tracking.” TED Query Tool This tool provides access to information about Federal, state, and local government agency and private sector data holdings gathered by the Census Bureau. It is available through the geospatial data coordination lead at the Regional Management Center. Geospatial One-Stop Geospatial One-Stop, available at , provides access to geospatial data from many sources. Two parts of the site that should be investigated are the “data categories” for existing data and the “marketplace” for data that are planned or in-work and for potential partners for new data collection activities. Working with People Useful State and Federal Contacts The main contacts for the State’s geospatial activities and Federal agencies’ representatives in State are available on the Mapping Information Platform web site at: . Involving the State’s Geospatial Coordinator in Flood Studies The coordinator participated in the development of this Procedure. The State has a strong Flood Plain Managers Association that coordinates on many issues concerning FEMA. Personnel from the TNRIS StratMap program actively coordinate data collection and identification efforts with FEMA State Coordination Process for Building Geospatial Partnerships The State has a GIS Coordination Council – Texas Geographic Information Council (TGIC) http://www.dir.state.tx.us/tgic/ Finding Local Geospatial Contacts Local contacts, including those from special government districts (for example, a regional planning commission); counties, parishes, or equivalent governments; tribes, municipal governments; and other organizations (for example, local universities) also have geospatial data that can help a flood insurance study. Contact information is available from the FEMA archive and web searches at government link portals such as . The state maintains a statewide GIS contacts list in the following formats: a. Spreadsheet b. Word Document The information is available from the State GIS Coordinator listed at the beginning of this Procedure. The levels of government in the list are: a. State b. Regional The State has strong regional planning commissions/councils of government. Provide Feedback on This Procedure When you find information in this Procedure or in other FEMA or State resources that are outdated, please tell the geospatial data coordination lead in the Regional Management Center what was wrong and the correct information (if you know it). Use the contact information for the lead listed in the section Purpose of the Procedure. The lead will use your feedback to update this Procedure.
