This dataset provides spatial data and visualizations for flood inundation scenarios generated from the H&H model and their impact on road networks in Harris County, Texas. It includes inundation depth maps, road inundation data, and estimated road damage assessments across 17 flood scenarios. The dataset is structured as GeoJSON files and accompanying visual figures. This dataset is part of the research conducted under the Coastal Research and Education Actions for Transportation Equity (CREATE) project, funded by the Tier 1 University Transportation Center (UTC) and supported by the U.S. Department of Transportation (DOT).

The total size of the zip file is 68.8 MB. Desktop Services Store files, or DS_STORE Files, are Mac OS files that stores desktop attributes such as icons and colors. They are only used by Mac OSs and don't require additional software (for more information on .ds_store files and software, please visit https://www.file-extensions.org/ds_store-file-extension). The .geojson format is an open geospatial format used to encode a variety of geographic data structures. The file type can be opened and use by many GIS programs, such as ArcGIS and QGIS (for more information on .geojson files and software, please visit https://www.file-extensions.org/geojson-file-extension). The following file types are standard for GIS mapping software: AUX, CSF, DBF, PRJ, SBN, SBX, SGML, SHP, LOCK, SHX, CSF, CPG, LYR, MXD, FDBINDEXES, GDBTABLE, GDBTABLX, ATX, SPX. Because the files pertain to map layers and images, they are best viewed using the software that the team used or with any open source 2D and 3D mapping software. The .dbf file extension is traditionally used for database file by many database applications. The original program, which used the DBF file extension for its database, was dBAse. A major legacy of dBase is its dbf file format, which has been adopted in a number of other applications. For example, the shapefile format developed by ESRI for spatial data in a geographic information system uses .dbf files to store feature attribute data (for more information on .dbf files and software, please visit https://www.file-extensions.org/dbf-file-extension). The .prj file extension is traditionally used for files that contain projects. Projects contain settings, positions of saved windows, development notes and other raw data that won’t be present in the final file (for more information on .prj files and software, please visit https://www.file-extensions.org/prj-file-extension). The .shp file extension is used for ESRI Shape format, a popular geospatial vector data format for geographic information systems software. A shapefile stores non-topological geometry and attribute information for the spatial features in a data set. A shapefile consists of a set of 3 mandatory files, along with several optional files. Each file in the set shares the shapefile name with a different extension. The main file .shp stores the geometry and must always have an index file .shx. A dBASE file .dbf stores all the attributes of the shapes in the main file. Additionally, a projection file .prj stores the projection information (for more information on .shp files and software, please visit https://www.file-extensions.org/shp-file-extension). A .shx file contains compiled shape data (building blocks, fonts) in form of the machine language compiled version of an .shp file. The file type is associated with AutoCAD, a CAD development platform, developed and sold by Autodesk, Inc (for more information on .shx files and software, please visit https://www.file-extensions.org/shx-file-extension). The .cpg file extension is associated with the ArcGIS, a geographic information system for Microsoft Windows operating system, developed by Esri. The .cpg file stores codepage for identifying a character set (for more information on .cpg files and software, please visit https://www.file-extensions.org/cpg-file-extension-arcgis-codepage). The file extension .png is commonly used for images in Portable Network Graphics file format. PNG is a bitmap graphics format similar to GIF, that uses image compression mainly for web purposes (for more information on .png files and software, please visit https://www.file-extensions.org/png-file-extension). The .txt file type is a common text file, which can be opened with a basic text editor. The most common software used to open .txt files are Microsoft Windows Notepad, Sublime Text, Atom, and TextEdit (for more information on .txt files and software, please visit https://www.file-extensions.org/txt-file-extension).
