Vector polygon map data of city limits from Houston, Texas containing 731 features.

City limits GIS (Geographic Information System) data provides valuable information about the boundaries of a city, which is crucial for various planning and decision-making processes. Urban planners and government officials use this data to understand the extent of their jurisdiction and to make informed decisions regarding zoning, land use, and infrastructure development within the city limits.

By overlaying city limits GIS data with other layers such as population density, land parcels, and environmental features, planners can analyze spatial patterns and identify areas for growth, conservation, or redevelopment. This data also aids in emergency management by defining the areas of responsibility for different emergency services, helping to streamline response efforts during crises..

This city limits data is available for viewing and sharing as a map in a Koordinates map viewer. This data is also available for export to DWG for CAD, PDF, KML, CSV, and GIS data formats, including Shapefile, MapInfo, and Geodatabase.

This digital elevation model (DEM) is a part of a series of DEMs produced for the National Oceanic and Atmospheric Administration Coastal Services Center's Sea Level Rise and Coastal Flooding Impacts Viewer. The DEM includes the 'best available' lidar data known to exist at the time of DEM creation that meets project specifications for those counties within the boundary of the Houston/Galveston TX Weather Forecast Office (WFO), as defined by the NOAA National Weather Service. The counties within this boundary are: Jackson, Matagorda, Brazoria (portion), Harris (portion), Galveston, and Chambers. For all the counties listed, except for Harris, the DEM is derived from LiDAR data sets collected for the Texas Water Development Board (TWDB) in 2006 with a point density of 1.4 m GSD. LiDAR data for Harris County was collected in October 2001 by the Harris County Flood Control District Tropical Storm Allison Recovery Project (TSARP) with a point density of 2.0 m GSD. Hydrographic breaklines used in the creation of the DEM were delineated using LiDAR intensity imagery generated from the data sets. The DEM is hydro flattened such that water elevations are less than or equal to 0 meters.The DEM is referenced vertically to the North American Vertical Datum of 1988 (NAVD88) with vertical units of meters and horizontally to the North American Datum of 1983 (NAD83). The resolution of the DEM is approximately 10 meters.

Dates of Images:Pre-Event: April 2024Post-Event: 5/18/2024, 5/19/2024, 5/20/2024Date of Next Image:UnknownSummary:The Black Marble High-Definition (BMHD) images were created by the NASA Black Marble Science team, with directed funding the NASA-Google Partnership program. The images map the impact of extreme heat in Houston, Texas on electric grids. The baseline image is from April 2024, a cloud-free, moon-free composite, and the “after" image is from May 18, 2024 - May 20, 2024. There is a layer to display where clouds are present in the "after" images. This comparison between the images is meant as a visual assessment of outage impacts from the extreme heat to aid various partners who are working to deliver emergency aids to local communities. Power outage maps like these help disaster response efforts in the short-term as well as long-term monitoring during the crucial stages of disaster recovery.From the BMHD data, zonal statistics were collated with FEMA's National Risk Index (NRI) Social Vulnerability score to identify areas where vulnerable populations were affected by power outages. Higher (red) census tract areas indicate a higher amount of power lost relative to the second date listed. For example, a red polygon in the Baseline (April) - May 18th layer indicates that specific area lost disproportionately more power and is in an area with high social vulnerability risk when comparing the normal power available (baseline) to when the disaster occurred.Suggested Use:NOTE: Black Marble HD images are downscaled from NASA’s Black Marble nighttime lights product (VNP46), and as such are a “modelled” or “best guess” estimate of how lights are distributed at a 30m resolution. These images should be used for visualization purposes, not for quantitative analysis.The image is in a yellow-red color scale. Red indicates more severe impacts. Grey polygons are acquired from cloud cover and represent areas where no data was available on a given day.Satellite/Sensor:The primary data source, NASA’s Black Marble nighttime lights product suite (VNP46), utilized to generate this product is derived from the Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) onboard the Suomi National Polar-orbiting Platform (SNPP) along with high resolution base layers - Landsat derived normalized index products (NDVI and NDWI) and OpenStreetMap (OSM) derived road layerResolution:Scaled resolution of 30 metersCredits:NASA Black Marble Science teamFEMA National Risk Index (NRI) TeamPlease cite the following two references when using this data:Román MO, Stokes EC, Shrestha R, Wang Z, Schultz L, Carlo EA, Sun Q, Bell J, Molthan A, Kalb V, Ji C.

Hurricane Harvey made landfall near Rockport, Texas on August 25 as a category 4 hurricane with wind gusts exceeding 150 miles per hour. As Harvey moved inland the forward motion of the storm slowed down and produced tremendous rainfall amounts to southeastern Texas and southwestern Louisiana. Historic flooding occurred in Texas and Louisiana as a result of the widespread, heavy rainfall over an 8-day period in Louisiana in August and September 2017. Following the storm event, U.S. Geological Survey (USGS) hydrographers recovered and documented 2,123 high-water marks in Texas, noting location and height of the water above land surface. Many of these high-water marks were used to create flood-inundation maps for selected communities of Texas that experienced flooding in August and September, 2017. The mapped area boundary, flood inundation extents, and depth rasters were created to provide an estimated extent of flood inundation along the West Fork San Jacinto River and East Fork San Jacinto River within counties of Grimes and Walker, Texas. The mapped area of the San Jacinto Basin and tributaries were separated into two sections due to the availability and location of high-water marks for the West Fork San Jacinto River and East Fork San Jacinto River. The inundation map of the West Fork San Jacinto River is a 36-mi reach of the main stem of San Jacinto River near Conroe, Tex. and includes Cypress Creek (53-mi reach), Little Cypress Creek (21-mi reach), Willow Creek (6-mi reach), Spring Creek (68-mi reach), Walnut Creek (15-mi reach), Panther Branch (11-mi reach), Lake Creek (7-mi reach), and Crystal Creek (2-mi reach). The inundation map of the East Fork San Jacinto River is a 65-mi reach of the main stem of the San Jacinto River near Coldspring, Tex. and includes White Oak Creek (9-mi reach), Caney Creek (31-mi reach), Peach Creek (19-mi reach), Winters Bayou (33-mi reach), and Luce Bayou (9-mile reach). The 18-mi reach of the San Jacinto River from the confluence of the west and east forks to the Lake Houston Dam near Shelton, Tex. is also included in the inundation map. These geospatial data include the following items: 1. bnd_west and bnd_east; shapefiles containing the polygon showing the mapped area boundary for the West Fork and East Fork San Jacinto River flood maps, 2. hwm_west and hwm_east; shapefiles containing high-water mark points used for inundation maps, 3. polygon_west and polygon_east; shapefiles containing mapped extent of flood inundation for the West Fork and East Fork mapped sections of the San Jacinto River, derived from the water-surface elevation surveyed at high-water marks, and 4. depth_west and depth_east; raster files for the flood depths derived from the water-surface elevation surveyed at high-water marks. The upstream and downstream mapped area extent is limited to the upstream-most and downstream-most high-water mark locations. In areas of uncertainty of flood extent, the mapped area boundary is lined up with the flood inundation polygon extent. The mapped area boundary polygon was used to extract the final flood inundation polygon and depth raster from the water-surface elevation raster file. Depth raster files were created using the "Topo to Raster" tool in ArcMap (ESRI, 2012). The HWM elevation data from the USGS Short-tern Network (STN) was used to create the flood water-surface raster file (U.S. Geological Survey [USGS], 2018, Short-Term Network Data Portal: USGS flood information web page, accessed February 13, 2018, at https://water.usgs.gov/floods/FEV.). The water-surface raster was the basis for the creation of the final flood inundation polygon and depth layer to support the development of flood inundation map for the Federal Emergency Management Agency's (FEMA) response and recovery operations.
