The Counties of British Columbia contains areas of land within the Province of British Columbia representing legally defined administrative areas described in the County Boundary Act. The purpose of this division is for the administration of justice. The counties were delineated using provincial base mapping features, following the metes and bounds descriptions in the Letters Patent. A polygon dataset that includes all of the administrative areas currently in the Administrative Boundaries Management System (ABMS) is available here. A complimentary point dataset that defines the administrative areas is also available here. The Legal document which divides the province of British Columbia into counties is available here. Other individual datasets are available from the following records: https://catalogue.data.gov.bc.ca/dataset/province-of-british-columbia-legally-defined-administrative-areas-of-bc https://catalogue.data.gov.bc.ca/dataset/municipalities-legally-defined-administrative-areas-of-bc https://catalogue.data.gov.bc.ca/dataset/regional-districts-legally-defined-administrative-areas-of-bc https://catalogue.data.gov.bc.ca/dataset/electoral-areas-legally-defined-administrative-areas-of-bc https://catalogue.data.gov.bc.ca/dataset/islands-trust-legally-defined-administrative-areas-of-bc https://catalogue.data.gov.bc.ca/dataset/local-trust-areas-legally-defined-administrative-areas-of-bc https://catalogue.data.gov.bc.ca/dataset/sh-sh-lh-nation-legally-defined-administrative-areas-of-bc

The data release for the geologic and structure maps of the Kalispell 1 x 2 degrees quadrangle, Montana, and Alberta and British Columbia, is a Geologic Map Schema (GeMS)-compliant version that updates the GIS files for the geologic map published in U.S. Geological Survey (USGS) Miscellaneous Investigations Series Map I-2267 (Harrison and others, 2000). The updated digital data present the attribute tables and geospatial features (lines and polygons) in the format that meets GeMS requirements. This data release presents the geologic map as shown on the plates and captured in geospatial data for the published map. Minor errors, such as mistakes in line decoration or differences between the digital data and the map image, are corrected in this version. The database represents the geology for the 16,436 square kilometer, geologically complex Kalispell 1 x 2 degrees Quadrangle, at a publication scale of 1:250,000. The map covers primarily Flathead and Lincoln Counties, but also includes minor parts of Glacier, Lake, and Sanders Counties. These GIS data supersede those in the interpretive report: Harrison, J.E., Cressman, E.R., Whipple, J.W., Kayser, H.Z., Derkey, P.D., and EROS Data Center, 2000, Geologic and structure maps of the Kalispell 1:250,000 quadrangle, Montana, and Alberta and British Columbia: a digital database: U.S. Geological Survey Miscellaneous Investigations Series Map I-2267, version 1.0, 23 p., scale 1:250,000, https://pubs.usgs.gov/imap/i2267/.

Outlines the boundaries of the Baltimore County Historic Districts. The agreement by the owners of 75 percent of the property within a proposed district’s boundary is required to form a local historic district. Any exterior modification or addition to a structure in a district, or any excavation building, or demolition permit, is subject to approval by the Landmarks Preservation Commission.

Feature class contains all contour lines for Baltimore County. Contours are captured in 2 foot intervals. Contours were created from LiDAR captured to meet or exceed the FEMA QL 2 specification. LiDAR was captured in April of 2014.

Following the 2013 flood, the Colorado Water Conservation Board (CWCB) initiated a program to re-map the predicted 1% chance regulatory floodplain (100-year flood zone) of the most affected waterways. The program was named the "Colorado Hazard Mapping Program" or "CHAMP." This has been adopted by the Boulder County Commissioners, and will be used for regulatory decisions by the county. Not necessarily used for determining flood insurance.

Baltimore County's Urban Rural Demarcation Line (URDL) has divided the county into "urban" and "rural" areas since established by the Planning Board in 1967. Developed primarily as a growth management tool, it has influenced zoning, land-use, and infrustructure decisions, and was the baseline for the Baltimore County part of Maryland's Priority Funding Area. However, this boundary (digitized at a scale of 1:24,000 where 1" represents 2,000') was became obsolete as the county's GIS data increased in resolution (to 1:2,400 where 1" represents 200'). Until recently, determining a property's status as either urban or rural was of a highly interpretative nature. A new URDL was developed to more accurately match the 1:2,400 data (parcel, street centerline, zoning, etc). This version was reviewed and modified in a series of meetings with several interested county agencies. The new URDL removes much of the old one's ambiguity while keeping its original intent. The new URDL was reviewed, modified, and subsequently approved by the Planning Board on June 19, 2003. Minor revisions were effected 9/2/04, 10/21/04, 9/4/07, 5/21/09, 10/1/09 and 11/15/12. The URDL_poly feature class is one part of the URDL feature dataset.

1:24,000-scale, full-color geologic map of the Striped Hills 7.5' quadrangle, Nye County, Nevada, with 2 cross sections and description of 40 units. Detailed geologic mapping by K.A. Sargent, Edward J. McKay, and B.C. Burchfiel in 1970. The GIS work was in support of the U.S. Geological Survey COGEOMAP program. The Geodatabase specifies feature datasets and feature classes, together with feature attributes, subtypes and domains, suitable for a variety of geologic maps. In addition to basic geology (lithology, contacts and faults, etc.), the maps may include metamorphic overprints, cross sections, and explanatory legend-graphics such as correlation charts, used to supplement columnar legends. Previous work includes the Geologic map of the Skull Mountain quadrangle (Poole, Elston, and Carr, 1965); and the Geologic map of the Skull Mountain quadrangle (Ekren and Sargent, 1965).

This feature class represents the petitioned sewer master plan areas that have been introduced in previous years through cycle amendments within Baltimore County. Unlike the SHisMasterPlan feature class, this feature class does not distinguish between different cycle amendment petitions and only reflects the most current sewer master plan designation.The sewer master plan geodatabase includes a feature data set (sewerMasterPlan) containing three feature classes: SCurMasterPlan, sewerCombined and SHisMasterPlan. The feature classes participate in a topology (tsewerMasterPlan). The SCurMasterPlan feature class represents the petitions for the current cycle. The sewerCombined represents the current master plan designation within the county. The SHisMasterPlan contains all of the petitions areas from all cycles. The geodatabase includes relationship classes that associate related table containing information on assessments, councilmanic districts, election districts, lineage (feature level metadata), plan map, recommendations and zoning designations.

The MetroDistrict feature class contains the current land area included in the metropolitan district in Baltimore County. The metropolitan district is a land planning area determines the status of whether or not a property is eligible for public water and sewer services.The metropolitan district geodatabase includes the MetroDistrict, MetroDistrictLine, MetroDistrictPoly, MetroDistrictMargin feature classes and BCMDLineage table.

The LOMA feature class contains features for each address for which a LOMA has been issued by the Federal Emergency Management Agency (FEMA). A LOMA can affect flood zone determination without a map change. The feature class was created by interpreting the information contained on each LOMA and mapping the location(s) for each of the addresses cited in the document. A PDF of the LOMA document was associated to the feature as an attachment. For addresses having more than one LOMA, only a single feature was created and additional attachments were associated to the feature. This feature class contains “historical” LOMA location/documents not revalidated by FEMA.

This database consists of a series of maps showing the estimated inundation of Hawaii shorelines caused by hypothetical category 1, 2, 3, and 4 storm surges. Individual maps show inundation across mile-long sections of Hawaii state routes on the islands of Hawaii, Maui, Molokai, Oahu and Kauai previously identified for their vulnerability to the effects of climate change as part of the Statewide Coastal Highways Project Report.

Mileposts are identified by Brandes et al. (2019). State of Hawaii Department of Transportation (HDOT) state routes and Oahu street centerline datasets are acquired from HDOT (2017) and HOLIS, C&CH (2017). Storm surge maximum of maximum (MOM) inundation extents are determined by the NOAA National Hurricane Center Storm Surge Unit using the Sea, Lake and Overland Surges from Hurricanes (SLOSH) model and are reported in Zachry et al. (2015).
