Several layers were examined as part of the highway improvement needs analysis conducted for the 2017 State Transportation plan.Existing and candidate park and ride lots in the state of Iowa, represented as linear features. Features were created using a 2-mile buffer around each lot to represent primary routes that could potentially be viable (re)locations for park and ride lots. 2-miles was selected for the buffer area based on the FHWA report "Safety Assessment of Interchange Spacing on Urban Freeways" publication number FHWA-HRT-07-031. https://www.fhwa.dot.gov/publications/research/safety/07031/The Iowa Department of Transportation’s park and ride system consists of state-owned park and ride lots. Many of these lots were developed during the 1980s, primarily in response to a growing demand that resulted from an increase in fuel prices. In most cases, lot development was truly the result of grassroots efforts, with Iowa DOT’s district offices often responding to specific public requests for park and ride facilities. In 2014, The Iowa Park and Ride System Plan was developed. This plan includes an update of the existing inventory, an identification of additional locations suitable for park and ride facilities, and strategies for implementation .The plan will be used by the Iowa DOT to plan, evaluate, and develop a formal state-owned-and-operated system of park and ride facilities. The primary objective of the plan is to provide a location-specific, priority-based park and ride system that allows for coordinated planning and implementation of park and ride facilities. As a part of the plan this database was created to geographically reference both existing state-owned park and ride facilities and ideal candidates for future expansion of the system. This database will also be used in coordination with the statewide rideshare program, so it will also include other existing park and ride facilities not owned by the state or identified in the plan. Ultimately this inventory has two main purposes that can be described generally as internal and external. Internally, the database will be used to keep track of state-owned inventory and identify opportunities for the expansion of the state-owned and operated park and ride system. Externally, the database will be expanded to include a wide array of park and ride facilities across the state of Iowa that can be disseminated to the public via the Iowa DOT website and coordinated with the rideshare program.

TwitterAirport Reference Point Buffers are six-mile buffer rings around each of the public use airport reference points (ARP) in Wisconsin. Buffer rings for each public airport facility type have been developed by WisDOT and are based on requirements outlined in Section 20-55-55 of the Wisconsin Department of Transportation's Facilities Development Manual (FDM). The FAA recommends a distance of 5 miles between the closest point of the airport’s aircraft operations area (AOA) and any hazardous wildlife attractant. The Bureau of Aeronautics has created a six-mile buffer around the Airport Reference Point (ARP) due to the dynamic nature of aircraft operations areas. These areas account for varying distances from the edge of the AOA to the ARP. This data is intended to provide general guidance and airport information for highway construction projects in and around Wisconsin airports, specifically to make contractors and consultants aware of these areas.An airport reference point (ARP) is the center point of an airport, located at the geometric center of all the usable runways. FAA's ADIP site contains the most current airport and aeronautical data available. Airport Reference Points are a separate point feature class.

TwitterThis data represents the Human Disturbances Dataset for the North Slave Region, South Slave Region, Sahtu Administrative Region, and Inuvik Administrative Region (and/or Inuvialuit Settlement Region)using information from the Mackenzie Valley Land and Water Board, Wek'eezhii Land and Water Board, Gwich'in Land and Water Board, Sahtu Land and Water Board, Inuvialuit Water Board, and Nunavut Impact Review Board registries by Caslys Consulting Ltd. between 2000 and 2023. (Note this dataset extends across all of the NWT and into a portion of Nunavut to provide information across the Bathurst Caribou Range, which straddles the territorial boundary.).This was part of the Human Disturbance Mapping project for the GNWT, where a series of spatial datasets were created with the key objective to create an accurate and up-to-date human disturbance footprint that can be used to help make future land and water management decisions. These datasets were created based on existing baseline GIS data, aerial and satellite imagery, as well as permit records from registries with associated online archives..Modelling and other landscape GIS analyses that use this information may benefit from combining all point, line and polygon datasets into a single disturbance footprint that best represents the sum of all input files. It is recommended that this process be completed by first applying GIS buffer functions to point and line feature classes. This provides the advantages of having a more true representation of disturbance footprint with the ability to calculate spatially explicit functions, such as determining the area of the total disturbance. Using the ‘PointArea_Ha’ (Permit_Data_Points) and ‘LinearWidth_m’ (Permit_Data_Lines) fields respectively, users can calculate the buffer distance for each record in the point and line feature class files. The values in these fields do not represent the buffer distance itself, but can be used to calculate an appropriate buffer distance that can be added to an additional buffer-distance-field..Using the date fields and seasonal date fields, the user may develop queries that will allow human disturbance information to be displayed for a specific time period. Refer to Section 3.2 in the Human Disturbance Mapping Report (Caslys, 2015) which lists the fields that can be used to accomplish date-specific queries, as well as the Technical Guide - Selection by Date (Caslys, 2015) which outlines the query syntax..Along with the content created through this mapping project, several other GIS map layers should be used to create a comprehensive representation of the human disturbance footprint. Primarily, roads that have been previously mapped have not been re-captured under the scope of this project. Therefore, any modelling that is developed to map the human disturbance footprint should include other map layers managed by NWTCG. Refer to Section 3.1 in the Human Disturbance Mapping Report (Caslys, 2015) for a list of recommended map layers to be included in this process. As well, refer to the (NWT Cumulative Impact Monitoring Program) Inventory of Landscape Change Map Viewer to view a series of map layers that all contribute to the total development footprint.

TwitterThis dataset represents wetlands included in Vermont's Significant Wetlands Inventory. The State of Vermont protects wetlands which provide significant functions and values and also protects a buffer zone directly adjacent to significant wetlands. Wetlands in Vermont are classified as Class I, II, or III based on the significance of the functions and values they provide. Class I and Class II wetlands provide significant functions and values and are protected by the Vermont Wetland Rules. Any activity within a Class I or II wetland or buffer zone which is not exempt or considered an "allowed use" under the Vermont Wetland Rules requires a permit.Background: National Wetlands Inventory (NWI) maps were used by the State of Vermont, Agency of Natural resources as a means of creating this data layer in conjunction with the VSWI. The NWI and VSWI were joined by a union, to create the new 2010 Vermont Significant Wetland Inventory data layer, representing Vermont's regulatory wetlands. The VSWI prior to 2010 was created by hand digitizing nearly two-thirds of Vermont's wetlands from RF 24000 scale NWI mylars. The remainder of the state was scanned from RF 24000 or RF 25000 scale mylars. These mylars were created by transfering wetland polygon boundaries from RF 62500 scale NWI mylars to RF 24000 scale base maps.

TwitterThis layer is intended to provide estimates of nonpoint sources on the subwatershed (HUC-12) level in the state of Michigan. These include estimates of livestock agriculture (such as livestock numbers and manure land-application area), lost wetland, natural riparian buffers, and the amount of land that is covered by impervious surfaces. Each nonpoint source indicator (or stressor) is given a category based on how the subwatershed compares with all other subwatersheds in the entire state (e.g. a subwatershed that is marked as "high" for impervious surfaces would have a high amount of impervious surface relative to the state median value). Land cover (NOAA, 2023), population and housing unit data (US Census Bureau, 2020), agricultural census data (USDA, 2020), Michigan Department of Environment, Great Lakes, and Energy (EGLE) Water Resources Division CAFO permitting program (2025), and lost wetland (Fizzell, 2015) are summarized for each 12-digit HUC level subwatershed in Michigan. The number of hogs and cattle, and the percent of agricultural land that has manure land-applied or tiled, are estimates derived from county-based agricultural census and EGLE-WRD CAFO permitting data. The agricultural census county-level data were then distributed geographically across all agricultural land cover in that county, assuming even distribution or impact of a given stressor. EGLE-WRD CAFO permitting livestock data were evenly distributed across associated CAFO fields. Natural riparian buffer coverage is a percent of stream miles with a 30 meter natural vegetation buffer, and was created by buffering the stream hydrography layer and interesecting the buffer with forested and wetland 2023-era land cover.

TwitterThis layer contains the 23 National Priority Areas for Ecological Corridors (NPAECs) with their 30km buffer, identified by the Parks Canada’s National Program for Ecological Corridors. The NPAECs were identified based on a methodology that is multivariate, data driven, national in scale, and spatially explicit at a coarse resolution. Key methodological steps are described briefly on the Ecological Corridors Program mapping webpage (https://parks.canada.ca/nature/science/conservation/corridors-ecologiques-ecological-corridors/prioritaires-priorities).
The NPAECs are not ecological corridors. They are high priority areas across Canada identified as nationally important for connectivity conservation. NPAECs are broad areas where habitat loss and fragmentation have occurred or is imminent, and where the movement of many species across the landscape would be impacted if connectivity was lost. The priority areas can be thought of as national hot spots where ecological corridors are most needed. Supporting connectivity in these areas would have the biggest impact for sustaining biodiversity and ecological functions.
The NPAECs are large, coarsely defined geographic areas that should be displayed with blurred edges. The blurred boundary is a result of the underlying national-scale geographic and ecological data used to create the map. These data are coarse so precise linear delineation of hard edges around the priority areas was not possible, nor appropriate. NPAECs should therefore be represented with a 30km blurred buffer edge rather than a definitive boundary line. This data layer represents NPAECs with a 30km outward buffer already applied. The layer files include a symbology file that provides users with the intended visual aspect of the NPAEC.
