Class 0: Never Classified, Class 1: Unclassified, Class 2: Ground, Class 7: Low/High Point (Noise), and Class 12: Overlap. The following are the collection parameters and equipment used to create these data sets. Aircrafts: Cessna 320 (N3443Q) and Piper Navajo (N6GR) Lidar System: Optech ALTM Gemini (03SEN145) Approximate Collection Altitude (Above Mean Terrain): 1800 meters Ground Speed: 180 kts Pulse Rate Frequency: 70 kHz Mirror Scan Frequency: 40 Hz Scan Angle (+/-): 16 degrees Beam Divergence: Narrow (0.25 mrad) Accuracy statements are based on areas of moderate terrain, with points classified as ground. Diminished accuracies are to be expected in areas of extreme terrain and dense vegetation. The accuracy of each point is expected to meet the vertical accuracy standard, derived products may be less accurate in areas of extreme terrain and dense vegetation due to a lesser number of points defining the ground in these areas. Classified data sets such as this one may have varying posting due to some pulses not reaching the ground. Be aware the the Western Kenai Lowlands and Eastern Kenai Watershed have different accuracies and point spacings. Read this metadata record thoroughly to determine what the accuracies and point spacing are for your area of interest. USGS Contract No. 07CRCN0002 USGS Task Order No. 07002C0021. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. purpose: The purpose of this data set is to provide bare-earth processed lidar data over the western lowlands of the Kenai Peninsula, at a minimum point density of 0.5 points per square meter. status: (MD_ProgressCode) completed pointOfContact: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave city: Charleston administrativeArea: SC postalCode: 29405-2413 country: (missing) electronicMailAddress: coastal.info@noaa.gov onlineResource: (CI_OnlineResource) linkage: https://coast.noaa.gov protocol: WWW:LINK-1.0-http--link name: NOAA Office for Coastal Management Website description: NOAA Office for Coastal Management Home Page function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) pointOfContact pointOfContact: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave city: Charleston administrativeArea: SC postalCode: 29405-2413 country: (missing) electronicMailAddress: coastal.info@noaa.gov onlineResource: (CI_OnlineResource) linkage: https://coast.noaa.gov protocol: WWW:LINK-1.0-http--link name: NOAA Office for Coastal Management Website description: NOAA Office for Coastal Management Home Page function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) custodian resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) asNeeded descriptiveKeywords: (MD_Keywords) keyword: Bare-Earth keyword: Terrain type: (MD_KeywordTypeCode) theme descriptiveKeywords: (MD_Keywords) keyword: Lidar - partner (no harvest) type: (MD_KeywordTypeCode) project thesaurusName: (CI_Citation) title: InPort date: (inapplicable) resourceConstraints: (MD_LegalConstraints) useConstraints: (MD_RestrictionCode) otherRestrictions otherConstraints: Cite As: OCM Partners, [Date of Access]: 2008 Kenai Watershed Forum Topographic LiDAR: Kenai Peninsula, Alaska [Data Date Range], https://www.fisheries.noaa.gov/inport/item/49620. resourceConstraints: (MD_Constraints) useLimitation: NOAA provides no warranty, nor accepts any liability occurring from any incomplete, incorrect, or misleading data, or from any incorrect, incomplete, or misleading use of the data.

The Western Kenai Lowlands (Areas A,B,C,D,E) have a horizontal accuracy of 0.7 meter, with a nominal point spacing of 1.4 meters as per manufacturer's specifications, not field verified. The Eastern Kenai Watershed (Areas F,G,H) has a horizontal accuracy of 2.0 meters, with a nominal point spacing of 3.0 meters, not field verified. See map in Supplemental Information above for Area Index. ; Quantitative Value: 2.0 meters, Test that produced the value: Horizontal accuracy in meters, not tested, for the Eastern Kenai Watershed (Areas F,G,H). The Western Kenai Lowlands (Areas A,B,C,D,E) have horizontal accuracy closer to .7 meters, not tested. See map in Supplemental Information above for Area Index. result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Vertical Positional Accuracy evaluationMethodDescription: These values were computed by verifying the ground classified lidar data against ground surveyed points in the land cover categories as described by FEMA. The points were collected throughout the project area, by DOWL/HKM. We recommend additional ground truth surveys of the data set to verify the vertical accuracy has not changed due to natural causes, such as techtonic motion or freeze/thaw cycles, and non-natural causes such as road construction. Without ground truth survey checks this data is not recommended for design grade mapping or engineering. ; Quantitative Value: 0.47 meters, Test that produced the value: Fundamental vertical accuracy in meters at the 95th percentile in open terrain for areas the Eastern Kenai Watershed (Areas F,G,H). The Western Kenai Lowlands (Areas A,B,C,D,E) have vertical accuracy closer to .10 meters FVA at the 95th percentile in open terrain.

Data was collected at the same settings as this project, using two intersecting perpendicular lines. Two GPS ground stations were operating on site in order to minimize GPS error. The data was classified in each line separately for ground and other common features between lines, such as building roofs. This data was processed in TerraMatch 8.001 (TerraSolid, Ltd.), to compute corrections for roll, pitch, heading, and mirror scale. These corrections were applied to the initial processing settings (.res file). The data was reprocessed to verify the corrections were applied properly. The corrected data was then compared to ground surveyed measurements in order to check for any consistent vertical bias. The final step in calibration verified there was minimal vertical noise due to changes in intensity. This was done by comparing elevations of points on the airport runway, one point on a runway stripe and another adjacent point on the pavement. dateTime: DateTime: 2008-06-10T00:00:00 processStep: (LI_ProcessStep) description: Create a smoothed-best estimated trajectory (SBET) of the sensor at a rate of 200 Hz, by integrating the airborne GPS and IMU data The basis of the GPS coordinates were provided to Aero-Metric by DOWL/HKM, and were referenced to NAD83 (CORS96) with GEOID06 derived orthometric heights. The maximum baseline distance for this area was 23 km, the average base line length was 15 km. The mean GPS positional accuracy for this area was +/- 0.05 meters. dateTime: DateTime: 2008-07-28T00:00:00 processStep: (LI_ProcessStep) description: Integrate SBET and raw laser data to produce point cloud data in LAS 1.1 format for each flight line. dateTime: DateTime: 2008-07-28T00:00:00 processStep: (LI_ProcessStep) description: Compute the roll, pitch, heading, and mirror scale correction factors for each flight line, then apply corrections to the corresponding flight line. dateTime: DateTime: 2008-07-28T00:00:00 processStep: (LI_ProcessStep) description: Automated classification of the bare-earth data from the lidar point cloud using a series of algorithms customized for the types of terrain encountered in the project. dateTime: DateTime: 2008-08-21T00:00:00 processStep: (LI_ProcessStep) description: Manual classification of any data which appears to be bare-earth but was not properly classified using the automated methods. dateTime: DateTime: 2008-08-22T00:00:00 processStep: (LI_ProcessStep) description: Create point clouds in LAS 1.1 format for all returns. dateTime: DateTime: 2010-01-21T00:00:00 processStep: (LI_ProcessStep) description: Data verified using survey control points, located throughout the area. dateTime: DateTime: 2009-10-02T00:00:00 processStep: (LI_ProcessStep) description: Metadata updated for Bounding coordinates, Spatial Reference info using FGDC template dateTime: DateTime: 2010-01-21T00:00:00 processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received the topographic files in LAS V1.1 format. The files contained lidar elevation and intensity measurements. The data were received in Alaska State Plane Zone 4 (FIPS 5004), NAD83 coordinates and were vertically referenced to NAVD88 using the Geoid06 model. The vertical units of the data were feet. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The User_Data field of the LAS files' header was set to a value (0-7) to reflect the LiDAR Data Areas (Area A: 0, Area B: 1, Area C: 2, Area D: 3, Area E: 4, Area F: 6, Area G: 5, Area H: 7) 2. The classification scheme was rearranged. Class 10 (High Noise) was combined into Class 7 (Low Noise). Class 11 (Single Return, not ground) was reclassified as Class 10. Class 13 (1st return of many returns) was reclassfied as Class 14. Class 14 (2nd return of many) was reclassified as Class 15. Class 15 (3rd of many returns) was reclassified as Class 16. Class 16 (Last return of many) was reclassified as Class 17. (see next processing step for further changes) 3. The topographic las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid06. 4. The topographic las files were converted from a Projected Coordinate System (AK SP Zone 4) to a Geographic Coordinate system (NAD83). 5. The topographic las files' vertical units were converted from feet to meters. 6. The topographic las files' horizontal units were converted from feet to decimal degrees. dateTime: DateTime: 2013-07-01T00:00:00 processor: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management simplified the classification scheme because the classes signifying return numbers were replicating information already in the files.
