On November 7, 2021, NV5 collected Quality Level 1 (QL1) lidar data across the preliminary CAL FIRE defined fire perimeter for the CZU lightning complex fire in San Mateo and Santa Cruz counties. The technical report for the lidar data collection is available here: https://fuelsmapping.com/czu_postfire_lidar_report From the QL1 postfire lidar, NV5 and Tukman Geospatial developed a set of derivatives. These derivatives are a Digital Terrain Model (DTM), a Digital Surface Model (DSM), a Hillshade derived from the DTM, a lidar intensity image, a Normalized Digital Surface Model (nDSM), a Canopy Cover raster, and a lidar intensity image. The derivatives will be used to study the effects of the CZU wildfire on the natural landscape, forests, and shrublands of Santa Cruz and San Mateo Counties. The lidar derivatives are provided as GeoTiffs available for download from ArcGIS Online and as dynamic image services. Table 1 provides more information (including download information) for the derivatives produced. The GeoTiffs can be used in desktop GIS software packages such as ArcGIS Pro and ERDAS Imagine; the image services can be used in web maps and web mapping applications by both GIS users and non-GIS users.

  Digital Terrain Model (DTM)


  Hydroflattened digital terrain model. Pixel values represent elevation above sea level of the ground.


  https://vegmap.press/czu_postfire_dtm_tif


  https://vegmap.press/czu_postfire_dtm




  Digital Surface Model (DSM)


  Pixel values in the DSM represent elevations above sea level of the ‘highest hit’ surface. The DSM provides elevation above sea level of the top of the tree canopy, the top of buildings, and the top of other features.


  https://vegmap.press/czu_postfire_dsm_tif


  https://vegmap.press/czu_postfire_dsm




  Hillshade


  The hillshade is derived from the DTM and provides a ‘shaded relief’ visualization of the earth’s surface.

  Lidar Intensity


  Lidar intensity, scaled to 8-bit resolution.


  https://vegmap.press/czu_postfire_intensity_tif


  https://vegmap.press/czu_postfire_lidar_intensity




  Normalized Digital Surface Model (nDSM)


  In the nDSM, pixel values represent the maximum normalized height in feet of features such as vegetation and structures. For areas with aboveground features, pixel values represent the aboveground height of the tallest part of the feature in the 3x3 foot pixel. For areas with no aboveground features, the nDSM has pixel values of 0. 


  https://vegmap.press/czu_postfire_nDSM_tif


  https://vegmap.press/czu_postfire_nDSM




  Canopy Height Model


  The canopy height model is the normalized digital surface model, with building footprints and a small buffer surrounding them set to 0 normalized height. Building footprint data came from the prefire CHM. The datasheet for the prefire CHM is available here: https://vegmap.press/sc_chm As such, this raster mostly represents the aboveground height of the vegetation canopy.  Note that it also includes some noise (e.g., powerlines and other objects that are not vegetation), as well as some structures that weren't captured as building footprints.


  https://vegmap.press/czu_postfire_chm_tif


  https://vegmap.press/czu_postfire_chm




  Canopy Cover


  This is the Canopy Height Model, thresholded to show pixel values greater than or equal to 15 feet aboveground as 1, and all other areas as 0. As such, it is a proxy for tree canopy cover.

The U.S. Geological Survey, in partnership with the National Park Service's Colonial National Historic Park (COLO), used commercially available satellite data and soil samples from around Jamestown Island to evaluate vegetative health and soil conditions on the island to further understand the extent and severity of conditions that threaten archaeological sites and vegetation. 50 sites were initially selected for sampling, however, only 48 of the sites were accessible in either June 2021 or March 2022. The soil samples were collected from 2 depths at 48 different sites around the island. The first sample was collected just below the land surface in the O horizon, and the second sample was collected from a minimum of 0.34 ft below the land surface in the A horizon. Two soil sampling efforts were conducted, one in June 2021 and a second in March 2022 to represent drier and wetter times of the year. Measurements of temperature in degrees Celsius, moisture content in percent volume, and soil conductivity in millisiemens per centimeter, were made using a Dynamax WET-2 sensor. Soil pH was also measured using the U.S. Environmental Protection Agency's 9045D method. Satellite imagery, multispectral and panchromatic images, used in the project come from the GeoEYE, QuickBird 2, WorldView 2, and WorldView 3 satellites operated by the European Space Agency and Digital Globe . USGS used panchromatic and multispectral images of Jamestown Island taken from 2010 – 2018 to create Normalized Difference Vegetative Index (NDVI) and difference of NDVI rasters to evaluate vegetative stress across Jamestown Island over time. The images used were acquired using the USGS's Commercial Remote Sensing Space Policy (CRSSP) Imagery Derived Requirements (CIDR) tool. The search terms used for the CIDR request were for multispectral and panchromatic images of Jamestown Island, VA at a standard (2A) processing level with an image resolution of 1-4m, a max cloud cover of 20%, from 05/01/2008 - 07/28/2022. The search returned 12 images, or scenes, of which 4 were used for the associated publication. The collection dates, satellite platform and panchromatic and multispectral ground sample distances (GSD) respectively are as follows: - 11/28/2010 at 16:24 from WorldView 2; GSD 1.509 ft and 5.906 ft - 06/25/2011 at 15:56 by GeoEye; GSD 1.345ft and 5.413 ft - 10/10/2011 by QuickBird 2; GSD 2.001 ft and 7.874 ft - 2/12/2018 at 16:08 by WorldView 3; GSD 1.017 ft and 4.068 ft The multispectral images were pan-sharpened to increase the resolution for visual light rasters of Jamestown Island using ESRI ArcGIS Pro's Pan-Sharpen tool utilizing the Graham-Schmidt method. Additionally, the 4 multispectral images were used to create normalized difference vegetative index rasters using the ESRI ArcGIS Pro NDVI tool. For images with multiple near-infrared (NIR) bands, the first NIR band was used to create the NDVI rasters. A difference of NDVI raster was created using the Raster Calculator tool in ArcGIS Pro to show change in vegetative heath over time. The 11/28/2010 WorldView 2 and 12/12/2018 WorldView 3 NDVI rasters with water removed from the rasters were used to create the difference of NDVI raster. The GSD for the difference of NDVI raster is 5.906 ft. The original multispectral and panchromatic images could not be published in this data release as the rights for those images belong to European Space Agency or Digital Globe. As such only the derived products, the pan-sharpened image, NDVI rasters, and difference of NDVI raster have been published in this data release.

This document describes the methodology behind the Housing Affordability Dashboard (2025–2030). It includes details on the datasets used (U.S. Census Bureau ACS, HUD housing data, and local datasets), preprocessing steps such as data cleaning and normalization, and the geospatial techniques applied in ArcGIS Pro and ArcGIS Online. The methodology also explains affordability metrics, how they were calculated, and the workflow for integrating results into the dashboard. The goal is to ensure transparency, reproducibility, and clarity in how housing affordability patterns were derived and presented.
