Description: This feature class provides addresses for every building, house, apartment, or condo unit in Los Alamos County. The points are the center of the building or unit for which they represent. The addresses were checked visually in August and September 2015, and have been reconciled against the county surveyor's records.
Description: Point features for DPU-owned and privately-owned water fire hyrdants. Includes data such as technical characteristics, condition, intallation year, and last inspection year.
Description: This layer has the roads for Los Alamos County, plus a few highways leading out of the County which are included for 911 response purposes (but are not maintained by the County).The geometry is all digitized from aerial photos. In Los Alamos and White Rock, the source is the 2014 Pictometry orthoimagery, while in the more remote areas, the source is either the 2014 NAIP data or the 2011 post-Las Conchas fire orthoimagery. Road segments are entire between intersections, but are split at all intersections. The location of the road centerlines should be accurate to within 1-3 feet depending on the source data.LANL roads are included, though in most cases these are off limits to unauthorized invididuals. At a minimum, most LANL roads will require a LANL badge for all vehicle occupants. Many of the more remote LANL roads are gated and require additional clearance, keys, etc. No guarantee is made about the accuracy of these data for navigating LANL roads, as changes can and do occur based on LANL's needs.Forest roads are included, but in some cases sections will have been washed out by floods, so not all forest roads may be accessible. Additionall, all forest roads are rough, and require four wheel drive vehicles with high clearance. No guarantee is made about the accuracy of these data for navigating forest roads, as changes can and do occur based on weather.Bandelier National Monument roads are included, but some are for staff only, while others may limit vehicular traffic during peak periods (summer) when buses run from White Rock. No guarantee is made about the accessibility of any Bandelier road, as changes can and do occur based on the park's needs.There are a number of attirbutes included in this layer such as road function, substrate, ownership, speed limit, # of lanes, and 911-relevant addressing fields.The address ranges were manually checked against known address points in 2016 for consistency.
Description: This is the definitive county boundary, based on published plats, survey data, and GPS'd boundary markers. As opposed to other Los Alamos County boundary layers, such as in Google Maps, Esri map services, Bing, or those published by TIGER or the New Mexico GIS clearinghouse, this county boundary layer is updated frequently, as Los Alamos County GIS continues to find the boundary markers that define its borders on the ground. The goal is to have all the border points and angle points GPS'd and accurate to within 12 inches. Where markers are missing, these points are derived from published plats and surveys.
Description: This layer shows the footprints of buildings, based on the 2014 Pictometry data, and in some cases on LANL (where Pictometry isn't available), based on the 2011 12-inch imagery from the Las Conchas fire. The layer includes permanent structures as determined by the GIS Administrator, Temporary buildings are not included, though sheds in many cases are (where they appear to be long-term).
Description: This layer is updated every 6-12 months, and is based on hand-drawn delineations of fire districts by LAFD. The districts are intended to balance the demand for service with the resources available. The lines are recreated in GIS with LAFD staff on hand to supervise. These lines also drive the 911 dispatch and are part of the CAD system.
