USGS Earth Explorer This dataset represents natural color, leaf-off, 1 foot high-accuracy orthorectified aerial imagery, acquired by the Los Angeles Regional Imagery Consortium (LAR-IAC) in winter 2010/2011, and made public with the partnership of the US Geological Survey (USGS). The DEM represents bare earth, whereas a related product (DSM) contains elevations and includes [...] This dataset contains the dates of the imagery compiled into the 2011 Los Angeles Regional Imagery Acquisition Consortium 4-inch and 1-foot color orthophotography. We are currently waiting for one final block to be added to this dataset (the National Forest north of Santa Clarita). Each polygon contains a 8 digit number [...] This dataset represents natural color, leaf-off, 0.33-foot (4-inch) high-resolution, high-accuracy orthorectified aerial imagery, acquired by the Los Angeles Regional Imagery Consortium (LAR-IAC) in winter 2010/2011. This imagery covers the majority of urban/suburban areas of the County in mainland (approximately 2,898 square miles) and Catalina Island covering approximately 75 square miles. The rest of the County, [...] LAR-IAC3 AT Block Layout (and links to LAR-IAC and LAR-IAC2 data grids). [...] The Cal-Atlas site facilitates the coordinated and sustainable development, maintenance, licensing and sharing of geospatial data and web map services by California government agencies, partners and stakeholders. California government agencies work with the California GIS Council, regional GIS collaboratives and the broader California GIS community to define the data architecture, systems, standards, agreements and processes [...] Defense Meteorological Satellite Program (DMSP), low, earth-orbiting satellites have provided the military with important environmental information. Some cool things you can find: Nighttime lights of the world – – here’s a KMZ file I downloaded: DMSP_Nighttime_Lights.kmz Visible and Infrared imagery Link to their sensors: http://www.ngdc.noaa.gov/dmsp/sensors.html The DMSP satellites “see” such environmental [...] This aerial imagery was captured in 2001 in a cooperative project between the Los Angeles County Department of Public Works and Regional Planning. It represents the initial imagery capture by the County of Los Angeles, which later become the Los Angeles Regional Imagery Acquisition Consortium (LAR-IAC). Three imagery resolutions were captured: 1 foot [...] This data is 6-inch color orthophotography flown the week of February 15th, 2010 to document the impact of debris flows February 6th, 2010. Coverage Area (with Station Fire Perimeter) On the morning of February 6th, 2010, the community of La Canada Flintridge saw a major debris flow on a number of streets [...]
Color Infrared, leaf-off, 0.33-foot (4-inch) high-resolution, high-accuracy orthorectified aerial imagery, acquired by the Los Angeles Regional Imagery Consortium (LAR-IAC) in winter 2005/2006. Infrared is an additional wavelength of information that can be captured by many aerial photography sensors in addition to the general Red/Green/Blue (RGB) channels typical to most imagery. The [...] Countywide Coverage Natural color, leaf-off, 1-foot high-resolution, high-accuracy orthorectified aerial imagery, acquired by the Los Angeles Regional Imagery Consortium (LAR-IAC2) in early 2008. This imagery covers the National Forest areas of the County, approximately 1,056 square miles, and is a separate dataset. The urban/suburban areas of the County in mainland (approximately 2,898 [...] Coverage Natural color, leaf-off, 1-foot high-resolution, high-accuracy orthorectified aerial imagery, acquired by the Los Angeles Regional Imagery Consortium (LAR-IAC) in early 2006. This imagery covers the National Forest areas of the County, approximately 1,056 square miles, and is a separate dataset.
