NAIP (National Agriculture Imagery Program) Imagery

The National Agriculture Imagery Program (NAIP) is a program to acquire peak growing season “leaf on” imagery, and deliver this imagery to USDA County Service Centers, in order to maintain the common land unit (CLU) boundaries and assist with farm programs.

This data is different from our LARIAC imagery because it contains a 4th […]

2014 Color Orthophotography – LARIAC4

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 2013/2014. 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, […]

Imagery of Southern California (Orange, Riverside, San Bernardino Counties) – 2014

USGS has now posted 2014 imagery for a portion of the southern California urban region.

The images have a one foot resolution […]

LARIAC4 (2014) 4-inch and 1 foot Orthophoto Imagery Seamline and Date Flown

These dataset contains the dates of the imagery as well as the image chips that were compiled into the 2014 Los Angeles Regional Imagery Acquisition Consortium (LARIAC4) 4-inch and 1-foot color orthophotography.

Each polygon contains an 8 digit number that corresponds to the date the image was acquired (for example, 20140125 corresponds to […]

Historic Maps of Los Angeles City (1849, 1908)

Two georeferenced images of historic maps of Los Angeles were downloaded from Earthworks, as posted by SoCalGIS. Since they were georeferenced I thought they might be of interest.

Many thanks to Harvard University Library for scanning and georeferencing these maps.
