Looking for 2018 NAIP imagery of California? The 2018 NAIP county mosaics are available for download now. The imagery is available in both natural color and near infrared.
What is NAIP? NAIP stands for the National Agriculture Imagery Program. NAIP acquires digital ortho imagery during the agricultural growing seasons in the continental US. NAIP provides 60 centimeter ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy within +/- 4 meters of reference digital ortho quarter quads (DOQQ’s) from the National Digital Ortho Program (NDOP) or from the National Agriculture Imagery Program (NAIP). The tiling format of NAIP imagery is based on a 3.75′ x 3.75′ quarter quadrangle with a 300 pixel buffer on all four sides. The NAIP imagery is formatted to the UTM coordinate system using the North American Datum of 1983 (NAD83). NAIP imagery may contain as much as 10% cloud cover per tile. This file was generated by compressing NAIP imagery that cover the county extent. Two types of compression may be used for NAIP imagery: MrSID and JPEG 2000. The target value for the compression ratio is 40:1 for imagery.
NAIP imagery is typically available for distribution within 60 days of the end of a flying season and is intended to provide current information of agricultural conditions in support of USDA farm programs. For USDA Farm Service Agency, the 1 meter and 1/2 meter GSD product provides an ortho image base for Common Land Unit boundaries and other data sets. NAIP imagery is generally acquired in projects covering full states in cooperation with state government and other federal agencies who use the imagery for a variety of purposes including land use planning and natural resource assessment. NAIP is also used for disaster response often providing the most current pre-event imagery.

Some notes about installing ArcGIS 10.7:
The ArcGIS 10.7 setup packages are designed to detect and upgrade an existing installation of the same ArcGIS product. The settings for the installation location and authorization information are retained during the upgrade. See the installation guide for more information on installation upgrades and new installations.
ArcGIS 10.7 Single Use Licenses:
If ArcGIS 10.7 will be installed on a machine that is different from where a previous ArcGIS 10.x product is currently installed and you wish to use the existing ArcGIS 10.1—10.6.1 authorization number for ArcGIS 10.7, the earlier version of an ArcGIS 10.x product must first be deauthorized before authorizing ArcGIS 10.7.
ArcGIS 10.7 Concurrent Use Licenses:
- The copy protection mechanism for ArcGIS Desktop 10.7 and ArcGIS Engine 10.7 Concurrent Use requires that ArcGIS License Manager 2018.1 be installed to support these products.
- Existing ArcGIS 10.1—10.6.1 authorization numbers will work with ArcGIS Desktop and Engine 10.7.
- Existing ArcGIS Enterprise 10.6—10.6.1 authorization numbers will not work with ArcGIS Enterprise 10.7. You must obtain a 10.7 authorization number.
