Where to download 4-band NAIP imagery for California?
Earth Explorer is an invaluable source for NAIP imagery. Access these images using the following steps:
- Define your area of interest in the "Search Criteria" tab. Here you
can specify a county in CA by navigating to the
Predefined Area tab > Add Shape > California > County > YourCounty - Select data:
Data Sets tab > Aerial Imagery > NAIP JPG2000 - Select your images and download them
The Cal-Atlas site has 2012 NAIP R,G,B,NIR quarter-quad tiffs available for download.
The USDA-APFO provides a REST ArcGIS webmap service which now contains the NIR band. To use this service you will need to add a GIS Server in ArcGIS.
1) Open ArcCatalog and in the Catalog Tree select "GIS Servers" 2) Double click "Add ArcGIS Server" 3) In wizard select "Use GIS Services" and click next 4) Under "Server URL" enter "gis.apfo.usda.gov/arcgis/services" and click finish.
This service will then be available in ArcGIS through add data. Just click the add data button, under the "Look in" drop-down (at top) select "GIS Servers" and double click the service that you added "arcgis on gis.apfo.usda.gov (user)". Navigate to NAIP and the state you would like and you will get a state-wide mosaic.
