Abstract/Purpose/Disclaimer


Important Farmland Maps are compiled by the Farmland Mapping and Monitoring Program (FMMP) pursuant to Section 65570 of the California Government Code. To create the GIS data, FMMP combines current land use information with U.S. Department of Agriculture-Natural Resources Conservation Service (NRCS) soil survey data. Soil units qualifying for Prime Farmland and Farmland of Statewide Importance are determined by the NRCS. Changes to soil profiles subsequent to publication of NRCS soil surveys are not reflected in this data. This data was developed using NRCS digital soil data (SSURGO) and may contain individual soil units as small as one acre.

Land use status is determined using current and historic aerial imagery, supplemental GIS data, and field verification. Imagery sources may include public domain datasets, web-based information, and commercially purchased data, depending on data availability. Supplemental data on land management status is obtained from federal, state, and local governments. Map reviewers at the local level contribute valuable information with their comments and suggestions. Please refer to FMMP field analyst reports for each county to obtain specific citations.

This data should be used within the limits of its purpose - as a current inventory of agricultural land resources. This data does not necessarily reflect general plan or zoning designations, city limit lines, changing economic or market conditions, or other factors which may be taken into consideration when land use policies are determined. This data is not designed for parcel-specific planning purposes due to its scale and the ten-acre minimum land use mapping unit. Classification of important farmland and urban areas in this data is based on best available data. The information has been delineated as accurately as possible at 1:24,000-scale, but no claim to meet 1:24,000 National Map Accuracy Standards is made due to variations in the quality of source data. © 2012, California Department of Conservation All rights reserved. Fair use of this data for non-commercial, educational, research or scientific purpose is not a violation of copyright. However, no part of the contents of this data may be reproduced, transmitted, or distributed in any form or by any means, electronic or mechanical, for any purpose without the express written permission of the Department of Conservation, Division of Land Resource Protection.

Layout & Tools

CIFF 1.0 Desktop Status Menu
A status menu displays results of a status check of all spatial services used in CIFF. A status check is performed when CIFF is loaded.
1. All Services Online Description
Status Menu - All Services Online When the application detects all spatial services are online and loaded as services, the Status Menu will inform users that all spatial services are online. The status menu will close automatically after a few seconds.
2. One or More Main Services Offline Description
Status Menu - One Main Service Offline When the application detects one of the main spatial services (ESRI Street or Farmland) for whatever reason is inaccessible, the application will prevent users access to CIFF because both spatial services are required for CIFF to be useful. The Status menu will display the service that is inaccessible, and it will allow users to refresh the application and report the specific problem.
