BUT you will have to re-compile your changes in order to make the ArcToolbox an add-on again.
Those interested in the source code can see that as well.
Most Users can simply download the "OpenFields.esriaddin" and install it. It simply performs the spatial analysis needed for Farmland assessment, all value calculations are done in your county CAMA system. Please note: THIS TOOL DOES NO FARMLAND VALUATION. Just installing the addon should be straightforward OR you can modify the Python for your own customization. The tool has well documented help and was build using Python. Options for Flood debasement or deeded acreage are available.
The outputs are Shapefile plus CSV to TXT for importing the results into a County CAMA system. It takes your Existing Three layers: Land Use, Parcels and Soils and performs a geoprocessing Union based on Parcel Number. This project is owned by Cloudpoint Geographics Inc. It will be discarded, but you can do field mapping to map a field of the input feature class to a field of the output feature class.This is an ArcMap (10.1 - 10.6) Addon for Farmland Assessment in Illinois. If the fields in the input feature class attribute table are not in the output feature class attribute table Attribute table: The attribute table of the same output feature class. append does not process the elements, it simply puts the elements into a feature class, so the output feature class may be heavy Graphics: append can merge feature classes such as points, lines, and polygons with tables, raster images, and raster catalogs, but they must be of the same class The section name, type, and arrangement order must be exactly the same, and can be different when the schema type option is no_test. When the schema type option is test, the input and output feature class attribute table structure must be consistent, both Merge can perform field mapping.ģ, the append : Merge the input feature class, table, raster images and raster catalog to an existing feature class, table, raster imageĪnd raster catalogs. Attribute table: When merge processing the attribute table, the fields with the same name will be combined into one, and the fields with different names will be in the original name and orderĪll added to the output feature class attribute table, the original fid will be discarded. , Simply put the features into a feature class, so the output feature classes may have overlaps or gaps. Graphics: merge can merge feature classes and tables such as points, lines, and polygons, but they must be of the same type. Union does not do field mapping.Ģ, Merge : merging the input feature class, the new table to the feature class table. In the attribute table of the class, add the feature class name after fid to show the difference. only_fid only two feature class attribute table in fid in the output element The order is all placed in the attribute table of the output feature class. no_fid sorts the fields except the fid in the attribute table of the two feature classes Fields with the same name (except for fid ) after the field nameĪdd numbers to show the difference ( fid plus the name of the feature class). The table fields are all placed in the attribute table of the output feature class in sequence, including fid. Attribute table: There are three options for union merge attribute table: all, no_fid and only_fid. The combined gaps of the two feature classes will generate features. Into multi-component elements, and there are options to allow gaps ( gaps ) or not. When the two feature classes are merged, the intersection will be processed to make them separate. Graphics: union can only merge feature classes of polygon type. 1, Union : the input feature class merging into a new feature class. The following two figures are the graphics and attribute tables of two feature classes a and b : The main differences between them are introduced below. Although they can combine two feature classes into one feature class, they have different functions. Tools in arctoolbox that combine two feature classes into one are mainly union, merge and append.
The main differences between union, merge and append The
