How to Use ModelBuilder Part 5
 
08:30
Fifth video in a series on how to use ModelBuilder in ArcGIS 10.3 to automate geoprocessing tasks. The goal is to build our model to take Boston 311 data, map the data, aggregate it by neighborhood, calculate a series of normalized indices, and output properly symbolized feature layers. In this video we create symbolized output for the model. Layer files with desired symbology for each variable are first created in ArcMap. Within the model, we use the Make Feature Layer tool to create three feature layers. We then use the Apply Symbology from Layer tool to output three properly symbolized layer files of the processed data in to ArcMap.

The goal is to build our model to take Boston 311 data, map the data, aggregate it by neighborhood, calculate a series of normalized indices, and output properly symbolized feature layers. In this video we parameterize the model to allow it to be run as a tool from ArcCatalog and also allow a user to specify an input file. Finally, we enable layer files to be properly output to ArcMap at the conclusion of the process.

Seventh video in a series on how to use ModelBuilder in ArcGIS 10.3 to automate geoprocessing tasks. The goal is to build our model to take Boston 311 data, map the data, aggregate it by neighborhood, calculate a series of normalized indices, and output properly symbolized feature layers. In this video we use inline variable substitution to control naming of output layer files and how other output are named. We insert a new variable into the model which is set as a parameter allowing the user to specify the year of the data. This year is then input as inline variable substitute into the names of the feature classes and also into a new permanent feature class output.

Fourth video in a series on how to use ModelBuilder in ArcGIS 10.3 to automate geoprocessing tasks. The goal is to build our model to take Boston 311 data, map the data, aggregate it by neighborhood, calculate a series of normalized indices, and output properly symbolized feature layers. In this video we calculate the percentage of overdue Boston 311 reports by neighborhood. The neighborhood layer is spatially joined to the event theme, events that are marked as "overdue" are isolated using the Select tool, and summary statistics are calculated of those overdue reocords, producing a table with a count of overdue reports within each neighborhood. The latter is then joined to the output feature class and the percentage of overdue reports per neighborhood is calculated.
