Warrant Visualization and Mapping : Progress Report Prepared for the New Braunfels Police Department

Background Using automated GIS tool to map un-served warrants Visualization Data Management Proactively pursue outstanding warrants Planning operations Increase safety More efficiently and effectively manage outstanding warrants

Scope Based on needs assessment conducted on February 7 th : Limited to the local area Within the Extra-Territorial Jurisdiction Limited to Class C Misdemeanor warrants All deliverables by the 4th of May 2012

New Braunfels ETJ The ETJ is the only area NBPD can serve warrants

Phases Phase I: Data Preparation/ File Conversion Phase II: Basic Warrant Tool Development Phase III: Advanced Tool Construction Phase IV: Tool Proofing and Refinement

Phase I: Data Collection Task 1 Data Collection Completed:Obtain sample.xml data In Progress:None To Do:None Objective: collect samples from the CRIMES warrant database and prepare “scrubbed” warrant files for geocoding.

Phase I: Data Preparation Task 2: Data Conversion Python script.xml to.csv converter script tool Batch multiple.xml files Generates a singular comma separate value (.csv) file containing data of all the warrant information. Labels the column with the correct attribute header and populates each field. ArcGIS supports.csv file extension and interprets the data into tabular format. Batching

Phase I: Data Preparation Task 3: Testing of Converted Files Template.csv file: warrant_output.csv. Mock Data.csv file: warrant_output2.csv - populated with 16 mock warrant data to include addresses out of the Extra-Territorial Jurisdiction (ETJ). Six (6) records of which were created with zip codes outside of New Braunsfels ETJ. We did this to test the accuracy of the geocoding tool and to test for filtering of non- local addresses

Phase II: Basic Warrant Tool Development Objective: Develop the prototype geocoding tool design. Task 1 Create composite address locators Method 1: Complete Built composite address using point and centerline. Pros- custom tailored to clients' needs. Streamlined for accuracy vs pre-made locators Cons – runs the risk of being outdated if data files are not updated.

Phase II: Basic Warrant Tool Development Objective: Develop the prototype geocoding tool design. Task 1 Create composite address locators Method 2: Complete Built composite address using City of New Braunfels address locator. Pros- locators are maintained by the GIS department and resides on the server. Easier to incorporate tool with existing resources on server. Cons – less accurate in terms of street matching.

Phase II: Basic Warrant Tool Development Objective: Develop the prototype geocoding tool design. Task 2: Building of geocoding model In Progress Complete Automation Filtering of non local warrant data. Automate the conversion of initial and subsequent updating of warrant data into tool. In addition to the composite address locators, a model has been built to identify zip codes outside of the New Braunfels' Extra-Territorial Jurisdiction (ETJ) and filter the records of non local warrant data.

Phase II: Basic Warrant Tool Development Objective: Develop the prototype geocoding tool design. Task 3: Geocode Test File CompleteTest run model by geocoding 16 mock warrant data records. 100% of the six records with non-local were identified and filtered.

Phase III: Advanced Tool Construction Pros-Simplicity in visualization Cons – Runs the risks of being outdated. Requires the layers to be regularly updated. Objective: enhancement of the geocoding tool to include background base layers, database management and map design and visualization. Task 1: Implementation of additional map layers Method 1: In Progress Use of individual base background layers.

Phase III: Advanced Tool Construction Pros-Updated by CoNB. Provides full extent of New Braunfels in various zoom levels. Rich visualization. Cons – more elaborate design with map layers that may not pertain to the NBPD needs. Objective: enhancement of the geocoding tool to include background base layers, database management and map design and visualization. Task 1: Implementation of additional map layers Method 2: In Progress Use of City of New Braunfels tiled map for base background layer.

Phase III: Advanced Tool Construction Geodatabase Warrant tool will be installed in a geodatabase format configuable with New Braunfels GIS servers. replicate the workspace environment as close as we possible to make it configurable to the ArcSDE environment. Modifications will be configured by IT or GIS personnel to make this tool accessible in ArcSDE environment. Objective: enhancement of the geocoding tool to include background base layers, database management and map design and visualization. Task 2: Creation of geodatabase and map document CompleteDesign model using file geodatabase workspace for input (warrant data), scratch (intermediate files), and output (output, final workspace)

Phase III: Advanced Tool Construction Objective: enhancement of the geocoding tool to include background base layers, database management and map design and visualization. Task 4: Reference Map Design Complete At this time, we have decided to use Manifold as our visualization platform. Task 3: Model Streamlining To Do Improve the model to make implementation as smooth as possible and to reduce errors. Phase III has been revamped to focus more on streamlining the model process.

Phase IV To Do Data Recycling Warrant Model Installed/Tested on NBPD Server Troubleshooting Additional Project Considerations

Phase IV Data Recycling Begins with external or internal conversion process New active warrant files must be first correctly sourced Various methods… Available conversion software (Novyxis): extra cost Existing script: extra time Encode system produces acceptable table formats: external forces Regular model “feeding” “Manual automation”

Phase IV Warrant Model Installed/Tested on NBPD Server Need for the final output available to entire NBPD Accessed, updated, and edited through… ArcMap ArcCatalog Successful Integration dependent upon… Our Warrant File Geodatabase and Your NBPD Server compatibility “Hollow” tool

Phase IV Troubleshooting Reserved for final model streamlining Possible conflicts include… NBPD Server and warrant model incompatibility Feeding the model and producing inaccurate address points Frequency, intensity, and volume of.xml files and efficient recycling Assessing unforeseen errors

Phase IV Additional Project Considerations Web Mapping Service Utilizing NBPD ArcSDE Server Integrating warrant geodatabase online Creating night/day base maps Query operations

Updated Schedule Adjustment for the extension of file conversion step Phase II begun 3 weeks early Phase III moved up 1 week, cut short 1 week Phase IV increased by 1 week Disadvantage File conversion more difficult Vital to model efficiency Advantage Allowed simultaneous development of several phases Better integration of various model “organs”
